I've always had that problem on my patched freebsd 5 (had it setup for
months) system. Scrolling (scroll lock) will do it to... It may help
to play with the sysctls for:
hw.snd.pcm%d.buffersize:
Configure the amount of DMA bufferspace available for a device....
jack this up to like 16384
hw.snd.targetirqrate:
Set the default block size such that continuous playback will achieve
this IRQ rate. This value can
be tuned to improve application performance. =20
Increase this value when the sound lags and decrease it if
sound stutters or breaks up.....
just this up to
You set them with loader.conf, here's what I have in mine:
hw.snd.maxautovchans=3D4
hw.snd.targetirqrate=3D36
hint.pcm.0.buffersize=3D"16384"
You can check it with: sysctl -a hw.snd=20
