I would guess that you're loading module-tunnel-sink without the "sink" parameter, so it will connect to the default sink of the remote server, in this case the alsa sink. Pass "sink=NAME" to module-tunnel-sink when you load it. Replace NAME with the name of the jack sink. -- Tanu https://www.patreon.com/tanuk
