On the HP ZV5000 laptop the speakers do not mute when you insert a headphone plug. To work around this problem, you could use the cmix tool to reduce the Vol sound setting to 0. This did not affect the headphone volume. To affect headphone volume you would adjust the pcm parameter. When I emerged the latest version of nforce-audio (1.0.0292-r1), the pcm paramter is no longer available, and consequently there is no way to listen to music without it playing through the speakers, making it useless in a cubicle environment. I find myself unable to revert to version 1.0.0261 (which worked) because the ebuild has disappeared. Reproducible: Always Steps to Reproduce: 1. 2. 3.

To clarify: Under 0261 the vol parameter controlled ONLY the speakers and the pcm parameter controlled both speakers and headphones. Under 0292 and later, the vol parameter controls speaker and headphones. There is no pcm parameter available.
Is there any reason you're not using ALSA?
I'm not familiar with ALSA. To be fair, I'm also not familiar with whatever sound system I'm running now. It just happened to work until the latest nforce audio drivers were installed. I'll see if I can figure out what values to plug into the files documented at (google to the rescue: ) http://www.gentoo.org/doc/en/alsa-guide.xml However, if the vol parameter still controls both headphone jack and speakers, we'll be back at square one.
Ah, I just realized that I have -alsa in my USE flags and that is what puzzled you. Whenever an emerge -upvD --newuse shows a bunch of things that will be recompiled because of a new USE flag, and a number of new packages are going to be installed, I tend to disable that USE flag. I figure "I got along without it this long; why should I spend CPU cycles to fill my hard drive with applications and libraries I don't understand?"
Well, ALSA is the prefered audio system if you can use it, so I highly recommend making the switch
This should work with alsa's drivers, and I'm not interested in supporting other audio drivers unless alsa lacks support for a certain card.
I have things MOSTLY working under ALSA (occasionally mplayer comes up with no audio). ALSA even mutes the speakers when the headphones are plugged in (making it clearly smarter than the nforce-audio driver). Based on these experiences and your comments, I'm going to conclude that the nforce-audio package is deprecated and unsupported.
