I had the same problem, and it turned out that changing the Crystal audio's IRQ helped. I have a PR440FX dual PPro board with the same chipset. Any IRQ under 8 seemed to work fine (it is currently at 5, also works at 7). Check your dmesg output and see what it is currently sitting at. If it is 9 or above, you may need to play around until you either can set it to 5 or 7, or the PnP system in your BIOS does it for you. Oddly enough, this appears to be a BSD specific problem. The previous owner of this box used Linux, and the subsystem worked fine at IRQ 9. Seth Henry jshenry@net-noise.com >>> I have the following error after playing one song, and no sound anymore: pcm1: play interrupt timeout, channel dead This is an out-of box 4.2-RELEASE (just pcm driver added) with a CS423x soundcard which worked fine on 3.3-RELEASE This has been reported often on the lists but afaik not after 4.2 was released. the suggested patch (uncommenting chn_dmaupdate(c);) was already done in 4.2-RELEASE. I commented it again, turned off PnP and all that, no luck. Any idea what I can do ?
