I've been working on this for 2 days now with no success. I am on Windows 10 and audio is going from my pc to Yamaha Aventage RX-A2030 via HDMI. I have a gigabyte GA-Z77Z-UD5H motherboard. I am using the file found here for testing: Demolandia.net My windows audio setup is correct because it works beautifully with the awful Windows Media Player but not with VLC. I have tried everything I can in both simple and advanced settings but still only 2 channels. I've tried every output module, I've tried forcing Dolby detection, I've tried disabling audio resampler, I've enabled HDMI passthrough (this got DTS and Dolby Digital + working). Nothing works for Dolby TrueHD. Does VLC not support this surround mode when WMP does? Can anyone else get 7.1 output from that Demolandia file on VLC?
