Q: "I have some .mkv files with Dolby TrueHD tracks which I would like to serve to a client which does support TrueHD, is it possible to convert TrueHD to the next-best EAC-3 or AC3 supported by the client?"

A: Well, you're not alone. Despite the fact that the Dolby TrueHD is an advanced lossless surround audio codec based on Meridian Lossless Packing (MLP format) that can deliver top-quality audio and provide the most authentic surround sound experience, you have to admit that not every device is capable of TrueHD audio decoding. That's the reason why "unsupported audio format" error occurs or there is no audio when playing movies.

Rather than upgrading equipment or waiting for the device firmware update, you can fix this problem by converting TrueHD audio to its predecessor AC3 since AC3 decoding is widely supported by most software and hardware. Next, I'll expound how to convert TrueHD to AC3 in a video file.
