I can almost hear the original content, but it is interrupted every second or so, and it plays at a slightly slower speed than when everything is working fine.

Ok, a little more debugging, the only sampling rate available in digital model on this MBP are: 44.1kHz, 48kHz and 96kHz ; no 192kHz.

Any particular reason this sampling rate isn't available in digital mode? Surely, there aren't any hardware restriction on the matter..

Thanks
