SoundEffect change source

Uwe Koehler

Hi there,

when I change the source of a SoundEffect I hear the old and the new sound with the next play(). Is there any way I can avoid that?

Many thanks for any help in advance

Hi,

Do you mean you only here it once and then it's gone ?

Uwe Koehler

@SGaist Thanks for the reply. Let me clear this up:

SoundEffect {
        id: trialgong
        source: tone
        onSourceChanged: {
            play()
        }
    }

When I now set a new source to trialgong with
trialgong.source = something
I can here the old and the new sound. I would expect to just here the new sound. I am using Qt 5.5 on Linux.

I had the same behavior when issuing

trialgong.source = something
trialgong.play()

instead of using onSourceChanged.

Any ideas?

Hmm, got the same problem when using QSoundEffect in C++. I am preparing a small sample project for a bug report. Have to learn how to record the output in Linux to attach.

Tried on Android and cannot reproduce the problem there.

If it makes things simpler, use an external device like your phone to record the output

Many thanks for your encouragement.

I filed bug report QTBUG-48982 including a recorded sample output and an example project.

Thanks !

Since 5.5.1 is out, can you test with that version to see if it behaves better ?

Still happens with Qt 5.5.1 Linux. Added Comment to the bug report to that respect.
