This is my build of the board with iso7240 from texas.
I test it just now.
The input of the isolator has 3.3V supply from the amanero board . It measure about 3.2 on the isolator board. The output of the isolator has a 4.8V power from another source. The amanero usb i2s board is powered from the usb input itself.
There is sound but music is very soft with very prominent background hiss that correspond to the volume pot.

what are the likely problems ?
I appreciate input from more able diyers .
thanks

Hi peterpopo,
I power the input segment of the iso7240 by another power power supply with 4.7 V dc . the hiss disappeared and sound quite nice in my test speaker but there is intermittent dropout that may be due to cold joint. will troubleshoot after work tonight.
i think the 3.3 v from the amanero combo board is not enough to power the isolator.
thanks

I redo the joints and the intermittent drop out persisted.
Could the drop out due to intermittent unlocking of the i2s signal ?
Any suggestions anyone ?
Have anybody use this isolator successfully with the Buffalo 2 dac ?
I may populate the other board at a later date if there is no other suggestions .
