There are three possibilities I can think of here...
The first, and most likely is that one of the audio apps crashed and took out the audio decoder with it. If that happens, you would see what you're reporting in MPlay (video but no sound). Try rebooting the PB by holding down the power button on the front of the unit for a few seconds until the light flashes. Once it boots back up, try MPlay again and see if you get audio.
The second possibility is that the "Listen" application (Sonata) still has the audio device open. It's not at all straight-forward how to stop Sonata once it's started. If the "Listen" application in the main Roku UI has a "play" icon on it, then Sonata is still running. Highlight it and press the play/pause button on the remote to stop it.
The third possibility is that an application has set the volume low on the PB. Specifically, SlimRoku sets the volume to whatever SlimServer is set for (upper right-hand corner of the web interface). If that was set low when you ran SlimRoku, then SlimRoku crashed, it's possible that the PB has maintained that volume level. Try launching SlimRoku, then go to the SlimServer web interface and set the volume to "11". Then exit SlimRoku gracefully.

I believe lossy AAC should be supported natively by the 2.0 firmware. soiaf has written a number of third-party audio codecs (including one for lossless-AAC) that work with the 2.0 firmware. I don't know if there is a comprehensive list anywhere, but he's pretty much written one for all of the major formats. Do a search in the third-party forum for "codec" and you should get them in the results.
As for video on the PB, MPEG-1 and MPEG-2 are the only natively supported formats.
