Bluetooth - MPD Error - failed to open ALSA Bluetooth
#3
Thanks for the quick response Tim. I tried a fresh install of the new 8.2.3 version and made the following changes after flashing the boot media:
(1) configure wifi (REDACTED) below is my WLAN SSID
(2) change the hostname to moode40 in the system menu
(3) under the renderers menu, turn on the bluetooth pairing agent and turn on the bluetooth controller
(4) in the bluetooth control menu, change the audio output to "bluetooth speaker"

Wondering if my speaker itself was part of the problem, I decide to pair a set of bluetooth headphones I know work. The pairing went as expected,  the device was listed in the moode bluetooth interface and the flashing led on the headphones indicated a successful pairing event. I then returned to the library and selected a radio station and pressed play. I get the same error as previously:


"MPD error

Failed to open "ALSA Bluetooth" (alsa); Failed to open ALSA device "_audioout": Invalid argument"

The code block below shows the output of moodutl -l. Does that suggest anything to you that I can investigate?

Should the line "20221219 200915 worker: MPD output 2 ALSA Bluetooth (Off)" say Bluetooth (On) at the end instead?
