Bugzilla – Bug 113603
sounds crash after some times
Last modified: 2007-02-19 14:37:52 UTC
When watching movies (KDE, Kaffeine), sound disappears at about 20 minutes. All the system can't play a sound, so I must restart the computer to have sound. Sometimes I should restart many times before to recover (8 time yesterday !). My laptop is an Asus A6G and lspci -vv gives : 0000:00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 03) Subsystem: ASUSTeK Computer Inc.: Unknown device 1893 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 0 Interrupt: pin B routed to IRQ 6 Region 0: I/O ports at e000 [size=256] Region 1: I/O ports at e100 [size=64] Region 2: Memory at 40000400 (32-bit, non-prefetchable) [size=512] Region 3: Memory at 40000600 (32-bit, non-prefetchable) [size=256] Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=375mA PME(D0+,D1-,D2-,D3hot+,D3cold+) Status: D0 PME-Enable- DSel=0 DScale=0 PME-
If a rebooting doesn't help, it sounds like a hardware problem...
Or a driver problem ? Reboot works in a majority of case. But sometimes sound works at start ant cuts just after. This bug doesn't exist when I waork on windows or mandriva. Some ideas : - problem whith "saving energy" module. - problem with computer too warm. Is there a log for sound card ?
Well, it depends on what "can't play" means. If it's related with DMA, i.e. a hardware problem or something very deep in kernel, the interrupt won't be increased when the sound "stops". You can see the interrupt counts in /proc/interrupts. If it's a mixer problem, you can check the mixer status when it happens, simply by running alsamixer (or get a snapshot via "alsactl -f foo store"). If it's a problem with dmix plugin of alsa-lib, you don't need to reboot the machine, but just stopping all apps accessing the sound should fix. You can see processes via "fuser /dev/snd/pcmC0D0*". No, there is no log unless a fatal problem is detected on kernel. Anyway, if this happens, try to play another file via aplay, e.g. "aplay -vv somefile.wav".
In beta 4, I have no sound at all. And KDE gives me this log when I clik on "test sound" in KDE config : (no debugging symbols found) Using host libthread_db library "/lib/tls/libthread_db.so.1".

Answer to comment 3 : I join the file "interrupts" and the result of "aplay". For "alsactl -f foo store", nothing happens. For "fuser /dev/snd/pcmC0D0*", I have : "/dev/snd/pcmC0D0p: 9101m 9115m" I hope it can help you.

I've always the same problem in Suse 10 final version. One more thing : when I select ALSA in the KDE's control center, the progress bar loop...
The race of dmix has been already fixed in the recent versions.
