Hi Terry,

I have just tested and can confirm that I do have audio. Tested WBFM and NBFM.

I am also using PD4 version 202303290, RTL820t2, the white USB audio dongle.

In Menu 3, Audio out button, have you selected usb dongle and not the RPi output jack?

Hi Terry,

please disregard my comment about selecting the USB Audio dongle.

If a USB audio dongle is connected, the audio output is from the USB Dongle (this allows continued DATV transmissions without a reboot). If no USB Audio dongle is detected, the audio output is from the RPi 3.5mm jack. In this case, the RPi needs rebooting before it can transmit.

I did not have to change squelch or gain settings, all working well.

Wolfgang.

Thanks for confirming Wolfgang.
RTL band viewer is not working for me also.
I checked the RTL on sdr++ and its ok there.
So I'm stuck for now. forcing an update didn't work.

Unfortunately I cant find another RTL to try.

There are many different types of RTL dongle. Not all of them work.

Hi Terry,

if you are not getting the 'No RTL-SDR Connected' error on both RTL-FM receiver and RTL-Bandviewer
then the software has at least detected that there is an RTL Dongle connected.

I have been doing some testing and have found that one of my Noo Elec Dongle Aerial connectors is faulty causing
reception to fail, noise only out of the speaker.

I have tested my SDR Dongles / RX with following results:
- NooElec dongle with R820T2 chipset,
- Two DVB-T+DAB+FM dongles with R820T chipsets,
- Dongle with E4000 chipset,
- RTL.SDR UV HF SDR with R820T2 chipset,
All working with P4 RTL-FM Receiver and RTL Bandviewer.

My old Noxon DAB Stick does not work. (Not Detected). As Mike G0MJW wrote, not all RTL Dongles may work.

Thanks for the comments Mike and Wolfgang
I should of said in my first post that the RTL I'm using is installed in the Portsdown a long time and did work on band viewer and RTL-FM.
Its a DVB-T+FM+DAB dongles with R820T2
I've done two updates since last used and wanted to confirm it wasn't a bug which Wolfgang confirmed.

After lots of plugging and unplugging of usb devices its decided to work on rtl-fm but band viewer gives a black screen and hangs.
I've decided to buy a new RTL, so Wolfgang your list of working devices is very useful to help me choose. Thankyou for testing them all.

I'm happy to Have RTL-FM back as I use it often.
Not working on RTL band viewer is not an issue as I have Lime / Pluto and Meteor view working.
