SYSTEM AND METHOD FOR AUTOMATIC PLUG DETECTION

摘要

A method and system for performing automatic plug detection are disclosed (Fig. 11 ). When a plug is inserted into an audio jack, the plug may be detected (step 1105). 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 (step 1115). If the plug is determined to be a mono plug (step 1120), 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 (step 1130), audio information may be transmitted using the first audio channel and a second audio channel, such as a right audio channel.
