Just in case anyone can help I thought I'd ask

I have a problem since moving with the telly

TV works fine (analogue) but I have a problem with sound with anything plugged in using HDMI - it's really odd. DVD player plays DVD films with no problems but CDs have a problem where the sound cuts out every 2 minutes approximately for about 2 seconds.
PS3 has a similar problem - games play without problem but DVDs have the same sound cut out as CDs (at same times too).
I've tried changing everything - changing lead to a different HDMI input doesn't solve it, changing HDMI lead doesn't help and both problems don't happen if connected to a different tv [

Any suggestions might just help me keep what sanity I have left, thanks
