I've been having really annoying problems with sounds; playing a sound almost always completely and utterly locks up my pi. No cursor movement, no response via any remote shell (from my iMac for example), nothing. I have to power-off and restart. This seems finally to have buggered my SD card, leaving me to rebuild a new one and find all those packages I had installed.
I'm interested to know if it is just my machine, indicating some possible file corruption before-hand, or if it happens to anyone else, indicating some sound related software issue. Or indeed anything else that might help work out what on earth is going wrong.
I have good evidence it isn't anything to do with my Scratch code changes since the system works perfectly well on OSX & RISC OS. That almost certainly rules out corruption of the sound samples for example since the same project files are used.
Of course, hints for a way of avoiding the impolite power-off-power-on cycle would be welcome too. Is there some magic key I ought to be pressing to kill my errant process?
