Getting around to trying to solve a long-standing problem.
rasptouch running current release of ropieeexl.
As a roon endpoint seems very stable - no dropouts
When used as the audio out of my mac (over ethernet), sometimes plays well for hours, sometimes skips, hisses, and has dropouts.
Looking at the dmesg output I see some under-voltage errors.
(I bought a linear power supply after checking the spec with audiophonics.fr)
Think this could be related? Somewhere I have the original power supply and I could try that…if I could find it!
Thanks.
