Right now I think the source is set arbitrarily via pa_stream_connect_record(..., source, ...) where source is nullptr at startup (which pulseaudio defines as setting the source as the system pleases). In my system this sets it to my audio monitor (alsa_output.pci-0000_00_1f.3.analog-stereo.monitor). We should figure out how to set the default input to the default source on startup.
While super clunky (as with everything in pulseaudio xD), one option is to get this via pa_context_get_server_info which triggers a callback including the server info which includes the default source name:
Another option is to set source = "@DEFAULT_SOURCE@" on startup, but when the default source gets set to magic mic, then this would also change. So if we did this we would want to immediately read the current source and then reassign it to the actual name.
Alternatively, to ease this issue, we could simply hide monitors so in cases where users only have one non-monitor mic, the default is correct. For reference, the output of pactl list sources for me is:
