Why PulseAudio?

But first, some motivation. Why use a sound server these days? Doesn’t ALSA work now? Well, there’s 3 main reasons to rig up PulseAudio:

* Here’s the main one - PulseAudio can seamlessly play audio on any networked PC, regardless of what computer you’re actually at. What does this mean? Basically, you can hit play on your laptop and have the audio come out of the speakers attached to the desktop.

* Old programs that use OSS can be rigged to work correctly while having other sounds playing at the same time

* This one hasn’t been realized yet, but it’s also a very cool feature: audio can be manipulated per-application. While controlling this manually can already be done, it gets really cool when this is automatic based on the class of audio - for example, the music being turned down automatically when a VOIP phone call comes in. Someone worked on this as a Google SoC project, but he didn’t get very far (his implementation was a bit farfetched imo anyways)

Basics of Game Port,Gamepad and Joystick

Game Port

The game port is the traditional connector for video game input devices on an x86-based PCs. The game port is usually integrated with a PC I/O or sound card, either ISA or PCI, or as an on-board feature of some motherboards. The game port is no longer supported by Windows Vista and will thus likely largely disappear.

Gamepad

A gamepad, also called joypad or control pad, is a type of game controller held in the hand, where the digits (especially thumbs) are used to provide input. Gamepads generally feature a set of action buttons handled with the right thumb and a direction controller handled with the left. The direction controller has traditionally been a four-way digital cross (D-pad), but most modern controllers additionally (or as a substitute) feature an analog stick. The analog stick was introduced with the Atari 5200 controller, but did not reach popularity until the Nintendo 64, Sony PlayStation, and Sega Saturn.

Joystick

A joystick is a personal computer peripheral or general control device consisting of a handheld stick that pivots about one end and transmits its angle in two or three dimensions to a computer. Most joysticks are two-dimensional, having two axes of movement (similar to a mouse), but three-dimensional joysticks do exist. A joystick is generally configured so that moving the stick left or right signals movement along the X axis, and moving it forward (up) or back (down) signals movement along the Y axis. In joysticks that are configured for three-dimensional movement, twisting the stick left (counter-clockwise) or right (clockwise) signals movement along the Z axis. These three axes - X Y and Z - are, in relation to an aircraft, roll, pitch, and yaw.
