Question on what the right settings are for Windows 10 sample rates.

So in Control Panel sound settings the default sample rate is typically 48khz. I'm using an external audio interface (Motu) to route audio to my speakers or headphones, and it's setup as the primary audio device in windows. The Motu I can also set to its own internal sample rate (currently at 96khz, can go up to 192khz).

Now, when I play back audio in foobar2000, what sample rate will it actually play at (what do I hear through my speakers)? Sample rate of the source file (ie 44.1khz/16bit)? Upsampled to 48khz because of windows setting? Or upsampled to 96khz because of Motu internal clock?

How can I ensure that it always plays at the source file sample rate?

If you do "nothing", all files you play will be resampled to the rate as set in the Win Audio PAnel

As you are using Foobar and assuming the Motu is over USB, you can use WASAPI in exclusive mode.
This will bypass all of the Win audio and talk straight to the audio device.

Hence all audio will send in its native sample rate to the Motu

Don't know if the Motu allows for automatic sample rate switching as well.

In wasapi event mode I kept getting errors such as sample rate not recognized or something like that, and in wasapi push I'd get weird stuttering / skipping. In ASIO mode it works fine and does change sample rate each time, though each time there is a delay and I need to restart playback of the file. So none of these work perfectly. You'd think a pro audio interface wouldn't have issues.
