I’m reviving this old thread to ask a follow-up question. I also have a BV7-32 MKIII with DVI-input, though with the standard Beolab 7.1 speaker. I’m trying to connect the Beovision to my modern HDMI set top box, which also has a optical digital audio out socket. Getting the picture through with a HDMI to DVI adapter works just fine. For the audio, I’ve tried a HDMI audio extractor from a different brand than the ones suggested on this forum, however this didn’t work (the picture becomes very unstable or drops off completely, and there is no audio despite following the instructions here on how to connect to the Beovision’s analogue L-R audio input sockets). I also tried the optical digital out route, getting an audio converter from Amazon to convert the optical audio out signal from the set top box to coaxial in order to connect to one of the Beovision’s digital audio in sockets. I made the corresponding changes in the TV’s settings, i.e. changing the audio input from none to A1-A4 for the AV4 on the Beovision. But there is no sound at all. I’ve tried all the different audio in sockets and the audio converter seems to be working (though I’m not able to test this with another device).
Any advice? I understand that not all HDMI audio extractors work so I could try to get one recommended here to see if this works better. But I don’t really understand why using the digital audio in sockets on the Beovision doesn’t work (this is even mentioned in the reference book as an option to use with the AV4). I suppose the converter could be broken but I think it’s unlikely. Because converting a signal from optical audio out to coaxial digital audio out shouldn’t affect the Beovision’s ability to receive the signal, right? I suppose I could also try to get a converter from digital audio to analogue, but that would defeat the purpose of using digital audio (surround sound, etc.).
