The Raspberry Pi powering our status screen is also connected to our office doorbell: Everytime someone rings the bell, the Pi plays a short audio file. The Pi features an onboard audio output, but its quality is rather poor. So we decided to use an external USB audio interface instead. But how do we make the Pi use the external interface instead of its own audio output? You’ll find a …

I need a USB audio interface that's good at least at 48 khz (preferably 96khz or better). Using Buster-Raspbian/Linux it must work in the Tx mode when the button MOX is keyed to Transmit from the software GSDR. I'm using this to control transmit and receive, as well as to manage the audio for both, in a SDR-based transceiver for Amateur Radio.

And either comment it: #options snd-usb-audio index=-2
