Use Seperate Bluetooth device for audio

[predsfan2]

I have set up Hudiy in my Skoolie with a Raspi 4. I plan on using it wirelessly. (For some reason wired AA wasn't working on my Z-Fold7)

I would like to figure out how to get any audio (spotify, map guidance, ect) to run through my headphones connected to my phone's bluetooth. I don't have any sort of audio sytem connected to my raspi. I couldn't seem to find a solution to this at the moment. Maybe I'm missing a setting in the Hudiy config? Any help, guidance, or pointers would be great.

You can disable speechAudio and mediaAudio in androidAuto section of $HOME/.hudiy/share/config/main_configuration.json

Disabling them will let the phone decide how to route the audio (e.g., via A2DP, Jack).

Please note that the .hudiy folder has a dot in its name, which means it's hidden. You can enable showing hidden files in the file manager using CTRL + H, or you can edit the files from the terminal using a tool like nano, for example: nano $HOME/.hudiy/share/config/main_configuration.json

I hope it's ok if I piggyback a related question...

I have disabled speechAudio and mediaAudio, and after enabling registerDummyHfpProfile and registerDummyA2DPProfile my phone now plays audio over my bluetooth headphones as desired. I can still pause/play and otherwise manage the audio app (Qobuz) with Android Auto on Hudiy, which is great.
However I still want to control the volume with Hudiy, as this will be installed on a motorcycle and it's easier to use volume controls on the Hudiy unit instead of fumbling with the controls on the headphones. Is this even possible?

If it matters I'm using a RPi 4 and Raspbian Trixie.
