TrueHD audio being backed up as 5.1 only with Handbrake
"I'm running MakeMKV v1.7.10. Working to digitize blu-ray collections. I had no. I have run into a rather odd problem. All the DTS-MA and Dolby TrueHD 7.1 audio streams are being saved as 5.1. I've been transcoding with Handbrake after the MKV backup from the discs and it sees only 5.1 tracks. Also, when playing back the un-transcoded files in either XBMC or VLC they both show only 5.1 DTS-MA or TrueHD audio streams for any that should be 7.1. This isn't a huge problem since I only have a 5.1 system, but I like backing up the original audio tracks in case I do get a 7.1 system in the future."
Handbrake allows for 2 types of output files -MP4 and MKV. Only the MKV allows for DTS-HD passthrough. The problem is that Handbrake can not "auto-passthrough"a TrueHD. So if you want to compress a TrueHD file with Handbrake, you will need to use the Dobly AC3 Passthrough or similar. How to get a TrueHD Passthrough from Blu-ray movies?
