can you check if your earpiece is working? I saw one bad earpiece and i always 
wondered that the small pins have contact.

Anyway you can try this:

	alsactl -f /opt/qtmoko/etc/alsa/a4/PhoneEarpiece.state restore

and then play some sounds - e.g. in media player or from command line:

	. /opt/qtmoko/qpe.env
	paplay /home/root/Documents/Alarm_Beep_01.ogg

It should play in the earpiece.
