[SOLVED] CamillaDSP - MPD unable to play flat.yml

[bitlab]

@katariat nothing in the logs that clarifies the issues. Only the error the following error, but that provides not enough info:

Code:

May 01 13:32 : exception: Failed to play on "ALSA Default" (alsa): snd_pcm_poll_descriptors_revents() failed: No such device

If you feel comfortable with the command-line terminal, you could try to increase the log output of camilladsp by editing the file /etc/alsa/conf.d/camilladsp.conf (requires sudo).
Make -v argument comment and add the -l debug to the section below:

Code:

###############################################
# Uncomment the following lines,              #
# if you want more detailed logging output in #
# /var/log/mpd/log                            #
###############################################
  cargs [
#        -v
       -l debug
       -p "1234"
       -a "0.0.0.0"
  ]

}

Start playback again and the look/post the /var/log/mpd/log again.

In my case this looks like:

Code:
