An update: I tried pretty much all Debian packages that play RAW or WAV files and sinthetizers. The only good result is with "saytime", that says the current time throug /dev/audio (minor 4).
Now, when I load the pcsnd module I get a message in kern.log saying Jul 21 16:20:23 d6r2 kernel: PCSP on device 3 Jul 21 16:20:23 d6r2 kernel: PCSP mixer on device 0 so I guess that pcsnd is listening on /dev/dsp (minor 3) and not /dev/audio... What's going on? I tried "ls -l" in the /dev directory to make sure that one of them is not a link and it gives: crw-rw---- 1 root audio 14, 3 Dec 9 1999 /dev/dsp crw-rw---- 1 root audio 14, 4 Dec 9 1999 /dev/audio (I didn't create the devices myself, but I assume that they were created when I installed slink or upgraded to potato...) Why does saytime work and the others don't? Anyone got any clue?
