No sound out of a fresh install of Fedora 32 on a new motherboard

Hi folks,

For various reasons I decided I needed to update my mobo. I went for an MSI B450 Tomahawk Max with a Ryzen 5 processor, 2x 16gb DIMMs. I also added an SSD for my boot drive. I moved the XFX Radeon RX 580 GTS XXX from the old machine to the new, as well as a couple of older SATA drives that have my /home directory on.

On the previous motherboard, the sound just worked. I single cable plugged into the mobo going to woofer with separate left and right speakers attached to that.

On the new motherboard, there are 4 possible sockets, and none work. When I checked the sound preferences, it was showing 2:
1) Ellesmere HDMI Audio [Radeon RX 470/480 /57/580/590] - Disabled - Digital Stereo (HDMI 4) output
2) Starship/Matisse HD Audio Controller - Disabled - Off

If I select the first, I can configure it off, but if I select the second, I get no option to configure it on.

I'm guessing that the first is trying to send the output to the monitor (the graphics card has no jack sockets!) but my monitor has no speakers.

I've tried googling but with no success and most places just suggest loading various pulse-audio packages, which I already have.

Can anyone advise please?

Many thanks,

Dave

starfiend,

The sound on my B450 Tomahawk Max on EndeavourOS is working fine.

Go to Sound Preferences.

I connect to the central (top) RED audio port of the 6 available and to a USB 3.0 port with my cheapo Logitech Z120 laptop speakers:

I am using HD audio which is enabled in the UEFI/BIOS.

Attached are 3 screenshots.

Make sure the Output volume slider is moved to the right on #3.

I definitely tried that one, the manual sort of implied, without being very clear, that that was the correct one.
Unfortunately I don't have any USB speakers ATM.

Thanks, I didn't know that was there, so I've just gone in and checked it. It looks to have been enabled by default, but thanks anyway.

Although my monitor (an AOC) does not have built in speakers, I have discovered that it has an audio output jack socket. I've plugged my speakers into there for the time being, but the sound is very poor quality to that that came off the old motherboard. I'm guessing there's some sort of driver I've not installed, but I just can't identify it.

Thanks,

Dave
