Then why not provide a backtrace in the ticket?
The 8509 ticket is unfortunately close to useless.
It does not provide any information that could actually help diagnose
/dev/dsp is OSS audio
The PCM checkbox is only necessary when using multichannel audio.
What happens if you leave the audio config like it was before? (ALSA:plughw,1,0)
