A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1047> ====================================================================== Reported By: alien999999999 Assigned To: mjander ====================================================================== Project: ALSA - driver Issue ID: 1047 Category: PCI - au88x0 Reproducibility: sometimes Severity: block Priority: normal Status: assigned Distribution: Mandrake Kernel Version: 2.6.7 ====================================================================== Date Submitted: 04-12-2005 20:43 CEST Last Modified: 06-26-2006 14:55 CEST ====================================================================== Summary: module hangs at seemingly random times Description: sometimes i start playing a song, and it starts playing a few second or so and hangs, then i kill the application and modprobe -r all sound modules and modprobe them again to make it work again. BUT: sometimes not only that happens, but also when i try to kill the apps it will not kill. when that happens, all kill, killall, top, ps aux commands hang at the command line and cannot be killed by CTRL-C or otherwise, i have been able to see that when i stopped my display managener I did an lsmod and it gave something like this: snd-pcm-oss 59752 11 snd-mixer-oss 20480 1 snd-pcm-oss snd-au8810 43760 220 snd-ac97-codec 83408 1 snd-au8810 snd-pcm 108172 112 snd-pcm-oss,snd-au8810,snd-ac97-codec snd-page-alloc 10384 1 snd-pcm gameport 3840 1 snd-au8810 snd-mpu401-uart 11904 1 snd-au8810 as you can see the snd-au8810 module seem to have an impossible number of "dependencies" (i think has to do with the number of unclosed sound-apps trying to be played; this could be since gaim is programmed to execute an 'aplay %s') i've had this major crash below only 3 times; and the logs didn't detect anything specific at the time. the only thing the logs mentioned at that time was an ntpd sync going on; so the only thing i can think of is that at a certain moment when a sync is going on, some kind of lock is holding cause this to happen... the only thing that i can do to fix this is reset... it is interesting to note that i also have an snd-emu10k1 as second card, which never gave problems like this, and i am always able to "modprobe -r snd-emu10k1" ... ====================================================================== ---------------------------------------------------------------------- Raymond - 06-26-06 03:05 ---------------------------------------------------------------------- >>I don't know if this is true on any driver, but here's what happend yesterday: >> (i have au8810 driver; on x86_64 system) >> i was watching google video on my system >> (google video is a flash thing; thus emulated and uses OSS (the only app that >> needs it)) and suddenly gaim reconnected a network and beeped using aplay >> (ALSA) as a result, the sound was played, all sound looped (also flash), and a >> few hours later, my /var/log/kernel/warnings was > 600MB (kernel warnings). It seem that you only send the kernel warning to rlrevell. flash open playback/capture stream and use up 4 SRC, do gaim also open capture stream ? For ALSA au88x0 driver, it is possible to run two or more instances of "arecord" or "record" concurrently This is why dsnoop is not needed for au88x0 Most of the ALSA drivers don't support this when using device "hw". Do OSS emulation support this feature ? ---------------------------------------------------------------------- Raymond - 06-26-06 14:55 ---------------------------------------------------------------------- As the hardware resources (e.g. SRC) are limited, under certain condition (e.g. https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2228) it is fatal to let an OSS application (e.g. flash plugin) through OSS emuneration to probe (mono/stereo) (playback/capture) hw_param. During the low resource condition, ALSA applications can be rejected by return error in snd_vortex_pcm_hw_params(). Is this possible for the driver during low resource condition to reject an OSS application by return error in snd_vortex_pcm_open() ?
