can't set card profile of bluetooth device to a2dp_sink #7

This problem is currently seen on my branch no_alpine_pulseaudio_image

Note that I can set the card profile to off !

Rebooting and executing the following instructions didn't work:

pacmd set-card-profile 2 off
bluetoothctl
disconnect <mac address>
connect <mac address>     (allthough this connect doesn't seem needed as it automatifally reconnectes)
pacmd set-card-profile 3 a2dp_sink   ( card number got increased after disconnect)

Same problem when using branch alpine_pulseaudio_image

Strange enough setting the card profile to off or headset_head_unit works, but changing to a2dp_sink never works as you can see in the log below.

To check

This file doesn't exist in my host OS.

janvda commented 5 years ago

I have switch on/off my bluetooth speaker and after that I succeeded in changing the profile to a2dp_sink

janvda commented 5 years ago

I close the issue. Switching the bluetooth speaker off/on fixed the issue. So it looks like the bluetooth speaker got in an incorrect state causing the issue.

janvda commented 5 years ago

This problem seems to be caused when doing a disconnect in a bluetoothctl session after the speaker has been connected.

So it is related to issue https://github.com/janvda/balena-pulseaudio/issues/5
