I installed Lubuntu 13.10 (64-bit for Mac) on a MacBook today, and it
seems to be working well except for one problem with the audio.
If I use the laptop speakers, all is well. The volume controls are as I
would expect, and the volume level is good.
But when I plug in the audio cable plug (that connects to my stereo
amplifier) into the headphone plug on the Mac, I get no sound.
On investigating it more, I discovered that if I (in pavucontrol) slide
the volume slider all the way to the right, I can hear a faint sound
through the amplifier.
I also noticed in pavucontrol, that when I plug in the plug to the
amplifier into the headphone plug, the device switches from "speakers"
to "headphones", and the speaker output is muted. I think this is
I tried looking at the audio controls in more detail in QasMixer, but
didn't find anything that would fix the problem. If I set it to "Line"
output, and use the "Line Boost", I get no output. It seems I must use
the "headphones" device.
Does anyone have any idea why the headphone output is so terribly faint?
