Bug Description

Binary package hint: amarok

Some weeks ago everything was working fine. Now I have some serious problems with sound. There are 2 different scenarios:

1) I select 'pulseaudio' as phonon back-end
    - Amarok works fine, NEVER stops playing and amarok audio works flawlessly...
    - Only a side effect: EVERY system sound (beeps, flash, other player) can't play any more, is just muted. Pulseaudio (I don't use it in my system, I have manually installed and configured ALSA) steals audio to the whole system

2) I select 'hda Intel (ALC889 Analog) as phonon back-end
    - Amarok works integrated to the whole system sounds (no conflicts) but...
    - After I push play/stop 3 or 4 times or when a new song begins... An error message appears (notification) saying the hda Intel (ALC889 Analog) back-end does not work anymore and it must use pulseaudio...
    - THEN amarok is muted, I have to quit (killall amarok, since its process stays alive) and run again, falling back to problem 1)

Please note until some week ago everything was working fine!!! I think I was always using HDA Analog backend and no problem occurred before... Recently I have updated alsa to 1.0.20, but also all the other packages have been updated... I have *NO CLUE*.

I've filed another bug about a similar case. Later I've found out that Amarok has something to do with this. Amarok works always, but it is the one that breaks the sound from other applications.

Nonsense, Amarok doesn't handle sound itself, it let's phonon do so. Please, do not emit wild guesses about responsabilities, this is at most a phonon problem.

Please, do not file sound issues against Amarok 2.x, it doesn't handle sound itself, but let's phonon do so. This has already been filed against phonon AFAICS.

Changed in amarok (Ubuntu):
status: New → Invalid

And it is not related to a certain hardware it seems. I got this in another computer with Asus AMD board's integrated sound.
