Copied here:

In GlassGui Audio Sources, When the Type is AudioScience HPI, in addition to:

[example]

ASI6622[1] - Input Stream 1 ASI6622[1] - Input Stream 2

With Input Source: options:

Line In 1 Line In 2 Output Stream 1 Output Stream 3 Output Stream 3 Output Stream 4

Add:

ASI6622[1] - Output Stream 1 ASI6622[1] - Output Stream 2

With Input Source: options:

Line Out 1 Line Out 2

etc. as needed.

BTW, I tried using the combo:

Input Stream 1 Output Stream 1

which works but only when rdairplay is using that particular output stream and so you get music and silenced intermixed via icecast...

all the best,

Yes, and that is precisely the rub. For ASI cards, each audio play-out in Rivendell gets its own output stream context, with the particular stream used being selected more-or-less randomly. Thus, any output stream chosen as the GlassCoder input will, at best, only provide 50% of the desired audio play-outs from Rivendell.

So, IIUC, even though they all come out of the same physical "wires"... there is no place before the wires that you can "tap" in software?
