Network and sound card issues
The first time I entered the system, there was a sound, but after the data was saved, there was no sound. The reason seems to be that the System identification two sound cards, and the other is the HDMI sound card integrated on the video card. As a result, there was no sound after the data was saved.
Another issue is network issues. By default, I am able to access the internet, but when I plug in the wireless USB network card, it will not connect to the wired network and can only connect to the wired network.
Is that definition file missing?
Or how should it be configured?
There is currently no sound in the system.
If inserted

For sound this is what pulse audio just does.

Pulseaudio will automatically detect your audio output devices, including standard hardware devices and virtual devices such as pulseaudio-equalizer-ladspa. When there are multiple output devices (including virtual devices), pulseaudio will have no knowledge of your preferred (default) output device unless you select and save that information to the pulseaudio configuration file (/root/.config/pulse/default.pa).

Specifically, when booting or rebooting in an environment with multiple audio devices, pulseaudio reads the configuration file (if available) and restores the prior saved audio settings. If the configuration file does not stipulate a default audio device and volume level, then your preferred audio device and sound volume may not restore to your expectations.

Did you want to say it will not connect to the wired network and can only connect to the wireless network?

The sound is normal before saving the data, but after saving the data, there is no sound and it cannot run. Error prompt:
pulseaudio --start
W: [pulseaudio] main. c: This program should not be run as root (unless the -- system parameter is specified).
N: [pulseaudio] main. c: User configured server unix:/tmp/runtime spot/pulse/native, refused to start/auto spawn.
