Audio under-run with USRP N200 about shinysdr

The missing waterfall probably means there's something else wrong, but does this sound like #51? In particular, is the audio underrunning in AM mode but OK in narrow FM?

Also, whatever you meant to show in “Here's a comparison…” didn't make it in.

I updated the original post with two links (https://i.imgsafe.org/24f30d9aa4.png

It's similar to the issue #51 (almost always getting underron on FM and AM, but not on SSBs. On NFM, I get underrun once in a while)

OK, so that is probably the same as #51. It's a weird bug, and I haven't gotten around to digging into it yet.

Your waterfall display is working normally — it is just out of range, because the USRP's signal is at a different level than the RTL-SDR's. I can see some small peaks and faint blue in the screenshot. Click on the “Options” at the top right and adjust “Lowest value” until you can see the spectrum.
