Well that capture is taken while the DAM had locked on signal and sound was playing. More to that in the measured setup MCLK was coming out of DAM to the beaglebone black which is slaved on the DAM. Could you please explain what you mean by locking to new clock? (Forgive my ignorance on this but I thought that MCLK should be steady clocking while locked on the signal)

Are you using the BBB I2S output to your DAM?


I was thinking of doing the same set up in a while.

Would you mind sharing your set up BBB which caps are used to connect it to DAM I2S

You can connect them without a cap.

I am getting no sound with 1.03. Seems to lock according to LED though. I get his on power up :

R1.03
I3
L000
F4
V+00
I3
I1
L044

input is via SPDIF via Normundus V1 input board. Power is +10V from Salas BIB. +/-5v analog from another Salas BIB. Mute disconnected (input transistor on mute circuit pulled up with ~ 10k resistor to V+).

Works OK if I revert to 0.99. v1 DAM1021.

Hi,
Can you tell me where did you disconnect the mute circuit? Or about when did this post been mentioned?
Thanks

Firmware version 1.04 is now up on http://www.soekris.dk/download.html

There are now full DSD support, up to DoP128 and DSD256, depending on the used USB to I2S interface.

Pinout for DSD is per de facto standard:

I2S bclk -> DSD Bit Clock
I2S lrclk -> DSD Left Data
I2S dat -> DSD Right Data

The issue on version 1.03 with no output on SPDIF should be fixed now, could people having the issue please report back.

Except these three pins, which pin required to connect for Amanero Combo 384?
"DSD on" on Amanero Combo 384 not required?
The board can identify which signal format (PCM/DSD) to be decoded?

1.04 version fixed the 'no sound' issue, all is well. Thank you Soren :)
