Does Intel AC 7265 wifi support aptx?   Which devices support aptx lossless?

Does all bluetooth 4.0 include aptx support? I have bluetooth 4.0 via Intel AC 7260 wifi card, but it says nowhere that it supports aptx.   If I don't have aptx support, is there another PCI half mini express card with ac wifi and bluetooth aptx available?

I want to stream audio from my computer/mobile to my stereo which only has analog (rca) input. Currently I use a USB connected NuForce Icon uDAC 2 which works great, except for the usb cable between my computer and stereo. Is there a way to stream sound by wifi to a usb dongle which is connected...
