PC into TV - sound feedback (frequency?)

[faxfan]

Hi All,

I'm putting a PC (Navida GPU, HDMI) into my TV and everything works in terms of resolution etc. But when I run a game or have a browser of predominantly one i.e. white. I get terrible feedback (sometime quite a lot sometimes very little buy always there) - it's like a frequency feedback noise, if that makes sense?

Full setup

PC (Nvidia Titan X - Series 9) -> Sony X93 HDMI port -> HDMI ARC -> Arcam AVR 550
OR
PC (Nvidia Titan X - Series 9) -> Arcam AVR 550

Tried -

-> Different cables / ports
-> Different frequencies 24,50,60 - the TV and PC appear to sync fine
-> Colour spaces RGB / YBr etc. - again TV and PC appear to sync fine

Any ideas?

I don't know what you mean by that,

But if the sound occassionally stalls/stutters can be a interrupts not being serviced on computer due to driver problems, so called dpc calls - google it , can install latmon. sounds like this
XPS15z Audio Crackle Issue - DPC Latency

Does problem occur during utube or other music playing ?

Have you turned off windows sound effects and given exclusive access to applications that request it, also modifying pcm sample frequency (all of that is under the 'playback devices' menus)

post a recording of what you hear ?

It's really the opposite when sounds are playing i.e. youtube it's fine, it where there is no sounds you get the feedback - though I suspect the feedback is there just can't hear it because of the other sounds.

I'll pop a video up later

Check your enabled devices in sound settings for open microphones or anything that can record and make sure it's muted.
