Hi

Is there a way to configure it so I don’t have to change audio source from stereo to f.eks Dolby Digital?

I don’t understand that.   Passthrough is passthrough.  It doesn’t do anything to the audio – it doesn’t downmix anything.

The only exception I can think of to this is multichannel AAC, which is not supported.

Dolby Digital, though, as you mentioned in your first post, is passed through untouched – multichannel or otherwise.

The only thing I can think of is that you have your AVR or receiver configured incorrectly.

Please post the full TEXT output of MEDIAINFO for a file you’re having an issue with.

The video file have two audio tracks, one aac and one Dolby Digital that is sent to receiver via passthrough.

The passthrough is working, it is just that I would perfer it to be default.

I think you’re confused.   Passthrough setting is permanent.   If you have it set to “Digital Passthrough” that’s exactly what it’ll do.

But unless your receiver supports AAC decoding, then the WD is going to change it to 2-channel PCM.

If you want Dolby Digital to always be sent instead, then you need to remux the file and set Track 2 to be Track 1.

Not so much confused, but I thought I could set it to be the passthrough even if it is in second channel.

If I don’t remember wrong I think that is what happend on an earlier firmware,

Do you have a recommendation for a windows program that can remux my files?

You’re not understanding what passthrough means.

When you configure the audio mode to “Digital Passthrough via HDMI Only”, it passes through whatever your active audio track is.  Only ONE audio channel can be processed or passed through at a time.

It’s not possible for any device to send multiple audio streams simultaneously via the HDMI, Optical, or audio outputs.   The receiver would have no idea what to do with multiple streams.

No firmware has changed this behavior…  

I’m not familiar with tools that remux M4V files.   But if you have MKV files, MKVmerge is the way to go.

I remember now, I had an apple tv before the wd tv, and when I used that I could set Dolby track as default.

I do understand passtrough, and my original question was if I could set track 2 as default. But I guess there is no configuration for the video player. So I either have to remux all videos or just switch when starting a video.

Which was not at all clear from this post’s subject nor from your explanation. Now that this is clear: no, you need to remux whatever audio you want to be the first track in the file.

I have found a tool that can reorder the audio tracks in m4v/mp4 files. MkvToMp4, it can also be used to inject info about movie.
