nvm, sudo apt-get install python-alsaaudio fixed it!

William, please see if this should be fixed in some way (e.g. handling the 
failure to load the module and just disabling the functionality, or exisitng 
with a nicer message)

Right, the Linux client now depends on python-alsaaudio for the mute sounds 
action. If there's a better way to mute audio on Linux, I'd like to know!

This shouldn't be a problem once I make a .deb that includes dependency 
information. Maybe there's a better way to handle the ImportError for people 
installing from source though...

the mute action doesn't work, I'll see if I can find why. Btw wouldn't it be 
handy to create a deb instead of svn and make it depend on python-alsaaudio?

Hmm, I was worried that the method using alsaaudio wouldn't be portable. I 
wasn't sure what the best way to mute audio programmatically was. Can you tell 
me anything about your Linux system? I tested using Ubuntu 10.04.

Making a .deb is exactly what I plan on doing :). Thanks for being brave and 
checking out the bleeding edge source code!

This seems to work for the sound,

amixer set Master mute

I'm running on a pretty default 10.04 with build-essentials, running on a asus 
eee 1000h.

how about something like this:

    def handle_notification_unmute(self, notification):
        f=os.popen("amixer set Master unmute > /dev/null")

    def handle_notification_mute(self, notification):
        f=os.popen("amixer set Master mute > /dev/null")

    def handle_notification_toggle(self, notification):
        f=os.popen("amixer set Master toggle > /dev/null")

Don't know if this is correct, my python isn't that great. Anyway, this way you 
don't need the alsaaudio lib.

Many modern Linux distros ship with PulseAudio for application-level audio. 
Might be prudent to determine if there's a better way to mute audio as iirc, PA 
doesn't like it when you mess with ALSA directly.

Off the top of my head, it would make sense to depend on the PA library and 
fall-back to ALSA if it doesn't exist.
