Hello, 
The audio part on Psychtoolbox scripts has suddenly stopped working.
I tried:
1. old scripts of mine that were working 100%
2. a Psychtoolbox tutorial that I found here:
https://peterscarfe.com/insertedCode/beepDemoCode.html
3. the command PsychPortAudioTimingTest

I always get the same error (here below is the result from
PsychPortAudioTimingTest):
###
PTB-ERROR: Desired audio parameters for device -1 unsupported by audio device:
Illegal combination of I/O devices
PTB-ERROR: This could be, e.g., due to an unsupported combination of audio
sample rate, audio channel count/allocation, or audio sample format.
PTB-ERROR: On Linux you may be able to use ALSA audio converter plugins to
make this work.
Error in function Open:         Usage error
Failed to open PortAudio audio device due to unsupported combination of audio
parameters.
error: PsychPortAudio: Usage:

pahandle = PsychPortAudio('Open' [, deviceid][, mode][, reqlatencyclass][,
freq][, channels][, buffersize][, suggestedLatency][, selectchannels][,
specialFlags=0]);
error: called from
    PsychPortAudioTimingTest at line 161 column 10
###

I have attached a screenshot with the errors. 
Thank you in advance for your time, 
Vera
