system sound problem

[Husse]

This is the dreaded Intel 82801....
Try this

Code: Select all

gksudo gedit etc/modprobe.d/alsa-base

with KDE

Code: Select all

kdesu kate etc/modprobe.d/alsa-base

add this at the end of the file

Code: Select all

options snd-hda-intel model=auto

You can try to change auto to something like HP
Reboot - or reload sound, but I honestly don't know the command
Edited to correct a nasty error - and it should be /etc not etc - but this is kept so the rest of the topic is understandable //husse

I am sorry - I copied the text without noticing that /alsa-base was missing at the end
I have corrected this in the post - try again
(modprobe.d is a folder....)

[Husse]

OK
first in a terminal

Code: Select all

gksudo gedit etc/modprobe.d/alsa-base

This file may or may not exist in your system
then paste

Code: Select all

options snd-hda-intel model=auto

Save
Done

[Husse]

just the matter of one little / makes a difference

I really have to apologize - this was copied from an earlier post and I wrongly assumed it to be correct
Put it at the very end
Of course I should see this kind of errors but.....
(And the original post was not by me I think Even more important to check )
