I sent this message on the freebsd-mobile mailing list. Since it is related to the newpcm/csa driver, I think folks on the hackers list may be able to help. Summary: - newpcm/csa driver on 4.2-stable doesn't work on my thinkpad a20p - Same laptop with NetBSD 1.5, it works fine (clcs driver) Question: - Should I try to "hack" the current csa/newpcm bridge stuff, or port the clcs driver from NetBSD I've inserted debug code (read printf's) inside the pcm and csa driver and the interrupt routine inside csa.c never gets called. The pcm routine writes down to the snd0 device and eventually times out with "play interrupt timeout, channel dead". Suggestions welcome.

The sound device is correctly detected and works fine. So the problem is really with the csa driver in FreeBSD. The "newpcm" driver seems to use a bridge between the pcm and csa driver. In NetBSD/OpenBSD, it a driver on its own (clcs). My first guess to make this work would be to port the clcs driver to FreeBSD. Can anyone give me a do/don't about this (bad idea/too much work/...) ? Or is anyone currently on this ? Florent.
