Sound Problem

Hi,

I've had my U-Mix Control Pro for about 10 months now and just recently the sound quality has been poor. I play music from iTunes on my speakers and it sounds fine. As soon as I go to mix the sound becomes very crackly especially with the bass. Through headphones plug into the controller it is even worse. I've tried different headphones as well would could it be?

Thanks.

Sure.

Windows 8
Running mix vibes 2.4.0
Updated to latest Firmware
Runs off my SSD 120 GB
I disconnect the internet when mixing so just a few programs like dropbox running.
Don't think I have a ram / cpu monitor

Let me know anything else you need to know.

Speakers work just fine without the controller whilst playing from Cross. I had a go again and this time it was even worse with the controller. It played for about 10 seconds and the sound just cut out. It does have the tendency when opening Cross to not recognize the controller. I normally close Cross turn off the controller and plug it into another usb port and then it works. Don't know if that makes a difference.

Your ASIO buffer is probably set to low IMO. What is it set at?

Not the most technical of people, is that the part in the preferences to do with the buffer size?

Don't know if I have found a way around it. I turned down the output slightly on the U-Mix Control volume panel and that seems to be okay now. It does however make a constant humming noise coming out of the speakers.

Yes - Preference > Audio > Buffer Size

Do you get it if you use the Laptop's battery, rather than running on mains?

If so, it's a Ground Loop problem most probably. Easily sorted. You just need to buy a Ground Loop Isolator.

Something like this
