Right from the start when I got my MB1 I noticed a very low audio output in the internal speaker. I always have the volume at 100%, and even then it's waaay too low. I just thought it was a software setting, so I did not bother about it. But as time went by, I could not figure out any way to make the sound output higher. Emailed EE some time ago, and Roman suggested that I should measure the AC voltage over the internal speaker terminals. Not done that yet.
Anyway, I tried connecting my ICOM SP-20 at the rear mini-jack, but same problem. Very low audio. Since I operate 99% digital modes this has not been a high priority to fix for me. But now Es season on 6m is coming up, and some SSB QSO's would be nice
So today I hooked up an active studio monitor speaker to the rear mini-jack. But now I can't get sound at all. Tried the front headphone jack, still no sound. I have tried every possible setting (I think) in Win10 and in the ESDR2 Sound Card menu.
I do not have bad hearing
