Dear All,

openSUSE 11.2, KDE 4.4.4

If I use amarok to change the volume or receive a notification from kopete: the volume of the PCM channel jumps to maximum.

I don't want this feature or bug because the sound quality gets very very bad if PCM is maxed out. Would love to keeps this around 90 %.

This issue is probably a known issue but I was unable to find correct keywords to google for.


Anyone else with the same issue?

I can't reproduce this here, using Amarok 2.3.1-git with KDE 4.5.0 on Kubuntu 10.04, no pulseaudio. Do you use pulseaudio?

I was not. I turned it on in Yast, but the issue is the same.

The question about pulseaudio was only to know what are your settings, I did not ask you to install it...

Did you try setting your master channel to master instead of PCM? This of course depends on your sound card, but here, using a laptop with an internal Intel sound card this is the default setting and I have no problems with that.

Setting the default to master was the first thing I did.

Seems to be that pulse was installed on this Laptop already: I did not add any packages, just turned it on.

Shall I remove something?

Well, if you use Pulseaudio, you should not use KMix, but pavucontrol to control the volume, did you try that?

pavucontrol was not installed so I did it.

Pulse Volume Control did not have a pot-meter to set this PCM.

Issues are still the same with Amarok:
- if I hit the "next song"
- use volume control of Amarok
- quit Amarok

the PCM jumps to maximum.

That is most bizarre... I need to ask a developer, I have never seen that behavior, and never heard about that before neither.

Thank You.

It would be actually a nice feature. But I would like to set it to jump up to 90% instead of 100%.

There's absolutely no way that Amarok could influence the PCM volume by itself (its volume effect is purely software based).

Apparently this is related to pulseaudio:

I have red this manual. What shall I do now?

I am a beginner... But my doubt is that does not mater if I turn Pulse of or On, the issue is the same. Is this fore sure pulse related? KDE has nothing to do with it?

I am sorry for this. Maybe this is the wrong forum but when I opened this thread: this "flash based" helper gave me this only best choice.

Well, I doubt it is KDE related, I have never heard of that before.
Also, it is hardly Amarok related, as Amarok doesn't handle sound itself, but lets Phonon do so.
I will get a Pulseaudio specialist to have more information and see if he can suggest a solution.

I am using my desktop PC now. (I am back to town after a week holiday )

Here I have opensuse 11.3 and KDE 4.4.4 and experience something interesting.

Here if I adjust the volume using the pot-meter in Amarok, I am experiencing something really cool:


volume UP: PCM jumps to 80 %, master starts go up slowly. When master reaches the maximum, PCM goes up as well.

volume Down: PCM jumps down to a certain percent (aprox 15 %), Master moves slowly and when reaches the bottom, PCM starts to move to zero as well.
