Can you provide a link or added in info on the suggestions? Particularly
the '/etc/modprobe.d/options' suggestions.
I'm interested because I have a laptop whereby the internal mic is no
longer working:

No intent to detract from the OP's problem, but it would be helpful to
know how you came up with the suggestions.

BTW:
sudo gedit /etc/modprobe.d/alsa-base
should be:
gksudo gedit /etc/modprobe.d/alsa-base.conf

and

sudo gedit /etc/modprobe.d/options
should be
gksudo gedit /etc/modprobe.d/options

See: https://help.ubuntu.com/community/RootSudo
[Graphical sudo]

'gksu' seems to be OK (this is what I use) as "gksudo and kdesudo simply
link to the commands gksu and kdesu"
