Audio not detected on X1 Yoga 4th

[Jonas Gamao]

I'm testing out Kubuntu 20.04 on my 4th gen ThinkPad X1 Yoga, and Ubuntu's not detecting audio from it at all.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command only once, as it will automatically gather debugging information, in a terminal:

apport-collect 1861237

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

[Timo Aaltonen (tjaalton)]

probably needs 5.5 and newer sof firmware for it

[Daniel van Vugt (vanvugt)]

Yes, probably, but the bug needs to be assigned to pulseaudio to collect both Pulse and ALSA info when apport-collect gets run.

The reason why I didn't get to run ubuntu-bug or apport was because I was on my desktop when I made the report. Also, I just ran apport-collect 1861237. Where can I find the files and attach it here?

[Daniel van Vugt (vanvugt)]

I do the same with ubuntu-bug. You can ssh from your desktop into the affected machine, run 'ubuntu-bug' on the affected machine and then follow the link and complete bug creation on your desktop. FYI for in future.

[Daniel van Vugt (vanvugt)]

The 'apport-collect' command has attached the files automatically. It is showing the problem is that the kernel can't find a compatible driver so isn't offering any audio devices:

!!Soundcards recognised by ALSA
!!-----------------------------

--- no soundcards ---

[Daniel van Vugt (vanvugt)]

Interestingly bug 1847710 suggests that eoan (kernel 5.3) works, partially.

[Jonas Gamao (yamiyukisenpai)]

Yup. I can't control the volume at all, unless I use the audio plasmoid.

[Hui Wang (hui.wang)]

It is the problem of missing the firmware, the linux-firmware is going to include this firmware soon for 20.04.

[Paolo Pisati (p-pisati)]

Could you test if latest Focal kernel and firmware fix this issue?

linux-image-generic | 5.4.0.14.17

linux-firmware | 1.186

[Jonas Gamao (yamiyukisenpai)]

Just did the update today, and no changes.

[Hui Wang (hui.wang)]

Probably kernel-5.4.0.15 will have all needed patches for supporting sof driver. But the sof-firmware has not been integrated to linux-firmware. So when .15 kernel is ready, we could manually install the firmware and alsa-ucm-conf to test.

[Jonas Gamao (yamiyukisenpai)]

It's now fixed in Focal :-)

[Daniel van Vugt (vanvugt)]

Thanks. It's probably related to bug 1860697.
