Speakers not working on C930 / C940. Please help!

2020-02-26, 16:39 PM

One of the major selling points of the C930 / C940 is the audio quality and the sound bar. But only the front speakers actually work. The back speakers and the bass speakers don't, which makes the sound on this laptop really tinny, and some of the worst audio I've experienced on a laptop.

 

There's a lot written about this already. See

 

 

They say that the problem is that the amplifiers connected to the bass speakers aren't being initialized in the BIOS. 

 

Lenovo: can we get a fix for the BIOS, please, so that the speakers will work?

It might be worth mentioning that this case does not apply to Windows installations.

The speakers function as intended on Windows 10.

The reports mentioned refer to Linux installations - still a small minority.

 

So all you Windows users - keep calm and carry on ...

 

I am not sure, whether  this justifies a new BIO or not but I suppose you can always tryS

I looks like those other bug reports go back several months. How can we get more attention for this problem? And I assume it might be connected to the crackling audio issue that I'm experiencing as well, for which I haven't found a solution either.

Does anyone from Lenovo monitor these forums? My Yoga C940 speakers are still crackling, static, hissing, whatever you want to call it. It goes away where there is nothing playing on the media player and no system sounds, but the loud static or hiss pops on everytime a sound occurs. Can someone please help resolve this?

 

Thanks!

Matthew
