Soekris DAM1021 and Amanero I2S - No Lock

[vdi_nenna]

Hi All,

Just put together the latest Soekris dam1021 DAC with Amanero I2S USB adapter. Not getting a lock.
Using this page as a build reference. https://hifiduino.wordpress.com/2015/03/16/soekris-dam-1021-r-2r-dac-users-guide/

- J2 Voltages are ok. Using adjustable voltage reg set to 10v dc.

- Supplied 3.3v from Amanero I2S board to DAM1021.

- Audio output taken from raw L&R.

- Music server Daphile software recognizes the Amanero combo board and Amanero is able to be selected in the Daphile software.

- Default auto-select of source in use.

- Tried 3 different USB cables, all non-audiophile type, probably USB 1.1.

- Tried 16 bit and 192 bit music tracks.

Are the isolated grounds on Amanero boards pins 13,14, and 15?
Does the lock happen only when it detects a track or the dam1021 detects a source?

Any tips would be helpful,

Thanks,

Vince

Added dedicated regulated 3.3v to dam1021 isolated side. Still no lock.
Twisted all pairs. No lock.

Locked for a few minute on Windows, with Windows driver. Lock is eventually lost.
Music tracks played faster, as if sped up. How's that even possible?

I've read that Amanero board isn't the best fit. Anyone have this experience?
Can anyone recommend another USB to I2S adpater board? DIYinHK??

Is it possible the firmware needs updating? This board is the latest from Soekris.

Any help would be appreciated.

Thanks,

Vince

Make sure your Amanero firmware is recent and is set to 32bit output.

Thanks, I got the answer on another thread. Works fine. Also updated to dam1021 firmware 106. Plays DSD files now.

Thanks

Amanero Soekris no lock

Thanks Rene

The solution was to update the firmware on both the Amanero and the Soekris units. It's also important to keep the leads between units short to around 3 inches.

"The boards by default are programmed with CPLD_for_1080 and firmware DSD512x48x44"
