When using a frame size on the pull side of 8192 bytes (1024 frames á 8 bytes),
I can see that several CopyTo calls add up totalling 8192 bytes during each frame
period. The audio plays fine aside from the fact that each 10 seconds, a very short
glitch occurs (like a dropout), and I have not been able to pinpoint how or why. My
ringbuffer neither underruns, nor overruns, nor can I see a difference in the CopyTo
behavior.
I'm at a loss here. Does anyone have any idea what to check ?
To further complicate things, the glitches occur only when I run:
- Foobar2000 with DirectSound output
- Spotify
but not when running:
- Foobar2000 with KS output
- WMP
if that should trigger the ringing of a bell... ;)
Regards,
/Rob
Ps. The glitches occur on Vista 32 & Win7 64
