Getting frustrated by the minute. Searching through
the DIYA posts and TP manuals for 8804Rcvr>Buffalo.
Thought I once saw it but cann't find it now.
How are the jumpers/switches to be set for an
I2S connection 'teew the two? I've tried what
I think the manual seems to hint at with no
sound.
Pretty sure the I2S wiring is correct.
Lights on the WM8804 all light but the
Buffalo is out.

Set the S/PDIF switch on the Buffalo to off (the side marked "1"), and switch 1 on the Buffalo to "-". Then make the following connections:
8804 BCK -> Buffalo DCK
8804 LRCK -> Buffalo D1
8804 DOUT -> Buffalo D2
8804 GND -> Buffalo G

Thanks for the quick reply.
Still no light on the Buffalo.
The WM8804 is setup as
AIF_MS +
TXSRC +
AIF1 -
AIF0 +

Thank you Steinholien for the suggestion. Tried it and :( it did not work. Reconnected the Buffalo with s/pdif input to make sure it wasn't at fault. It's ok. So far have tried, AIF_MS + + + + TXSRC + + - - AIF1 - + - + AIF0 + - + - ..all with S/PDIF switched 1(off) and switch 1 to "-" on Buffalo board. The addr jumper on the Buffalo board is open, i.e. not jumpered. Tried it jumpered also but not with all of the above variations. Wiring double checked with a tug on each one. Even tried SCK(8804out) for DCK(Buff)!? Unit was repowered between each change also repowered cd-player, just incase there is some sort of powerup reset send/recieved. ...just a thought, this was just an experiment to hear if an audible improvement would result from inputting I2S over S/PDIF input to the Buffalo. So, the WM8804 board is wired into the existing stack via 5 inch wires to the Buffalo I2S inputs. Could the long wires be the problem? Edited by user Tuesday, October 14, 2008 9:57:20 AM(UTC)

Quote:The addr jumper on the Buffalo board is open, i.e. not jumpered. Tried it jumpered also but not with all of the above variations. You definitely want this to be open. closing it will result in the Buffalo not booting formware from the uC (wrong bus address). Quote:Wiring double checked with a tug on each one. A better way to test the connections is with a DMM. Continuity from TB pad to TB pad (not from the screw, as that doesn't confirm the TB connection to the board).

Could the long wires be the problem? No. With no signal connected, you are getting the Auto-mute LED to light, correct? And it does work with S/PDIF input?

As noted in the manual on the V1.0 boards D2 and DCK are swapped. So: 8804 BCK -> Buffalo D2 8804 LRCK -> Buffalo D1 8804 DOUT -> Buffalo DCK 8804 GND -> Buffalo G Setup the WM8804 board for 24 bit I2S output and you should be all set. :) Edited by user Tuesday, October 14, 2008 6:19:31 PM(UTC)

I saw the 'PCB Errara:' in the manual last night, but when I saw the 'SDA and SLC' I read right past the second line. ;o( I should have reread it this morning when I wasn't so frustrated. As always, many thanks. Edited by user Tuesday, October 14, 2008 6:30:48 PM(UTC)
