Hi there,

after my research I found out that Fedora is one of a few distributions that support 32-EFI systems. After the successful installation process I noticed that there's no speaker symbol in the tray bar.

My system is an Odys Prime Win 10 laptop with an Intel Atom x5-Z8350 processor.

Opening pavucontrol results in following message:

pavucontrol

I've tried to open Alsa-Mixer but with no success.

[dummy@localhost ~]$ alsamixer
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: connection refused

Fehler beim Öffen des Mixer-Gerätes: Connection refused

The command "aplay -l" outputs this:

[dummy@localhost ~]$ aplay -l

I actually got it to work. Well, kinda. I did the steps described in the PulseAudio section. Then I blacklisted the sndhdmilpe_audio driver as described here. The sound quality is pretty bad but it might be a matter of some tweaking.

Note: I don't use HDMI on this little machine so this solution works for me.
