Hello,
It seems that the Usb codec PCM2904 can be used as a standard Windows sound card. Do you know if it works with Matlab? (which should work with any Windows sound card) Just using the audiorecorder audioplayer Matlab functions should be ok? (specially for playing and recording at the same time) Or else using the Data acquisition toolbox?
Thanks you for all advice, Emmanuel E.

I don't know anything about the PCM2904, but if it does behave like a standard MS Windows sound card, then playing and recording together is difficult. Syncing the start of the play back with the start of the recording, to within less than 10 ms is extremely difficult. Neither the standard audio-player/recorder nor the data acquisition toolbox will get you anywhere close (never mind the hisses, clicks and pops that audioplayer gives you). If you want synchronous playing and recording with reasonable latency in MS Windows you need an ASIO compliant soundcard (or custom hardware).
