Hi there,

I have two problems with sound in Linux (Mandrake 9.2).

The first of these is a problem of only one application being able to
use the sound card at a time. For example, if I am listening to music
with /usr/bin/play and I run MozillaFirebird I get a message telling me
that "/dev/dsp: Device or resource busy". I have tried a program called
esddsp to run the two programs (not really sure what I'm doing here) but
it makes no difference.

My sound card is (I think) an Intel i810 (it's on a Sony Vaio
PCG-R600HEP laptop).

The second problem is that sometimes when I boot (this is sporadic, I'm
not sure what causes it specifically -- might be which programs I run
first or something), all the sound plays at the wrong speed. Taking the
example of /usr/bin/play, I get a message from sox (I don't have the
actual error message at the moment as the sound is working) saying
(roughly) that it is "Unable to set audio speed to 44100 (set to 39400)"
and the sound comes out the sound card at a much higher tempo than it
should (and hence sounds odd!). I have tried with mplayer and get
similar results.

Can anyone offer any help with either of these problems please?

If there is any more detail that is needed, please let me know and I
would be happy to post it.

Many thanks in advance,

Al
