No audio from GQRX on Pi 4

[Greg Hemmings]

I am using a Raspberry Pi 4 (Buster) with GQRX. The radio, Airspy HF+ works fine but there is no audio output. I am using Pulse Audio, but I noticed there is a folder for ALSA. Shouldn't it be one or the other? I get great system audio on YouTube and streaming radio. I read about a driver conflict somewhere but I can't find it! How do I make this work? Please remember I'm new and need very specific instructions. :)

Try -

pavucontrol

while you are running GQRX - it lets you select the output device.

you may need to install it first-

sudo apt-get install pavucontrol
