I agree with you that in theory it should be handled like DTS-HD MA for example.
Every program that is playing audio sends an LPCM stream to the soundcard (except bitstreaming).
The soundcard normaly just makes the DA sampling.
I think if you play an LPCM track from TMT, the route is just the same. The exception however is, that you get it just passed through if the signal matches the settings in the audio card. If not it resamples it. Don't know if you understand what I try to explain but i think thats the reason the xonar control panel is used when plaing LPCM.
Oh I understand what you're saying. It's just that my testing doesn't necessarily correspond with it. See, here's my problem. If I set TMT3 to 7.1, reclock kicks in and all is well. This tells me it's not using the PAP which allows reclock to work with the audio. If I set it to pass through, otoh, reclock NEVER kicks in which tells me it's using the PAP. If we're using the PAP, there is *NEVER* a reason to resample the audio as we're making the assumption that we're bitstreaming and letting the receiver deal with it. IOW, I see this as a severe bug in the Xonar driver tbh. When doing PAP, it should never mess with the sample rate no matter what the Xonar CP says. See my point now?
