 Posted: Fri Jul 08, 2022 9:08 am Post subject: Using pnmixer, can I control BlueTooth audio devices? |
 |
|
I have Apple Airpods and some Sony WH 1000 XM3 headphones.
I use either on my Gentoo box watching Youtube using Chrome or Firefox.
The Youtube volume control works.
The Sony slide up and down on the right ear cup changes the volume.
But pnmixer in my icons tray of Fluxbox, which works if I am using speakers and the on-board sound chip, works, but does not work with the BlueTooth devices.
I have the volume control command set to | Code: | | /usr/bin/amixer -D pulse sset Master playback |
Can I control my Bluetooth devices volume using pnmixer?
I note, in my system log, when I connect the devices, the following:-
| Code: | | Jul 8 18:11:36 Lyalls-PC pulseaudio[21754]: [pulseaudio] bluez5-util.c: org.freedesktop.DBus.Properties.Get /org/bluez/hci1/dev_7C_C1_80_0D_D9_C9/fd41 Volume property not (yet) available |
so, maybe I don't have an appropriate kernel module installed.

hello,
please read the wiki (again), your device is even listed to work and also there's a tip regarding your problem at the end.
why not use pactl as mixer?!
https://wiki.gentoo.org/wiki/Bluetooth_headset
from wiki:
| Quote: | | Audio device not visible using PulseAudio volume control (but working with ALSA) |
| Quote: | | According to this forum post, add the following to /etc/pulse/default.pa (and possibly /etc/pulse/system.pa): |
| Code: | /etc/pulse/default.pa
### Automatically load driver modules for Bluetooth hardware
.ifexists module-bluez5-device.so
load-module module-bluez5-device
.endif
.ifexists module-bluez5-discover.so
load-module module-bluez5-discover
.endif |
| Quote: | | Ensure that the pulseaudio and bluetooth USE flags are enabled |
for example, i have this in my sway config:
| Code: | # Pulseaudio wob
bindsym XF86AudioRaiseVolume exec pactl set-sink-volume @DEFAULT_SINK@ +1% && pactl get-sink-volume @DEFAULT_SINK@ | head -n 1| awk '{print substr($5, 1, length($5)-1)}' > $WOBSOCK
bindsym XF86AudioLowerVolume exec pactl set-sink-volume @DEFAULT_SINK@ -1% && pactl get-sink-volume @DEFAULT_SINK@ | head -n 1 | awk '{print substr($5, 1, length($5)-1)}' > $WOBSOCK
bindsym --locked XF86AudioMute exec pactl set-sink-mute @DEFAULT_SINK@ toggle
bindsym --locked XF86AudioMicMute exec pactl set-source-mute @DEFAULT_SOURCE@ toggle |
it's not an bluetooth device, but i think it'll work anyway if your BT device is configured correctly.
greetings

pacmd works for me.
The following script, does indeed control my bluetooth headphones (found on forums)
| Code: | #!/bin/bash
VOLUME="$*" # '+10%' '-10%'
for SINK in $(pacmd list-sinks | grep 'index:' | cut -b12-)
do
pactl set-sink-volume $SINK $VOLUME
done
|
However, I use pnmixer in my Fluxbox systray and it does not control the Bluetooth headset volume, even if I update the mixer setting to use the above script.
I already use pavucontrol, which does work, but I was hoping to have a systray app that works, because pavucontrol is too complicated for my use case.
