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.

Understanding Dolby TrueHD and EAC-3

Dolby TrueHD is a lossless audio codec that delivers high-definition sound, commonly found in Blu-ray discs and high-quality video files. However, not all devices support TrueHD decoding, which can lead to playback issues.

EAC-3, also known as Dolby Digital Plus, is a widely supported audio format that offers high-quality sound and is compatible with a broader range of devices.

Here's a brief comparison:

Feature	Dolby TrueHD	EAC-3 (Dolby Digital Plus)
Audio Quality	Lossless, studio-quality sound	High-quality, lossy compression
Bitrate	Up to 18 Mbps	256 kbps to 6 Mbps
Channel Support	Up to 16 channels	Up to 15.1 channels
Compatibility	Limited to advanced systems	Widely compatible
Use Case	Blu-ray, home theaters	Streaming, TV, mobile devices
File Size	Larger	Smaller
