Had new V6 Box installed a week ago. Volume is way lower than Freeview Play & Apps on Smart TV. Recordings and some channels have drifting volume (up & down continually). The box audio output is set to PCM & the TV is set to auto. 8-10 times in the past week we have been watching recordings and had the purple screen of death. The only way to restart it is to unplug the system as the remote freezes. Also when stopping recordings we are watching, the remote freezes and we get a continual green flashing light on the remote itself. Not happy at all with the new box as yet. Equipment is as follows.

Thanks for posting and I'm sorry to learn you're experiencing problems with your V6 box.
What I would like to do here is to send out one of our engineers to check things over so I'm just going to send you a private message with appointment times which you will find if you click on the purple envelope at the top right of the screen.
