I fixed two bugs related to sound yesterday. One affected all the systems other than ubuntu and debian. The other affected all systems. I suspect you may have to wait till …. today (today is the SRU day) to see this fixed. > * On joystick input: > I guess that's some of the udev errors, do you have such interfaces planned?
