Try downloading alsa-driver-1.0.16rc2. It has some new patches in it.

If that doesn't work, please report back with the link generated from running http://bulletproof.servebeer.com/alsa/scripts/alsa-info.sh

I tried googling around but no helpful content so far. I have a laptop with built-in sound. It uses the HDA_intel kernel module. My problem is that I can't silence the onboard/built-in speakers when I plug in the headphones to the machine. Muting sound would lead to all jacks and audio ports to be silenced -- not just the built-in speakers, which I intend to mute solely leaving sound alive on the headphone jacks. There are no channels readily observable to differentiate where sound goes and to which port with alsa-mixer. The behavior I would like to achieve is one that will allow me to mute onboard speakers while continuing to have the headphones receive audio signals. Has anyone ever done this? Any pointers to documentation will be appreciated.

My board has the Conexant CX20549 Codec. I think is uses the ALC268 module. I checked gmane and saw that a fellow user got snd-hda-intel working with the NVidia MCP67 chipset with a patch received from linuxant.com. I tried the method and when patching i had encountered errors.

Thanks for the reply. Here is the link http://pastebin.ca/886945
