[SOLVED]Bluetooth audio choppy (Unexpected continuation frame (len 0))

rvf16 · 2019-08-26 14:19:08

Hello

After update of system on 2019-08-25, audio via Logitech BT adapter became choppy.
Sound starts choppy, continues in this manner for 10s then stabilizes for 10s and this is repeated endlessly.
Sound plays normally using the laptop's speakers or the audio out to my ear phones.

I have an earlier copy (1-2 months old) of this system on an external usb disk partition which is working properly so hardware seems good.
I haven't changed any bluetooth,pulseaudio settings lately.
Probably latest update broke something.

Any help is welcome.
Thank you in advance.

After full update of system on 2019-08-30 16:00:00 (5.2.11-arch1-1-ARCH), audio via bluetooth device is working properly.
Thanks to the developers for fixing this.
