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.

Could you run alsa-info.sh with --no-upload option, and attach the generated file?

Here you go!

Thanks.

What if you use model=auto option?

This is fixed in 2.6.30, but only if I use the model=auto option. :)

What about with the later version, e.g. Linus git tree? Or you can use sound git tree git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git

I think this was already fixed there.
