== Configuring Hardware - Configuring Sound ==

Obviously, you'll want to have a computer capable of producing sound. First, you'll want to be sure you've configured the proper driver for your sound card in the kernel. To check which sound card you have,
'''$''' sudo lspci -v | grep Audio
The output should look something like this:
00:1b.0 Audio device: Intel Corporation Ibex Peak High Definition Audio (rev 06)
If you examine all of the output of ''lspci -v'' you should see the details of your audio device. If you've configured the kernel properly, you should see something at the bottom indicating which kernel driver and modules are in use.
Kernel driver in use: HDA Intel
If you don't see this, either you haven't set up your kernel correctly, or you need to load the module for the card. The module for the card above would be ''snd-hda-intel''. I'd probe the module using
'''$''' sudo modprobe hda-snd-intel
After probing the module, you can once again check ''lspci -v'' to see if the module and kernel driver are now in use for that hardware. To enable the module at startup, you'll need to add it to the file ''/etc/modules.autoload.d/kernel-2.6''.

		+	You may run into odd situations, such as your external speakers not muting when you plug in your headphone jack, or the headphone jack working and not the external speakers. Most of these scenarios are due to ''alsaconf'' not correctly detecting your hardware, or new hardware with minimal kernel support. Here is a handy list of alsa [http://doc.ubuntu-fr.org/audio_intel_hda \| settings] for the Intel HD Audio chip, which is common in many computers these days running Intel chipsets. You'll need to add the option provided for your hardware in ''/etc/modprobe.d/alsa.conf''.
