[SOLVED] Audio no longer works after upgrading to KDE4.4

[Guest]

//Solved the audio problems, read the ending of the post.

Hi.

I upgraded to KDE 4.4 on my Kubuntu 9.10 (64bit). The upgrade didn't go so good, I thought, there were some dependency issues that I managed to solve with the -f option. After that, everything was working... for a while. When I started up the computer today I got a box saying
KDE detected that one or more internal sound devices were removed.
Do you want KDE to permanently forget about these devices?
This is the list of devices KDE thinks can be removed:
Capture: HDA Intel (ALC889A Analog)
Output: HDA Intel (ALC889A Analog)

When I go to System Settings -> Multimedia, HDA Intel (ALC889A Analog) is on top of the list (the preferred device) but it is grayed out.

I tryed to playing some media with mplayer and the audio worked fine. There is no audio for programs like Amarok, however.

I tryed inspectin the problem with the help of Ubuntu SoundTroubleshooting Guide:

aplay /usr/share/sounds/alsa/Front_Center.wav
Audio plays fine

fgrep -ie 'audio' /etc/group
audio:29:bubba


sudo aplay -l

I'm a bit worried about the upgrade to kde4.4 I did, I was told that using -f was not such a good idea. It didn't install updates with just apt-get upgrade, however, so thats why I used it. For some time, everything seemed to work fine, until today when I booted up the computer and got the audio problem.
Will I be having problems because of this in the future? 'apt-get check' doesn't give any errors at the moment. I really like KDE4.4 better than KDE4.3.2, it has fixed some issues I had with 4.3.2.


But what about the audio problems? Why did it stop working all of a sudden? It still works for programs like Mplayer, no errors in the log or anything there. But why does KDE report the audio devices as 'removed'?

EDIT:
Audio works again after booting into older kernel (2.6.31-14-generic) and then booting into newer (2.5.31-19). But still, is it a good idea to use this system or will I have problems in future because of the whole upgrade dependency mess?

Re: [SOLVED] Audio no longer works after upgrading to KDE4.4

Actually I had the same problem, and your resolution did not work.

I found the solution, in fact pulseaudio was not redirecting the sound to the correct output.

I have a laptop, Dell Inspiron 6400, and this is what I did :

From the K Menu:
Open the PulseAudio Device Chooser

It open the app in the tray, click on the tray icon and the select "Volume Control"
Goto the tab "Configuration"
Select from the dropdown "Analog Stereo duplex" (in my case, may be something else for your hardware configuration)

Check in the
KDE Systems Settings > Multimedia
that PulseAudio is the prefered output for all apps categories.

That's it.
