I Need io4 Alesis driver

My io4 Alesis previously used 4 24 bit audio input ports. Suddenly this is no longer available, it only allows 2 inputs. I find everything but helpless. I think the faulty driver should remove and reinstall it, the system will not allow it. So I have no way to use Alesis io4 anymore. Please give me help. Thank you!
I use CeakWalk Sonar x2

  • Hello,

    Thanks for posting. 

    What driver are you using that you're receiving this error message? The IO4 is class-compliant, so it won't require any drivers to communicate with your computer. Refer to this helpful article here that will guide you through how to troubleshoot your class-compliant connection. 

    I hope this helps!
