http://git.alsa-project.org/?p=alsa-kernel.git&a=search&h=HEAD&st=commit&s=au88x0 There are several patches related to au88x0 but I am not sure that your alsa-driver-1.0.24 contain all those patches 1) Did you still get "IRQ FIFO error" in system log when you play stereo stream aplay -Dhw:0,0 stereo.wav 2) Did front and rear channels still swaps after first play ? speaker-test -c 4 -Dhw:0,0 -t wav As you still have 32 playback subdevices, it seem that you did not have this commit 49b9c40e9b5e47ef64f8601b84981fa45c3c4f86
>> Sometimes my sound card hangs up (It do not produce sounds. Applications which try to play something hangs). >> In this case I try to reload modules and get this bug. Have you try restart pulseaudio server ? This can be due to many reason 1) did the pulseaudio server abort and unable to respwan ? 2) it is known that au88x0 still does not support suspend/resume you have to check any error messages in system log similar to https://bugzilla.redhat.com/show_bug.cgi?id=789156
Refer to those log , it seem that au88x0 gameport is not loaded do you have any step which can reproduce the no sound problem ? can you provide a pulseaudio log when there is no sound ? i.e. open a terminal and wait until there is no sound pulseaudio -k; pulseaudio -vvvv does any error appear in pulseaudio log when aplay -v -D pulse --period-size=32 --buffer-size=96 any.wav

A number of Raymond's fixes went into the 3.4 kernel. Are you still seeing issues with the 3.4 or 3.5 kernel updates?
No, I am not seeing it, because I've changed my computer. Thank you for attempts to fix this bug.
Thank you for letting us know. I'm going to make an assumption that Raymond's upstream work has fixed this for vortex users and close this out now.
