KMix seems to default to that, but seems to have no control over audio when it does. If I select "HDA Intel", all is well.
What is PulseAudio and if I don't need it can I get rid of it?

Pulse audio is a current generation sound server for linux. It sits on top of ALSA and has certain features one might like. Do you need it? No, you don't NEED it. it is quite nice when it works though.

I'm not sure that it does, though. In KMix, with Pulse Audio selected, I see exactly one slider ("Master") on the Output tab and one slider ("Capture") on the Input tab.
When I select "HDA Intel", I get 12 slieders on Output, 5 under Input and a tab called Switches that has a bunch of stuff.
What constitutes "when it works" with Pulse Audio? I'm thinking that this isn't it. :-)

Pulseaudio has had some very rough edges but it is maturing nicely. It offers very powerful features such as dynamically selecting sound devices per application, setting volume per application, and even creative fancy things like automatically muting all other applications when your soft phone rings and is active.
To get the most out of it, you may want to use pulseaudio's native tools. I do not recall the packages or even the correct names (names such as paman, padevchooser come to mind). I suppose one could do an apt-cache search pulseaudio - John

Peter, you should Google about what is Pulse Audio, who is Lennart Poettering and why a lot of linux users all over the world don't like PA and are a bit skeptical about switch from the Upstart to the systemd if you're really want to get familiar with PulseAudio sound server.
As for PA, it is really pretty nice daemon to use in case you'd be exceptionally lucky not to hit any of the bugs in it and related environment. To correctly control sound volumes on PA-enabled system one would need to use PA-enabled mixer (KMix is not - yet?). I've seen pretty nice implementations of PA mixers with decent GUI but they all were using Gtk2. Don't know if there's something of such kind available based on Qt (especially if we limit ourselves with Qt3).

Yep. With PulseAudio, capture and output volume levels are controlled on a per-application basis, and globally (which is the single volume control you're looking at there). So you can say "I want my phone application to be three times as loud as Amarok" *and* "I want all volumes to be increased because I've switched from headphones to weedy speakers". (As far as I know Trinity has no mechanism to control per-application volumes, unlike KDE4, but the Gtk pavucontrol program works fine.)
What you don't get are the dozens of confusing volume controls with confusing names that modern sound cards provide, half of which typically aren't hooked up to anything at all and 90% of the rest of which are hooked up to inputs or outputs that you don't have anything plugged into.
I don't really see this as a downside.

Working as designed. :)
