[Solved] Linux Mint on Acer Extensa 5220 laptop no sound capture.

[RytronII]

Hi,
I am unable to capture sound in sound recorder or GTK RecordMyDesktop.
Does anyone have a solution?
I use Linux Mint Elyssa.
Thanks.

You make the common (and easy to understand) mistake to believe that telling us which laptop you have tells something about hardware - it tells it's an Acer....
Unfortunately lots of laptops can have widely different components and have the same name
Run lspci and post the result
And which edition of Elyssa?
Finally - sound capture - what about sound in general?

There is a general solution for Intel HDA sound
Edit the "/etc/modprobe.d/alsa-base" file

Code: Select all

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

Edit// In Goria the file is called alsa-base.conf so it will be

Code: Select all

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

add at the end

Code: Select all

options snd-hda-intel index=0 model=acer

I don't guarantee that it will help, but there is a good chance
Model can be changed with each computer and sometimes you may need a "complicated" model
This is probably a solution for the hopeless cases - look in the post in the Ubuntu forums
