Sound stopped working soon after install on Dell XPS 17 (9720)

Hi there, after trying a couple of linux versions I’m really excited to be using Fedora, I’m impressed with how well it works with i3 Desktop.

However, I installed Fedora a few days ago and sound was all working fine on the day that I installed, even after rebooting a couple of times. Since then I’ve not used the laptop for a couple of days. Today though, I booted it up and now I don’t have sound anymore.

I’ve had the same issue before installing Manjaro on this computer the sound would work immediately after install and then a day later it would stop working. I’ve tried upgrading alsa-sof-firmware and rebooting but that has not fixed it.

Not sure what to do from here, can anyone help?
