Hi,
When I use skype, just call anyone then hang up it. Then, the skype can not=
open
the dsp device again. fstat shows that no process is opening
/dev/dsp*. But, /dev/sndstat
shows:

You may notice that pid 1004 is using record and dsp0.2, this process
is skype_bin.
If I close skype, /dev/sndstat still shows that pid 1004 occupies record ch=
annel
and dsp0.2 (but ps shows that there is no pid 1004). Any ideas?
I'm running -CURRENT around March 22 on i386. I dont think I have this prob=
lem
in Feb or in Jan. I will try do a binary search later (In fact, I
tried to boot with Feb
1's kernel, but got a panic about 'bad dir' :-().
Thanks,
