Comment 3 for bug 587356

Ok, just for future reference, what is the proper way to reload new alsa option(s) that are changed/edited in alsa-base.conf? Besides restarting the machine? I used to know that in Ubuntu 9.04, but that way is obsolete now.

I just installed new alsa-drivers from ppa, removed model quirks and restarted. Currently, without position_fix=1, my sound now sounds like tweeters are playing it.

I just realized that I have to choose the "Analog Stereo Duplex" profile to see input hardware on the input tab. Those profiles are confusing, or at least unintuitively named.

If I choose my Microphone 2 from the dropdown on the Input hardware tab, I can see Input level rising when I tap the internal microphone, but no sound that microphone "hears" is coming out of the speakers.

I'm gonna add position_fix=1 and restart (which I'm sure is not the optimal way to reload stuff, please educate me), just to be sure everything gets reloaded. I'll report my findings.
