The speakers in my Sony Vaio Fit SVF15A1C5E don't work, while headphones do.

lspci -nn|egrep 'ultimedia|udio|sound|AC97|ac97|EMU':

00:1b.0 Audio device [0403]: Intel Corporation Panther Point High Definition Audio Controller [8086:1e20] (rev 04)

aplay -l:

cat /proc/asound/car*/co* | grep Codec:

Adding

options snd-hda-intel enable=1 index=0 model=basic

in /etc/modprobe.d/alsa-base.conf doesn't help.

Other suggestions?

As your headphones work, linux has your sound hardware driver. Sound issues in linux are mostly because of bad mixer status. Install and check the alsamixer or pavucontrol and check the mixer. In mixers look for any muted volumes and also test right/left sliders; sometimes some sound hardwares (mostly microphones) only work when mixer sets only left channel.

I had the same problem (headphones working fine, but no audio from internal speakers) with the same audio specs under Ubuntu 13.04, linux kernel 3.8.

I updated the alsa drivers according to the instructions given in the link below for my kernel version:

https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS

After installation of the new drivers (package oem-audio-hda-daily-lts-raring-dkms) and reboot, the sound worked perfectly.

Hope this update will work for you as well.

This worked like a charm, thank you! –  Nick Brown Sep 12 '13 at 5:37

This issue can be resolved by upgrading the kernel. Which might break the Wifi driver for this model tho.
