> > Hi everybody, > > I'm totally stuck with a sound problem I fail to debug on my own. > Please tell me if my question should be directed to ubuntu or to this list. > > My setup: > Asus P5Q Motherboard with Realtec ALC1200 soundchip. Stereo speakers plugged in to the rear output and headphone speaker/mic combo plugged in to the front jacks. System: Ubuntu 12.10 > Desired behaviour: Sound is played back on headphones AND rear speaker. Front mic should "just-work" > > Problem 2: > This is the biggest problem. > As soon as I plug in the front mic, Inside gnome-alsamixer the volume for master, surround,center,lfe start to jump between on and off. Why is the Front mic jack controlling these values? How can I debug this behaviour? I just want them to stay the same, if the mic is plugged in or not. > Inside the gnome volume settings, the output port starts to jump between "Analog Output" and "Analog Headphones" > This look like problem in Jack detection of the headphone and Mic Jack of front audio panel alsamixer -c0 Does the playback switch change rapidly on and off in alsamixer ? Do your computer chassis have a hda front audio panel and you connect them to the front audio connector of the motherboard according to the user manual ? Does it help if you disabled the automute switch ?
