Hello - Around the 11th of May I began getting the red slash after 2yrs of using the B/T ear buds on private listening (EVERYTHING BELOW IS AN ISSUE WITH PRIVATE LISTENING, WHEN ON AN OUT OF NETWORKED BIG APP NAME, WHERE AUDIO HAS ALWAYS PLAYED THROUGH BLUETOOTH NOW INSTANTLY PUTS A RED SLASH w/ what I believe Is the gen 2 Google Chromecast hockey puck. Plugged into each HDMI as per test for hardware (no difference), on a TCL cheaper but decent TV. The chrome cast is not USB powered back to the TV itself, but in a receptacle. If I use the app's as i.e. Netflix, Amazon, ECT, everything is fine. I have unpaired, uninstalled, reinstalled apps, then the windows thing happened. Lordy. I'm hung up on what am I missing. Anything outside 3rd party. I.E a ball game through a 3rd party site is being blocked. I went all the way back to reinstalling Windows because I was adjusting everything. I know it's something stupid. BUT WHAT LOLO, I'm going mad, yet I can listen through 'cast-sources', 'Desktop' but where did tab go. I can't figure out what/where could be a security setting that is blocking audio for 3rd party sites. When I cast, the section sources 'tab' doesn't have audio out of my B/T ear buds, but yes the TV does play the audio. Under sources 'desktop' audio plays video/audio, and through B/T, INSTANTLY the red slash appears right away. NOW, if I cast, choose desktop, my ear buds will play, but you know where it's coming from, the laptop. I never ran into this red slash before through private listening. Any help is greatly appreciated.
