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.

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

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 .
