ALSA_PCM_NEW_HW_PARAMS_API etc. is for use with alsa0.9.x
That define is assumed to be the default for alsa1.x.x

ALSA_PCM_OLD_HW_PARAMS_API is for use with alsa1.x.x to make it behave 
like "alsa0.9.x without the ALSA_PCM_NEW_HW_PARAMS_API".

Summary: -
To make your code work with bother alsa 0.9.x and 1.x.x, use 
ALSA_PCM_NEW_HW_PARAMS_API etc. and then write your code to the 1.x.x api.
