Also, I Thanks for the quick reply! My sound devices: pcm0: <CMedia CMI8738> at io 0xa400 irq 10 (1p/1r/0v channels duplex default) pcm1: <Avance Logic ALS4000> at io 0xa000 irq 9 (1p/1r/0v channels duplex) Both sound cards have the same problem. > would suggest that you play with enabling, disabling vchans and see if I tried sysctl hw.snd.pcm0.vchans=4 sysctl hw.snd.maxautovchans=4 but it doesn't help. I'm getting a bunch of extra native_blitbuffer: select error occured > it helps. After that, you can try some patches that are floating > around that limit the fragment size. Could you provide a pointer to those patches? I googled around for a while but didn't find anything relevant. Also, I tried the following http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/sound/pcm/dsp.c?rev=1.64&content-type=text/x-cvsweb-markup in dsp.c of -stable. Although the 'ioctl SETFRAGMENT: Invalid argument' does not appear anymore, the sound is still messed up. Even worse, the trick with first starting the demo doesn't work anymore, so I reverted back to the original dsp.c . Karel.
