I've been using Asio drivers in Producer 8.5, with my 2496 card. no problems except certain instruments (bass) cause sonar to crash. am wondering if using WDM driver might help?

Do you mean the Echo Layla 24/96? If so. http://echoaudio.com/pages/windows-drivers The driver has both ASIO and WDM in it (I think)

I'm assuming he means the M-AUDIO Audiophile 2496:

Sorry, I should have been more specific. I mean the M-Audio 2496.

ASIO works best with Sonar 7 if I recall. I presume same for 8.5 which I skipped and went to X1

Thanks, I think you're right.
