Some time in the last couple of weeks, PCM sound stopped working on my Debian woody system (I don't use it every day, so I can't pin down just when it happened). Of course, in that time I've done the usual number of package upgrades and so on, so almost anything could be causing this. I'd like some tips on troubleshooting, if anyone has some ideas.
The system as it is: - Machine is a Compaq 7000US (1.2G Athlon, 512M RAM) - Debian woody system with current packages - Turtle Beach Santa Cruz sound card (uses CS46xx driver) - All correct alsa modules seem to be loaded (rather than bore people with yet another module list), including snd-pcm and snd-pcm-oss I first noticed the problem when I tried to run Real Player. It hung halfway through its startup sequence. Other apps using PCM sound did equally weird things, and trying to cat a random file to /dev/dsp (i.e. the usual test) hung as well. Finally discovered esd was hogging /dev/dsp, so I disabled it. Now these programs don't hang any more, but they don't play any pcm sound either. I've tried adjusting mixer settings till I'm blue in the face, but no sound appears (although some background noise changes slightly: it's as if the PCM generator is conected to the mixer, but not producing sound). Other sound card functions, including the mixer, seem to work (although I haven't tried MIDI; don't use it under Linux). Tonight I had the idea of trying to cat a file to the alsa pcm device at /proc/asound/dev/pcmC0D0p. This resulted in: > khufu:~# cat /root/dpkg.list > /proc/asound/dev/pcmC0D0p > cat: write error: File descriptor in bad state Does this mean I have to move to another state, say, California? Or, more to the point, is this expected behaviour? Any help appreciated. .....Ron -- Ron Murray ([EMAIL PROTECTED]) https://www.rjmx.net/~ron GPG Public Key Fingerprint: F2C1 FC47 5EF7 0317 133C D66B 8ADA A3C4 D86C 74DE _______________________________________________ Alsa-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-user
