2 Mhz samplerate + Bandwidth auto mismatch

[nmaster2042]

Hi.

Usig SDR++ with Soapy source I found there is a mismatch when selecting 2Mhz samplerate while letting bandwidth as Auto.

In logs on console we can read:

[31/03/2024 00:22:18.000] [INFO] Bandwidth for samplerate 2000000.000000 is 5000000.000000

But I think it should be 1.54 Mhz, isn't it ?

To have good waterfall I must select manually BW of 1.54 Mhz.

If I chose sample rate of 2.05 Mhz (actually 2048 khz) while letting bandwidth as Auto, things are going well, we have in logs:

[31/03/2024 00:22:36.000] [INFO] Bandwidth for samplerate 2048000.000000 is 5000000.000000

This seems to be the correct combination in this case.

I used a RSP2, the last SDRPlay 3.14 API and the last SoapySDRPlay driver.
