Part Number: TAS2563YBGEVM-DC
Hi Sirs,With the same TAS2563 CFG of 0x98+0x9A and 0x9C+0x9E. The TAS2563 EVM works with slve addresses of 0x98 and 0x9A, but no sound with 0x9C+0x9E.The TAS2563 devices can send ACK with the 0x9C and 0x9E, Class-D PWM is running but no sound.Would you pls review the encosed CFGs to provide tips to bring up the TAS2563 with 0x9C and 0x9E?We generated 0x9C and 0x9E codes with PPC3 GUI:0x98 + 0x9A Hardware Setup - Ext I2S ASI. I2C ACK + Class-D amp works normallyClass-D PWM waveforms - Sounds normally0x9C + 0x9E Hardware Setup: - Ext I2S ASI. I2C ACK, Class-D PWM is running but no sound Class-D PWM waveform - No soundThank you and Best regards,Wayne Chen09/15/2020 0x98+0x9A CFGTAS2563_Stereo_Test_0x98_0x9a_48KHz_EC_BIN1_Fullset.cfg0x9C+0x9E CFGTAS2563_Stereo_Test_0x9c_0x9e_48KHz_EC_BIN1_Fullset.cfg
We will take a look at this and will answer as soon as possible.

It is most likely devices with address 0x9C and 0x9E are expecting data in slots 2 and 3, which are not being used. Default configuration for RX time slot is "Mono with time slot equal to I2C address offset".
Can you try to select slots 2 and 3 instead of 0 and 1?If needed I can provide some procedure to test this.

In reply to Ivan Salazar:
Hello Ivan,Thanks a lot. Would you pls provide tips to program the time slots and I2C commands to rework CFG?Thank yo and Best regards,Wayne Chen09/16/2020
In reply to Wayne Chen (ODM FAE):
You can add a command before taking the device into active mode:
Thank you Ivan, It works with the enclosed configuration...Wayne ChenTAS2563_Test_9C9E_0x9c_0x9e_48KHz_EC_BIN1_Fullset.cfg
