[mythtv-users] RE PVR 350 sound

[Paul Onley]

I run Mandrake 9.0 and when I installed on a new (to me ) IBM PIII 450 with 
onboard sound I got a similar message with sound apps, turns out that the 
onboard sound on my IBM only had 1 dsp and once something had it nothing else 
could use it. I installed a sound blaster 512 PCI and all my problems are 
fixed. I don't know what kind of sound support your MB has or if this will 
help but just thought I would pitch in my 2 cents.
