Please include the command lines that you used.
Does it help if you use a different audio codec? (see xpra attach --speaker-codec=help)

server:

xpra start :101 --daemon=no

client (windows, linux):

xpra attach ssh:docmax:password@server:101

everything else left to default (xpra.conf/d from ubuntu package)

the server is running virtual and has no physical audio device (is this a problem?)

edit: i tried all audio codec, same result

Looking at your output, I see:

2017-06-12 01:58:47,721 sound source   - speexdec              oggdemux
2017-06-12 01:58:47,720 verify_started() process=<subprocess.Popen object at 0x7f6151eda0d0>, info={}, codec=unknown
2017-06-12 01:58:47,721 sound source * opus :
2017-06-12 01:58:47,721 Warning: the sound source process has failed to start
2017-06-12 01:58:47,721 sound source   - opusenc

So the timeout fires whilst the sound source process is just starting up.
Is this a really slow / low-power system?

You may be able to get it working with:

XPRA_SOUND_START_TIMEOUT=20000 xpra start ...

This will allow 20 seconds before checking for sound source startup timeout.
Note however that sound will be out-of-sync and unreliable on a system that is too slow to startup within a resonable amount of time.

XPRA_SOUND_START_TIMEOUT=20000 did it! And i spend so many hours :-(

Yes indeed, the system is slow and low-power. But it works now. The sound sync is acceptable.

Thank you!!!
