I just bought a ppa card myself, because it's easier to chase the small gains first and hit the off ramp later. Don't have it yet, but this thread is pretty interesting.
Is it linear ??? If it's switched it's no good to use .

To put back the USB and compare the USB to rj45
Offramp. Both with the new PPA USB card

Good morning
I have been in contact with Steve regarding the the rj45 problem. . It's not the audio gd as if I use both PC board inputs with the USB it works fine. Also the HDMI works fine.
Now Steve says if the HDMI works the rj45 does. This leaves me to think the cable is damaged. When I test the cable with a data tester it shows only two pairs have continuity and one pair is shorted to another pair. . If I try a regular data patch cable it does not work and gives me a whinnying sound. So dacladder do you have the pinout for a cable . I will make my own to try out . If it works Steve will have the cable repaired . Steve says the cable should have 4 pairs being used ,so it seems the cable is bad . And making my own cable and having it work will prove this.
