[Realtek ALC262, Speaker, Internal] No sound at all in Ubuntu 12.04

[Dhiren Dash]

Just upgraded from 10.04 to 12.04 and noticed I am not getting any sound. Used to work fine in 10.04. Also works fine with 12.04 with 2.6.32.41 kernel. Also I notice that there is no "Analog Built-In Audio" in sound settings.

Yes, it looks like pulseaudio only sees digital output. Please attach a verbose pulseaudio log: https://wiki.ubuntu.com/PulseAudio/Log

[pulseaudio] alsa-mixer.c: Removing path 'analog-output' as it is a subset of 'analog-output-headphones'.

Thanks for the log. The above error make it look very similar to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/946232

I suggest you try a workaround, such as plugging and then unplugging headphones, or the workaround in this comment: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/946232/comments/32

Many thanks for the solution. But I just managed to fix it using Pulse Audio Volume Control. Anyone else having this problem can just try this,

go to terminal and then type the following,

sudo apt-get install pavucontrol

Let the package install. After it installs, goto Dash, and search Pulse Audio Volume Control. Goto configuration and select "Analog Stereo Output". This worked for me. If this doesn t, try the solution as mentioned above by Dave Lentz.
