Hello all. First post here (and I'm afraid it's a problem, sorry.) I've had an N900 since early December - amazing little device and I'm a satisfied customer. Unfortunately today something quite odd has happened, and I was wondering if anyone could shed any light on it.

It seems that somehow the internal audio system has become "locked" - whenever I try to play any audio, either nothing happens or (as in the case of Media Player) I get a message to the effect of "Audio already in use by another application." Rebooting has no effect. I recently had a random reboot I had while using maemo-pc-connectivity, which may be the root of the problem.

Some other odd behaviour too that I think may be related:

- Anyone calling by phone can't be heard
- Calling out by phone forces other caller to speakerphone
- Nokia Video on bootup plays as expected
- /usr/bin/browser hangs at 100%
- Any kind of DNS resolution appears to be broken
- Text message noises etc. are replaced by a system "beep"

I have some extras-devel/extras-testing apps installed. While comfortable with the command-line, I don't know much about the internals of the N900 so it would be great if anyone could point me in the direction of what might be going on.
