Also forgot why are people not just using the a2dp LDAC Windows driver software which I believe can work on BT adapters connected to the PC or laptop and just use that?

It was mentioned to me on the XM5 thread by another headfier here, possible its something new since this thread is bit older and out dated with information.

Any kind of dongle that can also serve as a bluetooth transmitter ?

Not quite dongle size but might be worth looking at the 1Mii, Avantree and Fiio products, plenty on amazon and ebay usually. Also aliexpress has lots of them in various sizes and boxes but if they work well is another thing.

Some of their products are reviewed and mention on headfi often I have also reviewed a few myself see my link in the signature, so its worth checking reviews out they can be hit and miss with bugs though, firmware support and if their features actually work.

With amazon you may have a better return policy so can trial it out at least.
