If you want to find out real capabilities of your USB sound card, you can use any linux computer (just boot a live CD, e.g. ubuntu, or USB stick), plug your DAC and take a look at file /proc/asound/cardX/stream0, where X is number of your soundcard card (most likely 1 as 0 will be the integrated soundcard).
My multichannel card based on CM106 lists the following possible configurations (alt settings):

Your card based on Tenor will report different capabilities. Based on requirements from the playback chain the USB driver should switch the card to the best fitting altset. At least that is how it works in linux.
