I've just tried this with our own 2-input card, and it's behaving correctly with DirectSoundCapture, ie. whichever input I set the default capture endpoint to, DirectSoundCapture uses that input when I set the pcGuidDevice pointer to NULL or &DSDEVID_DefaultCapture.
Let me know if there's any other tests you'd like me to try for comparison. Jeff----- Original Message ----- From: KS

When I use it on my audio card that expose 2 independent recording endpoint (rec-endpoint-a and rec-endpoint-b), and the default recording endpoint was set to rec-endpoint-a, my directsound application end up opening a recording stream on rec-endpoint-b instead.
When I used RMAA to run a loopback test through directsound on the audio card, I've also found that in order to get the loopback test to use rec-endpoint-b, as I've selected in the application, I have to make sure that rec-endpoint-a is selected as the default in the sound control panel.
Does anyone knows whether this is an expected behaviour, or is it an error in the directsound layer? Thanks.
