Hi all-taht-are-helping-me :)

...I am currently facing more fundamental problems. Background:
I run an Orange PI PC (Allwinner H3 quadcore, 1.2GHz), which has
an HDMI connector, but this would mean an additional cable. Since
the Orange PI PC cannot be powered via USB, currently there
is a power cable and an ethernet cable around here (next is to 
replace the ethernet cable by a wlan connection, but first I need
some sound...)

The traditional ssh -X user@host and then starting a X-applications
runs quite well and even monsters like open office are quite
useable...until those applications with sound.

I tried xpra and (with your help! THX! :) it is spitting warnings
and is to slow even when using application, which do not create
sound.

I dont want pulseaudio. I tried that several times on my dekstop
Linux PC and it screws up things for reasons unknown to me. I will
not exclude the person in front of my monitor as one of the sources
of those problems...but why to give it another chance.

Jack-net isnt available fon Armbian as server application (Armbian
is running on the Orange PI PC).

I dont like HDMI since it is a monitor thingy and does not integrate
into the desktop well, since it is a physical switch. 

Any other chance to get X11 talking to me without any addtional cable?

Best regards,
Meino
