I tried my RTLSDR V4 in the RTL-FM receiver menu and found that it would not receive anything.

I borrowed a V3 and it worked.

I am assuming that this is a driver issue between the two versions.. is there a fix?

Is there a way to turn on/off the Bias-T voltage for external filters and amps?

Also, the volume is far too high for my speakers, is there a volume control for this section?

The RTL-SDR V4 uses different drivers and is not supported by Portsdown.

The facility was designed to be used with external computer-style speakers with a hardware volume control, so it is fixed volume.

Thank you for the information Dave.

I will try to exchange one of my V4s for the borrowed V3.

I will also try to dig up some small PC speakers.
