Hi everyone,
does anyone can help me, please, with a problem I often have with the real-time audio output in csound (using csoundqt frontend)? I know it might probably be a very stupid and simple task to solve, but it gets me crazy all the time, because  I can't understand the reason why it doesn't work. After installing the software on windows machine (with the installer), when I run the instr (without errors in the code) I can't hear any sound. Audio setting are ok by defaults (I never change settings on realtime window task leaving them set by default), but even if I change, setting them with the soundcard installed on the computer, it doesn't work. Sound card is ok because I can use it without any problem on others audio application (Audio editing or just a simple player). This is the message I get all the times (without hearing any sound and the button "run" seems not to compile the code):

0dBFS level = 32768.0
orch now loaded
audio buffered in 4096 sample-frame blocks
PortAudio V19.5.0-devel, revision unknown
Failed to initialise real time audio input

I'm trying it with very simple lines of code just for testing:

instr 1

asig poscil .5, 440
outs asig, asig
endin

;score
i1 0 4

Thank you in advance
Salvatore

Could and invalid input device (-iadc in CsOptions or portaudio in
CsoundQt's settings) be the cause?
