I have found a temp solution for the ringer volume.
go into terminal as root
devel-su
password: rootme
then type alsamixer

keep pressing right until you see PreDriv.
press 'k' to increase to 100, press 'j' to decrease.
press 'ESC' to quit.

This increases the ringer volume by quite a bit, although it is slightly distorted. Still better than missing calls!!!!

Apparently upon reset alsamixer resets itself so some script is needed to adjust this on startup. If anyone can help with that it would be awesome!
