Ssh – How to forward sound over VNC

audiopulseaudioremminassh-tunnelingvnc

I use TightVNC and Remmina Remote Desktop to connect my Raspberry Pi to my Ubuntu laptop over VNC. It works great for the most part, except for the fact that there is no sound.

I have googled all over the place, looking up forwarding sound over VNC, sound over VNC via SSH tunnel, sound forwarding via PulseAudio Network Transparency. I can't find how to do it.

Does anyone know how to get sound over VNC?

VNC does not support sound.

You can use PulseAudio to move sound over SSH, though, which may be better than nothing for you.

SSH Reverse Tunnel – Remote Desktop Over SSH to Replace TeamViewer

Can you try doing the second step without doing the nc? That is - do the VNC with just the -L and -R. I believe the issue is that your netcat session is connecting back to an already open. So when doing the VNC stuff don't use netcat.

SFTP – How to Use SFTP Over Reverse SSH Tunnel

First, this is a prerequesite (at least for me): Remote desktop over SSH reverse tunnel to replace TeamViewer

The reverse SSH tunnel looks like this:

laptop(SFTP client)--->nat--->middleman<--nat<--desktop(SFTP server)

On laptop edit ~/.ssh/config and add this:

Host SftpToDesktop
  HostName localhost
  Port %p
  User admin
  PasswordAuthentication no
  IdentityFile ~/.ssh/my_id_rsa

Then, with an existing SSH leg from laptop to middleman established already (as per above link), do the following:

$ ssh -fNL 1234:localhost:1234 -i ~/.ssh/some_id_rsa admin@middleman.com

Finally, open Dolphin (if using KDE like me) and enter this location:

sftp://SftpToDesktop:1234
