Dear all,
I'm planning a new DIY project for a digital audio player with good quality SPDIF output.

I decided to use the following configuration
- BeagleBone Black with Volumio
- TPA Hermes-BBB Isolator Module
- TPA Cronus Re-clocking Module
- TPA S/PDIF TRANSCEIVER MODULE (WM8804) to convert the I2S signal to SPDIF.

First of all I would like to know if this kind of solution can provide an high quality digital output.
Second point is to ask some help for the correct working of the project.

I assembled all components and configured the spdif transceiver module as described in the manual for i2stospdif

AIF/MS 1
TXSRC 1
AIFCONF1 0
AIFCONF0 1

Powering all boards:
- 5v on Hermes (the hermes gives the power to BBB)
- 5v on Cronus
- 7.5v on SPDIF transceiver

no output sound. :(

Then I tried to power off the spdif transceiver and it works.
Unfortunately the quality is not good. several clips and audible distorsion comes out.

Do you have any suggestion to improve my project?

Thanks a lot,
Marco.
