The front and rear channels (Surround40) always swapped afterward using speaker-test or xine. Playing stereo sound is OK. speaker-test -c4 -D hw:0,0 speaker-test 1.0.11rc2 Playback device is hw:0,0 Stream parameters are 48000Hz, S16_LE, 4 channels Using 16 octaves of pink noise Rate set to 48000Hz (requested 48000Hz) Buffer size range from 2 to 8192 Period size range from 1 to 512 Periods = 4 Buffer time size 2525 To choose buffer_size = 8192 To choose period_size = 2048 was set period_size = 512 was set buffer_size = 8192 0 - Front Left 1 - Front Right 3 - Rear Right 2 - Rear Left Time per period = 11.856821 0 - Front Left 1 - Front Right 3 - Rear Right 2 - Rear Left ====================================================================== ---------------------------------------------------------------------- ponchick - 02-17-06 03:35 ---------------------------------------------------------------------- I try aplay and cannot reproduce channel swapping. I think this doesn't mean that bug is just in speaker-test. When I run speaker-test I interrupt it with ^C. At this moment driver can be in some state that leads to swapping channels on next run. I believe this bugs could be closed. If someone can reproduce "random" channel swapping in app other then speaker-test there should be separate bugreport. About resource exhausting - I post complete logs. Before is just initializing logs, similar to ACPI: PCI Interrupt 0000:04:01.0[A] -> GSI 19 (level, low) -> IRQ 225 Vortex: init.... <6>done. Only interrupts and PCI address are differ. If you want more research I think you should open new bug. P.S. If you think that I should test another issues with au88x0 cards you can mail me to lkabanov at mail dot ru. ---------------------------------------------------------------------- Raymond - 02-17-06 04:28 ---------------------------------------------------------------------- Steps to reproduce the problem with alsa-1.0.11rc3 for au8830 (STAC9708) 1) use alsamixer to turn "Sigmatel Surround Playback Switch" off, it mix the front and rear channels numid=19,iface=MIXER,name='Sigmatel Surround Playback Switch' ; type=BOOLEAN,access=rw---,values=1 : values=off 2) aplay -D hw:0,0 out1lq.wav ( you should hear the sound only from left speaker of out1 at first run ) 3) aplay -D hw:0,0 out1lq.wav ( Do the sound come out from left speaker of out2 with alsa-1.0.11rc3 on second run? ) There may be some difference in MX300, since Win9x can detect one/two jacks are plugged into out1 and out2 using GPIO Issue History Date Modified Username Field Change ====================================================================== 01-08-06 17:41 Raymond New Issue 01-08-06 17:41 Raymond Distribution => Fedora Core 1 01-08-06 17:41 Raymond Kernel Version => 2.4.22-1.2199.nptl 01-27-06 16:45 Raymond File Added: au88x0_surround40.patch 02-04-06 06:26 Raymond Note Added: 0007912 02-10-06 05:36 ponchick Note Added: 0007987 02-10-06 06:32 Raymond Note Added: 0007991 02-10-06 10:50 ponchick Note Added: 0007998 02-10-06 11:25 Raymond Note Added: 0008000 02-10-06 13:49 Raymond Note Added: 0008003 02-10-06 13:56 Raymond Note Edited: 0008003 02-12-06 07:48 Raymond Note Edited: 0008003 02-12-06 10:12 Raymond Note Edited: 0008000 02-16-06 05:37 ponchick Note Added: 0008085 02-16-06 08:12 Raymond Note Added: 0008088 02-16-06 10:12 Raymond Note Added: 0008090 02-16-06 10:28 Raymond Note Edited: 0008090 02-16-06 16:07 Raymond Note Added: 0008097 02-17-06 03:35 ponchick Note Added: 0008104 02-17-06 04:28 Raymond Note Added: 0008105 ====================================================================== ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
