Ringtones

/usr/share/hackable1/h1.pa contains the path for both the ringtone and the sms notification.

Warning: Only use tiny .wav files (for instance, the default ringtone's size 1.1M)
Warning 2: As the timeout for the replay of the ringtone is hardcoded in phone-kit, you should avoid setting a ringtone that is longer than 12s: this could cause overlapings. This will probably fixed in rev6.

To apply the modification, you can either restart pulseaudio as hackable1 user:

$ pulseaudio --kill && pulseaudio -D -F /usr/share/hackable1/h1.pa

(there will be a non-fatal warning)
or reload the samples (still as hackable1 user):

$ pacmd
>>> load-sample <ringtone or message> /path/to/the/sound

(control+d to exit) (you can also use these commands to test if the sounds are valid)
