The sample rates that part can run at depend on the external clock rate. It can run at ext_clk / 256, ext_clk / 128 or ext_clk / 64. Maybe we should just implement it like that. Do you have support for switching the external clock at runtime on your platform? > --- > sound/soc/codecs/adau1701.c | 5 +++-- > 1 file changed, 3 insertions(+), 2 deletions(-) > > diff --git a/sound/soc/codecs/adau1701.c b/sound/soc/codecs/adau1701.c > index de53c0d..8b3ba51 100644 > --- a/sound/soc/codecs/adau1701.c > +++ b/sound/soc/codecs/adau1701.c > @@ -459,6 +459,7 @@ static int adau1701_hw_params(struct snd_pcm_substream *substream, > case 96000: > val = ADAU1701_DSPCTRL_SR_96; > break; > + case 44100: > case 48000: > val = ADAU1701_DSPCTRL_SR_48; > break; > @@ -623,8 +624,8 @@ static int adau1701_startup(struct snd_pcm_substream *substream, > return sigmadsp_restrict_params(adau1701->sigmadsp, substream); > } > > -#define ADAU1701_RATES (SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_96000 | \ > - SNDRV_PCM_RATE_192000) > +#define ADAU1701_RATES (SNDRV_PCM_RATE_44100 | SNDRV_PCM_RATE_48000 |\ > + SNDRV_PCM_RATE_96000 | SNDRV_PCM_RATE_192000) > > #define ADAU1701_FORMATS (SNDRV_PCM_FMTBIT_S16_LE | SNDRV_PCM_FMTBIT_S20_3LE |\ > SNDRV_PCM_FMTBIT_S24_LE) > _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
