The latest kernel is causing problems with my sound, which worked fine with an older version. As I have only Ubuntu installed, Grub is not getting displayed while booting. How can I manually choose my kernel version while booting?

The simplest way to display your Grub is to press and hold the SHIFT button while booting.

As an alternative, you can always displays Grub without it booting any particular kernel:

gksudo gedit /etc/default/grub

change grub_timeout to -1

finish off by running

sudo update-grub

Holding down the shift key while booting, will display the Grub menu. You can now select an older kernel version.

For selecting an older kernel as the default kernel, please see this post

Please, install the previous kernel with the following command:

sudo apt-get install linux-image-3.0.0-12-generic linux-headers-3.0.0-12-generic

Then reboot. You will be prompted to choose your kernel.

Let me know if it worked.

By the https://help.ubuntu.com/community/Grub2:

GRUB_HIDDEN_TIMEOUT=0

This setting determines how long a screen without the GRUB 2 menu will be displayed. While the screen is blank, the user can press any key to display the menu.

The default behavior is to hide the menu if only one operating system is present. If a user with only Ubuntu wishes to display the menu, place a # symbol at the start of this line to disable the hidden menu feature.
