Bluetooth headset
This article describes the configuration of Bluetooth headsets within Gentoo Linux.
Prerequisites
The configurations for Bluetooth and ALSA must have been previously completed (just configurations, some devices do not connect without media-sound/pulseaudio-modules-bt or media-sound/bluez-alsa setup).
Also, ofono-headset USE flags might be useful:
/etc/portage/package.use/pulseaudiomedia-sound/pulseaudio ofono-headset
media-sound/pulseaudio-daemon ofono-headset
Configuration
PulseAudio
Following instructions from PulseAudio and BlueZ 5 should be sufficient to make Bluetooth headsets work (through pavucontrol for instance).
There is two protocols for handling microphone input (and button input) from headsets: HSP and HFP. In order for the microphone to work the headset has to switch from the A2DP protocol to HSP/HFP. Headset using HSP will usually work out-of-the-box with the current pulseaudio version.
pulseaudio 13.0 does not support HFP properly. There is ongoing work on this. You might have luck building the current development version from source using this merge request 288 and the accompanying hsphfpd.
ALSA + Bluez 5
You can use bluez-alsa to provide integration between Bluez and ALSA. This setup can be used either completely without Pulseaudio, or you can then use your headset as another ALSA device in Pulseaudio (in which case disable its bluetooth support, so the two don't collide).
Install bluez-alsa:
root #emerge --ask media-sound/bluez-alsaIn your ALSA configuration, /etc/asound.conf (system-wide) or ~/.asoundrc (user-level), specify the parameters of the Bluetooth connection (replace the MAC address with the MAC address of your device):
/etc/asound.conf or ~/.asoundrc# Bluetooth headset
defaults.bluealsa {
interface "hci0" # host Bluetooth adapter
device "10:4F:A8:00:11:22" # Bluetooth headset MAC address
profile "a2dp"
}
A static ALSA configuration is also possible, make sure to change the device name in the below examples for aplay.
/etc/asound.conf or ~/.asoundrc# Bluetooth headset
pcm.btheadset {
type plug
slave.pcm {
type bluealsa
device "10:4F:A8:00:11:22"
profile "a2dp"
}
hint {
show on
description "Your description of Bluetooth Headset"
}
}
Make sure the bluetooth and bluealsa services are started. You probably want to add them to your default runlevel via rc-config. Make sure the device is paired and connected to your computer (see Bluetooth for details) and test with aplay, passing the PCM device bluealsa:
user $aplay -D bluealsa some_file.wavFor other applications, the precise option to set the output device may differ.
Changes to ALSA configuration files /etc/asound.conf and ~/.asoundrc are picked up automatically at application start, you don't need to restart the alsasound service.
Hardware volume control:
user $alsamixer -D bluealsaTesting
Play a sound file with mplayer:
user $mplayer -ao alsa:device=bluealsa filenameOr with mpv:
user $mpv --audio-device=alsa/bluealsa filenameIf it works, please add your device to the table of working devices.

| Apple AirPods (1st generation) | Yes | No | 5.54 | Recording is probably same as AirPods Pro. | |
| Xiaomi Redmi AirDots | Yes | No | 5.54 | There might be a way to make the microphone work, if you mess with pulseaudio and manage to get HSP/HFP to work, but I couldn't do it. | |
| CaseGuru CGpods 5.0 | Yes | Not tested | 5.54 | ||
| Soundcore Life Q30 | Yes | Yes | 5.55 | Playback via Pulseaudio worked with A2DP out of the box, attempts to get the microphone work via HSP/HFP were unsuccessful with both native-headset and ofono/phonesim mess. I was able to get it working with bluez-alsa and then added the device to Pulseaudio as described on bluez-alsa wiki. |
Troubleshooting
Can't open input device
Compile and load the uinput kernel module, when things don't work, and the logs show this error:
bluetoothd: Can't open input device: No such file or directory (2)
bluetoothd: AVRCP: failed to init uinput for 00:16:44:FD:6B:A0
bluetoothd: Unable to select SEP
Device Drivers --->
Input device support --->
[*] Miscellaneous devices --->
<M> User level driver support
No audio service is available
After updating to net-wireless/bluez-5.xx it might happen, that a Bluetooth headset is connected, but ALSA/PulseAudio fails to pick up the connected device.
An error message like this might be shown in the output of PulseAudio:
I: [pulseaudio] module-card-restore.c: Restoring profile for card bluez_card.00_16_94_0B_6F_DE.
I: [pulseaudio] card.c: Created 10 "bluez_card.00_16_94_0B_6F_DE"
bt_audio_service_open: connect() failed: Connection refused (111)
W: [pulseaudio] module-bluetooth-device.c: Bluetooth audio service not available
W: [pulseaudio] module-bluetooth-device.c: Service not connected
I: [pulseaudio] card.c: Freed 10 "bluez_card.00_16_94_0B_6F_DE"
E: [pulseaudio] module.c: Failed to load module "module-bluetooth-device" (argument: "address="00:16:94:0B:6F:DE" path="/org/bluez/31716/hci0/dev_00_16_94_0B_6F_DE""): initialization failed.
To fix this, the following needs to be done:
- Enable the audio socket of bluetoothd:
/etc/bluetooth/audio.conf[General]
Enable=Socket
- Restart bluetoothd by doing one of the following things:
- Turn the software wireless kill switch off and on again
root #rfkill block bluetoothroot #rfkill unblock bluetooth- Turn the hardware wireless kill switch off and on again
- Reboot the computer
- Reconnect the Bluetooth headset
Audio device not visible when using GDM
If you are using GDM, but not logging into GNOME (e.g. i3 instead), GDM might block your headset, which will it not being available for PulseAudio. This will result in your headset being connected, but the applications won't see it.
As a workaround, you can switch to a different display manager (e.g. LXDM), or disable PulseAudio for GDM[1]:
/var/lib/gdm/.config/pulse/client.confautospawn = no
daemon-binary = /bin/true
If you have created the file, make sure that GDM can read it:
root #chown gdm:gdm /var/lib/gdm/.config/pulse/client.confAudio device not visible using PulseAudio volume control (but working with ALSA)
According to this forum post, add the following to /etc/pulse/default.pa (and possibly /etc/pulse/system.pa):
/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
Ensure that the pulseaudio and bluetooth USE flags are enabled
