No sound due to no Linux sound driver...
You can currently only play audio using openMAX (which no games will support).
The good news is I"m working on an ALSA driver, and it"s starting to show signs of life.
Hopefully finished in a week or so.
speaker-test and aplay make recognisable noises. Can"t persuade Quake 3 to even open the driver though. I believe that"s a tricky one to configure even with a working sound card.
Great news about ALSA, what is the process of converting it for ARM and RPi?
You think Jack is a possibility, or not suited to the RPi ; -)
