In the sound card: different sounds, advanced sound card application tip set, many users may be dual-material users of speakers and headphones, therefore, a method is provided to enable these users to use both the Speaker and the headset without changing the wiring repeatedly: the Speaker and the headset are connected to the rear and the front audio output interfaces respectively, switch the back-end or front-end output as needed.
However, this is obviously a little troublesome. Every time you call up the sound card settings ProgramIn addition, not all sound cards (or integrated sound cards) support post-and pre-switching. Even many front-interfaces are actually connected to the back-end interfaces and cannot be implemented at all. So we had to seek other better solutions.
Currently, almost all sound cards are multi-channel, even if there are three output interfaces (MIC, waveout, and linein ), however, when selecting multi-channel output in the sound card setup program, these interfaces are redefined. For example, if the sound card of 5.1 is set to six channels, the MIC port is redefined, so that the microphone cannot be used. For general users, the speaker and headset are still 2.1. In this way, we can select the 4-channel mode: The waveout mode is connected to the speaker, the linein mode is connected to the headset, and the MIC mode is connected to the microphone. In fact, in most cases (in fact, when the application uses directsound output), the speaker and headset have sound at the same time, of course, if the sound source itself is 5.1 or higher, the speaker may be different from the headset output content: d
When you use media player or media player classic to play audio or video, you can find that both the Speaker and the headset have sound, so that if the speaker is not open, you can use the headset to listen to the sound. Winamp or foobar does not use directsound output by default, so you have to make some settings (for details, see the sound card ).
Of course, when using a 4-channel audio, the sound quality of the auxiliary audio channel (the original linein, usually connected to the headset) will be poor. If the sound card supports functions such as virtual 3D sound, you may wish to turn it on, in this way, the sound quality of the auxiliary channels should be better.
