Issues running FLX-10 with Rekordbox in Windows 11

I am experiencing quality sound issues 10-15mins after starting a DJ set. Sometimes there are noises (cracking sounds) or the sound quality start to sound like it was clipping. I am sure there are no issues with the wires nor the sound system nor the level (I am always below the yellow leds)...Indeed the sound starts working well at the beginning. I am using an Intel Core Ultra 7 155U 2.10GHz with 32Gb RAM that I bought 6 months ago.

I have downloaded all latest firmwares and drivers, I have unistall and re-install Rekordbox (latest verion). 

I am always re-starting the computer before I use Rekordbox and it is the only program I run while I am DJing. 

I will appreciate any help.

Regards,

Patricio
