Hi,
the attached patch adds support for float and double output in audiotestsrc.
Apart from weird clipping with
audiotestsrc ! audioconvert ! alsasink

everything seems to be fine.

Not sure what the clipping causes, when writing the sound to a file all samples
look fine (but are going over the full range of possible values instead of
keeping a bit space around the borders). Lowering the volume of audiotestsrc
also helps, output to int16 and then converting to int32 works too... so no
idea :/
Using osssink instead does work too so maybe alsa simply can't cope with values
going over the complete 32 bit range?

Bye
