[mythtv] Audio feedback and audio themes

[Dan Schwarz]

So as long as I can't change channels, might as well work on something 
else. :-)

I've been thinking about adding some form of audio feedback to the EPG, 
dialogs, and other UI.  The default would be subtle clicks to indicate 
that the system has received your command (this is especially nice to 
have when using an IR remote).

You could have different sounds when the user clicks "OK" or "Cancel". 
 If any of you are familiar with WebTV, I'm thinking of something along 
those lines.  You hear clicks and soft "thumps" in response to your 
actions.

Audio feedback would be globally enabled/disabled in settings.txt.  I 
don't think audio feedback would be appropriate when watching TV or 
listening to MP3s, so it won't be provided in those modes.

The sounds would be .wav files and would be integrated as part of the 
themes so you could switch at will.

Comments? Is anyone else working on something like this?  What's the 
most appropriate way to play .wav files within mythTV?  If there's a 
library function I can call to do this, great. If I have to call out to 
an external program, not so great. I've been looking at QSound::play but 
it seems to depend on some weird network audio system.
