PsychPortAudio: How to know the content of a filled buffer?

1
Dear all:

I've developed an .m file for playing 2 multichannel audio files in a pseudo random order.
I'm using a pamaster handle, and 2 slaves pahandles: paNS and paDS.
Then I directly fill their buffers with their corresponding audio data.
the problem is that when y start the software, no audio comes out and the playing time is too short.
All makes me suppose that both buffers (paNS and paDS buffers) are empty.

Here maybe you can help me:
How can I check if the buffers are really filled?
can I display the data on the buffers after they are filled?

Every opinion will be very welcome.

THank in advance,

Alejandro Bidondo.

Look at BasicSoundScheduleDemo on how to define "playlists" of sounds, repeatedly played in various order. That is the most efficient way to do this.

Other than that, your post doesn't contain any useful information, e.g., your playback code, info about os and hardware used, output of ptb into the command window, how our own demos behave, what you've tried to fix it yourself.

Another gently reminder about how to use this forum:
