See /usr/ports/UPDATING at 20140610. INTEGER_SAMPLES should be disabled unless
you build with MOZ_SAMPLE_TYPE_S16 in which case it's not a supported
configuration. files/asound.conf.sample in audio/alsa-lib configures ALSA to
convert FLOAT samples to S16 by default for OSS which works for both
www/firefox and www/linux-firefox.

AFMT_FLOAT is only available on Linux. PulseAudio converts FLOAT sampels to S16
internally while libsndio in libcubeb backend within Firefox.

INTEGER_SAMPLES in audio/soundtouch affects API/ABI, so should be used with
care even with non-gecko consumers. The option is probably only interesting for
architectures where floating point operations are slow (no SSE support) or
emulated (ARM?).
