Hello, Every time I boot my VAIO VPCF111FB, the sound starts working ok in KDE. After some time it is running (sometimes hours, sometimes days), audio stops working in KDE. KDE notifications don't produce any sound and KDE applications do not either. However, non-KDE applications like mplayer continue producing sounds normally. The problem is "solved" temporarily with a reboot. Also, when I go to SystemSettings -> Multimedia after the sound stops working, I get a messaging informing that KDE has detected that one or more internal sound devices were removed (?!) and asking if KDE can permanently forget about them. The supposedly removed devices are: Capture: HDA Intel (ALC275 Analog) Output: HDA Intel (ALC275 Analog) Output: HDA Intel (ALC275 Analog) #1
After a reboot, the devices magically hurry back inside the notebook and start working again. Before Natty I was running Lucid in this very computer with no sound issues at all. This happens after a clean Kubuntu 11.04 amd64 install and also happens if I first install Ubuntu 11.04 amd64 and add kubuntu-desktop later. Since Jaunty, I have always installed first Ubuntu and later added kubuntu-desktop, because I used to have similar sound problems when installing Kubuntu directly (with other computers, before I've bought this one) that seam to be solved this way. But now with Natty, the problems persist even if I install Ubuntu first. Any idea of what may be causing this? I hate having to reboot the computer every now and then.
