Mezzmo was working just fine for years then 3 months ago the sound stopped working and i got the error "501: Action SetVolume Failed"
i upgraded to version 6.0.6.0 and the problem persists.
my pc and TV are on the same network and the video works just fine, which is pointless without any sound.
Windows 10 version 21H2 19044.1415
TV - Sony Bravia KDL-40EX503 set to accept in media devices

anyone got any ideas what is causing this?
