I am new to Linux but really love Elementary for its simplicity. After noticing that my sound was quite poor in Elementary, compared to Windows 8.1, I have tried updating the sound drivers. I ended up downloading one from here but after a reboot, my sound icon was gone from the toolbar and no sound can be heard. In the setting > sound I see "Dummy Output" and running alsamixer says cannot open mixer: No such file or directory. I have Googled around without any success and many suggest sudo alsa force-reload but that returns

Unloading ALSA sound driver modules: (none loaded).
Loading ALSA sound driver modules: (none to reload).

I have lost hope and I am hoping somebody here can help. I have uninstalled the driver I have previously downloaded from the link above (maybe there are pieces left behind?) and purged reinstalled both alsa-base and pulseaudio but I still can not see the sound icon or play sounds.

Any help is greatly appreciated.
