Re: Stream Audio Using VNC Command Line to Local Network #audio

Paul Noa

I am reaching out for a little direction getting started with my Draws (Hat Only) install on RPi 3 B+ as I see you are very active and obviously much more knowledgeable than myself in this area.

The more I  read the more unsure I become as where to start. This is where I have started :
Could you be so kind as to direct me to the best most reliable version of Buster w/NWDR code for the Draws hat if this is not the best place to start?

Thanks in advance for your support,

Where in the command that you gave is the syntax for the USB device you
are using? dsnoop:1 ?

If I use cvlc --longhelp it lists alsa audio devices so I'm guessing you
would replace dsnoop:1 with dsnoop:CARD=udrc

cvlc --longhelp | grep -i alsa-audio-device
