Once again, my X has stopped from playing any alert sounds at all. It was working this morning, but has been silent for a few hours.

I've seen this in both the Official and Community builds.

Phone seems to work normally, I get audio in both normal and loudspeaker modes in a call. But no alert tones play. Trying to play an mp3 from the file manager is also silent, as is a video from LLsvPlayer.

Tried switching bluetooth off and on in case it was streaming to the car, also tried in and out of flight mode. Also switched ambiences with no effect.

Any of our wise cadre have any other things I can check before I reboot (which always brings it all back).

Not sure what processes I should be looking for or restarting from the console?
