RSP1a found but not running on SparkSDR

[G4SDG]

Hi all. 

I've been using an RSP1a for a few years with SparkSDR and SparkSDR-2 on my Windows 11 i7 NUC with no problems but now although they find the RSP1a it will not function. The log shows :

[2025-10-20 22:08:17.515] [sc] [error] sdrplay_api_Init sdrplay_api_Fail
[2025-10-20 22:08:25.344] [sc] [error] sdrplay_api_Uninit sdrplay_api_NotInitialised

The same RSP1a runs fine with SDRUno and SDR-Connect on the same PC. 

Any advice gratefully received please.

Hi Chris,

do you know what version of sdrplay api is installed?

Thanks for the quick reply Alan. As far as I can see by looking at the docs folder in the Program Files/SDRPlay/API directory it's v3.15.
