How come QAudio works on 4 of my platforms but not the 5th?

[MattPhillips]

Hello,

So basically QAudioDeviceInfo sees the available devices and I can play audio with QAudioOutput on the following 4 platforms I use:

-Dell Inspiron 640m laptop, Windows XP
-Dell Inspiron 640m laptop (same one), Ubuntu 10.04
-Mac Pro running OS 10.6
-HP elite desktop, Windows 7

But it doesn't see any devices and audio examples won't work on this one:

-HP elite desktop, Ubuntu 10.04 (same machine as HP above).

That is, QAudioDeviceInfo::availableDevices returns an empty QList.

Any ideas? I'd really like it to work on that platform. Thank you--

Matt

I'm having the same issue with a Sager laptop with Ubuntu 10.04. Nobody has any clue? I'm using Qt 4.6.2

Probably because the audio requires proprietary codecs that aren't available under Linux, or at least don't ship with the open source distribution.

Or, it's simply due to the nightmarish chaos that is Linux audio.
