I'm wondering if anyone else has had this same problem, because if so it might be worth while for me to file a bug, but it might also be chaos monkey so I wanted to check first.

I have an Acer Aspire One D257 and the sound worked in 11.10 by default, but after doing a fresh install of 12.04 there is no sound. There used to be a speaker icon on the menu bar but now there isn't, and volume up and volume down hotkeys now do nothing, which leads me to believe it isn't detecting the sound card properly anymore. Googling for sound problems on an Acer Aspire One D257 on 12.04 isn't showing any helpful results, so I'm wondering if it's just me.

Does anyone have an AAO D257 on 12.04 with the sound working, and if so did you have to do anything special to make it work?
