Questions around Sound Preferences

My Sound Preferences used to have two "Analog Out" entries under Output, one of which had "Headphones" noted in a bottom pane, and the other "HDMI". So I had to select the HDMI option.

Now, I get two BCM2835 options, both Mono. One is headphones, and one is HDMI. HDMI is now the default, and it is also set to Mute by default also. There is no longer any bottom pane, just a single section under "Outputs".

I no longer have sound coming through YouTube on my internet browser, but ScummVM is working. I used to be able to see which Applications were outputting sound on the "Applications" tab but that is always blank now.

My questions are two (actually I have more than two but these will do);

A) Why would my Output tab's contents have changed? I don't believe I did anything to prompt it.

B) How do I save unmuted as a default? Update: it does seem to save unmuted, until I open the Sound Preferences again, at which point my applications will be muted immediately. Still quite strange though.

Thanks!
