Re: [Bayonne-devel] cannot open /dev/dsp

[David Sugar]

The soundcard test driver users /dev/dsp.  If your soundcard driver has no 
/dev/dsp, or it cannot open it for write (permission issues for example) then 
you will hear nothing :).

Also, Bayonne does not do rate resampling, and hence it will NOT sound correct 
on broken soundcards that only operate at 44khz.
