<![CDATA[[solved] QAudioDeviceInfo::availableDevices - no device found, if start on PC without Qt installed]]>Hi, all...

Qt 5.3.2 (mingw482_32)

This sample code :
...
foreach (const QAudioDeviceInfo &deviceInfo, QAudioDeviceInfo::availableDevices(QAudio::AudioOutput))
{
ui->terminal->append ( "Device name: " + deviceInfo.deviceName());
}
...

works fine if start on PC where Qt installed. If I start .exe on PC without Qt, QAudioDeviceInfo::availableDevices return 0 audio output device.

My PC (with Qt) is Windows 7 (64), other PC is Windows XP, 7 (32 bit)

You're welcome !

Since you have it working now, please update the thread title prepending [solved] so other forum users may know a solution has been found :)

I tried to act by analogy with Qt 5.0.2

My App folder contains the following files:

@
.\platforms
MyApp.exe
D3DCompiler_43.dll
icudt52.dll
icuin52.dll
icuuc52.dll
libgcc_s_dw2-1.dll
libstdc++-6.dll
libwinpthread-1.dll
qt5core.dll
qt5gui.dll
qt5multimedia.dll
qt5network.dll
qt5serialport.dll
qt5widgets.dll
@

Application to be started, but there are problems described above.

After that I copy Qt5.3.2\Tools\QtCreator\bin\qt.conf file App folder
@
[Paths]
Libraries=../lib/qtcreator
Plugins=plugins
Imports=imports
Qml2Imports=qml
@

and copy Qt5.3.2\5.3\mingw482_32\plugins folder to App folder :

@
.\plugins
..\audio
..\platforms
MyApp.exe
D3DCompiler_43.dll
icudt52.dll
icuin52.dll
icuuc52.dll
libgcc_s_dw2-1.dll
libstdc++-6.dll
libwinpthread-1.dll
qt5core.dll
qt5gui.dll
qt5multimedia.dll
qt5network.dll
qt5serialport.dll
qt5widgets.dll
qt.conf
@

... and then everything was fine

Thanks!

Are you sure you deployed your application correctly with all dlls and plugins needed ?
