Built-in Audio Digital Stereo outputs no sound at all.

Post by SOYEONKIM » 2020/01/26 11:15:08

This is my first time using CentOS 8 and I have tried troubleshooting snd_had_Intel problems, following a lot of solutions on the Google but no good results.
Is this something related with a PC's old soundcard?

[skim@localhost ~]$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 3: Generic Digital [Generic Digital]
Subdevices: 0/1
Subdevice #0: subdevice #0

[skim@localhost ~]$ aplay -L
null
Discard all samples (playback) or generate zero samples (capture)
pulse
PulseAudio Sound Server
default
Default ALSA Output (currently PulseAudio Sound Server)
hdmi:CARD=PCH,DEV=0
HDA Intel PCH, Generic Digital
HDMI Audio Output

I raise Master volume to the maximum in AlsaMixer v1.1.9.
F6 suggests me
- (default)
0 HDA Intel PCH
enter device name...

Strangely, in AlsaMixer v1.1.9, when I choose 0 HDA Intel PCH, I can't find any sound bar, so I can't raise volume. I just choose default and unmuted.
I unmuted alsamixer v1.1.9 and pulseaudio.

[skim@localhost ~]$ lspci -vv | grep -i audio
00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04)

I guess should I do something with Codec?

I don't have idea , cause I fiddled with this problem for many days...
