I can confirm what Mojo is hearing
- I also get a sharp static/click when turning the Vol all the way to 0 and a song is still playing. It happens on Mains and Battery power. The static/click will stop if you stop playing. The frequency of the static/click seems to correspond to the tempo of the bass and the sharpness to the peak. On soft songs with little bass you don't get the click.

EDIT - Good news is I don't think it is hardware related as the issue seems to be confined to Volumio (no issue with my side loaded JRiver Media Center)

- I have also had (but can't reliably reproduce) what sounds like EFI at times during playback.
