1.4 Troubleshooting

This section provides a series of solutions for possible problems that can happen while the TAS5830EVM is in use.

  • No audio is playing but the device is on and the outputs are switching
    • Make sure that the I2S jumpers (J27, J28, and J29) are connected to the "bypass" option or that an external PSIA is connected
    • Make sure that the I2S select switch (S2) is set to XMOS if using USB audio or SPDIF if using optical or analog inputs
    • If using USB audio as the input, make sure that the EVM is selected as the playback device and that the volume is set correctly
    • Make sure the device is not muted in register 0x03
    • Probe the I2S signals into the device and make sure SDIN is as expected
  • No audio is playing and the outputs are not switching
    • Read registers 0x70 to 0x73 to check for any faults and make adjustments as necessary. Register 0x78 can be used to clear faults after the faults are resolved
  • PPC3 can connect to EVM but fails to communicate to the TAS5830
    • Make sure that I2C jumpers (J22 and J23) are inserted
    • Make sure that the correct PVDD jumper to the device is installed and power is supplied. This is jumper J18 for external PVDD or J14 for Class-H control
