hi Joao,

I'm sorry, but I didn't understood. Can you give me an example of the command line?

oops, after spotting SuSE mentioned somewhere in your post, I must have been under false impression that your main platform is linux. But perhaps there is a bash equivalent on Windows (cygnus?).

What I meant was if I could test the input into the program from an internal source (like cd or wave out from media player). The question was how to connect both ends.

oops again. I was misled, because you inquired for a patch to test the connection, and _not_ about how to setup such a connection. Anyway, if I understand this question correctly this time, it is mostly about how to setup audio in Windows in general, and not in Pd. On a Pd side, you may need to use -soundindev/-soundoutdev options, that is all.

Or, providing your soundcard is full-duplex capable, have you ever tried using a hardware loop (but be careful), and running two Pd sessions simultaneously, one with -noadc, while the other with -nodac? Of course this could be useful for external connection testing only, but for any other testing purpose just replace [adc~] with any signal source internal to Pd.
