Sound won't work

Asked by CottonRLS

This is the first time I've installed Kubuntu, and I'm very surprised I can't get the sound to work. I've worked with Mandriva before, and never had to massage any sound settings to get it to work, but I've gone into the Sound System|System Settings screen to check what's being loaded. I've tried every choice available under the Hardware tab, starting with Autodetect all the way through ALSA, OSS, etc. and not one gets so much as a peep out of the Realtek audio on the motherboard.

I get nothing from the Test Sound button, and Amarok gives me the message that xine was unable to load any audio drivers.

Any ideas?

You should install gstreamer audio decoders for the ubuntu variants to play Mp3 or any other audio formates other that free audio formates like Ogg.

Just install required audio codecs like

1) All Gstreamer extras in adept-package manager.

2) install win32 codecs

3) install ffmpeg and some other audio codes to play all audio and videos

The system continues with no sound at all. Same error messages, too.

It appears that this audio chipset has been problematic in the past.

I have one guess that might work:

Add the following line:

options snd-hda-intel model=3stack

tp '/etc/modprobe.d/alsa-base'. I.e. run

gksu gedit /etc/modprobe.d/alsa-base

paste the line, save and quit.

I added the line saved and restarted. I saw a small window appear on the desktop for a few seconds that referred to ALSA, but it disappeared after a couple of seconds. I remain without sound, however.

There was evidently something in the KMix applet that was checked or not checked by mistake at install. If anyone else has this problem, it might have been the preceding tip plus fiddling with KMix that did it, but thank goodness it is finally working.

Thanks everyone,

Cotton
