In a new install of Fedora-33 I have no audio. It appears that PA

For whatever reason the pa volume shows audio set for HDMI and my

is coming from the motherboard speaker j=output. The same connection
always worked with Fedora-32 and earlier ...

Am I the only one seeing this and what can I do to fix it?

I am experiencing similar issues in Fedora 33 (I performed a fresh install as well).

Occasionally, my system has no audio (with pulseaudio that is unable to connect), and to get it back I have to run these commands:   $ pulseaudio --kill   $ pulseaudio --start

I suspect that the problem could be ascribed to the desktop environment that I am using (i.e., Cinnamon), as every time I tried to use Gnome I didn't experience that problem. There were no such problems in Fedora 32. My audio interface is integrated in my laptop's motherboard.

Best regards, Marco

. That did not fix the sound problem in Fedora-33 However it did work on Fedora-32 which has had no sound for six months or so.

Thanks for the help ...     Bob

Did alsa recognize the sound devices? Check with aplay -l

I've had this problem with shifting sound devices because of the video (hdmi) device being recognized before the other audio devices. This makes sense, since the video has to be initialized early in the boot process. It is a race condition. Wolfgang's suggestion that you use pavucontrol to set the default sound device is a good one. That way, no matter the order that they are initialized in, pulse will always use the device you want as the default output device.

You can also change the alsa default device in /etc/alsa/alsactl.conf However, if the order of sound devices changes with every boot, that will be problematic.

You can put a file in /etc/modprobe.d to specify the order of devices explicitly, but that is more complex. Basically, put stanzas like the following for each device. alias snd-card-0 snd-hda-intel id="SB" options snd-hda-intel index=0 changing the card description to reflect the information from aplay -l and setting a different index number in the range 0-7 for each of them. The file name doesn't matter as long as it is unique for that directory, but choose something descriptive so you recognize it. ______

' Well now I am overwhelmed with more information than I can deal with.

I have been comparing the files mentioned for the Fedora-32 system that has a working sound system with the Fedora-33 which does not. Other than the xfce volume control Configuration that I mentioned earlier I see:

[bobg@Workstation-2 ~]$ pulseaudio --kill and then: [bobg@Workstation-2 ~]$ pulseaudio --start N: [pulseaudio] main.c: User-configured server at {fc279515ec6c4fa39007fba37b0f7d6b}unix:/run/user/1000/pulse/native, refusing to start/autospawn.

Nothing seems to work ... I will continue the effort, probably start fresh tomorrow morning.

Thanks,      Bob
