My Denon AVR has started having trouble decoding TV3's 5.1 freeview sound. Everything is fine when TV3 transmit full HD/5.1 source material. But, when the source is not 5.1 (advertisment breaks and most material) the result is silence. Switching to the 2ch AAC sound channel produces normal results but it is incovenient to be swtching back and forth. Strangely the Denon displays the didgital source as 6.1 not 5.1. I'n not sure when this started happening except that it is within the last month. Has TV3 changed their sound format in some way?
Any help appreciated.
