I just started running Ubuntu 20.04, MATE 1.24.0 on my desktop. my case has a front i/o with audio out and microphone in, and I typically use these for my razer headset with a headset/microphone splitter.

On the rear i/o panel audio out I have a set of (stereo) speakers plugged in. Now, on Windows I haven't had any issues switching these outputs, but in Ubuntu it seems like the headphone out is taking over any time it's plugged in, regardless of what output I have selected from the drop down in sound settings.

Now I don't really mind unplugging the headphones to get the speakers to work, but it would be nice if there were a solution that could resolve the issue.

So to clarify and simplify: speakers in the rear i/o work fine when the headphones in the front panel i/o are unplugged, but the output defaults to headphones when they're plugged in, regardless of settings.

Anybody out there know where I'm going wrong here? Thanks in advance!

SOLVED (mostly)

Turning off automute in alsamixer sends the audio signal to both ports simultaneously and you can then use the mixer to mute one or the other.
