No sound after second reboot

[mohi2]

I'm a linux newbie!
Card - HDA Intel PCH
Chip - Intel CougarPoint HDMI

So I am having the sound problem like everyone else. There's only Dummy Output in sound settings. I've got a fix actually but it's not permanent.
Here's what I do.

First I remove alsa-base and pulseaudio with this command

sudo apt-get remove --purge alsa-base pulseaudio


then re-install it with this command

sudo apt-get install alsa-base pulseaudio



Removal of alsa-base and pulseaudio somehow always uninstalls my Unity Control Center so I install it as well.

sudo apt-get install unity-control-center


Then force reload alsa with this

sudo alsa force-reload


Reboot the machine and voila, I get the sound back and sound setting starts showing Speakers instead of Dummy Output.
No problem regarding internal external mic, speakers, headphones whatsoever.

But when I restart the machine once again, I'm back to square one.

Why it only works after first reboot then go back to Dummy Output.
What am I supposed to do? It's been two days already and I haven't found a solution yet.
Please help!

I had the same problem!
but mine took out a lot more than unity-control-center! (I am using ubuntu 14.10)

I had to re-install all these:

sudo apt-get install
alsa-base
indicator-sound
libcanberra-pulse
pulseaudio
pulseaudio-module-bluetooth
pulseaudio-module-x11
qtdeclarative5-ubuntu-telephony0.1
telephony-service
tone-generator
ubuntu-desktop
unity-control-center
unity-control-center-signon
