[SOLVED] Unable to control bluetooth volume

gregorian · 06-16-2015, 10:32 AM

Hi,

I'm running Arch with the Awesome Window Manager.

I normally control volume using the following commands:

Code:

amixer set Master 5dB+
amixer set Master 5dB-
amixer sset Master toggle

I figured out how to play audio on my bluetooth speaker and wrote the following script:

Code:

hciconfig hci0 up
pulseaudio -D
bluetoothctl << EOF
connect <mac>
trust <mac>
pair <mac>
EOF

However, my original volume control commands don't work. I've tried to adjust volume levels of many channels using alsamixer, but they have no effect.

Thank you!

Maybe the wiki will help

I've already been through them. That's how I got my bluetooth speaker and my Awesome keybindings to work.

Now I'm trying to get my bluetooth volume to work. Is there something specific in the wikis you were referencing?

pavucontrol controls the volume. Is there any unified way to control the volume?

Code:

amixer set Master -D pulse 5dB+
amixer set Master -D pulse 5dB-
amixer set Master -D pulse toggle

I made pulse audio start automatically by enabling autospawn. Using these commands controls the main speaker, but not my bluetooth speaker. I still need to use pavucontrol.

I figured that the volume in the bluetooth speaker can be controlled like this:

Code:

pactl set-sink-volume 1 +5

However, I can't hardcode sink "1". Since it is sink "0" when I don't have the speaker. What should I do?

EDIT: I solved the problem by enabling load-module module-switch-on-connect
in /etc/pulse/default.conf. Now it works.
