Abstract (en)

[origin: WO2007044463A2] A method and system for performing automatic plug detection are disclosed. When a plug is inserted into an audio jack, the plug may be detected. Detection may occur at power up or upon insertion. When a plug is detected, a determination may be made as to whether the plug is a stereo plug or a mono plug. If the plug is determined to be a mono plug, audio information may be transmitted substantially using a first audio channel, such as a left audio channel. In contrast, if the plug is determined to be a stereo plug, audio information may be transmitted using the first audio channel and a second audio channel, such as a right audio channel.
