Hi @timjpreston
Have you tried a different HDMI cable or different port on the TV to see if this helps?
Also please can you try and change the V6 settings by pressing HOME on the remote, then the following
Help & Settings > Settings> Audio> Dolby Digital> Dolby Digital to PCM
I often had sound drop outs on one of my V6 boxes until I changed it to Dolby Digital to PCM
