Audio:
You may search for your audio modul here (via terminal):
zless /usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz

##or you may prefer to unpack the file.

Options found can be added at the end of the file
/etc/modprobe.d/alsa-base

e.g.
snd-hda-intel model=acer

you can open it with:
gksudo gedit /etc/modprobe.d/alsa-base

Backup the file before edit:
cp /etc/modprobe.d/alsa-base /etc/modprobe.d/alsa-base.backup

After finishing save+close the file, reboot.

You may find the codec, e.g. Realtek 883 in alsamixer at the top left, when you type in a terminal:
alsamixer

There you may also test all setting options available.
A GUI for this tool is: gnome-alsamixer
