Sound is cracks and pops for smart tv function sometimes...
Hey guys, let me start by saying thank you for all the great info on this forum. Also before getting my head bitten off I did use the search tool for this issue and only found one about a vizio sound bar that is a different issue, if this was answered somewhere else I'm sorry.
First my set up looks like this; I have a 65KS8500, Harman Kardon AVR354, PS4, streaming box, and cable (Non-HD). In terms of wiring the PS4 goes into the One Connect box with HDMI and then I have a optical cable running down to the AVR for sound. The AVR has a HDMI Out running to the One Connect. Then I have cable box and streaming box hooked up to the AVR (The AVR only does 720p up-scaled to 1080p which doesn't matter for the streaming box or cable, but that is why the PS4 is connected straight to the TV). The AVR also doesn't have a HDMI ARC Out-put, hence why I have it set up through optical.
So now for the issue. When I us the PS4 audio sounds great, but when I use the smart TV apps everything is cracking and static (highly distorted). I have the AVR input set to gaming which is set up to us optical for audio and both expert sound settings set to PCM. Now the odd part. If I start my PS4 (leave it running or shut it off immediately) all of the smart TV apps sound crystal clear. As soon as I switch inputs on the TV it starts cracking, even if I go back to the game input on TV (This whole time I'm not changing input on the AVR). So as long as the PS4 runs first and I don't mess with inputs, everything sounds good. Is anyone able to explain whats going on or have a solution?
Also short follow-up. Can I use the TV's HDMI ARC to send audio directly to a AVR HDMI Input instead of optical?
Thank you for any help.
