I run HDMI through a Sony AV amp with Dolby digital decoder. All was working fine but recently the dolby digital signal on BBC HD keeps changing back and forth between Digital 3.2.1 to Digital 2.0 with a resulting step change in volume. Changes happen maybe twice over a 2hr period. Any clues?
Lots of people (including me) have been experiencing volume fluctuations on BBC HD. I'm also going through an AV Receiver but hadn't noticed the change on the amp. Looks like it might be a fault with the BBC, as someone had the same problem using the iPlayer on a PC. I've noticed it for a few weeks but haven't seen an official response from Virgin apart from the usual 'we're looking into it'.
