[alsa-devel] Laptop (Samsung Q45) speakers unmute when master channel is unmuted even with headphones connected
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@bugs.debian.org CC'd in follow-ups.

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

Thanks.
What if you use model=auto option?
Also it may be better to try the latest sound git tree: git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git
