[alsa-devel] Strange bug in .asoundrc ??
by Dominique Larchey-Wendling 19 Nov '07

19 Nov '07

Dear all, It seems that neither the current ctl.hw function nor the following simplified function ctl.!hw work correctly when the argument CARD is given to the function. It works however when no argument is given as the following test examples show it. It have alsa-lib version 1.0.14-0.4.rc3.fc7 installed on FC7. Is this a know bug of alsa-lib ? It is strange because this bug does not show up with pcm.hw for example. --- .asoundrc ------------------------ ctl.!hw { @args [ CARD ] @args.CARD { type string default "0" } type hw card $CARD } ctl.rha "hw" ctl.tata "hw:0" ctl.toto "hw:1" ------------------------------------------------ rha % amixer -D rha info Card rha 'Intel'/'HDA Intel at 0xfebfc000 irq 16' Mixer name : 'SigmaTel STAC9200' Components : 'HDA:83847690' Controls : 6 Simple ctrls : 4 rha % amixer -D tata info ALSA lib control.c:781:(snd_ctl_open_conf) Invalid type for CTL tata definition amixer: Control device tata open error: Invalid argument rha % amixer -D toto info ALSA lib control.c:781:(snd_ctl_open_conf) Invalid type for CTL toto definition amixer: Control device toto open error: Invalid argument

[alsa-devel] No sound on Intel DQ965GF motherboard
by Eric S. Raymond 19 Nov '07

19 Nov '07

Thank you, alsa developers, for the prompt resolution of my previous sound issue with the Thinkpad X61. Unfortunately, I've now turned up an apparently different problem on very similar hardware. Sound doesn't work on my DQ965GF motherboard under Ubuntu 7.10. Here's what I've found out about it. I'm writing in hope that someone on the ALSA devel list can suggest diagnostics to pin down the problem exactly. The device has PCI ID [8086:284b] (rev 02). It is an Intel 82801H. This appears to be an Ubuntu-specific error. At http://www.linuxquestions.org/questions/linux-hardware-18/intel-dq965gf-mob… I found a post implying that at least the rear jacks on the mobo are active under Fedora Core 6. I have therefore filed an Ubuntu bug at https://bugs.launchpad.net/ubuntu/+bug/162410 but seen no response. This also appears to be a very hardware-configuration-specific error. I have an Intel HDA audio device on my X61 laptop with PCI ID [8086:284b] (rev 03), another 82801H, that works just fine under Ubuntu 7.10 (the alsa version is nominally 1.0.14 but some 1.10.15 fixes, including the right one, were backported). Note the 03 as opposed to 02 subrev. aplay -l, which is supposed to list sound playback devices, returns no listing on the DQ965GF. As a check, on the X61 where it works it returns this: card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 lsmod also returns suggestively different results. On the laptop, its output includes this line. snd_hda_intel 337192 1 On the DQ965GF, here are the sound device lines: snd_hda_intel 337192 0 snd_usb_audio 96640 1 snd_pcm_oss 50048 0 snd_mixer_oss 20096 1 snd_pcm_oss snd_pcm 94344 3 snd_hda_intel,snd_usb_audio,snd_pcm_oss snd_usb_lib 20352 1 snd_usb_audio snd_seq_dummy 5380 0 snd_seq_oss 36864 0 snd_seq_midi 11008 0 snd_seq_midi_event 9984 2 snd_seq_oss,snd_seq_midi snd_seq 62496 6 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_timer 27272 2 snd_pcm,snd_seq snd_rawmidi 29824 2 snd_usb_lib,snd_seq_midi snd_seq_device 10260 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq,snd_rawmidi snd_hwdep 12168 1 snd_usb_audio snd 69288 13 snd_hda_intel,snd_usb_audio,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_seq_oss,snd_seq,snd_timer,snd_rawmidi,snd_seq_device,snd_hwdep soundcore 10272 1 snd snd_page_alloc 12560 2 snd_hda_intel,snd_pcm usbcore 161584 8 usbhid,snd_usb_audio,snd_usb_lib,xpad,gspca,ehci_hcd,uhci_hcd Note that snd_hda_intel has no users and that snd_usb_audio has 1. On the DQ965GF, the Sound Preferences tab on my Gnome toolbar thinks the sound device is "USB Device 0x46d:0x8ad (ALsa mixer)". I don't know what tool GNOME is running to determine this. This arch-linux thread gave me some insight: http://bugs.archlinux.org/task/6617 It appears the snd_usb_audio driver is a red herring, or at least a separate bug. I checked, and my dmesg log does indeed say "hda-intel: no codecs found!" on boot, which suggests that snd_hda_intel is loading and then failing to initialize properly, accounting for the usage count of 0. I tried reverting the kernel patch mentioned in the arch thread (e.g. recompiling the snd_hda_intel driver with #define AZX_MAX_CODECS 4) but this did *not* solve the problem. Any suggestions would be appreciated. I need my music back! -- <a href="http://www.catb.org/~esr/">Eric S.

[alsa-devel] [BUG] New Kernel Bugs
by Natalie Protasevich 19 Nov '07

19 Nov '07

This is the listing of the open bugs that are relatively new, around 2.6.22 and up. They are vaguely classified by specific area. (not a full list, there are more :) The good part is that reporters of the bugs below are still around and haven't dissipated, or disposed of their hardware, so it is a good time to get the bugs. Those bugzillas that have been started as regressions on Rafael's list are not mentioned here so far, since they are being tracked as new regressions already. It would be appreciated if the corresponding maintenance team could take a look, close off any which are fixed and see if they can fix any which aren't. NOTE: when replying to this email, please add the bug number to the Subject in the form [Bug 1234] so that bugzilla will capture the discussion. Thanks.

[alsa-devel] Can this be a driver problem? Sound works fine for ogg files but not for avi
by alsa-devel.20.pris＠spamgourmet.com 18 Nov '07

18 Nov '07

Hello, as I have already reported I'm having problems with my sound: http://news.gmane.org/find-root.php?group=gmane.linux.alsa.devel&article=49… Takashi Iwai suggested installing the latest version of the driver. But, before I do this I want to make sure that it is a driver problem and not some other problem. The thing is, on my system(Ubuntu Gutsy Gibbon) I get perfect sound playing the example ogg files that come with the system. The system sounds seem to work fine also. But I have problems when trying to listen to avi or mp3 files. Can this still be an Alsa problem or is this a problem of some incorrect configuration? Thanks!

[alsa-devel] E-mu 1212M/1820M/1616M development
by Ctirad Fertr 18 Nov '07

18 Nov '07

Hello, I just bought an 1616M PCMCIA in addition to my old 1212m v1 and want to help improve the current driver. I wrote one little patch for those cards in the past (and some bigger patches for my experiments which were never released) and now I have some time to continue. I'm going to add missing switches into mixer, make some changes in mixer to match the real I/O setup of each particular card model and perhaps also write some graphics patchmix like app. Unfortunatelly, I'm unable to fix the most important bugs (at least from my point of view) dua to lack of documentation and knowlenge of DSP programming. These are: 1. non working 24bit playback. It should be on device 0,2 This device exists, but cannot be openned for playback.It is the last thing needed for serious DAW. 2. Non working S/PDIF (and probably ADAT, too) on 1616(M) microdock ports. I think tese ports uses different set of registers than PCI 1010 host card. Am I right? 3. Midi I/O works well on 1212m v1, but only when 48kHz is set. At 44.1kHz signalling is corrupted (different UART timing? How to fix it?). On 1616m microdock MIDI I/O does not work at all. I welcome any comments, advices and patches ;) ---- Ctirad

[alsa-devel] [CONF] All C-Media Codecs based 5.1 Channel USB- Headsets
by thomas schorpp 18 Nov '07

18 Nov '07

Report to devlist as requested from USB-Audio.conf header: 1. all this headsets with windriver inf files + manual showing c-media driver must have the cm106x series 7.1 channel usb-codec in. there's no other from c-media for the design of 5.1 channel usb headsets available at this time, see: http://www.cmedia.com.tw/?q=en/usb_audio 2. the headset interface shows up with 8 channels in lsusb -v , 1 8-ch pcm in /proc, and must be driven with surround7.1 pcm plug instead of surround5.1 or it will not work. speaker-test program works with -c6 -Dsurround7.1, test with -c8 works too, but shows that no SideL/R -speakers connected/routed/downmixed ( Speedlink Medusa 5.1 Mobile USB Headset, cm106L) 3. it works instantly without extra config using programs that allow specifying (-D)surround7.1 like VDR and MPlayer, VLC did not so far (maybe can do with special commandline) and therere maybe other unconfigurable (or buggy?) players that need a missing extra cm106 CARD configfile showing those apps a 5.1 channel device instead a 7.1. i've done none so far, the config file language (especially routing and mappings) is not well documented, sorry. y tom

[alsa-devel] Is there a function I can call from my ISR to tell ALSA to abort playback?

In my ISR, I call snd_pcm_period_elapsed() to tell it that a period has elapsed. I can also detect if playback has aborted for some reason (e.g. DMA controller has died). Is there a function I can call in my ISR to tell ALSA to abort playback or capture? -- Timur Tabi Linux kernel developer at Freescale

[alsa-devel] [PATCH] HDA-Intel - Add support for RV610/RV630 HDMI audio
by Herton Ronaldo Krzesinski 16 Nov '07

16 Nov '07

The Audio interface on HD2400/HD2600 cards isn't currently detected by snd-hda-intel. I added missing pci device ids for RV610 and RV630, but I only had a HD2400 pro card to test, where now the audio interface is detected (and no need to change patch_atihdmi.c, as the codec vendor id remains 0x1002aa01 for which we already have an entry there). I also couldn't test if sound pass-trough is ok (and I don't know how to), but at least now the device is detected.

[alsa-devel] alsa-lib module path question
by Ben C 16 Nov '07

16 Nov '07

Hello, I've written an ALSA external PCM plugin for a client's embedded device. During the client's compilation of alsa-lib (which I have no control over), they did not specify where the module directory should be at. In fact, they're using 1.0.13 where there isn't a configure option to specify the module directory (this was added 1.0.14?). Since this is an embedded project, due to cross compilation, alsa-lib is currently looking at some host directory that does not exist on the target to search for the libasound_module_pcm_xxx.so files. What's worse is that seems like it is dependent on where the client decides to build the RFS (say from /home/joe/project/xxx, but then later /home/bill/project/yyy) -- the alsa-lib module directory could change. For now I've manually created the non-existent host directory on the target and dropped a symbolic link there. But since that could change should they decide to rebuild the RFS, that's not even a viable bad hack solution. Is there any environment variable, configuration option or some other methods where this could be overwritten at runtime?

Virtual Folders. I use VM mode in EMACS, but I believe some other mail readers have the same functionality. I have a virtual folder called "nfs" which shows me all mail in my inbox which has the string 'nfs' or 'lockd' in a To, Cc, or Subject field. When I visit that folder, I see all mail about nfs, whether it was sent to me personally, or to a relevant list, or to lkml. Admittedly if someone doesn't bother to choose a meaningful Subject, then I might miss that. I think this mostly happens when Andrew sends a "-mm" announcement, asked people to change the subject line when following up, and someone follows up without changing the subject line and say "NFS doesn't work any more". I have another virtual folder which matches "md" and "raid" and "mdadm" in any header (so when the people from coraid.com talk about ATA over Ethernet, that gets badly filed, but it is a small cost). Then I have the "bkernel" (boring kernel) folder for all mail from lkml that doesn't mention nfs or raid or md, and isn't from or to me. That folder I skim every week or so and just read the juicy debates and look for interesting tidbits from interesting people - then delete the whole folder, mostly unread. I don't think I could cope with mail without virtual folders. NeilBrown

[alsa-devel] Removal of indirect access in control API
by Takashi Iwai 15 Nov '07

15 Nov '07

Hi, ALSA control elements have "indirect" flag, which is supposed to allow the indirect access via pointer. But, as far as I know, this feature has never been used nor implemented, and unsupported via 32/64bit compat layer. So, I'd like to get rid of this now. The clean-up patch is below. If you have objections, please let me know. thanks, Takashi --- diff -r 34e3c66d7a5c core/control.c --- a/core/control.c Mon Nov 12 18:04:54 2007 +0100 +++ b/core/control.c Mon Nov 12 18:05:16 2007 +0100 @@ -232,8 +232,6 @@ struct snd_kcontrol *snd_ctl_new1(const access = ncontrol->access == 0 ?

[alsa-devel] interrupting snd_pcm_writei or snd_pcm_drain?
by Mike Gorse 15 Nov '07

15 Nov '07

I've noticed that it is unsafe to call snd_pcm_writei or snd_pcm_drain in a pthread with its cancelation type set to asynchronous. snd_pcm_dmix_sync_area can lower a semaphore, and, if the thread is canceled while the semaphore is down, then a subsequent call to the sound device (calling snd_pcm_close, for instance) will also lower the semaphore and cause deadlock. Is this a known issue, and is there a way around it other than to always use deferred cancelation when calling these functions? Thanks, -Mike G-

That sounds overly hash, and the rest of you mail sounds much more moderate and sensible - I can only assume you were using hyperbole?? Putting the "onus on the reporter" is simply not going to work unless you have a business relationship. In the community, we are all volunteering our time (well, maybe my employer is volunteering my time to do community support, but the effect is the same). I would hope that the focus of developers is to empower bug reporters to provide further information (and as has been said, "git bisect" is a great empowerer). Some people will be incredibly help, especially if you ask politely and say thankyou. Others won't for any of a number of reasons - and maybe that means their bug won't get fixed. To my eyes, the "only method that scales" is investing effort in encouraging and training bug reporters. Some of that effort might not produce results, but when others among those you have encouraged start answering the newbee questions on the list and save you the time, you get a distinct feeling that it was all worth while. I think we are in agreement - I just wanted to take issue with that one sentence :-) The rest is great.

[alsa-devel] params_buffer_size() and params_period_bytes() are returning the same value
by Timur Tabi 14 Nov '07

14 Nov '07

I have an ASOC v1 driver that I'm wrapping up. I've noticed something weird in my hw_params() function. I have this code: size_t buffer_size = params_buffer_size(hw_params); size_t period_size = params_period_bytes(hw_params); printk(KERN_INFO "%s: buffer_size=%x period_size=%x\n", __FUNCTION__, buffer_size, period_size); printk(KERN_INFO "%s: params_periods=%u\n", __FUNCTION__, params_periods(hw_params)); And it produces this output: fsl_dma_hw_params: buffer_size=5dc0 period_size=5dc0 fsl_dma_hw_params: params_periods=4 Why am I getting the same value for buffer_size and period_size? buffer_size should be four times period_size. -- Timur Tabi Linux kernel developer at Freescale

The driver really has 3 lines with 80 chars warning, but they are less then 82 char. It's in the codec interconnection map for DAPM.

[alsa-devel] Query regarding snd_pcm_lib_preallocate_pages_for_all()
by Pharaoh . 14 Nov '07

14 Nov '07

Hi, I am trying to use snd_pcm_lib_preallocate_pages_for_all() on an arm based platform for preallocating the DMA buffer. I am using it as snd_pcm_lib_preallocate_pages_for_all(pcm, SNDRV_DMA_TYPE_DEV, NULL, 64 * 1024, 64 * 1024); since I dont know what should be passed as the 3'rd param. I tried passing my device pointer i.e. card->dev after correctly populating it but I get an error as 'DMA coherent mask in not set' and buffer is not allocated. If I pass NULL as shown above, which I think is appropriate, the allocation is done well and I can play some samples too using aplay, but when I do a rmmod all hell breaks free. I am thinking this is corrupting memory some where, since when I preallocate using SNDRV_DMA_TYPE_CONTINUOUS, everything works well but I since I need to mmap the buffer I dont use it. I get following: c001f7e0 c001f7e0 c001f814 c03b3040 0000000b c34c1c98 c34c1c88 1c80: c003642c c0071978 c34c0000 c34c1cb8 c34c1c9c c003b780 c00363fc c34c0000 1ca0: c34c0000 c03b3040 00000001 c34c1cd4 c34c1cbc c003bd94 c003b690 c34c1ce8 1cc0: 60000093 00000001 c34c1ce8 c34c1cd8 c002908c c003bbe8 bf000000 c34c1d08 1ce0: c34c1cec c002b2ac c0028d84 ffffffec c03b3040 c34733c8 c001f7e0 c34c1d40 1d00: c34c1d0c c002b588 c002b250 c03a7060 c34c1d94 00000017 ffffffff c026dd40 1d20: 00000017 c34c1dec 00000004 00000093 40130000 c34c1de8 c34c1d44 c002b688 1d40: c002b3a0 0000007e 00000000 00000000 00000000 00000000 00000000 00000000 1d60: 00000000 c03a7060 c34c1e14 c03b3040 c022eef4 c34c1f14 00000000 00000a00 1d80: c34c1e80 c34c1d90 c019ee84 c01bb390 00000000 7a035438 00000005 00000000 1da0: 00000a00 c03a7060 c0271cdc c34c1d50 00000000 c34c1e08 c34c1dc4 c0063a94 1dc0: c0063984 00000044 ffffffff c34c1e20 00000000 c02eabe0 c347317c c34c1e44 1de0: c34c1dec c00249a0 c002b65c c02eabe0 00000000 00000013 00000093 c34c0000 1e00: c0306200 00000000 c02eabe0 c347317c c001f7e0 40130000 c34c1e44 c02eabe0 1e20: c34c1e34 c02c0bfc c0067478 00000093 ffffffff 10d5f0ff c34c1e7c c34c1e48 1e40: c006d658 c0067444 c3541cc0 00000000 00000002 11b100df 000004c0 c347317c 1e60: c34c0000 00000001 c001f7e0 40130000 c34c1ecc c34c1e80 c006e61c c006d1b8 1e80: c3545000 c001f820 11b100df 0000007e 00000000 00000010 c3545000 00000800 1ea0: c34c0000 ffffffeb c03b3040 c347317c c001f7e0 c001f814 c34c1fb0 40130958 1ec0: c34c1f04 c34c1ed0 c002b470 c006dedc c004822c c03b307c 0000081f ffffffff 1ee0: c026ddc0 0000081f c34c1fb0 40130958 00000055 4012f000 c34c1fac c34c1f08 1f00: c002b688 c002b3a0 c34c1f14 c0222148 c0221a50 c34c1e94 0000000c c34c1e84 1f20: 00000001 00000000 00000000 c1b01040 00000000 00000009 0001d2b4 00000066 1f40: c0024fe4 00000001 c34c1f6c c34c1f58 c01a02c0 c01a01c0 00000000 00000000 1f60: c34c1fa4 c34c1f70 c01a09d0 c01a02b0 c34c1e70 c34c1e74 00000004 0001d2b4 1f80: 00000a00 00000000 0000008e ffffffff 00000115 0001d2dd 00000000 00000000 1fa0: 00000000 c34c1fb0 c0024de8 c002b65c 00000000 0000b05c 54434100 00000001 1fc0: 40130958 00000115 0001d2dd 00000000 00000000 00000055 4012f000 00000007 1fe0: 0001d150 be8ba5ec 0000b05c 40082fbc 60000010 ffffffff 00000000 00000000 Backtrace: [<c0073880>] (page_remove_rmap+0x0/0x118) from [<c006c628>] (unmap_vmas+0x3c4/0x60c) r4 = C02EABE0 [<c006c264>] (unmap_vmas+0x0/0x60c) from [<c00719e8>] (exit_mmap+0x80/0x150) [<c0071968>] (exit_mmap+0x0/0x150) from [<c003642c>] (mmput+0x40/0xe4) r8 = 0000000B r7 = C03B3040 r6 = C001F814 r5 = C001F7E0 r4 = C001F7E0 [<c00363ec>] (mmput+0x0/0xe4) from [<c003b780>] (exit_mm+0x100/0x10c) r4 = C34C0000 [<c003b680>] (exit_mm+0x0/0x10c) from [<c003bd94>] (do_exit+0x1bc/0x9c4) r7 = 00000001 r6 = C03B3040 r5 = C34C0000 r4 = C34C0000 [<c003bbd8>] (do_exit+0x0/0x9c4) from [<c002908c>] (die+0x318/0x36c) [<c0028d74>] (die+0x0/0x36c) from [<c002b2ac>] (__do_kernel_fault+0x6c/0x7c) [<c002b240>] (__do_kernel_fault+0x0/0x7c) from [<c002b588>] (do_page_fault+0x1f8/0x210) r7 = C001F7E0 r6 = C34733C8 r5 = C03B3040 r4 = FFFFFFEC [<c002b390>] (do_page_fault+0x0/0x210) from [<c002b688>] (do_DataAbort+0x3c/0xa0) [<c002b64c>] (do_DataAbort+0x0/0xa0) from [<c00249a0>] (__dabt_svc+0x40/0x60) r8 = C347317C r7 = C02EABE0 r6 = 00000000 r5 = C34C1E20 r4 = FFFFFFFF [<c0067434>] (lru_cache_add_active+0x0/0xa0) from [<c006d658>] (do_wp_page+0x4b0/0x574) r4 = 10D5F0FF [<c006d1a8>] (do_wp_page+0x0/0x574) from [<c006e61c>] (__handle_mm_fault+0x750/0x824) [<c006decc>] (__handle_mm_fault+0x0/0x824) from [<c002b470>] (do_page_fault+0xe0/0x210) [<c002b390>] (do_page_fault+0x0/0x210) from [<c002b688>] (do_DataAbort+0x3c/0xa0) [<c002b64c>] (do_DataAbort+0x0/0xa0) from [<c0024de8>] (ret_from_exception+0x0/0x10) r8 = 00000000 r7 = 00000000 r6 = 0001D2DD r5 = 00000115 r4 = FFFFFFFF Code: e3130901 e1a03004 1594300c e59f008c (e5931004) <1>Fixing recursive fault but reboot is needed!

Re: [alsa-devel] [Pkg-alsa-devel] Bug#450805: alsa-tools-gui: hdspmixer initializes only first Hammerfall DSP card
by Elimar Riesebieter 14 Nov '07

14 Nov '07

forwarded 450805 alsa-devel(a)alsa-project.org tags 450805 pending patch Thanks Hi ALSA developers, does it make sense to apply the patch to HEAD? I don't have a Hammerfall handy and can not test it. Thanks for cooperation. Elimar On Sun, 11 Nov 2007 the mental interface of Frank Heckenbach told: Package: alsa-tools-gui Version: 1.0.13-1 Severity: normal Tags: patch We are using Hammerfall DSP cards. After booting, their audio output remains silent until hdspmixer is started. No interaction in the GUI of hdspmixer is necessary to unmute the first HDSP card; however, further cards are only unmuted when activating the respective GUI page ("2", "3"). Apparently, hdspmixer does some automatic initialization of the card when activating the page. Since we'd like to have a fully automatic startup, the following patch activates the page for each existing card on startup, thereby initializing them. There are surely more elegant solutions, but this patch is tested and solves the problem for us. --- alsa-tools-1.0.13/hdspmixer/src/HDSPMixerCardSelector.h.orig 2007-04-16 19:49:22.000000000 +0200 +++ alsa-tools-1.0.13/hdspmixer/src/HDSPMixerCardSelector.h 2007-04-16 19:50:51.000000000 +0200 @@ -37,6 +37,7 @@ int card; HDSPMixerWindow *basew; HDSPMixerCardSelector(int x, int y, int w, int h, int card); + void ActivateCard (int i); void draw(); int handle(int e); }; --- alsa-tools-1.0.13/hdspmixer/src/HDSPMixerCardSelector.cxx.orig 2007-04-16 19:49:23.000000000 +0200 +++ alsa-tools-1.0.13/hdspmixer/src/HDSPMixerCardSelector.cxx 2007-04-16 19:53:45.000000000 +0200 @@ -45,27 +45,25 @@ } } +void HDSPMixerCardSelector::ActivateCard (int i) +{ + card = i + 1; + basew->current_card = i; + basew->cards[i]->setMode (basew->cards[i]->getSpeed ()); + redraw (); +} + int HDSPMixerCardSelector::handle(int e) { int xpos = Fl::event_x()-x(); switch (e) { case FL_PUSH: - if (xpos < 13 && card != 1) { - card = 1; - basew->current_card = 0; - basew->cards[0]->setMode(basew->cards[0]->getSpeed()); - redraw(); - } else if (xpos >= 24 && xpos < 37 && card != 2 && basew->cards[1] != NULL) { - card = 2; - basew->current_card = 1; - basew->cards[1]->setMode(basew->cards[1]->getSpeed()); - redraw(); - } else if (xpos >= 48 && card != 3 && basew->cards[2] != NULL) { - card = 3; - basew->current_card = 2; - basew->cards[2]->setMode(basew->cards[2]->getSpeed()); - redraw(); - } + if (xpos < 13 && card != 1) + ActivateCard (0); + else if (xpos >= 24 && xpos < 37 && card != 2 && basew->cards[1] != NULL) + ActivateCard (1); + else if (xpos >= 48 && card != 3 && basew->cards[2] != NULL) + ActivateCard (2); return 1; default: return Fl_Widget::handle(e); --- alsa-tools-1.0.13/hdspmixer/src/HDSPMixerWindow.cxx.orig 2007-04-16 19:41:21.000000000 +0200 +++ alsa-tools-1.0.13/hdspmixer/src/HDSPMixerWindow.cxx 2007-04-16 19:55:13.000000000 +0200 @@ -700,6 +701,9 @@ Fl::atclose = atclose_cb; Fl::add_handler(handler_cb); Fl::add_timeout(0.030, readregisters_cb, this); + i = 0; + while (cards[i] != NULL) + inputs->buttons->cardselector->ActivateCard (i++); } int HDSPMixerWindow::handle(int e) -- Experience is something you don't get until just after you need it!

Hello, Where is the ALSA mixer API documentation? I looked at http://www.alsa-project.org/alsa-doc/alsa-lib/mixer.html, but that only says "Mixer interface is designed to access the abstracted mixer controls. This is an abstraction layer over the hcontrol layer". ttfn/rjk

[alsa-devel] Intel HD Audio
by Chris Pemberton 13 Nov '07

13 Nov '07

I've been trying to fix audio on my Lenovo 3000 N100 laptop for quite some time; on this list and via bug #0003468. I finally got tired of the xorg graphics woes and hacking for sound, so I am now "temporarily" running Vista. I'd like to get this audio fixed permanently, so if you need any details from the working Vista drivers, let me know before I get sick of Windows and switch back to Linux. Chris

[alsa-devel] New developer question
by Pete Fawcett 13 Nov '07

13 Nov '07

Dear Alsa Developers I am trying to find out how to submit some fixes to ALSA drivers. All I could find on the web site was to subscribe to this mailing list so I hope this is the correct place to raise this. I have made some changes to the driver for AD1988 device. This is an HDA device and handled by the snd_hda_intel module. The specific hardware is handled by patch_analog.c I have made some changes so that 5.1 surround sound is now output on my motherboard. Previously stereo sound was output to all all three pairs of speakers. That's all fine for me, but in the spirit of open source I thought I should submit these changes for wider use. Please advise me how I proceed from here. Thanks Pete
