Sure. This will have to wait till next week, though.

But to me this seems a rather straightforward problem:

typedef enum pa_sample_format {
    PA_SAMPLE_U8,              /**< Unsigned 8 Bit PCM */
    PA_SAMPLE_ALAW,            /**< 8 Bit a-Law */
    PA_SAMPLE_ULAW,            /**< 8 Bit mu-Law */
    PA_SAMPLE_S16LE,           /**< Signed 16 Bit PCM, little endian (PC) */
    PA_SAMPLE_S16BE,           /**< Signed 16 Bit PCM, big endian */
    PA_SAMPLE_FLOAT32LE,       /**< 32 Bit IEEE floating point, little endian, range -1 to 1 */
    PA_SAMPLE_FLOAT32BE,       /**< 32 Bit IEEE floating point, big endian, range -1 to 1 */
    PA_SAMPLE_MAX,             /**< Upper limit of valid sample types */
    PA_SAMPLE_INVALID = -1     /**< An invalid value */
} pa_sample_format_t;

They are the formats that Pulse supports, right?
PA_SAMPLE_S32* should be added to the list.
