Buffalo not working via I2S, spdif works

Hi, I am having some trouble with my build. This is what I am building:

- Dual mono buffalo 3 + legato's + ventus for SE output
- Single WaveIO connected to 2x teleporter
- Each teleporter connects to a receiving teleporter which connects to a buffalo.

One halve of the mono setup works great, and both teleporters at the waveIO end are transmitting fine. I have it running at 32/384 and sounds great.
The other halve does not work however, instead it produces nasty digital noise.


This is what I have tried, to no avail:
- Lowering the sample rate of the waveIO to 44.1
- Various DIP switch settings, the default settings do not work not even at the lowest sample rate. If I turn on 'oversampling filter and reclocking' there is no sound at all, not even noise. The input selection switches SW2:1 and SW2:2 have no influence at all.
- Replaced every item, AVCC / tridents / receiving teleporter / firmware / legato, from the working buffalo (except the tridents, I used the older version of those)
- Check and resolder every connection

The board does work with spdif instead of I2S. I2S leads are very short and of same length ~3 cm.

So I have narrowed it down to the DAC board itself. Any ideas? I had already given up hope and have ordered a new board + the new version firmware for all boards, but figured one of you might have an idea how to fix it so I can use for a future project.


Hope you can help :)


Note: I had to bypass 'oversampling filter and reclocking' for it to work at 300+ kHz sample rate. Is this normal behavior? Else I am hearing the same noise as with the other buffalo.

BTW I think this build is unique in a way; I am trying to eliminate as much speaker cable as possible, so I have placed my mono buffalo's near to my mono blocks, close to the speakers. The waveIO+teleporters acts as a central module and the lan cable replaces the need for long speaker cable / interlink cable.
