I've installed SDRAngel v5.9.4 from the .deb package in 20.04.
It's most likely something I'm just not understanding, but I've added a device (rtlsdr), a file sink, and an FM de-modulator. No matter what I click in the file sink area I cannot get anything to record. There's the squelch button, REC, then there's what looks like a old VHS tape (record?) next to the folder.
If I open the folder it's saying save recording. I gave it a name, hit open. I hit what I assume is a record button next to it, nothing happens. Am I missing something and/or doing this completely wrong? Just looking to understand how to record.
Thanks.
