Re: [Gwc-general] sound only in little bursts

[Jeff W. <we...@ya...>]

Hi all,

Sorry to be late answering, I was on the road all last week.  I have to 
get my taxes filed in 2 days so I
can't spend any time digging into this right now.  As I recall, in the 
audio util section, it queries the sound
driver to find out how many bytes it can throw at the playback device.  
My first guess is that the playback
device is reporting there is no room in it's buffers, and that's why gwc 
is showing the bytes_left staying
constant.
