Error on uos_AddIntoDevOut

[LemonParty]

Hello, again.
I trying to play mp3 file.
I successfuly called uos_CreatePlayer and uos_AddFromFile then I called uos_AddIntoDevOut and get error SIGSEGV on line #6750 "err := Pa_GetDefaultOutputDevice ();" in unit uos.
What it could be?

Hello.

Did you try the demo simpleplayer.lpi in /uos/examples/ ?

Is it working?

[LemonParty]

It working.

If simpleplayer demo is working, then maybe something is not ok in your code.
Did you load portaudio?

Can you show the code you used?

This is how I load library:
  Result:= uos_loadlib(nil, nil, PChar(ProgramsDir + 'dynlibs\Windows\64bit\LibMpg123-64.dll'), nil, nil, nil) = 0;
Result is true, I checked.

And this is how I load files. Checks not present, but I checked with debugger that first two functions work fine. FPlayerIndexes[i] = 1 in this case:
  uos_CreatePlayer(FPlayerIndexes[i]);
  InputIndex:= uos_AddFromFile(FPlayerIndexes[i], PChar(FTimerFrames[i].Sound), -1, -1, -1);
  {$if Defined(CPUARM) or Defined(CPUAARCH64)}
  // need a lower latency
  OutputIndex:= uos_AddIntoDevOut(FPlayerIndexes[i], -1, 0.3, -1, -1, -1, -1, -1) ;
  {$Else}
  OutputIndex:= uos_AddIntoDevOut(FPlayerIndexes[i], -1, -1, -1, -1, -1, -1, -1); {at this line occurs an error}
  {$EndIf}

OK, this one is the problem.  The result is true but you did not load portaudio, who is the first parameter and is needed to access your sound card(s).

Try with this:

  Result:= uos_loadlib(PChar(ProgramsDir + 'dynlibs\Windows\64bit\LibPortaudio-64.dll'), nil, PChar(ProgramsDir + 'dynlibs\Windows\64bit\LibMpg123-64.dll'), nil, nil, nil) = 0;

Yes! It solved an error. Music plays.
Thank you.
