The author of the dlna plugin has told me that the combined sink feature
is not implemented in his module. He has given me an alternative with
the loopback module:
load-module module-loopback sink=alsa_output.pci-0000_00_1b.0.analog-stereo
Then pickup the loopback on the Chromecast. It works but, as expected,
it is not in sync.
So the source of the loopback is the monitor source of the chromecast sink?
I am now looking for a way to delay the local playback but I can't
figure out how.
I tried latency_msec=3000 but it set's the latency on the Chromecast.
If the source of the loopback is the monitor source of the chromecast
sink, increasing the latency of the loopback module should increase the
latency of what is played to the alsa sink, not the chromecast sink.
It's a known problem that something is wrong in module-loopback related
to the latency_msec paramter:
https://bugs.freedesktop.org/show_bug.cgi?id=80770
The loopback patches that Georg Chini submitted recently probably fix
the latency_msec parameter behaviour.
The bug Tanu is referring to should already have been fixed with
pulseaudio 10.0, although with the loopback module of 10.0 it will
take quite a while until it has adjusted to the correct latency.
You can check the latency of module-loopback if you enable debug
logging.

Georg
