[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?
by Timur Tabi 16 Nov '07

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?
