In relation to -b and -B and Windows MME drivers, anything smallerthan 1024 or 2048 will cause drop-outs because that particular modeof output can't have any smaller buffers (it sits in front of a mixer thatprevents that).If you are using a GUI, it's most likely this that is setting the devicenumber and you will have to set it there. Otherwise a -odacN wouldset device N.Victor----- Original Message -----From: Jim Aikin <midiguru23@sbcglobal.net>Date: Friday, July 31, 2009 10:25 pmSubject: [Csnd] Re: Re: RE: Re altime Audio Output GarglingTo: csound@lists.bath.ac.uk> > > Michael Gogins-2 wrote:> > > > I'm afraid this is a little bit complex.> > > > PortAudio does see the -b and -B options, and they do matter.> > > > Your vague suspicion is, I think, the case., Plain -dac > defaults to> > whatever Windows thinks is the audio output.
