As a temporary workaround, here are the steps needed to fix analog audio on panda:
Open a terminal and type:
sudo alsaucm set _verb HiFi
sudo alsaucm set _verb Record
sudo rm /var/lib/alsa/asound.state
This gets audio out working for me. Audio in is still not functional, but may be driver related (I twiddled every alsamixer control and still didn't get anything).
