Can't totally confirm, but the driver for the BCM2835 says this.
It looks like 16bit to me.
Code:
--------------------
/* hardware definition */
static struct snd_pcm_hardware snd_bcm2835_playback_hw = {
.info = (SNDRV_PCM_INFO_INTERLEAVED | SNDRV_PCM_INFO_BLOCK_TRANSFER |
SNDRV_PCM_INFO_MMAP | SNDRV_PCM_INFO_MMAP_VALID |
SNDRV_PCM_INFO_BATCH),
.formats = SNDRV_PCM_FMTBIT_U8 | SNDRV_PCM_FMTBIT_S16_LE,
.rates = SNDRV_PCM_RATE_CONTINUOUS | SNDRV_PCM_RATE_8000_48000,
.rate_min = 8000,
.rate_max = 192000,
.channels_min = 1,
.channels_max = 8,
.buffer_bytes_max = 128 * 1024,
.period_bytes_min = 1 * 1024,
.period_bytes_max = 128 * 1024,
.periods_min = 1,
.periods_max = 128,
};
