No sound devices after Nov 02 2020 update for Ubuntu 20.04

Post by wallyz21 »

In my HK Ubuntu MATE 20.04 there is no hardware displayed at all in the hardware tab of the Sound settings after updating to kernel:

Linux odroid 4.9.236-98 #1 SMP PREEMPT Fri Oct 30 14:43:59 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux

Code: Select all

$ aplay -l
aplay: device_list:274: no soundcards found...
$ 
I haven't tried my 18.04 system yet and I think I will hold off!

There were other problems with sound on 20.04 related to alsa, going to pulseaudio fixed it for me.

We could reproduce the issue with the new kernel update package. :(
We will try to find a root cause soon.

I noticed another kernel .100 has been pushed out. Doesn't seem to have addressed the sound issue! Still no sound devices.

Sorry for the inconvenience caused and glad to hear the new kernel update fixed the HDMI sound problem.
There was an error in a SPDIF related device-tree change. We've rolled back the wrong patch.
