No sound after 'sudo dnf update' today

Hello all.

I’m on a fresh install of F30 (my first time using Fedora) and after running ‘sudo dnf update’ this afternoon I don’t have any sound.

My motherboard has a Soundblaster Recon3di onboard. Checking dmesg originally showed that there was no (longer?) any firmware for this device in /lib/firmware which I have rectified and now dmesg shows the device correctly.

I’m pretty sure I’m using PulseAudio (ps aux | grep pulseaudio) but I can also grep for alsa and get a result so I’m not 100% sure. I can and have run alsamixer and fiddled around a bit with no success.

I’ve done a few random things from here: and here: F29: Sound turning on "magically"

While I’m not completely new to Linux in general, I’m new to Linux as a desktop OS. I’m trying to make this post as helpful and informative as possible but I’ll probably miss something. I’ll do my best to follow steps and advice :slight_smile:

Was sound working before the update?

Hello. Yeah, It was.

Assuming that was your most recent upgrade, can you run sudo dnf history info and post the results here, please? If it wasn’t your most recent upgrade, you can run sudo dnf history which will show you the history of all dnf transactions, identify the one that affected you and then do a sudo dnf history info <transaction_id>

I’m going to chalk this one up to user issue. Things on Fedora work slightly differently to what I’ve been used to (Ubuntu) and I think I messed up the update which broke sound plus a few other bits of software.

I came to this conclusion by getting frustrated, reinstalling Ubuntu, remembering why I didn’t want to use Ubuntu anymore, reinstalling Fedora and paying attention to the update which I allowed to work properly.

Basically, PEBKAC :slight_smile:
