I have just unpacked and set up my UK spec Chromecast - the cast is fine, it connects and the video as clear - however the audio is like a very high pitched robotic whistle, you can make out that there are pitch changes in the whistle when people talk and music is playing, but you cannot make out anything other than that. And its hurts my ears.
I have tried it on my HTC One, Nexus 10, using the EE router, the extender, BBC iPlayer and YouTube - same everywhere. I have unplugged and pressed the little button. Nothing helps.
Can someone help me??
I am using Android 4.4, my routers are EE Brightbox (by Astoria Networks) with a Netgear WN2000RPT range extender, and my TV is an Elonex LNXTY 37F2.
Thanks in advance!
