Volume controls aren't working

  • When I start my Wetek Play 2 volume is stuck on 100% and changing it doesn't work. The only way that works is via Yatse app by pressing volume controls on my phone. Yatse on-screen volume controls aren't working either. Restarting the device does solve the problem, but it reappears after turning the device off and on again.

    The same problem has been mentioned here, but so far no resolution.

    Libreelec version: 8.2.1

    Hardware used: Wetek Play 2, Xtreamer AirMouse 2, LG TV 32LH3000 connected via HDMI, passthrough is disabled.
