Pulseaudio A2DP Bluetooth signal quality [poor]

Does anyone know if this Pulseaudio bug was ever patched by the devs of Pulseaudio or alternatively the Manjaro team?

Using Bluetooth headphones, I'm experiencing similar signal issues; stutter, delays and pausing, limited range and rather poor audio quality.

Bluetooth works fine with an Android phone and an ipad, good audio quality and range, which rules out the headphones. Also tested on a LinuxMint laptop (which I assume uses the 2018 Ubuntu patch) and the connection was better, albeit not as good as on the phone or ipad.

If anyone knows about this (or how to troubleshoot the darn thing) I’d be grateful for your thoughts!


I'm guessing your using a combo wifi-bluetooth chip.
Please post the output of the following command:

hwinfo --netcard --wlan --bluetooth | grep -Ei "model\:|driver\:|status\:|cmd\:|file\:|detected\:" | grep -v "Config Status" 

Hi tbg, that's right. Here we go:

$ hwinfo --netcard --wlan --bluetooth | grep -Ei "model\:|driver\:|status\:|cmd\:|file\:|detected\:" | g
rep -v "Config Status"

Bluetooth and 2,4 GHz Wi-Fi work on the same bandwidth. The 2.4 GHz Wifi band and bluetooth spectrum's have a great deal of overlap and can interfere with each other. Try disabling the 2.4 GHz band on your wireless router. Use your router in only the 5 GHz mode and see if your bluetooth behavior improves.

ArchWiki documentation:



Instructions for installing Broadcom Bluetooth firmware:

Not sure why, but 5 GHz was unavailable from my router’s cpanel so I instead powered it off and tested. No improvement, however.

Installing the broadcom-bt-firmware. [edit] dmesg doesn't give an output that identifies the needed firmware package, for example BCM20703A1-0a5c-6410.hc.

^^^ This is your chips ID if you want to try installing the firmware.

Ah, I understand. I was unsure because the winterheart/broadcom-bt- repo doesn’t support that chipset.

I thought maybe I'd done something wrong. Sorry for missing the obvious, I do appreciate you taking the time.
