[Voyage-linux] Re: Glitches on Playback Start/Resume with Arcam rDAC and Voyage MPD 0.8

The momentary frequency difference is normal. Its how the feedback keeps the
rate of data transfer in sync with the dac. 

There are issues with the UAC2 driver in Linux similar to what you are
seeing. Its standards compliant, but a little different than the OSX driver
and handles the rate feedback differently. With luck and time the
differences will get ironed out by the ALSA guys. We are waiting for someone
to show them exactly where the issues lie. Without a USB2 sniffer its very
difficult to capture the underlying issues.

Meanwhile, except for the sample rate shift issues it works quite well for
most UAC2 DAC's (the ones using XMOS or Audio Widget interfaces). It doesn't
work well with Tenor or CMedia chipsets.
