I used to have this problem with the regular WiiM Amp long time ago, but it was fixed with a software update.
Now I switched to WiiM Amp Pro and it has this problem again.
When it's connected to my LG C9 TV via HDMI, and the TV audio output is switched to something other than HDMI, the Amp Pro starts to produce very loud crackling/static clicks and pops until the TV is switched back to the HDMI output.
The HDMI denoising option doesn't resolve this issue, and I don't recall enabling it for the regular WiiM Amp.
 
crackling from the speakers (while operating the electric blinds)

with the wiim amp i had the crackling every time i pressed the blinds switch. since the wiim amp pro the noise from the speakers has almost completely disappeared.

nevertheless i noticed today that when i press the blinds switch the wiim amp pro loses the audio input from the samsung oled (2022) tv (arc). i then have to change the audio source “e.g. internet radio” and back to tv and then it works again.

basically no problem for me but i just want to mention that the problem occurs due to “electrical interferences”.

i'll try connecting the system to a different electrical phase. maybe that will help.
