Hi!

Since last week I got sound working on an IBM Thinkpad 600X, it has an
AC97 compliant mixer and a CrystalMedia chip:

FreeBSD Audio Driver (newpcm) Aug 30 2000 22:28:41
Installed devices:
pcm0: <CS461x PCM Audio> at irq 11 (1p/1r channels duplex)

(using csa bridge)

Now comes the problem: 

/dev/dsp and it's friends report "device busy" for a long time (somtimes
forever) after the computer have been suspended (zzz). The following
line appears in dmesg output when the computer is resumed from suspended
mode:

pcm0: play interrupt timeout, channel dead

Is it possible to "re-init" the audio-device after this resume from
suspended mode to get the device work again?
