/dev/dsp /dev/audio missing

[richard bader]

Hello,

I've a working soundcard on a machine running FreeBSD 6.2-RELEASE-p9.

The same soundcard on an other machine running 8.0-STABLE FreeBSD
8.0-STABLE #3 doesn't word.
There in no device /dev/dsp. /dev/mixer exists.

Any hints?

richard

I think these devices are created by demand in FreeBSD 8 and 9.
