WD Live TV selects 2.0 audio as the default

The WD Live TV selects 2.0 audio as the default. The surround sound is in my source file because I can select it in the options menu and it plays just fine once I do but how can I tell it to select the surround sound track as the default? I thought the Auto setting was supposed to do that.

The WDTV will always play track #1 by default.

If you want your surround tracks to be played “by default,” then you need to remux the files so the surround tracks are the first.
