Since Linux 2.6.28 and through to 2.6.30-rc4, the hda-intel driver has had a
bug on my laptop (a Samsung Q45).

If I connect my headphones, the laptop's internal speakers are muted--fine. But 
if I then mute and unmute the master mixer channel, the speakers come back to
life, even though the headphones are still connected.

Please keep 517241-forwarded at bugs.debian.org CC'd in follow-ups.
