Speakers not working on Ubuntu 20.10 - Thinkpad E14 Gen2 Intel

Hi @rodmaureirac.
My speakers do not work with a default install of Ubuntu 20.10 on my Thinkpad E14 Gen2 Intel.
I had to modify grub parameters as described in this post:

Please note that this fix disables the internal mic...

Hi, your problem is quite similar on what happened with X1 Series. Maybe it's the same issue. Can you try this?:

• Reset grub settings
• Remove pulseaudio with sudo apt purge pulseaudio pavucontrol && rm -rf ~/.pulse/
• Reboot your system
• Append blacklist snd_hda_intel and blacklist snd_soc_skl inside /etc/modprobe.d/blacklist.conf
• Append load-module module-alsa-source device=hw:0,7 inside /etc/pulse/default.pa. (Note that hw address may change. you can use arecord -l in order to find yours).
• Reinstall pulseaudio sudo apt install pulseaudio pavucontrol

Hope this helps you. It's all i know about audio on ThinkPads

Thank you for the feedback.

Unfortunately removing pulseaudio would also remove ubuntu-desktop. I followed the rest of your steps, but it didn't work for me.

I'll just stick to the first workaround and only have a working speaker and no microphone. (Totally fine with that. )

Hi, I hope I'm not too late to the game, but I had exactly the same issue with the same notebook.

I solved it by installing the firmware-sof-signed package like mentioned in the audio section here.

Afterwards, I also removed the kernel parameter snd_hda_intel.dmic_detect=0 in /etc/default/grub and rebooted my system.

Now audio and also the microphone work perfectly.

On Ubuntu 20.10? What's the version number of sof?

[PaddyKe]

I'm using Debian testing (bullseye). The version of sof is 1.6.1-2.

Unfortunately this did not resolve my audio problems. I'm now back to the workaround as mentioned in post 1.
