Anyone tried new Wasapi with a laptop running Win7 ?

WASAPI works great on my machine, but for Live 8 I still need ASIO4ALL.

 
i think this is now the clincher - maintaining a single drivers configs, versus two

I would be very surprised if asio4all came anywhere near wasapi under Windows 10 for latency. Microsoft have made many Improvements to wasapi.

hence the question! they both go via wdm

For me the big deal with WASAPI is I no longer need to carry around an ASIO interface for my laptop, and can use the internal sound chip. I've done RTL tests and have gotten as low as 4-5 ms to 7-8 ms. I haven't yet figured out what I did to get it down to 4-5 ms but even 7-8 ms is sooooo much less than MME (which I believe stands for Multi Media Excrement).
 
I can't compare to ASIO4ALL because no matter what latency I choose, after a few minutes it starts crackling and going nuts. Interestingly, often the fix is to set the latency much lower, but it still ends up going nuts after a couple minutes.
 
You might want to stick with ASIO4ALL for now since it does work on your system, AFAIK SONAR is the only program that takes advantage of the new driver model. I'm sure other companies will follow (and given how many laptoppers use Live, I would assume it's in their product plans) but who knows how long that will take.

It's only meant for Win 10, at least that's what I read

I think it may be you only get the full advantages with Windows 10. Maybe someone can try it on 7 or 8 and clue us in.

wasapi was introduced in vista(!) but the new stuff is win10 only

I tested it on 3 Windows 7 machines and it's no better than WDM mode. 
I had a thread here somewhere with screenshots showing my loopback tests. On W7 it's late by more than a 1/16 note, W 10 it was only late by a 1/64th. ( note: ASIO mode on all machines was right on)  
Works fine for playback but so does WDM or even MME mode. 
So, it works but there's no improvement unless you upgrade to W 10 which is what I just did with one computer.  
On windows 7 you can still use it if your doing a lot of stuff like playback and editing, but be aware if you overdub audio it will be out of sync. You'll need to use manual offset to fix it. 
It's best use is for working with on board audio, Some interfaces will not support it and there's no point using it instead of supplied ASIO drivers anyhow. 

I'll be that "Wasabi exclusive mode" goes good on sushi...
