Some of the audio cases such as audio/alsa-playback, audio/alsa-loopback are broken on Jammy.

Impact image: Ubuntu Server 22.04 and Ubuntu Core22

Result

Ubuntu Server 22.04

The following result is from the output of audio/alsa-playback case

To Reproduce

Ubuntu Server 22.04

  1. Install OS
  2. Install snap checkbox, 
    sudo snap install checkbox22
sudo snap install checkbox --edge --classic
  3. Checkbox remote run the audio/alsa-playback in com.canonical.certification::client-cert-iot-server-22-04-manual test plan

Ubuntu Core22

  1. Install OS
  2. Install snap checkbox 
    sudo snap install checkbox22
sudo snap install checkbox --channel=uc22/edge --devmode
  3. Checkbox remote run the audio/alsa-playback in com.canonical.certification::client-cert-iot-ubuntucore-22-manual test plan

Environment

Relevant log output

- Checkbox session(s) (located in `/var/tmp/checkbox-ng/sessions/`, you usually want to select the most recent one)

- logs from the impacted components (e.g. `lsblk` if this is related to an issue when testing a disk...); a safe option is to install and run `sosreport` to gather as much log as possible.

One interesting thing is that if I install the alsa-utils or alsa-ucm-conf deb package on Ubuntu Server manually (not in checkbox shell), then the case can be executed and the I can hear the sound via headset without any problem. But I still got the output like below

Because I found the /usr/share/alsa path will appear after installing those alsa related deb package.

Another important thing is the path,/usr/share/alsa , exists in Ubuntu Server 20.04 and UC20 by default since the deb package alsa-ucm-conf is default package. So the case audio/alsa-playback can be executed on Server 20.04 and UC20 normally.

For Ubuntu Server 22.04

the alsa-playback and alsa-loopback tests passed when if we install alsa-utils debian package.

For Ubuntu Core 22

We have integrated the alsa-utils in checkbox-ce-oem snap and added a workaround to bind the alsa config in checkbox snap to system. And the both alsa-playback and alsa-loopback could passed. https://git.launchpad.net/~oem-qa/+git/checkbox-ce-oem/tree/snap/snapcraft.yaml#n130

@pieqq do you think the workaround is doable? Or we would like to have a better solution for this issue?
