Has any one else had this audio issue with a VP30 following an upgrade to firmware 1.1? Im using an Arcam AV9 processor and a Sky HD box with the VP30. I have also used another Freeview STBs with the same results.
Basically, when I switch from one channel broadcasting in PCM to another broadcasting PCM the sound coming though my speakers is suddenly very loud, distorted, and is overlaid with what seems like white noise. Once affected like this I have to turn my AV processor off and back on again. This corrects the problem until I change channels again. This issue does not happen when I switch between Dolby Digital channels.
I have tried switching back to firmware 1.07 and the problem disappears, but returns after reloading 1.1.
Im not sure if it is relevant, but I have noticed that, when I leave the Info Pane visible as I change between PCM based channels, the sound format reported by the VP30 momentarily changes from PCM to DTS and then back to PCM again. I am wondering if my AV9 processor is attempting to switch between PCM and DTS, as instructed by the VP30, and then staying in DTS mode even though the channel is now outputting PCM, perhaps because it cant react quickly enough to format changes that sudden.
I have also noticed that if I dont use the VP30 for audio switching the Info Pane reports that the audio input is DTS even though there is nothing there at all.
At the moment, in order to get round this problem I am routing the sound from the Satellite Receiver directly to my AV9 processor, without any problems. However I would obviously prefer to use the VP30 for audio as well as video switching.
I have reported the issue to both Arcam and DVDO. So far Arcam have been helpful, spending time on the phone talking me through changing settings in the AV9 Engineers menu, unfortunately with no luck. I have had little feedback from DVDO other than they are looking into it.
Any ideas?
Cheers, Roman
