[SOLVED] Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout"

[thefitz]

Whenever I try to play a DSD file, I get:

MPD error
Failed to open "ALSA Default" (alsa);
Error opening ALSO device
"_audioout"l snd_pcm_hw_params()
failed: Invalid argument

All EQs and crossfeed etc are off, everything else works fine. DSD did work before.
