Just read an interesting post by HQPlayer Jussi Lasko. Sound familiar?
Typical known problem on RasPi hardware are lost USB microframes (125 µs) on USB Audio Class protocol which happens due to USB bus load pattern and the way hardware/OS stack handles it.
On some hardware this causes small ticks in the sound, like dust particles on vinyl. On some other DAC the symptoms may be different, depending on how the DAC handles such lost frames.
Makes me wonder if dropped microframes could be the basis of the 2Go problem? If true, I’d bet this is more likely a software than hardware problem.
