I have been experiencing loud indiscriminate screeching when I have the audio outputting to optical.
It doesn't happen all the time. It seems to only happen upon boot-up or coming out of sleep mode. Regardless if I have it defaulted to optical or have it set to HDMI than switch to optical.
When it happens the only things that seems to fix it is restarting the PC than its just fine. And again it doesn't do it all the time just rarely.
I contacted ASRock about it and they didn't seem to want to bother with figuring it out. And just send a RMA. But, if I can fix it I would prefer that route. As I am not keen on having to tear down the PC and wait for a replacement board.
So, I thought I would check with you all just in case someone might have a idea of the cause or a fix.
The SR5009 supports 4k/60 video pass through so why is your chain not just HDMI from pc to receiver to display?
