Another newbie's sound problems

[CrystalWitch]

I am brand new to Kubuntu (and Linux). I have an ACER Aspire 5051 and when I was testing with the live CD of 7.04 at first I couldn't get sound, but after a bit of playing with Kmix, everything seemed to be OK, so I did the install,and again everything seemed OK. A couple of days ago there were a whole load of updates, so I installed them.

Since then, Kmix has changed - things like the surround slider (that solved the original problem) are gone, and I've had a problem with sound. I can't hear anything from the speakers. If I plug speakers into the headphone jack, I get no sound on the left channel, and very quiet sound on the right channel. If I use headphones, there is a little sound on the left, and more on the right.

I don't know enough yet to do much. Can anyone help? I've read a lot of sound problems on forums, most are for ubuntu not kubuntu, but I've seen requests for output from a couple of commands, so...

If you can help, it really needs to be at absolute novice level... I'm trying to get this installation to work so I can start learning something that isn't windows!

Thank you

Alt+F2:

kdesu kate /etc/modprobe.d/options

add:

options snd-hda-intel model=3stack-6ch

and reboot, if it won't work, then remove the option

Re: Another newbie's sound problems

Thanks for the suggestion, but it didn't seem to change things,

Suzie

what if you add the same option

options snd-hda-intel model=3stack-6ch-dig

to

/etc/modprobe.d/alsa-base

as explained here

Solved - Re: Another newbie's sound problems

Thanks for that. I found a script on http://www.stchman.com/ a little while ago that seems to have worked.

Re: Another newbie's sound problems

Thanks for posting the link to that script CrystalWitch!

I did have very quiet sound on my system and none of the posts i searched through (many of them!) had a solution that worked. The script from the link you posted work like a charm and all aspects of my sound are working properly again

Re: Another newbie's sound problems

Didn't for me. Oh well. Was worth a shot.

For me, I still have to add acpi=off to the kernel line in /boot/grub/menu.lst in order to have working sound.

Re: Another newbie's sound problems

Glad it works for some, if not everyone. What is interesting is that I decided to rebuild my machine from a Kubuntu Gutsy live disk, and the sound worked without using the fix... SO that might be worth trying too,
