Re: run more pair of loudspeakers at the same time
Why do you speak about multiple "sound cards " instead of multiple "speakers " ???

Because your USB speakers likely contain a separate sound card, so what you really want to do is output the signal over both sound cards (on board/wherever your analog jacks are, and USB).

Oh, that's sound new to me... Does every speaker connected via USB have an integrated sound card ?

Re: run more pair of loudspeakers at the same time
Ah, ok, today I learn something new!
If I use RCA jack instead USB to connect 2.1 speakers , hence one sound card, how can I solve?
