OK, from the output, I can see that you are indeed running the appropriate hardware driver. As to why you’re getting poor performance, then, it’s hard to guess. Maybe it has something to do with this:
do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
Try adjusting the vblank_mode configuration parameter. That message isn’t generated by Panda; it must be coming from your graphics driver. I’ve never seen anything like it before. It suggests you should try adjusting vblank_mode, though, which means you should try putting:
sync-video 0in your Config.prc file.
I don’t know about your audio issues, though. Maybe there are permissions issues on your audio hardware, or maybe there is another application running that’s keeping the hardware locked? Try shutting down any other audio applications. Or maybe you can enable software multiplexing in your system audio settings?
