[anonymous]

Follow-up Comment #4, bug #63899 (project octave):

Hello, 
Here is a minimal example followed by the error report:

##### EXAMPLE ######
clear;
close all;
sca;
InitializePsychSound(1);
nrchannels = 2;
freq = 48000;
beepLengthSecs = 1;
startCue = 0;
waitForDeviceStart = 1;
pahandle = PsychPortAudio('Open', [], 1, 1, freq, nrchannels);
PsychPortAudio('Volume', pahandle, 0.5);
myBeep = MakeBeep(500, beepLengthSecs, freq);
PsychPortAudio('FillBuffer', pahandle, [myBeep; myBeep]);
PsychPortAudio('Start', pahandle, repetitions, startCue, waitForDeviceStart);
PsychPortAudio('Stop', pahandle, 1, 1);
PsychPortAudio('Close', pahandle);
##### END OF EXAMPLE #####

#### END OF ERROR REPORT ####

Additional notes: 
- OS: Ubuntu 22.04 jammy,  Kernel: x86_64 Linux 5.19.0-35-generic
- Psychtoolbox-3 for GNU/Linux X11, under GNU/Octave 64-Bit (Version 3.0.19 -
Build date: Feb 24 2023).
- after running the example, there in not sound from the speakers and it comes
back after exiting OCTAVE. 
- this error appeared suddenly without me changing something in the scripts 

I think I will uninstall & re-install Psychtoolbox & OCTAVE. 

Thank you for your time.
