HI!
I have a comtom dm6467 board with tlv320aic20k audio chip,
config the tlv320aic20k and record it(arecord) with 8Khz sample rate,
but the sound play back (play back it in windows) with a lot of noise.
MCLK is provided 27Mhz and the FS pin is measured with 8Khz frequency,
I config 8Khz sample rate with regs as follow(M=7 N=15 p=2):
tlv320: addr = 0x00, data = 0x00
tlv320: addr = 0x01, data = 0x49
tlv320: addr = 0x02, data = 0x20
tlv320: addr = 0x03, data = 0x01
tlv320: addr = 0x03, data = 0x40
tlv320: addr = 0x03, data = 0x80
tlv320: addr = 0x03, data = 0xc0
tlv320: addr = 0x04, data = 0x7a
tlv320: addr = 0x04, data = 0x87
tlv320: addr = 0x05, data = 0x00
tlv320: addr = 0x05, data = 0x40
tlv320: addr = 0x05, data = 0x80
tlv320: addr = 0x05, data = 0xc0
tlv320: addr = 0x06, data = 0x01
tlv320: addr = 0x06, data = 0x81
can any one give me some advice?
