I forgot to mention that I did try the latest Stable source (I believe it was #6) and had the same problems. I also failed to mention that I tried adding "device csa" in my kernel config (as well as "options PNPBIOS" and "device pcm"....in fact, I tried every permutation of these three and nothing worked (of course, the kernel wouldn't recognize the chip without option PNPBIOS).

Okay, thanks for checking. Now it's up to Cameron to figure out :-)

I did manage to try OpenBSD 2.8 and the sound card worked fine. Of course, compiling some applications was "challenging" so I wiped it clean and put FreeBSD 4.3 on. I haven't compared the pcm driver on OpenBSD to that on FreeBSD (perhaps I'm being too simplistic is assuming that the underlying architecture is similar...) Let me know if you need any other information or if I can be of help in any other way. Regards, Sam Sound works fine (as does the Lucent modem) if you follow the directions located here (even though this is a A21p, the information is valid for the T20 as they share the same sound card (CS4614) and modem): http://www.personal.psu.edu/faculty/r/e/reh18/A21p/A21p.html Basically, you have to patch csa.c (I believe the patch has already been committed to the source tree) and recompile the kernel with only "device pcm" "device csa" (you don't need "options PNPBIOS"). (also note that you must go into the bios configuration and disable the power management for pci as descibed above).

I have a CS4624/CS4297a. (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) > 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). Regards, Sam 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.
