Unfortunately, it was pre-installed in my laptop and now I have only the 33 one in the folder.

Okay, here it is: https://download.lenovo.com/consumer/mobiles/bhcn32ww.exe

I also attach 26WW version, which in my opinion works the best on this machine:

https://download.lenovo.com/consumer/mobiles/bhcn26ww.exe

Feel free to try both, which one works best for you. There is no risk in doing it.

So after trying all the possible solutions for the problem, the only one that worked was to change the drivers for the NVMe as shown on page 19.
I had this fix going for a while now and the issue is gone.
BUT I encountered a new one: Windows is now telling me to restart to complete the driver installation every time windows boots up.
That's not really a problem, but it's a little bit annoying.

 

Well it's way better than the crackling anyway.

 

Cheers

Exactly same problem here - cracking on the beggining and in the end of sound.

RST file and changing fast 8/16 option in BIOS didn't help.

Another vote about Lenovo and it's worst support I have ever met in my life - I will remember that for the future.

 

There is no problem in Win 10 safe mode.

Nothing changed after WiFi Transmit Power.

 

EDIT:

I only use BT headphones with my Y540.
Now I tested and no cracling sound is heard from the laptop speakers (Thank You!), but using Bluetooth the problem still occurs - but now I just noticed that it's the problem with headphones itself!

So thank You very much for Your help.

It seems that RST driver was solution for me too.

This worked for me. Thanks a lot.

I was worried so much because of this sound issue. It's shame how Lenovo can ship so many laptops with cleary faulty sound.

Finally happy that this BIOS update included an option to tweak whatever was causing the problem. But I can't help but wonder that we must be loosing something with 'fast/8' value. The earlier fast/16 seems more advanced.

If anyone can explain what does "Slow slew rate for a IA domain" mean, it would be great.

Anyways thanks Berni.

Hi to all. So i bought legion laptop about 3 months ago. After two weeks i noticed there is a crackling sound especially when it is charging. That is very sad. Then i bought BEATS STUDIO 3 headphones. Now it is working perfectly fine. No sound, No crackling problem with beats headphone. I am pretty sure it is because headphone has noise cancelling feature. So i highly recommend it to people if you have not find any solution and on budget.
