Ok we had a long discussion on IRC about this.  It seems we actually
only had this turned off in Jaunty, it was turned off using
CONFIG_SND_HDA_INPUT_BEEP.  It was turned back on in Karmic and we did
not have issues there.

The original problem was ear splitting frequencies for the PC Beep and
it seems these calculations got sorted and then it could be re-enabled
sounding like a normal beep for Karmic.  In the current setup we seem
to have a codec specific issue in that the beep sounds like mains hum.
This is not universal.  In this occurance the volume slider does work as
expected ie. it changes the volume.  I think we have a whole new bug in
the kernel driver for some specific codecs, Stefan has one which
behaves apparently correctly.

So I think we need a new bug filed for this new issue, if we can get
the current reporter to file the bug we will get the codec information
which would be handy.
