    Split front and rear audio jacks

    Hi!

    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?

    Thanks!
    Erik

    Not quite sure what you're trying to accomplish. I take it this is the behavior you desire?
    However, If I manually go into alsamixer and mute either "Front" (which is actually rear) or "Headphones", I only get sound from the other.
    If so, what is wrong then?

    "Front" (which is actually rear)
    Front = front speakers (not front jack)

    I would like to split the Headphones and Front channels into different Audio devices, in order to be able to use them simultaneously but in different applications. That's how I have it in Windows. I.e., Skype goes into Headphones, but VLC goes into Speakers. Also, I managed to get it working in Linux Mint a while back, but I don't think I used PulseAudio then.

    Perhaps there is a switch that you can use directly with the Realtek chip:

    !!HDA-Intel Codec information

    Codec: Realtek ALC892
