> 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 > snd-hdsp: Device or resource busy > snd-pcm: Device or resource busy > snd-timer: Device or resource busy > snd-rawmidi: Device or resource busy > snd-seq-device: Device or resource busy > snd-hwdep: Device or resource busy > snd: Device or resource busy > [ OK ] > ALSA driver already running > Sound driver snd-hdsp is already loaded 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... -- Fernando
