Unable to play a wav file with Audio component

zyend

Yes, it is always the same.

I have also edited the qalsaaudiooutput.cpp and added some fprintf() statements and nothing is displayed in the console.
I put a message in open() and in the constructor

However, it prints loaded library "/usr/lib/qt5/plugins/audio/libqtaudio_alsa.so"

I don't know what I can do to figure out what's happening.

SGaist

Did you install the plugin properly after having built it ?

zyend

What do you mean "install properly" ?

SGaist

Are you sure that the plugin you modified was installed at the right location ?

zyend

Yes.

It was installed under /usr/lib/qt5/plugins/audio

SGaist

On your target ?

zyend

Yes, of course.

SGaist

How big is your audio file ?

zyend

~11 MB.

Would you test it ?

I have recompiled QtMultimedia without ALSA support and with PULSEAUDIO only.

In /usr/lib/qt5/plugins/audio I have only libqtmedia_pulse.so

Same thing when I launch my app again. libqtmedia_pulse.so plugin is loaded , and I have the same output as the one above...

It really seems that something is wrecked under...

SGaist

I likely would (and already would have done it) but I don't have such a board at hand.

And Rulseaudio is also working correctly ? (Without using Qt)

zyend

How can I test if pulseaudio is working fine ?

SGaist

I'd take a look at thist to check the setup.

@zyend - I know the topic is quite old, but could it be a simple explanation of a typo ?
You have called the Audio component:
id: audioPlayer
and then try to play with:
idPlayer.play()
I think it should be:
audioPlayer.play()

Maybe I am reading the post wrong.

@zyend
Although this is an old post, I ended up here Googling for the pulse audio initialization and someone else might do so too so here's important info for the solution of the problem.
I too ran into issue that pulseaudio was no longer running since the

QAudioDeviceInfo::availableDevices(QAudio::AudioOutput)

had been dropped from the code. This call apparently starts pulseaudio daemon (among other things).
Returning it back fixed the issue.
