get_sound_input_cap_parm - Detects if the specified recording parameters are supported. Allegro game

       Checks whether the specified recording frequency, number of bits, and mono/stereo mode are supported (and
       how) by the current audio driver.

       get_sound_input_cap_parm  -  Detects  if  the  specified recording parameters are supported. Allegro game
       programming library.

       The function returns one of the following possible values:

          0  = It is impossible to record in this format.
          1  = Recording is possible, but audio output
               will be suspended.
          2  = Recording is possible at the same time as
               playing other sounds (full duplex sound card).
          -n = Sampling rate not supported, but rate 'n'
               would work instead.
