kde have problems with sound

Hello :slight_smile:

I have a curious problem. Only recently, on my 11.3 install, kde at login complain he can’t anymore found my sound card.

That said, the card works. The only problem I have is often the sound becoming bad (distorded) when using windows as virtualbox guest (I try to update my driving knowledge with a cd).

This problem I noticed after having tricked the sound to have working the input connector. I did nothing special, only add all the cursors to the mixer and try muting one or th other. Now the mike works.

I have two soundcards, one intel and one nvidia (looks to be only for hdmi output). Any configured by yast without problem.

any idea?
thanbks

What version of KDE are you running?

Send us a picture of sound cards from yast.

kde 4.4.4, stock 11.3 (updated)

curious: the two cards seems to use the same driver (if I highlight the nvidia card, in yast, the card number change, but the driver is the same)

If you go to KDE Configure Desktop -> Multimedia -> Phonon -> Backend what is the item at the top of that list?

I have nothing like “phonon” in the multimedia screen (nor find it in search). I created a new user, with english langage for the sake of simplicity. It experiment the same kde problem

here the multimedia entry

Go to start menu–>system settings–>Multimidia–>Phonon.

start menu–>system settings–>Multimidia

gives the image I posted… no phonon

the only phono part I see it’s in advanced, xine. Yast say I have installed libphonon4, phonon, phonon-backend-xine (I’m in 64 bits intel). I have in yast, not installed, phonon-backend-gstreamer and -vlc

upgrade? do you mean from the hardware vendor? the firmware or the linux driver?

anyway it’s not the hdmi out that have problems (I don’t use it.

I mean that you must choose your sound card HDA nvidia(…Digital audio output and choose prefer according to this icon

well… I just started Windows 7 on this computer and windows don’t see any intel soundcard but an nvidia and an realtek one. that said I don’t find any precise description (I’m much less at ease with W7 than openSUSE :-()

Hi jdd,

I think what stamostolias said is that you have to give first preference for your card named HDA intel analog. Set as the topmost one. Set it for all profiles there. Are you using ALSA or Pulse Audio ? It the problem persist, try installing Pulse Audio.

Right!!!

of course it’s the intel one, the other don’t have any output (other than hdmi). I tried to clic “install” pulseaudio in yast with no visible chnage (but may be it needs login again?)

may be this can be of some use (tooltip on analog device) - when using “test”, there is a normal sound.

Where can I find the content of the error message (displayed by some plasmoid at login time)?
thanks for your help

Now you have sound ok??
Test it with amarok, play a sound file and send results.

the sound was always nearly ok (some problems with virtualbox), but I wonder why this happenned suddenly. sometime, at login, the kde control centrer shows the sound drivers ok, some time not (greyed). It always complain at login but usually works…

Go to start menu–>system settings–>multimedia–>phonon and prefer nvidia HDMI(HDMI audio output)

And reboot.

notice I still have no “phonon” menu entry, the list is right from the multimedia entry (probably don’t matter).

I did what you asked for: set nvidia at the first line (using “up”). Using the button “test”, no sound
reboot. Test still don’t give sound, but video plays nicely with sound (probably from intel) - always the same login message “intel don’t works”. May be it’s only a time problem (some test too early? the card is slow to answer - it’s an i5 computer, pretty fast)
