Is there a way to list sndio endpoints?
Unless someone has a better idea, I think you need to look at your dmesg.
Look for lines "audioN at whatever". The audioN device should correspond
to a (r)snd/N sndio device. AFAICT the rsnd/N devices are always
accessible if a corresponding audioN device is available. The snd/N
devices are made available by sndiod.
If you have multiple audio devices I think it's necessary to specify them
in /etc/rc.conf.local in order to make them available through sndiod.
e.g. sndiod_flags="-f rsnd/0 -f rsnd/1"
Specifically I was trying to attach a scope(probably one of the ffplay
visualizations) to the main output. however I could not figure out what
endpoints exist.
I don't know if this is what you want, if I connect my USB camera I'm able
to get a visualisation by tapping my finger on the camera while running:
ffplay -f sndio snd/1
Big thanks for all the help.
It was just a silly idea that I had after reading sndiod(1)
"I bet I can get the spectrogram in ffplay to show my system sound"
I knew it should be easy, unfortunately I was unable to figure out what
to read to get ffplay to display what I wanted.
So, while the question was stupid and the answers were simple, that was
exactly what I needed to start doing more than just passively using sndio.
