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
And setting them to 0?
Isn't that the default value? Anyway, I tried it and the sound is still not good. (Only one 'native_blitbuffer: select error occured')
It's a little weird. The default is
Sound card with one output channel -> maxautovchans=1 Sound card with multiple output channels -> maxautovchans=0
Can you also experiment with soft mixing, (I'm forgotting what we actually call it), y'know auto-rate/format conversion.
I guess you mean hw.snd.report_soft_formats ? I tried 0 and 1, for both soundcards but the problems persists.
Anyway I decided to give up for now, the trick with reboot/demo works for me. (playing in -current is not an option; sound is OK but framerate too low probably because I can't use the nvidia AGP driver there).
Thanks for the help, at least I learned some new things about pcm! Karel.
