  what():  Failed to open device: default. No such file or directory

The job audio/alsa-playback can be performed and I can hear the sound via headset plugged to the earphone 3.5mm Jack.

Submissions:

To Reproduce

  1. Plug the audio loopback cable to the earphone 3.5mm Jack port
  2. Install checkbox22 v2.9.0: sudo snap install checkbox22 --channel=latest/beta
  3. Install checkbox generic snap: sudo snap install checkbox --channel=22.04/beta --classic
  4. Launch checkbox: checkbox.checkbox-cli
  5. Select IoT Client Certification for 22.04 classic images (Automated Tests)
    • id: com.canonical.certification::client-cert-iot-server-22-04-automated
  6. Deselect all the jobs by pressing d, then select only Perform audio/alsa-loopback-automated from Audio tests category, and press t to start the session

pieqq commented 7 months ago

Similar to #273 there is probably at least some Alsa config to add in the snap, but I don't know if this will be enough.

hanhsuan commented 4 months ago

Simply test the binary inside debian and snap checkbox, it would only fail inside snap.
