[alsa-devel] [PATCH] ALSA: Fix declaration of sound_class
by Mark Brown 15 Dec '08

15 Dec '08

Include sound/core.h in sound_core.c so that sound_class is declared before it is defined, avoiding it looking like it should be static.

[alsa-devel] Xrun stack trace for 1010LT
by Pete cat 15 Dec '08

15 Dec '08

Im trying to get xrun free recording from a pair of 1010LTs (ice1712) and ive resorted to setting xrun_debug to record stack traces on xruns. Im getting xruns every few minutes (between 2 and 15 minute gaps between single xrun events) and every xrun produces identical stack traces like this: [17127.486287] Pid: 775, comm: IRQ-3 Not tainted 2.6.24.1 #2 [17127.486309] [<c02ade37>] snd_pcm_period_elapsed+0x247/0x2f0 [17127.486325] [<c010312e>] __switch_to+0x9e/0x150 [17127.486336] [<c0128674>] finish_task_switch+0x34/0xd0 [17127.486350] [<c02c2119>] snd_ice1712_interrupt+0xa9/0x1a0 [17127.486364] [<c016ab7c>] handle_IRQ_event+0x5c/0x100 [17127.486379] [<c016b1ba>] thread_simple_irq+0x4a/0x90 [17127.486390] [<c016bb09>] do_irqd+0x229/0x290 [17127.486404] [<c016b8e0>] do_irqd+0x0/0x290 [17127.486411] [<c0141ef2>] kthread+0x42/0x70 [17127.486418] [<c0141eb0>] kthread+0x0/0x70 [17127.486425] [<c0105857>] kernel_thread_helper+0x7/0x10 [17127.486437] ======================= Running the rt kernel (Linux ubuntu-studio 2.6.24.1 #2 SMP PREEMPT RT Thu Dec 4 21:30:26 GMT 2008 i686 GNU/Linux) - although the original installation was Ubuntu studio, the kernel is recompiled. The xruns seem to be all on the same card. IRQs are set to priority of 99 with chrt. Software for record is arecord, modified to use a 10 second ring buffer which is written to disk in a separate thread. I was hoping that from the stack trace I could work out what was causing the xruns, but from the above it dosent look like there is anything causing them. However this is the first time I am using stack traces so maybe im missing something. Can anyone point to the fault for me? Thanks, Pete

[alsa-devel] Intel 82801I (ICH9 Family) HD Audio Controller on a HP dv4 computer
by Jean-Pierre ANDRE 15 Dec '08

15 Dec '08

Hi, I am getting difficulty setting up ALSA for my new HP portable computer. lspci displays the audio chip as : Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03) and /proc/asound displays the codec as IDT 92HD71B7X I have uploaded the detailed hardware and configuration parameters to http://pagesperso-orange.fr/b.andre/visits.html/92HD71B7X I am using Fedora 10 x86_64 without pulseaudio and with the latest alsa-driver : alsa-driver-1.0.18a.16.g4012f.139.g6e583.tar.bz2 I have googled for a similar problem, but did not get to an actual fix, the following thread appears to deal with a most similar situation : http://forums.opensuse.org/pre-release-beta/399731-beta-5-no-sound.html After several tries, I have set modprobe.conf as alias snd-card-0 snd-hda-intel options sound slots=snd-hda-intel options snd-hda-intel model=hp-m4 single_cmd=1 enable_msi=1 Results : aplay freezes, with some sound output which is the continual repeat of the initial expected sound (some fraction of a second repeated). However if I boot with pci=noacpi the output is correct (I do not understand the relation of power management to sound, there must be one as I see : HDA Intel 0000:00:1b.0: power state changed by ACPI to D0 when I unload/reload alsa) WITHOUT the pci=noacpi option : - mplayer outputs the sound correctly (does mplayer bypass alsa ?) - xine outputs a chopped sound (some 100ms OK, some 100ms silent, some 100ms OK, etc, with a period which could be 200..500ms) - most players (eg Real player) just freeze. I would say that when some sound buffer gets empty, the driver does not get the information, so it does not fill the buffer again. I have done some digging into the code. I see that this 92HD71B7X chip is supported for HP dv5 and dv7 computers (subsystem ID 103c30f2 and 103C30f4), but mine is a HP dv4 showing a subsystem ID 103c30f7, so it must be somewhat different and not supported yet. Can anybody suggest some fix ? If needed I can apply patches to the code and do some testing so that my configuration gets supported in subsequent versions. Regards Jean-Pierre

Which I/O are you referring to? The headphone output seems unplugged, and thus the outputs are only from other line-outs, as far as I see the codec info. Takashi

[alsa-devel] Latest snapshot - reliable source?
by Klaus Schulz 15 Dec '08

15 Dec '08

Hello Takashi. Can I regard your ftp link below as a kind of reliable source where to get the latest snapshot at any time? Can I also expect that it is compatible to latest official driver release? Because than I'd ask people in (worst) case of trouble to give it a try before spamming the mailing list. ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-sna… THX \Klaus

by Paulo Cavalcanti 15 Dec '08

15 Dec '08

Hi, alsa driver 1.0.18 has been a nightmare for me. I had a perfectly working sound for my Intel D975XBX2 when using alsa driver 1.017. Going to 1.0.18 just muted my front sound. Well, maybe not everybody needs a front sound output, but I just stick with the 1.01.17 driver. Then, I -- Paulo Roma Cavalcanti LCG - UFRJ

[alsa-devel] Bugs on aspire one A150
by Maxim Levitsky 13 Dec '08

13 Dec '08

I have just bought an Aspire one A150, XP version, as it was the only available here, and installed ubuntu on it. Bugs I discovered so far: ** 1 - embedded controler works in polling mode, due to this: [ 0.708571] ACPI: EC: non-query interrupt received, switching to interrupt mode [ 1.224043] ACPI: EC: missing confirmations, switch off interrupt mode. Maybe this is the reason for the fact that gnome power manager freezes when I unplug the AC, and freezes often when I try to see battery status. (Note: same is seen on my acer aspire 5720) ** 2 - wireless: not to mention the fact that ath5k wasn't installed by default in ubuntu... wireless more or less works, but kernel log is full of backtraces. Was able to connect to my WPA2 access point. Sometimes wireless fails completely, especially after suspend to ram. Advanced features like monitor/injection work, but when I changed the card's mac address it stopped working. I also noticed that if I then start airodump, then wireless works with new mac. ** 3 - internal mic doesn't work. tried model=acer, model=auto. Overall it seems that alsa misprograms O/B realteck codec. I talk about this later. Have same issue on my acer 5720 ** 4 - wireless led doesn't work. ath5k devs, can you fix this? ** 5 - coretemp doesn't show cpu temperature, I have seen somewhere that atom support same thermal diode as core2 and only patch to detect it is needed. Please include such path in 2.6.28 if exists. ** 6 - both card readers are missing from lspci, is this normal? ** 7 - opengl is broken, I tried running neverball in fullscreen, but it shows wrong/corrupted textures (compiz is running, and working well thought) Now I installed 2.6.28-rc3 (actually latest -git) Sadly nothing improved. I only found few regressions: * Wireless now drops connection from my WPA2 access point after few minutes. I changed temporarily its wireless protection to WEP and open mode, and both work fine, maybe this is related to periodic key exchange WPA does? * System doesn't reboot/shutdown, just hangs. Best regards, Maxim Levitsky.
