When I play the track on audacity via USB cable to external amplifier, the first second or two are missing, they are not played.
To avoid this, I need some other music playing directly from the mac via a web browser or a quicktime instance running in the background.
This happens only when I use external amplifier connected via usb cable and port to the mac.
And only with audacity playback.
Can someone help me with this annoying and strange behaviour?
