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.
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.
I am sure it can be done but my pulse audio-fu is very limited, any help
will gratefully appreciated.
Have a nice day,
