Date: 20 Aug 1994 00:00:01 EST In order to enable 4-channel audio, you must choose "4-channel mode" from the 'Options' menu of apanel or make a call in your program to ALsetparams(3A). See the man page for ALsetparams(3A) for more infor- mation. Enabling the 4-channel mode will cause the electrical char- acteristics of your audio connections to change: the headphone jack will become a second line-level output (like the normal line-level output). The mic input will become a second line-level input *if* you have 'line' selected as your input source. If you have the input source set to 'mic', then the mic input will continue to behave as a microphone input. Lastly, when your machine is in 4-channel mode, the input and output sample rates will be locked together. Thus, changing the input or output rate in this mode will affect the output or input rate, respectively. You may also run 4-channel applications when the audio system in in 2-channel mode, and vice versa (2-channel applications work when the system is in 4-channel mode).
