Yoga 9i no bottom speakers support in linux

2021-02-12, 21:09 PM

bottom speakers don't work, the c930 and 7i seem to have similar issues?

here are some logs and stuff of my machine

everything else pretty much works excpet gnome-settings won't detect the included pen in Wacom settings. Pen works in apps though with pressure sensitivity working as expected

from googling around apparently, this is also an issue on the c940, the audio needs to be initialized through the bios and so we need a bios update to fix this.


I opened an issue and the also GitHub issue tracker here alsa-project

Hi @zany130 

 

Thanks for the note and for sharing the details above.

 

The Yoga 9i isn't one of our Linux certified platforms so I have limited levers to pull on to get fixes done for Linux. Sometimes we get lucky and are able to get support from the firmware team; but realistically the chances of getting a BIOS update for this platform are quite small. The BIOS team are very cautious about anything that might impact Windows on these platforms.  I'll ask and see what I find. If there are details I can collect that might lead to a workaround/fix in the kernel that's much easier.

 

Mark

Is this a dead issue or do you think they might look into it?
