Well the existing coded uses alloca() ... just saw this while compiling
wine (winealsa.drv):

waveout.c: In function 'wodOpen':
waveout.c:582: warning: the address of 'sw_params' will always evaluate
as 'true'

which I know very well, it's from snd_*_alloca() macros,
snd_pcm_sw_params_alloca() is this case.
