I'm new to Ubuntu.
In my old Windows installation I could easily separate the front and rear audio jacks on my computer in the Realtek HD Audio app. Thus, I know that my soundcard is capable of separating outputs.
However, I've not been able to do so in Ubuntu. If I turn automute off in alsamixer, I always get sound from both rear and front. If I turn it on, I'll always get sound from headphones only, if they are plugged in, and speakers only if headphones are unplugged.
However, If I manually go into alsamixer and mute either "Front" (which is actually rear) or "Headphones", I only get sound from the other.
Does anyone have any idea on how to solve this?
