Raspberry Pi 4, Bluetooth issue with audio devices

Hi there,

I am using Xfce ARM 20.08 on RPI 4 using FW version: Thu Apr 16 05:11:26 PM UTC 2020 (1587057086).

The connection is on and off and sometimes when I connect (25% of the times ) the audio is cracking and shuttering.

But this is only with Manjaro, I tried with other distros like Ubuntu and Kali and the audio working great.

What I need to fix to get the audio working with Manjaro?

I do not have a sound bluetooth device so can not test. Can you enable the device with Puldeaudio volume control? You can also try changing the value for snd-bcm2835.enable_compat_alsa=0 to snd-bcm2835.enable_compat_alsa=1 and reboot to see if it helps.

No changes…still choppy sound. Tried Raspberry Pi OS, and of course not a problem, even better of Kali and Ubuntu, not choppy at all.

What info I can capture from it and see why I have issue in Manjaro?

Same issue with KDE on my Raspberry 4 8GB with bluetooth speakers.
Sound is ok with headphone connected to pin 3.5 Audio.

Any ideas to solve my issue.
My bluetooth speakers work well with Ubuntu-mate or windows 10

Apologies for my previous post (queued for deletion), as it was misguiding and false.
When I was removing alsa configuration, clear sound was working fine, but via the HDMI, not
bluetooth. But I have a solution for you. It was working on Archlinux ARM and it is working on
manjaro :slight_smile:

  1. Get rid of brcm43438.service.
    systemctl stop brcm43438.service
    systemctl disable brcm43438.service

  2. Install and enable community/brcm-patchram-plus
    pacman -S community/brcm-patchram-plus
    systemctl enable attach-bluetooth.service

  3. Reboot

Now bluetooth audio works fine.
