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 - 03-26-06 09:55 ---------------------------------------------------------------------- For au88x0 with stereo codec, instead of using vdownmix plugin 1.0.11rc4 pcm.!surround51 { type vdownmix slave.pcm "default" } you can use multi plugin and hardware mixing, the drawback is 6 sample rate convertors are used AU8810.pcm.surround51.0 { @args [ CARD ] @args.CARD { type string } type multi slaves [ { pcm { @func concat strings [ "cards.AU8810.pcm.front.0:CARD=" $CARD ] } channels 2 } { pcm { @func concat strings [ "cards.AU8810.pcm.front.0:CARD=" $CARD ] } channels 2 } { pcm { @func concat strings [ "cards.AU8810.pcm.front.0:CARD=" $CARD ] } channels 1 } { pcm { @func concat strings [ "cards.AU8810.pcm.front.0:CARD=" $CARD ] } channels 1 } ] bindings [ { slave 0 channel 0 } { slave 0 channel 1 } { slave 1 channel 0 } { slave 1 channel 1 } { slave 2 channel 0 } { slave 3 channel 0 } ] } ---------------------------------------------------------------------- Raymond - 03-29-06 17:48 ---------------------------------------------------------------------- Sorry, there is no need to add the channel parameter 4 to "surround40" device in AU8810.conf or AU8830.conf, the device 0 of au88x0 driver already use the hardware mixer to perform those upmix plugin functions : upmix_1_to_2, upmix_1_to_4, upmix_2_to_4 The upmix plugin use 2 SRC of au88x0 for upmix_1_to_2 and 4 SRC for upmix_1_to_4, but au88x0 only use 1 SRC when using the hardware mixer to perform the upmix. In fact, adding the channel parameter 4 to "surround40" will lead to a more complex "surround51" config using "multi" and hardware mixing to downmix 5.1 to 2.0/4.0 A "rear" device can be implemented using the "subdevice playback volume" as described in https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1835 Issue History Date Modified Username Field Change ====================================================================== 04-12-05 20:43 alien999999999 New Issue 04-12-05 20:43 alien999999999 Distribution => Mandrake 04-12-05 20:43 alien999999999 Kernel Version => 2.6.7 04-12-05 20:48 alien999999999 Note Added: 0004461 04-12-05 20:49 alien999999999 File Added: au88x0.c 04-12-05 20:49 alien999999999 File Added: au88x0.h 04-12-05 20:50 alien999999999 File Added: au88x0_core.c 04-12-05 20:50 alien999999999 File Added: au88x0_mixer.c 04-12-05 20:51 alien999999999 Note Added: 0004462 08-24-05 11:13 Raymond Note Added: 0005928 10-27-05 02:27 Raymond Note Added: 0006564 01-03-06 04:04 Raymond Note Added: 0007397 01-04-06 22:08 alien999999999 Note Added: 0007455 01-05-06 07:21 Raymond Note Added: 0007462 01-05-06 20:32 shurick Issue Monitored: shurick 01-06-06 17:17 alien999999999 Note Added: 0007488 01-06-06 17:33 alien999999999 File Added: alsa-cvs-2006-01-04.patch 01-13-06 13:51 Raymond Note Added: 0007639 01-13-06 18:18 tiwai Note Added: 0007648 01-14-06 04:53 Raymond Note Added: 0007653 01-14-06 05:00 Raymond Note Edited: 0007653 01-17-06 12:27 Raymond Note Added: 0007697 01-18-06 15:51 Raymond Note Added: 0007710 01-18-06 15:52 Raymond File Added: au88x0_codec.patch 01-19-06 13:51 Raymond Note Added: 0007719 02-05-06 05:20 Raymond Note Edited: 0007710 02-05-06 05:28 Raymond Note Added: 0007930 02-13-06 16:38 Raymond Note Deleted: 0006564 02-13-06 16:41 Raymond Note Added: 0008054 03-01-06 07:39 Raymond Note Added: 0008273 03-18-06 12:28 Raymond Note Deleted: 0008273 03-20-06 17:54 Raymond File Added: au88x0_conf.patch 03-21-06 02:02 Raymond Note Added: 0008734 03-21-06 18:01 tiwai Note Added: 0008754 03-22-06 02:05 Raymond File Added: au88x0_mpu401.patch 03-22-06 02:28 Raymond Note Added: 0008779 03-22-06 02:31 Raymond Note Edited: 0008779 03-22-06 02:38 rlrevell Note Added: 0008782 03-22-06 04:00 Raymond Note Added: 0008836 03-22-06 04:09 rlrevell Note Added: 0008839 03-26-06 09:55 Raymond Note Added: 0008967 03-29-06 17:48 Raymond Note Added: 0008995 ====================================================================== ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
