Failed to open audio output

Help and Support Help
1

Hi, I have a pi Zero W, with a Justboom DAC Zero, running Volumio 2.118.

I installed Volumio following the instructions here:
https://volumio.org/forum/with-new-rpi-zero-t6050-30.html#p30027 from@macmypi

I then set up Volumio following the instructions here:
https://www.justboom.co/software/configure-justboom-with-volumio/

However, I get the error “Failed to open audio output”. Any ideas why this might be happening or how I can troubleshoot?

Thanks, James

You can follow logs from a ssh session (sudo journalctl -f), or you can send a log from the Volumio UI (deviceIPaddress/dev). In either case, make sure that you cause the error message (by playing a track or whatever). If you upload a log then please include your username as well as a description of the problem.

Thanks @chsims1

I seem to have got past the “failed to open audio output” error by installing Volumio 2.129.

However, I’m not getting any sound out of the Justboom DAC Zero. I will have a look at the logs when i get home, as you suggest, and see if that helps.

I’ve had a look in the log:
volumio mpd[1769]: alsa_output: Failed to open “alsa” [alsa]: Failed to open ALSA device “hw:1,0”: No such file or directory
volumio mpd[1769]: output: Failed to open audio output
volumio mpd[1769]: player: problems opening audio device while playing “http://listen.radionomy.com/musicwire-livethesound”

I’ve also used the aplay command:
**** List of PLAYBACK Hardware Devices ****

Subdevices: 8/8

Does the above mean that my Justboom DAC Zero isn’t working?
