Leliel loses connection to Topping D30 DAC randomly #1

Closed jakubgs closed 2 years ago

jakubgs commented 3 years ago

When playing music with MPD via my Topping D30 DAC it randomly stops playing. As if it loses conneciton.

I have tried disabling USB suspend functionality on leliel but it doesn't seem to have resolved the issue: https://github.com/jakubgs/nixos-config/blob/d11e07b0587308e46a3fd2514e3f7ad8dd70141e/hosts/leliel/configuration.nix#L84-L91

When it happens - mpd stops playing - and I try to play something using aplay I get this:

 > aplay something.mp3
Playing raw data 'something.mp3' : Unsigned 8 bit, Rate 8000 Hz, Mono
^CAborted by signal Interrupt...
aplay: pcm_write:2061: write error: Interrupted system call

No longer an issue, might have been a faulty cable.
