DJM450 - Bad audio recording through Rekordbox

Hi guys,

I'm getting a consistent crackling sound on all of my recorded mixes through Rekordbox.

Using an XDJ700 and DJM 450 set up, with the 450 plugged into my laptop via USB. After googling, the general consensus appears to be that if you increase the buffer size on the 450's input settings (within Rekordbox), this noise should disappear. Unfortunately, this has not been the case for me, and even on maximum buffer size I am still getting the crackling noise.

I have also tried adjusting the registry as per this article - https://windowsreport.com/windows-10-april-update-audio-issues/

Specs:

• Lenovo T495
• Ryzen 5 PRO 3500U 2.10GHz
• 8gb RAM
• 256GB SSD

Any advice would be really appreciated.

Thanks
