after messing up witho Gnome and Unity packages (which now I managed to reinstall)
the sound on my computer is gone. I have Ubuntu 12.04 64 bit
The problem is that if I click on the "sound" icon,
the sound card is not recognized (the hardware only shows dummy output).
But if I type the audio device appears in the output:
Following some guide I have tried to give the two commands:
00:1b.0 Audio device: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04)
Subsystem: Samsung Electronics Co Ltd Device c0d8
Flags: bus master, fast devsel, latency 0, IRQ 45
Memory at c0210000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: snd_hda_intel
Kernel modules: snd-hda-intel
but this didn't solve the issue.
sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils
sudo apt-get install linux-sound-base alsa-base alsa-utils gdm ubuntu-desktop
How can I reinstall the drivers for my sound card and get the sound back?
(when I install Ubuntu from scratch everything works just fine,
so if I just could purge the installed packages and reinstall them
from scratch everything should work fine).
Thanks a lot in advance to all of you for the help.
