I got around to installing mpd/ncmpcpp on my laptop and tried it out feeding the DAC directly via ALSA (i.e. Pulseaudio disabled). No surprise the track skipping was flawless with no 'buzz'. This test, in combination with Geojanitor experiencing the same issue between an rPi and another Schiit DAC with their Unison USB, is I think adequate evidence that the 'next track buzz' is down to a hardware issue between the rPi USB output and Schiit's Unison USB input.
Ah well, at least I now know the cause. Ironically of course the whole point of the Allo USBridge is the low-noise USB output, so it doesn't have S/PDIF, and there's no way I'm replacing the DAC, so I guess I'll just have to put up with it
Thanks all for your troubleshooting input even though we didn't arrive at a solution,
