MakeMKV and LPCM Audio

This post is to share some information and the solution to the problems I was having with MakeMKV and Blu-rays with LPCM audio. When remuxing Blu-rays containing LPCM audio with MakeMKV, I would not be able to playback the LPCM audio track using anything, including VLC on PC, Popcorn Hour c200, Boxee Box, etc. MakeMKV sets the Codec ID to "A_MS/ACM" which is a very uncommon codec. To solve this problem, open MKVmerge GUI, and go to File -> Header Editor. Then go to File -> Open and browse to your MKV. Scroll down to the audio track that contains the LPCM audio and change the Codec ID from "A_MS/ACM" to "A_PCM/INT/LIT". Then File -> Save. Your MKV will now contain an LPCM audio track that should be compatible with any software or hardware capable of playing MKV files... Hope this helps...

I have not had a problem with LPCM on the Boxee Box, but the Popbox V8 won't play the LPCM. I wonder if this is why?

It is most likely your problem... Test it out and let me know... There is no need for a remux, only takes a second to make the change..

Lush78, You da man! Awesome resolved my issue on the Popbox V8!!! No one on the Popbox forum even replied that the Popbox was capable of passing PCM through, much less had a solution. I think I will reply to my own thread on the popbox forum with a link to here. Thanks much.
