Failed to open "ALSA Bluetooth" (alsa); Failed to open ALSA device "_audioout": No su - springle19 - 05-11-2025
Folks, would appreciate any insights on solving the above error
Variables as follows:
> Moode 9.3.3 2025-04-29, running on RaspPi 4, with ProtoDac HAT
> successful Bluetooth pairings with a (i) Google Nest and (ii) a Anker/Soundcore Bluetooth speaker. No issues with their co-existence, and both work faultlessly as audio outputs all the time
> implies nothing fundamentally wrong at the Moode end
What prompted the error:
> tried this AM to Bluetooth-pair Moode with my Android 12 phone
> phone was discovered by Moode, and pairing apparently completed
> however, when I try to output audio via Bluetooth to the phone, Moode throws the 'Failed to open "ALSA Bluetooth" (alsa); Failed to open ALSA device "_audioout": No such device' error
Actions so far:
> with a separate paired Android 10 phone, I get the same error message in Moode
> have rebooted Pi, but get same error when trying to output audio to either Android phone
> in the Bluetooth config screen have deleted all pairings, and tried both phones again - same error message occurs
Any pointers gratefully received
Best, Simon P

You are trying to send moOde audio to your phone over Bluetooth? I suspect your error is because the phone isn't a Bluetooth speaker device. Phones tend to expect to send their audio over Bluetooth rather than receive audio.

Thanks, Robert. I'll dig around more re the phone's functionality. Helpful to get your fresh eyes!
