[Solved] Case headphone jack not working
Hello!
The 14th of November I built my first PC, and as expected, I'm running into some issues.
I managed to solve some of them but there is one issue that is heavily inconvenient and I didn't manage to solve: the case's headphone jack is not working. Since I often have to switch from speakers to headphones it's pretty annoying to unplug the speakers from the back of the motherboard to plug my headphones in.
I have an ASRock B450M Pro4 mobo and the case is a CoolerMaster Masterbox Q300L, running on Kubuntu 19.10.

Any help is appreciated.
Thanks in advance!

I assume the internal case-to-motherboard wire is connected. What audio frontend are you using? Pavucontrol?

The cable is indeed connected and I'm using pulseaudio.

Do you have log-level=debug enabled in /etc/pulse/daemon.conf?
Does the output jack show up if you open alsamixergui?

log-level=debug is disabled.
alsamixergui shows "Master" and "Capture".
(P.s. Never used alsamixergui before)

And master doesn't give front output?

I'm not really an expert in manual configuration, but aplay /f and /F and alsa-tools-gui should list all your devices and jacks and you should be able to retask jacks with hdajackretask if Front is detected.

The thing is that even if I plug the headphones in the case the Master output still plays on the speakers (mobo jack). Also, both aplay /f and aplay /F doesn't work.

Just change the default device.

Was the first thing I tried, didn't work.

Looks like the case-to-mobo cable wasn't all the way in, now everything works as expected.
