TAS2557: Change the clock source by I2C write directly

Hi Team,

We want change the clock source from MCLK to BCLK.

But as we change book00/page01/address74 from 0Dh to 00h, the sound become noisy and quality bad.

Any other register need modified to resolve the noisy? Or If our procedure is wrong?

Test procedure:

1. Use TAS2557 EVM, and open a new mono project on PPC3.

2. System check OK

3. Open I2C monitor and use Log tab start recording.

4. Choose Tuning and Audio Processing---play music, sounds great.

5. Save the I2C log then add "w 98 74 00" below the "w 98 73 0f" command.

6. Stop music, and use I2C monitor I/O tab execute new file which add "w 98 74 00"

7. Then play the same music, sounds become noisy and quality bad.

Thanks
