Whose bright idea??..

OK I've just installed KDE 3.2 and to my dismay I've found that as it says in the Control Center 'The KDE system takes exclusive control over your audio hardware,blocking programs that may wish to use it directly.'

What this resulted in is my not being able to change the sound level from within say XMMS, Xine ,Mplayer , Audacity etc , etc. In fact Audacity 1.2 pre 3 won't even play properly at all. Now in the beginning if I don't click in some really short value in the little button that says ' Autosuspend if KDE idle after x seconds' then XMMS won't even start playing. wtf???

I don't know how exactly I did it but at one point while a track was playing in XMMS I got full control of the sound volume through it. I don't know if I was supposed to but I would like to do that again somehow. My sound system is Alsa 1.0 , kernel 2.6.1 , original system Suse 9

If you do not intend to use sound with kde applications, you may want to disable the sound system in the control center. But if you wish to keep it, you can try to put "0s" in the auto-suspend field, if I understand well what it is said, it should give up the exclusive control.

It should , shouldn't it? But it doesn't

Yeah I'm having trouble with this too.

[code:1][SDL Init] ALSA lib pcm_hw.c:1055:(snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed: Device or resource busy[/code:1]

I tried the Auto-suspend after 0 seconds fix and even disabled the sound system altogether in the control center but no luck.

Just to confirm this is a kde issue, running the same game (several have this problem but the one I am testing with is frozen-bubble) under fluxbox has no such problems.

Any ideas?

Autosuspend for some reason seems to work only after 1 second or more NOT with 0 seconds. It seems to be solved only by killing the IEC958 output from my card every single time I log in - KMix won't save this setting

same thing here. SuSE 9 Pro with KDE 3.2 with sound blaster card. using a purchased oss driver. in control panel having it auto suspend after 1 second. On starting the RealPlayer you are presented with a warning window claiming that it "Cannot open the audio device. Another application may be using it." Clicking the "OK" button on this warning window and then clicking the "play" button on the RealPlayer - sound comes through. Basicly the same thing happens with xmms.

Using SuSE9.0 and KDE3.2 with SBLive - no problems with sound at all.
Control Centre - sound system enabled, auto-suspend (arts) after 15 secs. Hardware - full duplex enabled.
You will also need to use Kmix (Multimedia/Volume Control). Right click icon and show mixer window. Select soundcard (ie mine comes up with the onboard card and SB) - input/cd level set to max with mute off, then set output/master vol to whatever, which should then play a cd using Kscd or Xmms.
In a console type "artsshell status" which will tell you what arts is doing or use multimedia/administration/aRts Control. View option lets you see status.

Note:
Arts is the KDE sound system. It takes control of dsp...truth, but thats the way it works and its a bit hard to fight against it. Even if you suspend the server you have also so stop all needs for sounds withing kde apps. For example, if some application produces a beep the server will be started again.

XMMS has an arts output plugin. Same for mplayer. This means that they can take advantage of arts. You can have xmms and mplayer working at the same time, for example, without arts you could not.

If an aplication does not support arts then it can be run as
[code:1]artsdsp <application>[/code:1]
