Configuration to utilize AudioFeedbackLatencyTest( ) correctly

I am very fond of Psychtoolbox. I commend the writers for maintaining this invaluable tool.

The psychtest I am having trouble with is the AudioFeedbackLatencyTest( )

%%% version function AudioFeedbackLatencyTest(roundtrip, trigger, deviceid, nrtrials, freq, freqout, fullduplex, runmode)

I need to test one specific deviceID using AudioFeedbackLatencyTest( ) because it is the one I use in an experiment but any attempt to specify device id results in errors

using any of the following commands (Selection of errors produced: (small exert … denotes lapse))

AudioFeedbackLatencyTest(0, 0.1, 6, [], [], [],[],0)>>>
AudioFeedbackLatencyTest([], 0.1, 6, [], [], [],[],0) >>>
AudioFeedbackLatencyTest([], 0.1, [6 6], [], [], [],[],[]) >>>
AudioFeedbackLatencyTest(1, 0.1, [6 6], [], [], [],[],[]) >>>

*************** command line output **************

Even so, there doesnt appear to be any latency measures returned in the command line output.

Using >>> AudioFeedbackLatencyTest() >>> without any arguments returns basic info from Device info above and does not appear to give any other timing test

Any assistance in this would be greatly appreciated. Details of system below.

My only free remark is that this ptb version is end of life and unsupported since forever. Upgrade to the latest PTB, see if it helps. Other than that, help PsychPaidSupportAndServices for buying 30 minutes of paid support, currently still for the “christmas discount” price of 99 Euros + sales tax. I only skimmed your message very quickly, so i don’t know if 30 minutes would be enough, or you’d need the additional 300 Euros + tax packages, because 30 minutes might already be needed to decipher what you’ve wrote so far. E.g., I don’t understand what is wired to what, ie. your hw setup.

Have a nice weekend,
