The latest version of SDRuno (ver 1.33)is shipping with SDRuno.EXTIO.exe (ver1.05)again included.
So we don't have to keep 2 separate installs

the last version of SDRuno to support EXTIO devices such as the RTL-SDR was 1.22. Remember only SDRuno.EXTIO.exe supports the RTL.. Much like SDR# does not support the RSP.

is that not what happens when you open SDRuno.exe with the rsp unplugged?
Don't you want SDRuno.EXTIO.exe ver 1.1.0.0 last available in the SDRuno 1.2 package and not since.

I just stuffed a fresh one into my sdr#, pick q branch and 5mhz.. presto wwv.

Oh, and the NEW https://sdrplayusers.net/forums/.

why not d/l the HDSDR – V2.76A (13TH JUL 2018) from sdrplay.com/downloads? if I recall correctly, it was documented therein. just pull the EXTIO PLUGINS – V1.2 (13TH JUL 2018).
While the fourm is shut down, everything else is alive and well.

Found my RTL.. Yes Touchstone Pro opens and address an RTL device without issue.

Touchstone Pro from Nutsaboutnets.com is intended for use with the RFExplorer, it does support an RTL-sdr device and the app defaults to the UHF Wireless Audio chunk from 470-600 I don't find my RTL at the moment to cert my statement as all I find at my desk is my Airspy mini and RSP1. oh yes a...
