(It's a T20, model 2647 44U) I'm having problems getting sound working properly: I've almost got it working but when I play an mp3 file (or use XMMS), I get: pcm0: play interrupt timeout, channel dead I'm using FreeBSD 4.2 Stable and I recompiled the kernel with (and all the permutations of...) options PNPBIOS device pcm > cat /dev/sndstat FreeBSD Audio Driver (newpcm) Feb 7 2001 22:00:05 Installed devices: pcm0: <CS461x PCM Audio> at irq 11 (1p/1r channels duplex) > >How-To-Repeat: Compile the 4.2 Release kernel on the IBM T20 (model 2647 44U) (which IBM claims is a CS4624/CS4297a chip). Then reboot, and play an mp3 file. You should hear nothing and see pcm0: play interrupt timeout, channel dead in your /var/log/messages. The mixer seems to work fine (contolling volume on the CD player) and I can play CD's and hear the music. >Fix: None that I know of. I've asked on freebsd-questions and freebsd-mobile and the consensus is that it's a bug. (let me know if you need a tester).
