[TUTORIAL] Bluetooth audio on RetroPie v4.4 and Raspberry Pi 3 Model B+

fraisdos125

Good tutorial, pulseaudio works very good with retropie/kodi.
Just one point to add to the tutorial. The following modification is needed in order to avoid sound crackling and speed issues:

sudo vim /etc/pulse/default.pa
change "load-module module-udev-detect" to "load-module module-udev-detect tsched=0"

This will switch the audio scheduling from timer-based to the traditional, interrupt-driven approach. Which is the one will is needed at least for the PI 3b+.

Sound quality can even by increase with the option Audio Resampling to highest quality.

@machile I have done this on the pi 4. It has broken the hdmi audio completely, stuttering on everything I do. Any idea how I can roll it back? I have removed everything I added to the files, and Uninstaller pulse.

Hey, working on the rpi 3 b+ and I can’t seem to find /etc/pulse/default.pa. All that is in the /etc/pulse folder is two config files. Please help me.

@DudeLebowski You should copy all the folders that you have installed personally and then reinstall the base software.

@DudeLebowski Did you find another way to connect bluetooth audio?

@dudelebowski Yeah, I'm encountering the same issue after following this guide, where HDMI audio no longer works right. Have you found a solution to this? I'd rather not reinstall, and I guess there's no way to swap between the two freely. Hopefully someone can chime in with advice.

Did you solve it as I have the same error message. Also the bluetooth speaker is connected, but can't get any audio there also with the speaker-test command

Hi.
I followed this tutorial's steps and managed to get my BT speaker working.
The problem was that after reboot, the speaker failed to connect.
After searching the web for a while, I ran across this: https://unix.stackexchange.com/questions/334386/how-to-set-up-automatic-connection-of-bluetooth-headset
Please see the proposed solution.
