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

Mon, 12 Jun 2017 13:50:56 GMT - DocMAX:

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

Mon, 12 Jun 2017 19:03:37 GMT - DocMAX:

No issues in arch linux.

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.

Mon, 12 Jun 2017 20:55:41 GMT - DocMAX: status changed; resolution set

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!!!
