I'm using openSuse 11.3 with KDE 4.5.2 (Amarok 2.3.2) and PulseAudio.

I'm not sure if this is a problem in Amarok, but it only happens when Amarok is playing some music.

If get a message in Kopete, the master volume and the volume of the Amarok stream jumps to the maximum.
It's propably important that incoming messages produce a sound notification and the notification stream is set to maximum.

I'm not the only one with this problem:

I'm not sure if this is related, but it seams strange that changing the master volume also changes the volume of the Amarok stream.

The changing of the Amarok volume with the Master volume is related to Pulseaudio volume leveling support.

See this to disable it: viewtopic.php?f=115&t=90582&p=171966#p171966

Okay, thanks. This solves the problem with the master volume.

But still, if I get a sound notification, the volume of the Amarok stream jumps to maximum, no matter how it is before.

This shouldn't happen, does KMix work with Pulseaudio? If it doesn't, check using pavucontrol. Please ensure the Notifications volume is set to 100%.

KMix works perfect. It shows exactly the same as pavucontrol.

Can you try watching the controls to see what changes are done when a notification occurs?

The control of the Amarok stream volume jumps to maximum in Kmix and pavucontrol. All other controls stay where they are.

I also tried running Kaffeine while I get a sound notification. This stream does not change the volume. Therefore problem must be somewhere in Amarok (and Pulseaudio).

That is definitely not expected.. can you reproduce under a new user? I can't reproduce.

I can't reproduce it with a new user either.

The question now is, which configuration files I have to delete/modify. I definitly don't want to delete all of them.

Try removing the KMix configuration file, ~/.kde4/share/config/kmixrc first.
Make sure KMix is closed.

Also, try removing ~/.pulse/daemon.conf, ~/.pulse/default.pa and ~/.pulse/client.conf if they exist.

I deleted kmixrc and kmixctrlrc and the whole .pulse directory.

After I restarted KDE, Phonon and KMix did no longer find PulseAudio, but I solved this by killing the pulseaudio daemon and restarting it.

Seems to work fine now. I will test a bit more, but thanks a lot! Was a very annoying problem.

I have the same problem, although I'm not using Pulseaudio at all. I use ALSA and mplayer phonon backend. By switching to VLC backend the problem is gone.

Too bad that when listening an AAC stream, mplayer backend produces much better sound quality than VLC backend (VLC backend produces some noise that is sometimes quite annoying (but not as annoying as jumping the volume to maximum on receiving a notification)).

cheers guys, I have been struggling to fix this same issue for a few week:S

if only I had found this sooner. Any idea why this happens because I have a friend with same issue but the above has not fixed it
