Chirpping noise
 

I have added 3 new pieces to my system

Marantz AV 8802a
Roku Ultra
LG B6 OLED


The roku was added first and I had no issues with it for two days with the old reciever and TV.

The AVP and TV were added at the same time .

I have noticed a light chirp every 20 minutes to half hour seems to be coming from different speakers intermittently ?

1. I suspect the AVP possibly a capacitor issue?

2. Could it be a cable signal going in and out? We are still not completely recovered from the high winds fron last week...cable service has been sketchy

3. Could it be the TV? the are some judder & blur issues also intermittenly

I lean towards the AVP but was wanting other opinions.

It was the Roku Ultra!!!!!!!!!!!!
