[SOLVED] No sound on Lenovo Thinpad X1 gen 7

slackmund · 05-16-2022, 04:26 AM

Not sure is if this is suppose to go here, in Linux - Laptop & Notebooks or Linux - Slackware. Let me know if I'm posting to the wrong forum.

I'm having problem getting sound to work on this laptop. It's a fresh install of Slackware 15.0 and I'm booting the vmlinuz-huge-5.15.19 kernel.

I see this in dmesg... and think it is related to me not having sound. It directs me to a link for what I assume is drivers for my sound card ?? But that's where my knowledge stops. I have no clue if I'm suppose to install this, and from that URL I'm not understanding how to installed. Any help would be appreciated.

Hello slackmund & welcome to LQ.

I'd fix the firmware error(s). That's a show stopper.

Try to download them from Intel. The first one would go in /lib/firmware/intel/sof/sof-cnl.ri

Thank you so much for the warm welcome and for the great help. It took me a while to figure out how to do what you said. But it was the solution in the end.

For any newbie users like me that follow this post to solve same problem. This is what I had to do.

First I needed to clone the git repo that was linked in my dmesg (https://github.com/thesofproject/sof-bin/) I made a folder on my disk and did this command inside it

Code:

git clone https://github.com/thesofproject/sof-bin/

That gave me a folder named sof-bin

Then I did the safety measures (backing up files) mention inside the sof-bin/README.md

I then did the

Code:

sudo ./install.sh v2.1.x/v2.1.1

This gave me some new files inside /lib/firmware/intel/ I then rebooted. I'm not sure why but i got a kernel panic at first reboot. Was sure it all was foobar but did a hardboot and then it booted and I had sound. Amazing!

Thank again for the help and welcome. Happy first post here at LQ

Sorry - I'm clear as mud sometimes. Linux is a learning curve, steep at the outset.

Now mark this thread solved, so folks who search the threads can find your solution. It's on your screen near the top or under 'thread tools.'
