Dear All: Is there any futher action to this topic "BF537Stamp Linphone audio falling behind". the URL is http://blackfin.uclinux.org/gf/project/uclinux-dist/forum/? action=ForumBrowse&forum_id=39&_forum_action=ForumMessageBrowse&thread_id=22524 we have the same problem, but if we switch to alsa lib interface. the problem seems gone. Thanks in advance. Best Regards, Akio

[alsa-devel] Asus M2NPV-VM (AD1986A) - Surround does work, snd-hda-intel dies on volume change
by Ma Begaj 28 Sep '07

28 Sep '07

Hi, Sorry if this email is not for devel mailing list, but this sounds to me like a bug or development problem. If I am wrong, I will post it on the user list. And for the long email ... I just wanted to describe everything I tried. I found a lot of messages about problems with sound chip AD1986A on motherboard Asus M2NPV-VM. It is almost always the same problem, surround does not work and sound mutes (module dies) when the user change volume. That is my problem too. I found a lot of solutions by using "model=3stack", sometimes with "position_fix=1", but that does not work for all the users. I checked the list, I read dozens of emails, but nothing helped. I found a few patches on the list, but all of them were for kernels < 2.6.22. I used Slackware 12.0 and model=3stack caused a terrible "weeping" sound on the rear left speaker, but the stereo worked. I read a lot of success stories with this motherboard and Ubuntu and after playing whole week long on Slackware (kernel 2.6.21.5 and 2.6.22.6), I decided to try it with Ubuntu Feisty (2.6.20 and 2.6.22.9), although I did not believe that Ubuntu should help. It actually helped partly because the weeping sound disappeared, but I had only stereo. When I changed the "Channel Mode" jack in alsamixer from 2ch to 6ch, sound muted and module died. The only way to get the sound back was to stop playing file, and rmmod/modprobe snd_hda_intel again. Using model=6stack gives me surround sound by using "speaker-test -c6 ..." (nice female voice guessed right every speaker) but module was still dying as soon as I changed volume. Does someone have an idea what to do with this chip ... I am really desperate and beginning to hate this great motherboard ... Thanks a lot. M.

[alsa-devel] Userspace drivers
by Josh Litherland 27 Sep '07

27 Sep '07

Is there any facility for developing an ALSA device driver in userspace? I'm particularly interested in mixer devices; my goal is to expose the Thinkpad hardware volume buttons as an ALSA mixer. Thanks for any pointers! -- Josh Litherland (josh(a)temp123.org)

[alsa-devel] tiwai downtime again
by Takashi Iwai 25 Sep '07

25 Sep '07

Hi, I'll be on vacation for two weeks from today (mostly because of movement to a new apartment, no beach with a cocktail in shiny south islands), so likely will be unresponsive to e-mails during that. If your patches weren't be reviewed/applied, don't hesitate to repost later. Thanks, Takashi

[alsa-devel] snd_hda_intel bug
by Pablo Yaggi 25 Sep '07

25 Sep '07

Please let me know if a bug report must be placed somewhere else because i get no reply about this issue and i don't know if the snd_hda_intel driver maintainer received it. The bug repost: i bought a sony vaio fz19vn, i try both modes for the snd_hda_intel, vaio and vaio-ar, the same problem happen with both of them, when i plugin the headset internal speakers are not muted, so here is the card info: 00:00.0 0600: 8086:2a00 (rev 0c) Subsystem: 104d:9005 Flags: bus master, fast devsel, latency 0 Capabilities: [e0] Vendor Specific Information 00:02.0 0300: 8086:2a02

[alsa-devel] [PATCH] New Aztech Sound Galaxy driver
by Rene Herman 25 Sep '07

25 Sep '07

Hi Takashi. This is a new driver for Aztech Sound Galaxy ISA soundcards based on the AZT1605 and AZT2316 chipsets. It's constructed as two seperate drivers for either chipset generated from the same source file, with (very) minimal ifdeffery. The drivers check the SB DSP version to decide if they are being loaded for the right chip. AZT1605 returns 2.1 by default, and AZT2316 3.1. This isn't full-proof as the DSP version can actually be set through software but it's close enough -- as far as I've been able to see, the DSP version can not be stored in the EEPROM and the cards will therefore startup with the defaults. This distinction could (with the same success rate) also be used to decide which chip we're looking at at runtime meaning a single, merged driver is also an option but I feel it's actually nicer this way. A merged driver would have to postpone translating the passed in resource values to the card configuration until it knew which one it was looking at and would need to postpone erring out on mpu_irq=10 for azt1605 and mpu_irq=3 for azt2316. If you differ, I will merge them, but I'd rather keep them seperate. The drivers have been tested on various cards. For snd-azt1605: FCC-ID I38-MMSN811: Aztech Sound Galaxy Nova 16 Extra FCC-ID I38-MMSN822: Aztech Sound Galaxy Pro 16 II and for snd-azt2316: FCC-ID I38-MMSN824: Aztech Sound Galaxy Pro 16 AB FCC-ID I38-MMSN826: Trust Sound Expert DeLuxe Wave 32 (05201) FCC-ID I38-MMSN830: Trust Sound Expert DeLuxe 16+ (05202) FCC-ID I38-MMSN847: Trust Sound Expert DeLuxe Wave 32-3D (06301) FCC-ID I38-MMSN852: Aztech Sound Galaxy Waverider Pro 32-3D I38-MMSN826 is also known as "Aztech Sound Galaxy Waverider 32+". All cards work fully -- full-duplex PCM, MIDI and FM. Full-duplex is a little flaky on some. I38-MSN811 tends to not work in full duplex, but sometimes does with the highest success rate being achieved when you first start the capture and then a playback instead of the other way around (it's a CS4231-KL codec). The cards with an AD1845XP codec (my I38-MMSN826 and one of my I38-MMSN830s) are also somewhat duplex-challenged. Sometimes full-duplex works, sometimes not and this varies from try to try. This seems likely to be a timing problem somewhere inside cs4231-lib. I38-MMSN826 has an additional "ICS2115 WaveFront" wavetable synth onboard that isn't supported yet. The wavetable synths on I38-MMSN847 and I38-MMSN852 are wired directly to the standard MPU-401 UART and the AUX1 input on the codec and work without problem. CD-ROM audio on the cards is routed to the codec "Line" input, Line-In to its Aux input, and FM/Wavetable to its AUX1 input. I did not rename the controls due to the capture source enumeration: I see that capture-source overrides are hardcoded in cs4231-lib and this is just too ugly to live. Versus the old snd-sgalaxy driver, these drivers add support for the models without a configuration EEPROM (common), full-duplex, MPU-401 UART and OPL3. In the future they should grow support for that ICS2115 WaveFront synth on 826 and an hwdep interface to write to the EEPROM on the models that have one. lib.c was split off in preparation of having snd-azt2320 use it as well and generally containing non soundgalaxy specific code that might at some point make it into an isa/lib.c or something. It's tiny, so it's not constructed as a helper module but simply compiled into both drivers. Signed-off-by: Rene Herman <rene.herman(a)gmail.com> [ all of the above is intended as a changelog ] Given that they are new drivers with new names, they shouldn't disturb anything and can as far as I'm concerned make 1.0.15 but if you feel it's too late (and/or don't want the two seperate drivers), so be it.

[alsa-devel] race conditions in alsa core
by Trent Piepho 24 Sep '07

24 Sep '07

In the process of trying to discover that kind of locking ALSA provides to a driver and what the driver must take care of itself, I think I have found some race conditions inside the alsa core. I think there are likely quite a few, but this example was one of the easiest to prove. ALSA uses unlocked_ioctl, which means ioctl calls aren't protected by the BKL and may run at the same time. Some ioctls, for instance HW_PARAMS, don't appear to have any locking done by ALSA. It's entirely possible for two hw_params calls to run at the same time on the same substream, and the ALSA core (and probably many drivers too) can't handle this. The following patch helps to create a larger window for the race condition, so that it can be triggered consistently. --- a/sound/core/pcm_native.c Tue Sep 04 09:02:06 2007 +0000 +++ b/sound/core/pcm_native.c Sat Sep 22 17:12:37 2007 -0700 @@ -411,6 +411,7 @@ static int snd_pcm_hw_params(struct snd_ runtime->channels = params_channels(params); runtime->rate = params_rate(params); runtime->period_size = params_period_size(params); + { static unsigned long x=1; if(test_and_change_bit(0, &x)) msleep(10); } runtime->periods = params_periods(params); runtime->buffer_size = params_buffer_size(params); runtime->tick_time = params_tick_time(params); This causes every other call to snd_pcm_hw_params() to have a 10ms delay between setting the period size and period count. If there are two calls within 10ms, the period count should come from the first call (which slept), while the period size will be from the second call. My test program will call the HW_PARAMS ioctl twice from different threads running at the same time. The first call will ask for the maximum number of periods with minimum size, the second call for the minimum number of periods of maximum size. When prepare is called, we discover that the runtime is set for the maximum number of periods of maximum size, which exceeds the buffer size. Of course even if it didn't exceed the buffer size, the params should be from one call or the other, not some random combination of both. I've attaching a very simple dummy ALSA driver which shows this. All it does is print timestamps and a few parameters when the various callback functions are invoked. The output looks like this: as_open - 0.084 us as_hw_params - 552.864 us periods 128, period size 1024 as_hw_params - 589.996 us periods 1, period size 131072 as_prepare - 11065.307 us periods 128, period size 131072 as_close - 11278.229 us Notice how in prepare the runtime has parameters that are a combination of the two hw_params calls. This test program should trigger the same race with any other ALSA driver. Just adjust the period count and size. The test program doesn't use the ALSA lib. It does need the headers from the alsa lib package to compile, since this seems to be the only place where user space headers for the device interface are provided.

[alsa-devel] Emux hwdep ioctl requests
by Claudio Matsuoka 24 Sep '07

24 Sep '07

Hi, I'm writing an application for Emux patch loading using asfxload as reference, and noticed that there are many ioctl request definitions specified in the application instead of in a system header file. Should I do the same redefining SNDRV_EMUX_IOCTL_VERSION, SNDRV_EMUX_IOCTL_LOAD_PATCH, etc. or there are plans to place these in a common location? Also it seems that current Ubuntu doesn't have /usr/include/linux/awe_voice.h, has that been deprecated for some reason or it's just a bug in the distro?
