Listen to HD radio with a $30 RTL SDR dongle

Thank you for the hard work! Gqrx allowed me to identify the "Alternate Frequency" flag on one of my favorite FM stations that was causing my car to change channel every couple minutes. I was actually able to contact the station and they fixed it!

Ooh, since I have your ear, Gqrx performance is pretty unusable on my Apple Silicon Mac, like 1-2 FPS rendering the charts and the whole UI chugs. It was fine on my Intel Mac.

There any work going into that? I fully understand if it's a QT UI toolkit issue and out of your hands.

There's an issue open for this: https://github.com/gqrx-sdr/gqrx/issues/1104

I could really use some help from a software build expert. Gqrx and all its dependencies would need to be built in CI with Apple silicon support, and I don't know how to do that.
