SoapySDR::Device::readStream timeout! Rsp1

[kevtheskin]

Morning, I am running Openwebrx + and getting a lot of SoapySDR::Device::readStream timeout! and failing to start. I can see my device using
radio@openwebrxplus:~ $ SoapySDRUtil --probe="driver=sdrplay"

@kevtheskin - you may want to try to run SoapySDRUtil in stream test mode to see if SoapySDR is able to read the sample stream from your RSP1.

The command to do that is:

SoapySDRUtil --args="driver=sdrplay" --rate=2e6 --direction=RX

The output from that command should look more or less like this:

Stream format: CS16
Num channels: 1
Element size: 4 bytes
Begin RX rate test at 2 Msps
Starting stream loop, press Ctrl+C to exit...
1.8881 Msps	7.55242 MBps
1.94578 Msps	7.78311 MBps
1.96186 Msps	7.84745 MBps
1.972 Msps	7.88801 MBps
1.97806 Msps	7.91223 MBps

If you see timeout errors or the sample rates are very different from what I see here, then we probably need to troubleshoot what's going on with your RSP1.
On the other hand if this test is successful, then we should take a look at the SDR client application you are running there to see where the problem might be.
