For some reason, we need to use SGTL5000 DAC in I2S mode.
In my environment, fs=48khz, mclk=256fs=12.288Mhz, sck=64fs=3.072Mhz. VDDIO=VDDA=3.3V, VDDD=1.2V.
We set SGTL5000 in slave mode and SYS_FS=48k, MCLK_FREQ=256fs.
But no audio output.
(Same power supply was ok by using SGTL5000 in master mode by iMX6 driver,
but we change mclk to 12.288 , and using slave mode, no audio come out)
Anyone have the successful to use SGTL5000 in slave mode,
and can give us the setting sequence of I2C command ?
Or can some one can tell me how to debug by some I2C command ?
My SGTL5000 version is 0X11.
HI Kang
one can look at patch below
[alsa-devel] No sound captured with SGTL5000 on i.MX6 in I²S master mode
