I found the macro in here https://github.com/analogdevicesinc/linux/blob/adau17x1/sound/soc/codecs/adau17x1.h
#define ADUA_SERIAL_PORT1_BCLK32 (0x0 << 5)
#define ADUA_SERIAL_PORT1_BCLK48 (0x1 << 5)
#define ADUA_SERIAL_PORT1_BCLK64 (0x2 << 5)
But I am strange that on page 55 of datasheet
Table 41. Serial Port Control 1 Register
Bits Bit Name Description
[7:5] BPF[2:0] Number of bit clock cycles per LRCLK audio frame.
Setting Bit Clock Cycles
000 64 (default)
001 32
010 48
011 128
100 256
who is right one ?
I am also puzzle that why the Headphone playback switch is alway on but my lineout switch always off？
numid=14,iface=MIXER,name='Headphone Playback Switch'
; type=BOOLEAN,access=rw------,values=2
: values=on,on
numid=13,iface=MIXER,name='Headphone Playback Volume'
; type=INTEGER,access=rw---R--,values=2,min=0,max=63,step=0
: values=37,37
| dBscale-min=-57.00dB,step=1.00dB,mute=0
There is no script in the filesystem do such behavior.
Can anybody tell me why?
I use PLL, so the core clock is 1024fs =1024*44.1kHz, My MCLK input is 24MHz,
How to set or configure the BCLK? The BCLK and LRCLK of ADAU1961 is master.
Thank you
