Contribute to arkq/bluez-alsa development by creating an account on GitHub. This is typically done using a small headset that fits over one ear. This supports the LDAC and SBC codecs. Jan 21, 2026 · As Bluetooth audio evolves—especially with LE Audio and ISO-based transports —the roles of BlueZ, ALSA, and modern audio servers continue to shift toward tighter integration, improved synchronization, and more flexible routing. my bluetooth headphones only work with pulseaudio. This project created and maintains a product called BlueALSA, with which one can achieve the same Bluetooth audio profile support as with PulseAudio, but with fewer dependencies and at a lower level in the software stack. bluealsa is a Linux daemon to give applications access to Bluetooth audio streams using the Bluetooth A2DP, HFP, HSP and/or BLE-MIDI profiles. -V bluealsa is a Linux daemon to give applications access to Bluetooth audio streams using the Bluetooth A2DP, HFP, HSP and/or BLE-MIDI profiles. BlueAlsa [2] is a Bluetooth audio backend for ALSA. It bridges the gap between BlueZ 5 (the Bluetooth stack) and ALSA (the audio stack) without the need for PulseAudio (a fat sound server). Follow the instructions on the BlueALSA GitHub page to install it. This post shows steps to setup Bluetooth audio sink on Raspberry Pi using bluez-alsa. Bluetooth audio sink (A2DP sink) enables Raspberry Pi to receive audio from other Bluetooth devices (e. OPTIONS ¶ -h, --help Output a usage message and exit. At the second search I did found the Project How do I connect bluez-alsa to an audio device? It works with pulseaudio so I know it works, generally speaking.

These are currently for talking to the headset daemon that transfers sco audio over hci. how can i get them to work with alsa too? ty. g. It provides a D-Bus API to applications, and can be used by ALSA applica‐ tions via libasound plugins. c would be a good reference for how to integrate with alsa. It provides a D-Bus API to applications, and can be used by ALSA applications via libasound plugins (see bluealsa-plugins (7) for details). -V Bluetooth Audio ALSA Backend. Aug 8, 2025 · This integration allows standard ALSA applications to use Bluetooth audio devices without modification, presenting them as standard ALSA PCM and control devices. How do I configure ALSA's asoundrc file to input and output audio data to two Bluetooth devices? I have tried using the dmix and dsnoop plugins to go about doing this similar to what is shown in the 9 On my laptop, I have an onboard sound card, and also a connected bluetooth headset. Enhance the headset service to do a2dp services The a2dpd daemon from plugz is the best example for signaling and talking with the headset. bluetooth { type bluetooth device 12:34:56:78:9a:bc profile "auto" } ctl. conf: # cat /etc/asound. The integration consists of two main components: a PCM plugin for audio streaming and a CTL plugin for mixer controls. I have configured the bluetooth device in /etc/asound. bluetooth { type bluetooth } Now I can play audio to my headset by specifying the new audio device • A consequence of the alsa-lib implementation of controls is that when one Bluetooth device connects or disconnects it is necessary to remove all controls from all devices in the mixer and create a new set. fixb, es6l, gvw7, mbec, mgos, xrfq, lbloo, 8hrmib, nzui, uhb1n,
