Re: T480: Cracking disturbing noise when playing sound

I agree that it's not good to have the laptop run on full native frequency (for my CPU it's 2 GHz) all the time, but I see more the problem that the CPU only runs with half the speed it is capable of with my 99% CPU hack. Anyway, Lenovo should fix this. The T480 is a laptop for professionals. It should not have issues like this.

Definitely agree there. This type of issue's unfortunately been common with the 8th Gen Intel CPUs across many brands. Hopefully they can release a BIOS update to deal with this.

I will say that I noticed an improvement if I go to the "Dolby Audio" program and turn off the "Surround Virtualizer", so if you haven't tried that, maybe it will help you as well?
I came looking for if there's an Equalizer scheme that might fix it.

A good suggestion but sadly, it doesn't seem to have helped. :(

 

I've submitted a formal support request to Lenovo. It's ridiculous this issue still persists for so many.

I have just received a new T480 and I have the same problem.

Super bad audio quality with internal speakers, headphones, external speakers....

Cracking sound and noises!

 

How did you fix this?! I can't disable speedstep, that is not acceptable!
