Asked by Sandeep Subhash

Your ALSA information is located at http://www.alsa-project.org/db/?f=22572cb8d08447c999b93f39b3e2e0971b2498f7

Running fully updated 10.04 LTS 64bit on intel core 2 duo with GIGABYTE motherboard G31M - ES2L.
Sound card -
00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 01)

But no sound available.

I booted with 12.04 32 bit hdd on the same system - sound played without any hiccup. So hardware is ok.

Will be grateful if someone can guide me towards the solution.

This is a known issue with the ALC887 sound codec.

See the following bugreport for details:

https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/669092

Please run the following command in a Terminal:

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

ADD the following single line using the gedit editor:

options snd-hda-intel model=generic

SAVE the change to /etc/modprobe.d/alsa-base.conf

Then REBOOT and retest sound using headphones and speakers.

After rebooting, make sure all channels are UNMUTED and volume set to 100% in alsamixer and gnome-alsamixer

But you already gave the solution yourself. It is better to simply perform a clean install of Ubuntu 12.04 LTS, which is newer than 10.04 and is also a long term support edition.

Great. Sound is working fine.
But wired network stopped working after the fix.

Wireless is working on the desktop though. Any ideas?

The network thimble needed a little pressure from crimping tool on both end.
All working fine now.
Sound, email through citadel, file server through samba.

Many thanks to all the great wizards who understand noobs issues and manage to remotely set it right.
