Audio fault on Lenovo 100E Gen 2 Intel Celelron N4020 #305

Audio fault

Lenovo 100E Gen 2 Intel Celelron N4020 4GB 32GB eMMC 11.6 Inch Chrome OS Chromebook

Running Ubuntu with the Mate desktop, using the sof-setup-audio and SOUNDCARD=rtk sof-setup-audio scripts. It does give a sound when the login screen asks for a password, but in the desktop there is no sound when playing youtube videos and the sound icon in the panel is permanently muted and can't be changed.

Otherwise this is a fantastic and very useable implementation of Ubuntu. Wel done and many thanks.

Run:

systemctl --user mask pipewire.socket
systemctl --user mask pipewire.service

and reboot. Thanks for the praise :D. Feel free to donate to Breath.

Thanks for the quick reply. Unfortunately this doesn't seem to have fixed things, unless I'm doing something wrong.

Aha! Some progress. I have found that, after booting, if I run:

pulseaudio --kill pulseaudio --start

I now get working sound.

So all I now need to know is how to make it work straight from booting.

Would you mind joining the Discord? We could debug this issue faster there.

BonzoFerret commented 2 years ago

I'd love to, but it seems Discord thinks I've breached its terms of service before I even managed to get the account set up.

OK some feedback. I rebuilt breath from scratch and re-burned my SD card using ubuntu and the mate desktop.
Audio still did not work after running sof-setup-audio but running this extended the boot time considerably I then realised that I hadn't run

systemctl --user mask pipewire.socket systemctl --user mask pipewire.service

I did that, and rebooted. Still no audio. I then ran sof-setup-audio again and rebooted - still the longer reboot time, but this time hurrah! I have audio. Audio is at maximum volume after reboot. I also note that, even though I turn it down, it's still at maximum volume after a subsequent reboot.

Further update:

I tried again just to check. Again I rewrote the SD card, using Ubuntu and the mate desktop. Again I had no audio after running sof-setup-audio but I decided to investigate further. The sound icon on the panel was showing muted and there was no sound from a youtube video, and when I clicked on the sound icon it wouldn't unmute. However, when I went into sound settings I noticed three things.

  1. There was no device listed in the hardware tab.
  2. There were four options in the input tab which read:

Celeron/Pentium Silver Processor High Definition Audio Celeron/Pentium Silver Processor High Definition Audio <- this one was selected by default and working Monitor of Celeron/Pentium Silver Processor High Definition Audio Monitor of Celeron/Pentium Silver Processor High Definition Audio

  1. There were two options in the output tab which read:

Celeron/Pentium Silver Processor High Definition Audio Celeron/Pentium Silver Processor High Definition Audio <- this one was selected by default but not working

When I chose the first option in the output tab the audio on the youtube video came on. But the panel icon remained marked as muted.
