ERROR: Failed to open "ALSA default"
#1
Ran a library update on 4.1 (rpi3) & later found it crashed. No response from UI, ssh & ping.

Upon reboot the volume knob read 0dB. Playback appears to start but no audio output. Playback panel now doesn't respond as expected.

mpc status gives the following


Quote:ERROR: Failed to open "ALSA default" [alsa]; Failed to open ALSA device "hw:0,0": No such file or directory

Any advice on possible steps to fix?

Edit: The library update appears to have completed.

I have the same problem. Did you find a solution?

Hmmm yes - I solved the issue. It may have been something to do with my lirc setup (editing /boot/config.txt) or something else perhaps - don't really know.

Read /boot/config.txt to see if your dac driver is correctly set maybe?

Anyway I would try to solve it by setting the dac driver in audio config and rebooting. Then editing the mpd settings as instructed by the info bubble pop-up which appeared when you set your dac driver.
Basically setup your audio hardware again and reboot.

Just had the same problem on 4.3

an I2S audio device set to none (+reboot), and back to Allo Boos (+reboot) solves the problem.

In my case, I finally found that all my SMB links had been broken because of a failure of my internal network during the night. I reconfigured all of the links and after that all was OK. No more errors.

From what I read though, other users may have had other situations where they got that message and your solution would probably solve the problem.

Just to chime in I had this same issue after rebuilding a NAS with my music. Changing DAC to none -> reboot -> select dac again -> Reboot and everything is fine. I am not a linux guy. Just saying what worked for me, maybe others can benefit.
