hello:
i am faceing a issue about noise when pause the playback
we use omap3730 + TPS65930 :
the codec mode:(Master and slave)
#define SND_SOC_DAIFMT_CBM_CFM (0 << 12) /* codec clk & FRM master */
#define SND_SOC_DAIFMT_CBS_CFM (1 << 12) /* codec clk slave & FRM master */
#define SND_SOC_DAIFMT_CBM_CFS (2 << 12) /* codec clk master & frame slave */
#define SND_SOC_DAIFMT_CBS_CFS (3 << 12) /* codec clk & FRM slave */
when use SND_SOC_DAIFMT_CBM_CFM, we can hear the click-pop noise when playback music. But the last version hardware is ok.
when use SND_SOC_DAIFMT_CBS_CFS(mpu provide i2s-bit clock and frame clock),we can not hera the playback noise, but we can hear a serial of pop noise when we do pause, it will keep the noise in 3s.
why is it?
what is the difference between The master mode and slave mode?
Any one can give me some suggestion?
thanks .
