Sound quality

Hi from Italy,

I’m working on a 30-minute project (made of different mixed songs).
Every time I open the project and try to listen to it, the sound quality is very low.
It’s like the sound of a broken headphone wire, that’s why I initially thought that was the problem.
I need to wait nearly 20minutes to fix the problem. After that, it works.

Do you know why!?

Thanks
Fabrizio

Perhaps something is running in the background and interfering with the sound.
Try rebooting your computer before you start.

Ok, Thank you Steve.
