I have been engaged in multi-channel recently, involving the realtek console, so I should do it first! My realtek sound card is integrated with ALC892 on the gigabyte B85M-D3H. Document: ALC892 DATASHEET-7.1 + 2 Channel HD Audio Codec homepage?>? Product Information?>? Computer Peripheral ICs?>? PC Audio Codecs?>? High Definition Audio Codecs?>? 8-Channel?>? ALC892 compares and references the content of the following document within two weeks ~

Feature enabled!

Because the frame space is insufficient, a separate close-up is provided for audio mixing ~

In the upper-right corner, click device advanced settings and select: Enable the front and back output devices to play two different audio streams at the same time.

Click the folder icon below advanced settings of the device and select disable front-panel Jack detection.

 

Enable HD Audio 2nd output as the second sound card (Audio channel ). The difference from the rear panel output is that there is only a stereo output and it cannot be mixed by a stereo sound.

 

Some chassis will not automatically detect whether or not the front panel is inserted because of reduced cost. The front panel audio cable is incomplete. The front panel audio outlet on the Main Board has nine plug-ins, while the shrinking chassis is set to connect only four lines to the front panel, which only supports dual-channel output and single-channel microphone input.

The rear panel only displays microphone input at the lower right corner of the plug-in, the lower right corner of the motherboard, and the lower left corner of the chassis.

Some microphones do not have battery and power supply, but are powered from the microphone plug-in. I just tested the microphone on a desktop camera (USB-camera, 3.5 plug-microphone, and the two are independent ), this is the case.

This type of microphone can only input sound in microphone input mode, but it cannot work in audio source input mode.

However, if you have a microphone powered by your own power supply and Output Audio Signal current independently, you can work in both the microphone and audio source input!

At this time, the microphone differs from the line input in that it has the zoom-in function and microphone effect.

The microphone sound obtained from stereo sound mixing is produced by the playback volume (including amplification) and cannot be obtained after the microphone effect is processed.

From this point of view, the microphone function has its own unique circuit design.

Output of headphones and speakers (front speakers:

Port-D/E/F built-in headphone amplifiersPort-B/C/E/F with software selectable boost gain (+ 10/+ 20/+ 30dB) for analog microphone input

Uninstall the official Realtek driver and restart it. Use a windows Driver to verify the volume!

After windows universal driver is installed, the default volume is 25 and 85.

The volume is 100 output and 74 is input. Realtek's official drive volume is 54 in ~

Compared with the previous recording, it is found that the waveform of the general driver is opposite to that of the official driver and the source audio.

Listener, similar to the speaker Mode Under Realtek ~ The bass gain may come from circuit design!

30 output 74 inputs, compared to the official drive 30 output 54 inputs, the volume is small, indicating that the volume amplification level is different.

The relationship between the main volume control (software) and the output (plug current!

Figure 1: No audio task. Adjust the main volume without changing the output.

Figure 2 and 3 output the mute audio, adjust the main volume, and the background has already changed. Figure 3 raised when the main volume is set to 0.

Figure 4. Sound Card output noise is different before and after the audio task.

This operation is in a different situation in Mo Xie ~ There are various!
