Maybe if you went back to an earlier backup just before you installed the asio4all. That might help.

Brutal. Yeah, try to return it and get something that uses true ASIO. I find it surprising any good hardware company would release an interface without ASIO support these days... and AKAI is a decent company as far as I know. I'd kind of like to get some of their MIDI controllers.
 
I've had nothing but success with my Focusrite Scarlett interface and for 140 pounds (sorry I do not have a pound symbol on my keyboard) I think you could get an 8i6. At the very least you can get a 2i6 (which last time I checked goes for about $150 USD or less).
 
ASIO4ALL is an interesting and helpful tool in a pinch. I've used it to get much better results when using onboard soundcards for just goofing around but it is no match for a good interface with proper ASIO drivers.

i've used asio4all for years, multiple interfaces, multiple os's, go figure... but the op needs to contact akai, as they recommend using it and it's not working

I agree with Beepster. ASIO4ALL has its place and can work wonders for the performance of onboard sound systems with SONAR when needed in a pinch, traveling with a laptop, etc. But no external audio interface worthy of the name should need it.

Very frustrating Recomponent123! I notice there is a guy on the thread below who claims he is getting great results with the Akai. Might be worth asking him what driver he is using:

Once again thanks...I haven't totally given up just yet.

Also this is happening...

On opening Sonar 7 the audio output in the Akai audio panel does seem open..but....as soon as I load any tracks then the X pops up against audio out.
On the box it does say plug and play ..no drivers required.
When I remove the whole thing ...hard ware and software ...the reinstall I do get messages saying no drivers ...the device is not working properly...but even with the ASIO 4 all def in the system, I cannot force it to recognise the drivers.
I really don't understand the tech side ...but I'm getting the misery pretty good.

Sorry ..by " on the box" I do mean the packaging

Maybe a sample rate mismatch?
 

Hallelujah ! ! ! ! !

I did yet another removal and reinstall and set the drivers in Sonar to MME 32 bit......

This time ....audio out !! No Asio4all Audi box visible anywhere....but it seems Sonar is playing normally .
But it's 2.30 am here...I'll have to do a quality check tomorrow.

But a BIG thank you to all who helped and supported me in this trial....good on ya !

Latency with MME can be pretty significant, but at least it works. If you get weird distortion or ring modulation type sounds, you'll need to increase the amount of latency.
