>>> 2, Can I change MCLK frequences to 12 MHz while frame rate is 44,1 Khz?
Do you really mean 12 MHz? or 24 MHz?
Normally systems running 44.1 kHz frame rates use an MCLK of
44.1 kHz * 256 = 11.2896 MHz, or,44.1 kHz * 512 = 22.5792 MHz

If your BCLK and WCLK are up the spout, then the CODEC will not be
synchronised to the audio stream and you'll get something that sounds
like static instead of the intended waveform.
Tak
By noise, do you mean analog background noise or digital related noise?

It's been a long time sin
Hi all,
I'm try to use TVL320AIC3254 Codec with Beaglebone Black via I2S bus. At
present, I can play music but it hear noise. Attached is script to set up
this codec with these setting: WCLK=44.1Khz, BCLK=1.4112 Mhz, MCLK=24 Mhz.
I have some questions:
1, Below is my hw_params. I want to set B
