Hi,
I had a problem with muting speakers when headphones are plugged-in on my Benq S32B. So I added proper board configuration to sound/pci/hda/patch_realtek.c and now it works.
I wonder if anyone has similar hardware (S-series Benq laptop) to test the patch (attached) if you find it useful.
Thanks for the patch. The lack of headphone mute is likely because of codec SSID value. The realtek codec is supposed to have some special SSID indicating the assembly information, but many vendors don't follow it.
Could you try the patch below and try model=auto? It's found in sound-unstable tree, too...
Downloaded and installed http://ftp.kernel.org/pub/linux/kernel/people/tiwai/alsa/alsa-driver/alsa-dr... in accordance with those instructions: http://alsa-project.org/main/index.php/Matrix:Module-hda-intel
loaded it with option 'model=auto' as you suggested, launched mplayer and plugged/unplugged headphones several times. Unfortunately, those actions weren't recognized and laudspeakers continued playing without any interruption.
Please see alsa-info.sh output in attachment.
