*
* PulseAudio supports the following sample formats:
*
* \li PA_SAMPLE_U8 - Unsigned 8 bit PCM.
* \li PA_SAMPLE_S16LE - Signed 16 bit PCM, little endian.
* \li PA_SAMPLE_S16BE - Signed 16 bit PCM, big endian.
* \li PA_SAMPLE_U8 - Unsigned 8 bit integer PCM.
* \li PA_SAMPLE_S16LE - Signed 16 integer bit PCM, little endian.
* \li PA_SAMPLE_S16BE - Signed 16 integer bit PCM, big endian.
* \li PA_SAMPLE_FLOAT32LE - 32 bit IEEE floating point PCM, little endian.
* \li PA_SAMPLE_FLOAT32BE - 32 bit IEEE floating point PCM, big endian.
* \li PA_SAMPLE_ALAW - 8 bit a-Law.
* \li PA_SAMPLE_ULAW - 8 bit mu-Law.
* \li PA_SAMPLE_S32LE - Signed 32 bit integer PCM, little endian.
* \li PA_SAMPLE_S32BE - Signed 32 bit integer PCM, big endian.
*
* The floating point sample formats have the range from -1 to 1.
