Hi I updated a friends computer from 11.10 to 12.04 and the sound stopped working in the built-in speakers. The computer is a Sony Vaio PCG-2J1L. I tried using the guide found here: https://help.ubuntu.com/community/HdaIntelSoundHowto and still no luck.

$cat /proc/asound/card0/codec* | grep Codec
Codec: Realtek ALC889

$cat /proc/asound/card0/pcm0c/info
card: 0
device: 0
subdevice: 0
stream: CAPTURE
id: ALC889 Analog
name: ALC889 Analog 
subname: subdevice #0
class: 0
subclass: 0
subdevices_count: 1
subdevices_avail: 1

cat /proc/asound/card0/codec* output can be found here http://paste.ubuntu.com/1043188/

If anymore information is needed just let me know and ill post it here. Thank you in advance for any help with this issue.

After searching around the forums found this answer

Append

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

with the following line:

options snd-hda-intel model=generic

rebooted and all sound worked

The sound on my 32bit 12.04 Xubuntu system suddenly went quiet.

Unknown as to why it suddenly changed.

I use an ancient Audigy card, but the laptop should be much simpler.

This is how I solved it...

Downloaded QasMixer, ran it and discovered that I had two "Analog Mix", one turned on and the other turned off. I switched them and sound returned.

Hope this easy fix works for you... (Click on image and select open in a new tab/window for better view)
