Since installing the Akai EIE my Sonar 7 will not output any audio.

Yes..all drivers thoroughly checked...everything set perfectly correct...I've spent three solid days installing every which way.
I get audio out thru Windows Media Player and Soft Synths ....but Sonar has the now infuriating X against WDM USB audio out ...
This is THE WORST software malfunction I have ever experienced . Asio 4 all has a feedback address but no reply to my query although they hint that this is an inherent fault.

Apart from Control Panel/ Sound and the preferences in Sonar I've nothing left to try to rectify the problem.

Totally dejected now !

Try a different driver.  ASIO4all screwed up my system too.  ASIO4all attempts to use WDM as ASIO.  It works for some, sometimes.

Doesn't the EIE have dedicated ASIO drivers? ASIO4ALL is not recommended except as a last resort solution for people who are forced to use the dedicated sound chip on a laptop.

Thanks...I've tried every available ASIO 4.all driver.....still the X

Thanks...I simply don't know..I'm using full PC.

As AT notes ASIO4all is just a wrapper that in effect disguises WDM drive as an ASIO driver.  I would uninstall the ASIO4all driver and see how it works with just the WDM driver. 
 
I can see from the AKAI web site they do not do an ASIO driver and actually recommend ASIO4all.

hm, the akai site actually recommends using the asio4all driver http://www.akaipro.com/kb/article/1452

jinx
 

Ok thanks..I will certainly try it !

Thanks...oh yes..I know that page by heart now....

Maybe. I should uninstall Sonar ..upgrade or something....what a total mess.
