Subject: Kernel 3.2, and "speaker" controlling headphone path
Date: Wed, 11 Jul 2012 12:50:20 +0200 [thread overview]
Message-ID: <4FFD5A6C.1060401@canonical.com> (raw)
It seems like on one machine the "Speaker Playback Volume" was part of
the headphone path, in combination with PulseAudio this is leading to
muted headphones.
One of my colleagues wrote a workaround for that specific machine - I'm
providing links in case you're interested:
