Change volume in KMix not change system volume. Disable volume in KMix not disable sound in system.
I can change system volume only when I use PulseAudio volume control (pavucontrol).

Reproducible: Always

Which version of kmix is used in this distro?

Does it present four fixed tabs as per the screenshots here:
http://pulseaudio.org/wiki/KDE#KMix

If it does look like this, can you be more specific on the problem as
kmix in PA mode should behave pretty much identically to pavucontrol.

If it doesn't look like this, please contact your distro to ensure it is
compiled/included. I have made available patches to ensure that this
mode is enabled for older versions of kmix too.

Yes, it's have fixed tabs.

Sorry, look like I report this bug by mistake. I try to change volume
using volume buttons on laptop - in KDE environment this buttons change
volume of main channel, what selected in KMix. But there is another bug
- I have HDMI and analog output. KMix selected HDMI by default. I try to
select main channel by hands, but after reboot KMix again select HDMI by
default. When I try to use volume buttons - KMix change volume of HDMI,
but not of Analog. Here I think there is a problem PulseAudio and KMix
communication.

Okay, there is a no problems with PulseAudio back-end, but for some
reasons KMix selected HDMI as main channel after reboot. It's KMix,
PulseAudio or Phonon bug?

I'll have to look at the code, but I thought I'd made kmix behave
correctly with regards to setting it's "Master" channel according to the
"Default/Fallback" device in PA, but there were a few tricky
interactions and feedback loops with that approach so I'm not 100% sure
it's working perfectly. I'll probably take the updated version Christian
worked on for a spin soon and see if I can fix the remaining niggles
like this.

Also please look at another "master channel" issue.

For example Analog output selected. You press hardware volume buttons on laptop or change volume using tray icon - volume of analog output changed, everything is fine.
If you select digital output as main channel in KMix, you get this result: change volume using hardware buttons is work as expected, but if you click to KMix tray icon, you will see Analog output volume slider.

I tested a nightly compose of the F15/rawhide kde spin and see that
phonon now correctly prefers the internal audio device to the hdmi
output (from the amd integrated graphics). But the kmix master channel
is still the hdmi output.

phonon-4.4.3-2.fc15.i686
pulseaudio-0.9.22-1.fc15.i686
kdemultimedia-4.5.85-1.fc15.i686

Yeah this is still an issue at the moment (certainly I've not fixed it
personally). There was an issue with this before, that made it
complicated, but I can't remember what it is off the top of my head :s
Hopefully I'll get around to fixing this properly soon.

Looks like KMix didn't save selected main channel to kmixrc
configuration file.

Yes, I had the same issue. I simply switched the primary channel from
master to another and back to master. Then the audio through master
finally worked!
