I've installed Maverick on a Sony Vaio VPCEA24FM. I have no sound. I've gone through the guide at https://help.ubuntu.com/community/SoundTroubleshooting
up to the section titled, "Is the system recognizing your sound card?" When I run the terminal command in that step:
sudo aplay -l
I get the following response:
aplay: device_list:235: no soundcards found...
The machine does actually have an onboard soundcard; it works fine when I run Windows.
When I run hardware lister (lshw-gtk), this is what shows up for audio (see screenshot attachment).
Can anyone help me out? I really want to switch over to Linux completely, but I can't do it if I don't have working sound.
