[gentoo-user] "X11 forwarding" so to say ... but for audio

Hi,

I am experimenting with microcrontrollers, dev-boards
and other stuff a lot.
Nowaday these "post stamps" are quite capable and often
run linux of some kind.

The beaglebone and the Orange PI PC are of those, even
running an X11 server.

X11 forwarding is quite handy in this cases...but I miss the
audio.

I am already tangled up in cables ... and dont want to add
just another cable to route the audio signal to my PC.

Is there any other way to get the audio from the (in this case)
Orange PI PC board to my PC in a way, that dont need cables
and is easily reconfigurable, if I will change the board
to something different?

Thanks a lot in advance for any help!

Best regards
Meino
