Note : I'm not sure who I should report this to. It occurs
in Ubuntu Karmic, until you apply, it seems, the alsa
backports modules, then it seems to work perfectly.
With an ASRock P43DE (Intel P43 Express) mainboard, Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller. By default : only one app can play audio, which shouldn't happen because dmix is supposed to be enabled for all analog devices. Of course, if you stick to pulseaudio apps, everthing is fine. When whenever you try to mix pulse / alsa apps, sound is interrupted. I fixed this by adding an /etc/asound.conf file (attached). With this, dmix is enabled : I can play as many alsa apps I want, with no problem. In KDE, I choose a new "ALSA dmix" entry added thanks to the aforementioned file and choose a gstreamer backend. HOWEVER : - if I use another Phonon backend - if I use Wine or Skype (32 bits apps through AUR, by distro being 64 bits) -> the sound is interrupted. And all the subsequent apps I launch cannot play any sound at all anymore. I only hear the KDE logout sound (?!). -> I have to reboot I do not have those issues in Ubuntu with all the upgrades / backport modules. FYI, here are the other devices listes by the KDE multimedia panel : HDA intel (VT1708S Analog) HDA intel (VT1708S Digital) default hw:0,0 hw:0,1 When the ALSA dmix entry ceases to work, hw:0,0 and the analog output still do... |

I had the same problem, same audio device on a ASUS Mainboard P5P43TD, Kernel 2.6.36 and KDE 4.5.5
I had installed pulseaudio, so I uninstalled it and the problem was fixed.
Furthermore, the system did not recognize my audio device additionally to the mentioned problems at the first post
Tomorrow I will post a comment.
I installed pulseaudio again.
But now I see something different, KMix does not show all channels of sounds, but alsamixer does it (it shows Master, Headphon, PCM, Front, etc.)
KMix only shows a channel, called Analogic audio stereo (it does not appears in alsamixer).
Here a screenshot displaying alsamixer:

Also, when I am listening any sound with JuK I can't listen the sound of videos (flv) in Firefox or Konqueror. But if I close JuK and refresh the web page where the video is embebed I can listen its sound.
I have installed pulseaudio 0.9.22-2, alsa-lib 1.0.24.1-1, alsa-utils 1.0.24.2-1 and kernel 2.6.37
I can solve this trouble by uninstalling pulseaudio, but I guess it not fixes the bug.
Thanks a lot.
