AC3: Specified channel layout '7.1' is not supported

Posted: Sun Dec 07, 2014 10:36 pm

I normally always succeeded in ripping my BluRays to MKV with a additional AC3 track. However, I now have a BluRay that fails immediately.
Is it expected that 7.1 audio is not able to be encoded to AC3?

Unfortunately I just had upgraded my MakeMKV to the 1.9 version, so I don't know for sure it's caused by this upgrade. I did however try with a older one that normally worked, but that one also failed.

It seems that AC3 only supports 5.1

I have added a 5.1 audiomix setting to the DTSHDMA-multi tracksetting, and now it works ok.

I have added a 5.1 audiomix setting to the DTSHDMA-multi tracksetting, and now it works ok.
Please note that MakeMKV has a known limitation - down-mix is added unconditionally. So if you ever get a stereo DTS-HD track, it will be also "up-mixed" to 5.1 . This is planned to be fixed via ability to specify down-mix depending on source channel layout.

I just had the same issue with 7.1. - The proposed audio mix addition (fix) does not work in my case (was unknown) - Can this be fixed differently now ?
