Trying to get Audio via Bluetooth running

Archive - Mycroft Project Picroft
1

Hi there,
I am running Picroft on a new Raspi4 after following this Install guide that worked out of the box. Nevertheless I didnt get any of three tested bt devices (Anker Soundcube, Bose QC35, Skullcandy Hesh 2) running though they got paired and connected to the RP4. They even are shown and selected in the audio menu within the Raspbian Desktop, but sound still only is working via HDMI output. Attached a log, maybe one of you guys has any idea how to get this working.
Cheers and Thanks
Kelvin

See if this provides any help?

Hi Kelvin,

The link baconator provided has a number of things to try. Did any of those work?

Did any of the devices work with the Mycroft audiotest?

Thanks, I went through it, logs attached. What I stumbled over:

  • After “this usually indicates that mycroft can’t find pulseaudio. Make sure it’s installed and mycroft is able to access it.”
    There is a dedicated “pi” user but no “mycroft” user though mycroft is running (told me the pairing code
)
  • Had some trouble installing " pulseaudio-module-bluetooth" before. For unknown reasons, installation worked now.
  • I also followed this guide. Even when headset connected, there is no bt device found
    " Let’s go back to PulseAudio, display current sound cards.
    pacmd list-cards
    You’ll find two, the built-in one of Raspberry Pi, and the headset one:
    bluez_card.xx_xx_xx_xx_xx_xx"

Thanks
Kelvin

I decided to go the easy way and ordered a Respeaker-4-Mic-Array.
Nevertheless I would be eager to know how to get BT stuff running. The Bose QC35 is my ultimate “commander headset” =D
