[linux-audio-user] HDSP/MF segmentation fault problems

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



> Okay, I'm trying to be a little more fastidious about finding what's wrong.  My HDSP/MF soundcard freezes with several applications, including play, mpg321, and when I play a soundfile in audacity.  It always happens at the end of the soundfile, or if I command-C or push the stop button (in audacity) while the soundfile is playing.  It says there's a segmentation fault, and then I can't get my card to respond to any app at all (they all say the device is busy or nonexistent).  ps aux doesn't show anything at all.  When I try /sbin/service alsasound restart, I get this:
> /sbin/service alsasound restart
> 
> Shutting down sound driversnd-pcm-oss: Device or resource busy
> snd-mixer-oss: Device or resource busy

Look into /var/log/meessages, you will probably find an "Ooops" there
(that's a crash inside the kernel, it can bring the whole machine down
or - looks like your case - it affects only a driver or sets of
drivers). Once you get into that state only a reboot can cure it. 

If you find an Oops you should feed all the relevant lines into
"ksymoops" and post the result to alsa-devel...
