Unable to hear audio

[Vikram Vincent <vincentvikram@gmail.com>]

Hello,
The problem w.r.t. sound started when I did an upgrade recently.
The o/p of
# lspci -nn | egrep -i 's(ou)?nd | audio | media'
00:07.0 Audio device [0403]: nVidia Corporation MCP67 High Definition 
Audio [10de:055c] (rev a1)
and
# lsmod | grep snd
snd_hda_intel         311968  3
snd_pcm_oss            48288  1
snd_mixer_oss          21376  2 snd_pcm_oss
snd_pcm                89992  2 snd_hda_intel,snd_pcm_oss
snd_timer              28424  1 snd_pcm
snd                    65896  7 
snd_hda_intel,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer
soundcore              13088  3 snd
snd_page_alloc         15376  2 snd_hda_intel,snd_pcm

I tried reinstalling libasound2, lib32asound2, alsa packages, etc... but 
to no avail.
Previously I was using realtek-linux-audiopack-4.06c but now that too 
does not work and messes up the installed libraries.
Thank you,
Regards,
