Other Linux desktop environments have moved to Wayland, but that's not
an option for Sugar yet, needs development.

That's probably how ALSA works on your laptop.  It is fixed on OLPC OS
by adding alsactl and amixer commands to startup scripts.  It can be
fixed longterm on your laptop by changing ALSA defaults upstream.

Other Linux desktop environments have moved to PulseAudio, but that's
not an option for Sugar yet, needs development.


PulseAudio handles initial levels more gracefully than does ALSA.

Thanks for your work.

It's a Wiki, and you can edit it.  I see you have an account.  I would
like to see this TOAST offered, as the process that led to it (thanks
Ruben!) includes testing that gates release, which is something that
Fedora SOAS does not do, as shown by the most recent release which
doesn't start Sugar.  And it's not the first time that has happened.
