Have to kill pulseaudio after boot the get audio to work

Question

I have a Logitech G35 USB Headset and I have this annoying problem where I have to kill pulseaudio with "pulseaudio -k" to get it to work for most apps.
Audio only works right after boot in a few apps, like VLC and Firefox with Flash Player (e.g. youtube). But for most other apps, like Chrome, Amarok, Spotify, etc. I have to kill pulseaudio first.
I've read the wiki up and down, my USB headset is set as default audio device and I have no external speakers I user.
Here is some output that might be relevant:
aplay -l:

Even "pacmd list-sink-inputs" will show something, when I for example open a Youtube video with Chromium, which will then play the video as an HTML Video element:

Also, "pulseaudio --check" will never ever output anything. Is this normal? What kind of output should I get?
I think something is wrong with my pulseaudio, but I'm unable to fix it. I'd appreciate any hints and leads! Thanks

Try moving to a backup folder any pulseaudio related .desktop files from the '/etc/xdg/autostart/' folder and reboot see if you still have to kill pulseaudio still.
