Re:Lenovo Y540 crackling sound

I installed IntelOptaneMemoryAndStorageManagement, launched the program, and disabled "link power management", restarted my computer. And the audio problem was not fixed for me.

Stumbled upon this post "Set wifi transmit power to 4 in change adapter settings"

 

Instantly solved it for me. 

 

 

 

 

Quick guide how to do it.

 

Step 1 Click the Windows button and search for "View network connections"

Step 2 Right click the "Wi-Fi" and select Properties

Step 3 Then click the button "Configure"

Step 4 Click on the tab "advanced"

Step 5 Scroll down and click on "Transmit power" 

Step 6 select value "4.Medium-High"

 

 

If it still doesn't work. You can try selecting one of the other values. 

 

 

 

 

For me it has been clear from the start that the audio problem i experienced was very much related to the 2.4ghz wifi transmition.

And im guessing for most people this solution wont work.

This worked for me: 

 

  1. Right click on wifi icon (right bottom of task bar) and choose Open Network & Internet Settings.
  2. Now you are at Network Connections window, Status tab (win10), click on Change Adapter Options
  3. Right click on your enabled network adapter (Wi-Fi) and click on Properties
  4. Now you are at Wi-Fi Properties window, click on Configure button.
  5. Click on Advanced tab,
  6. You will see properties in a multilist window, choose Transmit Power.
  7. There will be a setting of selected property in the right side, choose the 4- Mid-High or 3- Mid option (I use 4, and default was 5-Highest)

Hi, I just updated to the new bios BHCN39WW and I haven't heard the crackling sound anymore. Did this fix the problem or is just me?

 

Previously I had to use the solution by berniwa in page 20.

I couldn't help notice that in trying to fix the crackling sound, people were able to swap in and out Realtek Sound drivers in their Y545s. I'm interested because every since my first sound driver update, I've had to deal with the loss of the graphic equalizer, loudness equalization and soundzreal EXP (meh enhancement tbh). Dolby Atmos didn't survive either, but "premium" sound took the back burner to plain old normal sound. And at first it was a chore, to find not only the right drivers to restore my sound enhancements (6.0.1.8501), but if I made the mistake of updating with windows update or lenovo without close supervision, an incompatible sound driver would sneak in and I'd have to spend the next hour erasing every trace of the new drivers from the registry, device manager and program directories. Not to mention Realtek audio console, loves to have a problem, just when everything else sound wise is coming together. I can throw pic related together in 10-15 mins now, if my drivers get jacked.

 

That's the blog behind my extemely fun little sound problem and jerry rigged solution, Just wondering since you guys were swapping out drivers like crazy, was this ever a problem for you and if you can point me to a more recent and decent sound driver. 

 

 

 

 

 

 

 

Thanks and I almost forgot my two cents on the subject of these crackhead sounds. In the attached pic (the blue link right below this post), is something I have never heard of before purchasing a Legion Y545 and to be honest I have been leery of it eventually becoming a problem in the future. "Tie up the the same type?" in one jack? No thanks, next time, just charge me $20 for an extra headphone port, because that's just what I need is a crackling voodoo, microheadphoneinput port from hell in the future. Anyway have you looked into that as the possible culprit?
