[Bug 631808] [NEW] No sound on headphone jack

[Alexander Hunziker]

Public bug reported:

On a Thinkpad T400s, I have sound through the built-in speakers working
well, but as soon as I plug in an external speaker set into the
headphone jack plug, sound is muted. This does not happen under Lucid,
and does also not happen under Lucid with a 2.6.34 vanilla kernel.
