What codecs will I need with Lubuntu 12.04 PowerPC

I had to install the older v12.04 of Lubuntu for PowerPC on my Powerbook G4 because I couldn't get the sound to work in v14.04. Aside from all the updates, what codecs and drivers will I need. My video is as follows:

jacatone@G4 ~]$ lspci | grep VGA
0000:00:10.0 VGA compatible controller: NVIDIA Corporation NV34M [GeForce FX Go5200] (rev a1)

Thanks.
