i have samsung tv that connected to beam 2 by HDMI to Earc until yesterday every thing work fine.
after the update to 15.8 the beam refuses to connect to the tv. i talk with the support and we tried everything. the only way to get the beam to connect is unplug the power cable and plug it back every time i turn my tv this is the only way. since yesterday that what i do every time i turn my tv.
its a nightmare sonos have to fix this issue.
