Q: "When I use MakeMKV to rip a disc, I get an .mkv movie file with a TrueHD 7.1 audio track. How can I transcode TrueHD to EAC3 as my receiver is only capable of decoding E-AC-3 5.1 audio?"

A: Actually, the Dolby TrueHD audio track is typically saved in video files with .mkv, .mp4, .m2ts or .evo filename extension. Under normal circumstances, almost every video file with TrueHD audio has an additional Dolby EAC-3 as the second track, you just switch it to EAC-3 or disable TrueHD option in your device to play the video with sound normally.

But there is always an exception to every rule. If the video only has a single TrueHD audio track or the solution doesn't work, I'll provide a surefire workaround below.
