linux, 2 devices - both detected/selected but does not stream

[luoGanda]

this is for prerelease on Apr 8.

With previous(full 3.0 Jul 5, 2022) hackrf works - but sdrplay is not detected(was probably taken out of that release).

With current(Apr 8) - both sdr's are detected - but pressing Start does not stream.
For both - device specific tweaks as usual.

This got printed on terminal when Start pressed for rsp1:

[INFO] devIdx: 0
[INFO] SerNo: 0000000001
[INFO] hwVer: 1

And this is from LogViewer:

Also tried to run with sudo(for perimission problems), enabling/disabling dc correction, but it's the same.
In Signal source -> processing rate it shown 1% and there is an exclamation mark.

This linux ver has not systemd, but SysV Init - but this probably does not have anything to do with it,
since previous release works for at least one device.

Any hints?
