Other Parts Discussed in Thread: TAS6424
Hi team.
I'm trying to play 48KHz_32bit_4Ch wav and 48KHz_16bit_4Ch wav now through TAS6424L-Q1.
In the case of 48KHz_32bit_4Ch, there is no problem to listen to it.
But when I test it with 48KHz_16bit_4Ch, there is only noise sound.
When I check it using the internal loopback audio path which is not connected to TAS6424, it seems to be ok.
(These are the dump of TAS6424)

As you see SAP control (0x03), it looks fine.
And when I check MCLK, it has 24575998 Hz (512 x fs)
And SCLK has 3071999 Hz (48000 x 16 x 4 = fs x 64)
Could you let me know what I need to do for the next step?
Thank you.
