TAS5717EVM Speaker no sound issue.

Other Parts Discussed in Thread: TAS5717EVM

Hi Team,

The customer is using TAS5717EVM. 

Hardware settings： JP4 and JP5 are cutovered ADC input.  That is the 1pin to the 2pin can be connected for JP4 and JP5.

 JP11 is  cutovered RCA input. Others are default. The customer uses a 4ohm 5W speaker.

Then the customer installs the GUI software.

Software settings: 1. Changing Windows Environment Variables---PPSI2C is 54.  Use the I2C memory tool to read 0x00 address, and the return value is 6C.

The GUI software are  settings in the attachment . Then the customer uses as the ADC Analog input signal and select the speaker output on the GUI software.

Then there  is not any sound for the speaker.

But if the customer uses the headphone output and connects the 1pin to the 2pin for JP1 and JP2. The headphone has the sound. And the Shutdown  that is on the GUI software is fine, but the Mute  that is on the GUI software is not fine.  That is the headphone cannot be muted.

Q1: Is there any setting error for the customer?   How to set the EVM board and the GUI software to make the  speaker have the sound when the customer select

the  ADC Analog input signal?  I think the 1pin and  the 2pin for JP6 and JP7 can be connected.

Q2: The customer would like to use their company‘s I2S signal on the EVM board. The MCLK  signal frequency is 12.28MHZ. The LRSLK signal frequency is 

48KHZ. The SCLK  signal frequency is 1.536MHZ. The I2S is set 16 bit. Then the customer connects the MCLK、LRCLK、SCLK and SDIN signal lines to the

EVM board, but there is no any sound for the speaker.

How does the customer do if the customer would like to use their company‘s I2S signal on the EVM board and select the speaker output?

Best Wishes,

    Hi, Mickey,

    Thanks for the detailed information. The device seems to be communicating properly with the GUI, so I think the issue is related to the input configuration in MC57xxPSIA board. Please refer to below hardware configuration for the different inputs available in MC57xxPSIA board.

    Analog input (RIN/LIN)

    • Select ADC in JP4 and JP5 (short on pins 1 and 2).
    • Audio CLK jumpers (JP6-JP10) should be connected with pins 1 and 2 tied. 
    • JP2 and JP3 will limit the input voltage:
      • IN: LIN/RIN = 1Vrms MAX.
      • OUT: LIN/RIN = 2Vrms MAX. 


    Digital input (Opto/RCA)

    • Select SPDIF in JP4 and JP5 (short on pins 2 and 3).
    • Audio CLK jumpers (JP6-JP10) should be connected with pins 1 and 2 tied. 
    • JP11 selects the SPDIF source:
      • Opto: pins 1 and 2
      • RCA: Pins 2 and 3


    External PSIA input (I²S)

    • Connect the PSIA clock signals to pin 2 of Audio CLK jumpers (JP6-JP10).
    • Connect the PSIA GND to pin 3 of Audio CLK jumpers (JP6-JP10).

    Please check with customer if the configuration is correct in the MC57xxPSIA board for the desired input type.
