I use a WiiM AMP connected to my TV via HDMI ARC. It used to work fine but over the last couple of weeks (or even months?) there are more and more the sound turns off after pausing a movie for a while (like 15 minutes). When I continue playing then there is no sound, yet the WiiM AMP is still on and the selected input is still HDMI ARC. When I try to change the volume then I change is indicated on the TV screen (which also shows the volume is controlled on the WiiM) but there is still no sound produced. The only reliable way to fix this issue is by swithcing the WiiM'sinput channel to Line In and switching back to HDMI ARC. But this is quite annoying.
Is there any setting that keeps putting the WiiM into some sleep state or something like this?
Maybe worth to mention my setup:
There is a Fire TV stick in my TV (its remote control will turn the TV on and off).
A 10+ years old Samsung TV connected to the Wiim AMP via HDMI ARC. The WiiM AMP will be automatically switched on with the TV.
Do you have an idea how to fix this issue?
