And if I use an osmocom block (such as provided by osmocom-fft) it works
just fine, so I suspect this is an issue in gr-uhd.

swig wrapper did not get recompiled, and is trying to use the old one.

There was; we now have a tag key for TSB mode.

Well, I was utterly unable to get it to work, using any recent GR paired
with latest “master” of UHD.
I get the same error every time. The swig-generated code “looks”
correct, but this error persists.
I have cleaned every vestige of Gnu Radio and UHD from my system, and
done totally-clean builds and this
happens. Yet, when I use the gr-osmosdr wrapper, it works just fine,
which suggests that it’s in the
SWIGging that happens for gr-uhd.

FYI: The cause of this might be tagged stream support Sean and I added a
while back.
gr-osmosdr uses the legacy setup call, which doesn’t (and won’t) support
TSBs, so this corroborates the hypothesis.

However…

The second of these make calls was changed, and this doesn’t reflect the
changes we did. Will need to investigate. I’ll ping you in IRC when I
get 'round to doing so.
