Problem with sound via HDMI connection with TV

[WinterBornX]

Hello! I have a rather unusual problem. Currently I am using 2 displays. 1 is in my room a normal LG 23' monitor connected via DVI. And a TV in the other room connected via HDMI. I can watch movies play games etc. w/o any problem on my monitor. But when I try to play a movie or a game on my TV after some time the audio breaks. It sounds like when ur signal is low on the radio.I have to turn off the display switcher via win+p to my monitor then back to the TV to fix it. I tryed everything from reinstaliing the drivers - different combinations of display placement , different hdmi cables. etc.
My current setup is
CPU - a10 -7700k
Ram- 8gb ddr3 1600 mhz
Video- Ati r370 2gb
So .. I have sound on my tv just after some times it starts shuttering, lowering quality . etc. and its really frustrating when trying to watch a movie and restarting it 10 times :S
Oh and I'm using a 39' LG 3D tv

It sounds like some kind of buffer is filling up. Are you using AMD's latest drivers for your card? You might remove and reload them. Any change if you lower the sound quality settings?

Yes I am using the latest amd drivers. I also tryed reinstalling then and reinstalling the OS too.And no changes at all if I mess with the quality. It hapens randomly. It might hapen 10 minutes in to a video or 1h.

Bad HDMI cable?

Tryed 4 other cables. I am currently using a 10 meter cable but I tryed with 2.5-5 meter ones too.
