Hi guys, I was wondering if anyone with audio knowledge could help me. I have a Creative Sound Blaster Z + Logitech Z5500 5.1 speaker system - connected by analogue in 6 channel mode, i get 5.1 sound in Battlefield 5 - all good there. However, over SPDIF (Toslink) digital connection, I just get stereo, and control unit for my speakers doesn't light up with the Dolby Digital logo i.e. no 5.1 sound. Does Battlefield 5 not produce a Dolby Digital audio stream? If not, I'm guessing that's why I only get stereo if I connect with SPDIF, but I get surround sound if I connect by analogue. Annoying because I suffer from some EMI interference on my analogue connection (a high pitched background noise), which I am going to have to attempt to troubleshoot. It's annoying when my speakers are on and I'm not playing any sound, it's not too noticeable when I am playing sound. Many thanks!
