well, it's not actually myth that doesn't support HD passthrough, I
don't know of a system on linux supporting it yet, it's also a
hardware issue.

In theory, there could be differences. EAC3 or DTS-HD aren't limited
to 8 channels. Dolby also supports things like "sound elevation" which
would be lost during LPCM conversion.

In practice, it will be inaudible, and you'll only see 7.1 audio tracks.
