I guess route plugin used by RME96*.conf does not support mmap when there is
channel conversion since minimum channels supported by hdsp is 14
static struct snd_pcm_hardware snd_hdsp_playback_subinfo =
{
.info = (SNDRV_PCM_INFO_MMAP |
SNDRV_PCM_INFO_MMAP_VALID |
SNDRV_PCM_INFO_NONINTERLEAVED |
SNDRV_PCM_INFO_SYNC_START |
SNDRV_PCM_INFO_DOUBLE),
#ifdef SNDRV_BIG_ENDIAN
.formats = SNDRV_PCM_FMTBIT_S32_BE,
#else
.formats = SNDRV_PCM_FMTBIT_S32_LE,
#endif
.rates = (SNDRV_PCM_RATE_32000 |
SNDRV_PCM_RATE_44100 |
SNDRV_PCM_RATE_48000 |
SNDRV_PCM_RATE_64000 |
SNDRV_PCM_RATE_88200 |
SNDRV_PCM_RATE_96000),
.rate_min = 32000,
.rate_max = 96000,
.channels_min = 14,
.channels_max = HDSP_MAX_CHANNELS,
.buffer_bytes_max = HDSP_CHANNEL_BUFFER_BYTES * HDSP_MAX_CHANNELS,
.period_bytes_min = (64 * 4) * 10,
.period_bytes_max = (8192 * 4) * HDSP_MAX_CHANNELS,
.periods_min = 2,
.periods_max = 2,
.fifo_size = 0
};
