Automatically Connect Bluetooth Headsets and Enable HSP Mode for Bidirectional Audio on IGEL OS

Written by David Seeber, IGEL Community INSIDER

Hello everyone, I had a recent case where a customer wanted his Bluetooth headset to automatically be in HSP (Headset Profile) mode. By default, IGEL OS seems to connect Bluetooth headsets in A2DP mode (suitable for high-quality audio but no mic input).

However, it's possible to run a command to switch to headset mode. To achieve this, you can do the following:

  • Go to System > Firmware Customization > Custom Applications

  • Add a new Custom Application

  • Under Settings, add the following test into the Command box:


bluetoothctl connect $(bluetoothctl paired-devices | awk '{print $2}'); su user; pactl set-card-profile $(pactl list cards short | grep bluez | awk '{print $2}') headset_head_unit

  • The above command will automatically connect an already-paired Bluetooth headset and enable the "HSP" mode for bidirectional audio.

  • I found that I also had to disable the following setting so that the audio device would work correctly inside Citrix: System > Registry > ica.module.vdcamversion4support

  • To make sure that the command runs at startup, go to Desktop Integration and tick Autostart, but untick Autostart requires network

  • Lastly, if you want to, you can hide the desktop shortcut by unticking Desktop under Desktop Integration > Starting Methods.

You can check if it worked by right-clicking the desktop and opening Sound Preferences. The Audio Input tab should show Headset Head Unit (see screenshot). If this solution comes in handy for you, please let me know!
