Hey guys,

I have a problem. I'm trying to extract 96kHz audio from an AVCHD DTS-MA 5.1 Audio disc using Audiomuxer. I know the disc is 96/24. However, when I select the MPLS file in Audiomuxer, it says that the track is only 48/24:

I have ArcSoft Audio Decoder installed and restarted my computer after installing it, so I should be able to extract the stream in 96kHz:

Checking the extracted mono wav files with Spek afterwards confirms that they are only 48kHz. How can I make audiomuxer extract a 96kHz stream?

Strange indeed. Are you sure it is really 24/96?
To be sure, download and install MediaInfo. Go now to the BDMV/STREAM folder and check the m2ts files by right-clicking the file and then to use MediaInfo on the file.

The Audio section should look a bit like the one here below if the DTSMA is 96kHz with a 48kHz core.

Should that be the case, PM me and we will try to manage it off-line.
