The buzzing in your ears is tennitus (sp). I have it and it is very annoying. That is not what May is hearing, I am sure, as it would not stop with the MUTE button on the TV. I wish it would. Can't help with the cable problem, never heard of it before, but my SIL worked for them for a Long time, I'll ask him when I can. As for the Tennitus, white noise at night helps. Other than that, I've not found anything that helps!! Let me know if you do.
