On a Chinese forum, a member has UnionTech OS installed. No sound is produced although the sound card and audio driver are detected. He ran "
aplay -l|grep card" and got the following:
Code:
card 0: PCH [HDA Intel PCH], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog]
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
He ran "
lspci -v | grep "Audio" -A7 -i" and got the following:
Code:

In Control Center, in the sound settings, no output device is found.
The CPU is Pentium G645. The Linux kernel is 5.10.0.
