I am running Fedora 16 on an Acer Aspire 1410. It has analog jacks for
mic/headphone and a fullsize HDMI connector. I can thus output both video and
audio to an HDTV.

Sometimes when I plug into HDMI and ask gnome-control-center to switch the
hardware's profile from "Analog Stereo Duplex" to "Digital Stereo (HDMI)
Output", it doesn't work. You don't actually get sound on the output, and if
you click the "Test speakers" button gnome-control-center dies with as
segfault.

Sometimes, it's the other way around. For example, this is what I recall has
happened in the last 12 hours:

1. Plugged the laptop onto an HDTV's HDMI cable. Screen turns on automatically,
and I disable the laptop screen.
2. In gnome-control-center, change the hardware profile from "Analog Stereo
Duplex" to "Digital Stereo (HDMI) Output"
3. It works! Grab some popcorn.
4. Unplug the HDMI cable and forget to care about audio for a few hours.
5. Try to watch some youtube video. "Oh snap, it's still on HDMI audio"
6. In gnome-control-center, change the hardware profile from to "Digital Stereo
(HDMI) Output" to "Analog Stereo Duplex". Reload the youtube tab, no joy. Close
the browser and reload it, no joy.
7. Go to gnome-control-center's sound prefs, click the Test speakers button,
segfault.
8. alt+F2, "pulseaudio -k && pulseaudio -D"
9. Hardware profile switching now works.
