Installed version 12 and so far so good, except for a small problem that is still mine.
I can't hear through the PHONES direct output. I only listen through PC. Any suggestion??

Hello.
I had the same issue after upgrading to 0.12 alpha. No audio from headphones connected to SunSDR2 DX but it was working from PC.

Check if you are running the latest firmware. I think it should be 78.8.

When I initially upgraded to 0.12 I was not prompted to upgrade the firmware. I suspect it was the desktop firewall. I did the firmware upgrade from another PC from to 78.8 and all seems to be well now.

I hope it helps

Then perhaps your issue is different, but after I did the firmware upgrade Alpha version 0.12 works on any selected sample rate including 312Khz with headphones plugged directly into SunSDR2 DX.

That seems to be thesame on my Sun SDX2 DX. Only works with low samples for audio out.
