re: #363 - my monitor source was muted and so I didn't get any sound. xpra should help debug lack-of-sound, and maybe tell you that the source is muted or volume is very low.
pactl set-source-mute alsa_output.pci-0000_00_1b.0.analog-stereo.monitor 0
Does r3762 fix the problem for you? (untested) If so, please close this ticket.
Note that this only unmutes the source, this won't touch the volume which may be set too low. (but we will not touch that - it would start to get far too messy, far too quickly)
Also, as I mentioned before, your setup will forward all sound from the existing pa server to your client... are you sure this is what you want?
Not heard back, closing. Feel free to re-open the ticket.
