Andy,
By default, for digital RX/TX, you don't strictly need to hear the sound. When
you pushed on I/Q interface "Direct via the sound card", you could RX/TX just
selecting the desired signal on the waterfall. Now if you want to hear the
received sound (the base band demodulated one, not the SdR one), push on
"+Speaker" and select the Auxiliary Sound card (to Speaker)".
You need a second sound card for this:
* a SWL could use the same sound card to RX SdR and listen to the demodulated
sound,
* as a Ham, you must use a first (good) sound card to RX/TX and a second one
(standard) to listen to the demodulated sound.

I'm sorry I don't understand Patrick. How do you "start" the SDR's reception
in Multipsk ? The SDR I have is not playing audio until usual SDR software
starts the receiver and audio flows . I do not see that in Multipsk ?

Multipsk works alone on SdR (RX/TX). You don't need another SdR (and surely
it would be a mess to work with two SdR programs doing the same thing).
Simply, indicate in Multipsk which sound card (or sound cards if a speaker
is added) to work. That's all.
