Bluetooth Sound Fragmented

Hi all. This is a cross post from Pine Forums. Still going with this one.
Hardware is Quartz64. OS is Manjaro with latest updates.

Manjaro OS is booting and working remarkably well on Quartz64 model B. As a desktop I find the system is very usable, albeit a bit slow in a graphics intensive browser.

Anyway I wanted to test bluetooth connectivity and performance. Both bluetooth devices (speakers)were detected by Quartz and both connected to Manjaro/Quartz64. Unfortunately the sound is jittery and fragmented.

Any ideas on how to address this? Bluetooth is working, but the sound is jumpy. Does this imply that the firmware is working?

The log below refers to an absent firmware patch file which I find confusing.

Update. I have come across a post from June (Pine64 forum) that talks about stuttering in Bluetooth. So this matter is old. While googling this matter, I came across Ubuntu users on other forums who describe in some detail what to try. I will give this a go.

Hi,

If you come across a solution I would appreciate an update, for I have just moved my daughter’s (x86 PC) from Mint to Manjaro, and she now complaints about bluetooth sound fragmentation in her BT headphones, that she didn’t complain about with Mint.

(Si it seems the issue is not ARM specific)
