[bluez 5.68] Bluetooth audio: Random cuts and no audio

On bluez 5.68. Random cuts and no audio while changing volume or playing from mpv and firefox at the same time. Linux Studio plugins also stops working while playing audio over bluetooth.

[ainz@archlinux ~]$ inxi -Ea 
Bluetooth:
  Device-1: Cambridge Silicon Radio Bluetooth Dongle (HCI mode) driver: btusb
    v: 0.8 type: USB rev: 2.0 speed: 12 Mb/s lanes: 1 mode: 1.1 bus-ID: 3-4:2
    chip-ID: 0a12:0001 class-ID: e001
  Report: rfkill ID: hci0 rfk-id: 0 state: up address: see --recommends

Using linux-lts, pipewire.

Tried:

  • Different codecs like: AAC, SBC, LDAC.
  • Downgrading bluez bluez-libs bluez-utils back to 5.66-1.
  • Downgrading linux-firmware to 20230404.2e92a49f-1. No luck.

Is anybody having this annoying problem?
