My card cost 20US$, so I'd have to spend a lot to get 96, too. I'd like more channels, though.

My laptop has 2 USB3 ports (indicated by blue connectors) and 2 USB2 ports. I have a USB3 ext drive attached to one, the soundcard to the other USB3 port. 

Every time I've tried LXDE, I've been frustrated by difficulties configuring it. And it would freeze even without RT audio. Glad you've had good luck with it.

I don't remember what background services XFCE installs by default.
