If so, what does the custom audio config look like, including the ecasound command?May be wrong, but IIRC, it just needs to define a second output and enable both. And both will be played automatically.
There are other ways to do this, via JACK (low latency), via pulseaudio (poor sound quality IMO), but the two outputs is probably the easiest. I havn't tried this yet, but if you have two audio devices, try adding them both in the config and see if it works. If not, I'll add in some extra logic ot make that happen, and will see how it goes from there.
