Linux sound card settings (speaker and headset sound at the same time)

Linux sound card settings (speaker and headset sound solutions at the same time)-Linux general technology-Linux technology and application information, the following is a detailed description. This sound card is relatively new. It can only be installed with the official driver on windows. In linux, it is sound, that is, the Speaker and the headset are ringing together, and there is no way to listen to music at work. Then the problem was finally solved and the process was recorded as follows:

1:
Run lsmod | grep snd. The result is:
Snd_hda_intel 457780 4
Snd_usb _audio 100608 0
Snd_usb_lib 24960 1 snd_usb_audio
Snd_rawmidi 30336 1 snd_usb_lib
...
If you know that the sound card is intel, write down the name of snd_hda_intel in the first line.

2.
Then, View:
Cat/proc/asound/card0/codec #1 | head
The result is:
Codec: Realtek ALC883
Address: 1
Vendor Id: 0x10ec0883
Subsystem Id: 0 × 10190000
...
.
Next, download a document in the alsa source code. I downloaded the source code of alsa-driver, and then
Alsa-driver-1.0.16/alsa-kernel/Documentation/found alsa-configuration.txt
File.
Then:
Vim, ALSA-Configuration.txt,
Search for alc833 and find:

Haier-w66 Haier W66
...
Well, my current is haier. It is estimated that haier uses the same chip. So I noted down, haier-w66.
3:
Open vim/etc/modprobe. conf.
Add a row:
Options snd-hda-intel model = haier-w66
Restart the system, and the Speaker and headset can separately control the volume.

Because of different systems, the paths of the above files may be slightly different.
