In theory, this chmod shouldn't be needed, this is probably 
console-kit's fault... getfacl should show your user as being granted 
permission here... Oh wait, you are using system mode right? Then 
perhaps the pulse user does not have access. Perhaps the pulse user 
should be added to the "audio" group (assuming the files are group owned 
by the audio group.

Ahhh indeed. This is the error I got when running pulse on my PS3! I 
really should have reported this before, but I didn't really play that 
long with Linux on the PS3.

This just proves the device and permissions work. It seems the assert 
above is the real problem.

Well, perhaps, depends what the assert above means :D

Perhaps the right shift is dodgy on PPC arch?
