New API, new SoapySDRPlay and Ubuntu

[IW2DHW]

I have done some test with new API and new version of SoapySDRPlay and CubicSDR, using my current Ubuntu 14.04 and my test Ubuntu 16.04.1
All test done on my desktop PC, previously running CubicSDR without any problem.

On Ubuntu 14.04/64 bit.

New API is working but new version of SoapySDRPlay is fault. After downloading and recompiling all software, I get this results:

SoapySDRUtil --find
show Audio and SDRPlay

SoapySDRUtil --probe
show only Audio (first device)

CubicSDR freeze on loading SoapySDR modules

API/ABI version and available factory are all correct.
So now I am without CubicSDR on Ubuntu 14.04

On Ubuntu 16.04.1/64 bit.

Apparently all is working:

SoapySDRUtil --find
show Audio and SDRPlay

SoapySDRUtil --probe
show Audio and SDRPlay

CubicSDR find SDRPlay and run it but audio spectrum is too fast and I get random "silence holes" in audio output
This evening in 30' of VOA Radiogram reception, I get this log on starting window:

Code: Select all

Each silence time correspond to a "[CRITICAL] ds_mir_sdr_ReadPacket() error: 1"

As example I attach an image received from VOA, with "hole" on audio reception

Can anyone confirm this problem?

Franco,

where did you find the new soapysdrplay? Is it the one with the transfer mode patch or is it already ported to the new API?

I use new version obtained from GIT with "git pull" from SoapySDRPlay repo.
From commit log I get:

Fix for Ubuntu 16.04 hang

Thanks Franco, that's the version I am running too.

I added support for the ppm correction so I can now match gqrx frequency with my TS590SG.
