Phonon and Silent Profile

[Sasler]

Is there a way to play audio files using Phonon while the device is in Silent profile? I'm using the default 4.5 Qt.

Thanks

I think it violates the purpose of having Silent profile.

Well the media player works fine in silent profile. Also the alarm clock does. I think it should be possible.

[Sasler]

Does anyone know a solution for this? It should be possible, no?

OK, I found a hack in this page involving editing xpolicy.conf.

It works, but it's a rather dirty hack. There must be a better way to do this.

You should use libplayback for that as proposed by Stefan.

I have no idea how I can do that? Are there some examples of using it in Qt?

[divanov]

No, there is no example using Qt.

Hi,
Phonon generally can be classified as broken at best.

I would just use the S60 Sound Mixer example 2.1. I did that, and now have lower latency and a generally better user experience...

[divanov]

Do you believe S60 example will work on Maemo?

[tamhanna]

Hi,
oops - my bad. But there must also be a native Maemo example!

[divanov]

Phonon is abstraction layer to hide platform specific implementation from Qt applications. On Maemo Phonon falls back to Gstreamer. There are Qt examples using Phonon and Gtk examples using Gstreamer. One can use Gstreamer directly from Qt application, however, it's not going to solve any problem as there is policy in effect. In order to override the policy one needs to use libplayback to tell daemon that your application is media player and it requires playback resources. On the other side at the moment only libplayback-1-dev is available, no examples and no online documentation.
