I just bought a Aspire E5-571G-583R and I'm trying to get 5.1 sound from it. I've connected the laptop HDMI to my home theatre system which supports both Dolby Digital and DTS, not working. I've also tried to my LG LED-TV which supports Dolby Digital, that's also a no go. I've installed the latest Realtek drivers from your download pages (188.8.131.5250). The problem, as far as I can tell, is that it uses the Intel display sound driver instead of Realtek HD sound driver on the HDMI port. I have tried to change the driver on the HDMI device to Realtek but then I got the win 8.1 version of the BoD. So I guess I've two questions: 1. Is it possible to force the Realtek driver on the HDMI in order to get 5.1 sound? 2. If not, how do I get 5.1 sound from the laptop?
