Description Adam Kozakiewicz 2003-10-13 08:59:25 UTC
From Bugzilla Helper:
User-Agent: Opera/7.21 (X11; Linux i686; U)  [en]

Description of problem:
This bug is most often triggered by Opera. Once in a while a sound being played 
stops with a click and sound becomes unavailable (/dev/dsp in use). lsof doesn't 
show any process using /dev/dsp, killing mostly everything doesn't bring sound 
back. Trying ogg123 from the console showed me the message:

Assertion failed: chan->is_active==sg_active(chan->iobase),via82cxxx_audio.c, 
via_chan_maybe_start, line=1389

The machine has to be rebooted to get the sound back (the modules are reported 
as in use, can't rmmod them).

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Run Opera with sound played for incoming mail and/or finished transfers for 
some time.
2. Be unlucky - the bug appears at random, about 3-5 times a week under heavy 

Actual Results:  Sound stops, the device is locked until reboot

Expected Results:  Normal playback. If not possible (a bug in Opera?), closing 
the program should restore sound, the module shouldn't lock up, a reboot should 
not be necessary.

Additional info:

I think it might be caused by Opera trying to play a second sound while the 
first one is still playing, but it's just a feeling.

Opera runs as a normal user and should not be able to disrupt any part of the 

Athlon MP1600+, VIA KT133, sound from VT82C686 AC97

Thanks for the bug report. However, Red Hat no longer maintains this version of
