Thanks for this. It almost does fix it...but just not quite, 24/96 still sounds a very small amount slower than the 16/44. But a huge improvement (almost listenable).
I don't really know how (just a lot deleting and reloading Anamaro drivers..3 hours of messing around with my notebook), but I seem to get the option for Anamaro WASPI drivers:
WASAPI
WASAPI exclusive
Direct Stream
So I chose the 'WASAPI exclusive'. After a lot of listening, initially I thought the 'speed' thing was solved, but I'm now sure it's still not quite right (a very small bit slow). Still a big improvement over ASIO. This just lurched me into another problem: as soon as I do a remote desktop from my ipad, the music switches to local and starts playing on the ipad...can't see why.
Thanks for the pointers. It is something to do with drivers, I'm now sure.
Yes, I've managed to do this. It's a little clunky but it works as you said.
Next weekend I'll try Audirvana see if that helps. (I can't take any more messing around with software untill then).
