Description: Ubuntu 20.04.2 LTS
Release: 20.04

Problem:
Cannot get both wifi and sound working on a Dell XPS 17 9700 (i9 processor) at the same time.

With the 5.10.0-1029-oem kernel wifi works, but sound (microphone) does not.

With the 5.11.0-20-generic kernel, the microphone and sound works (thank you for fix: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1921632) but the wifi does not.

With the 5.11.0-20-generic kernel and the linux-firmware (1.187.14) pkg installed (sound works but no wifi):

Information with 5.11.0-20-generic kernel:

What I'd like to see is the sound fixes from 5.11.0-20-generic kernel make it into the OEM kernel so that both wifi and sound work on the Dell XPS 17 9700.

[You-Sheng Yang (vicamo)]

ath11k issue, bug 1930637, should have been and only have to be fixed in 5.11.0-20-generic. 5.10-oem is not affected by that issue as you also mentioned that in the bug description. I'm not sure if I fully understand what you mean. Please attach your dmesg log.

[Jeremy Miller (jmillerv2)]

Although I can get sound working, I cannot get wifi ath11k to work at all on the Dell XPS 17 9700 with 5.11.0-20-generic. Please see the attached dmesg.

[Jeremy Miller (jmillerv2)]

Unfortunately 5.11.0-20-generic does NOT fix the wifi. As you can see in the dmesg output above, the ath11k driver is present but doesn't seem to enable any interfaces.

Status changed to 'Confirmed' because the bug affects multiple users.
