General sound issues on Hp Dv6 pavillion 2155eo

I've been researching this problem for months and there seem to be general sound issues with the HP-pavillion laptops and sound. I'm using arch with both the pulse-audio and alsamixer frameworks up and running, but alsa and the hardware are disagreeing on several points. The laptop has both a regular sound interface and hdmi and therefore the video-card from nvidia has some sort of soundcard attached to it aswell.

The issues I'm having are:
The alsa-mixer levels are not acting coherently, I think pulseaudio might reset them, but this happens when certain applications start as well, for example when adjusting sound levels within VLC and sometimes when using flash. They are also not responding very well to storing and restoring the alsa levels.

When I plug in something in the headphone outlet the laptop speakers are not muted

The laptop sound controllers are not working, and are not responding to xev very well, so I can't really find out the keycodes

I wonder if the issue could be that there is a conflict between the sound drivers and hdmi drivers. In this case I would like to drop hdmi, blacklist it or whatever, I don't use it anyway.

I also ask myself if it could be a problem with the snd_hda_intel module not knowing what model the laptop is, but I do not know how to tell it what model I'm using. I found no instructions for arch, just other distros, telling me to add a line in some different alsa-config file.

I'd be thankful for any help,
