Sound Card DAC + LFI problem

[djpsych]

I finished building my Sound Card DAC few days ago, tuned the offset to 0V on all six channels with no sound playing and then played the max.wav with the volume all the way up and tuned the gain to +5V on all six channels. Started up the "LFI_Player_V1_1_6_EzAudDAC.exe", opened up the ILDA test patten and hit the play button and I got no voltage change on any of the six channel when I measured with my Fluke 117.

I believe it has something to do with my USB ports not being mapped to COM ports. I tried COM1, COM2, COM3, and COM4. Also every time I hit apply I got this error in the log file:

OnButtonComApply(): COM Setup() failed.

Handshaking is set on Hardware (RTS/CTS), so it is on.

I am planning on getting either Spaghetti or Pangolin FB3 later, but when building I wanted to use LFI Player for the testing. Did I miss something in the LFI Player settings? (Attached pictures and important LFI Player config and log files)

Was your DB25 cable (ILDA) connected correctly from the correction amp to the PC... Im buying parts to build a soundcard DAC myself..

If you have not already done so, Turn on laser emission in LFI player....

That is a common item missed.

Turn off all the 7.1 settings, revert the card to 5.1 surround, turn off any echo processing in the sound card dac setup software, and if you have Win 7 there are issues with the sound card dac under certain circumstances that are not a LFI player issue. There is a good thread at Laser Pointer Forums on this one.

You should not being seeing com errors that you can not just hit enter/click and skip over. Something is possibly conflicting on your USB.

The Aud card does not call USB functions as a com port. Are you running a com port redirector or other custom software?

Please let us know what you find, I am beginning to see the nails in Sound Card DACings coffin.

If you want a better alternative for use with LFI, this works:

Chris might still have some bare boards.
