[kde] Re: No sound in Kubuntu 11.04
I found that sound improved after I installed VLC and even the kmail sound notification still worked. I accepted a kde base lib update the other day. For some reason it set up hdmi on my graphics card as the default yet again and switched phonon's back end to xine and pushed the vlc one to the bottom of the preference list. Gstreamer is in the middle. Initial impression of the xine back end is that sound is good. ;-) Need to receive more emails to get an idea. I use an old sound blaster echoing thunder sound file. There may be a problem though. Kmail defaults to gstreamer and I wonder if applications pick from the available phonon backends to suit themselves and phonon accepts input from any of them. Installing vlc may have caused it to hook up to all sound sources and the update may have changed that.. You may do better to ask on the Kubuntu forum about this. It's odd really as I did try Kubuntu and it's official installs looked to be ok. Didn't load VLC though. What put me off was the fact that I couldn't find a way of using the root account. John Opensuse 11.4 KDE 4.6.0 - 6. (VLC 1.1.9 packman build for opensuse) As an aside I altered vlc.desktop such that it notifies kde when it's starts up just like kde apps do. The cone no longer bounces about for long after the app has started. - Original Message From: Duncan 1i5t5.dun...@cox.net To: kde@mail.kde.org Sent: Mon, 30 May, 2011 7:09:55 Subject: [kde] Re: No sound in Kubuntu 11.04 Marcelo Magno T.

After a few days I'll post the results (got to give some time to be sure sound will not fail again, sometimes it lasts for a few days before failing). Do try it, but FWIW, I have a bit of new information. Upon updating my Gentoo installation yesterday, there was a change in phonon's default USE flags, switching the default backend to phonon- gstreamer from I believe phonon-vlc. Needless to say I kept the vlc backend as I don't even have gstreamer installed and don't want it installed. (In Gentoo, such options are controlled by USE flags set at the time the package is built, normally by the user since Gentoo is a scripted- from-source distribution, so keeping vlc simply meant overriding the USE flag defaults by setting the ones I wanted.) But the important bit, the new information, is that according to the gentoo package scripts changelog, from phonon 4.5.0, upstream kde is defaulting to the phonon-gstreamer backend. As I said in my original reply, that blog I read was about a year ago. It's possible they now favor the gstreamer backend now, thus making it the default, or it may simply be bowing to the the fact that so many distributions default to gnome and thus to gstreamer already. I don't know. But, what I DO know for sure is my own experience, that the phonon-xine backend kept giving me messages about disappearing devices even tho it's the device on the mobo, and no, I did NOT change the BIOS to disable it, and that all those problems disappeared when I switched to phonon-vlc. As I said I've never tried the phonon-gstreamer backend, and wasn't even aware that it had the disappearing devices problem too, but with luck, switching to phonon-vlc will cure the issue for you as well. Please do follow up when you're sure whether it's cured the problem or not, as I really am curious, especially now that I know you're using gstreamer AND know it's the kde default now. As I said, I wasn't aware that the gstreamer backend had the problem too -- maybe it's just luck that the vlc backend works so much better for me? The other possibility of course is that it's version-dependent. Maybe phonon-gstreamer only matured with phonon 4.5, and perhaps you're running an earlier version? But in any case it's worth giving the phonon-vlc backend a try, since it did cure the problems I was having. If it doesn't work any better, you can always try something else. -- Duncan - List replies preferred. No HTML msgs.
