Sound appears to be working but no sounds from speakers or headphone

Hi, I have had the same issue on this machine previously under fedora 29 and Ubuntu 18.04. I do not understand the linux sound system very well so I decided to install arch and tackle from the ground up (e.g. not starting on a system with full sound stack pulseaudio etc. installed like fedora or ubuntu).

Steps so far: installed base system, lightdm, mate desktop, alsa-utils.

Hardware:

# lspci | grep Audio
00:1f.3 Audio device: Intel Corporation 100 Series/C230 Series Chipset Family HD Audio Controller (rev 31)
01:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere HDMI Audio [Radeon RX 470/480 / 570/580/590]

cat /proc/asound/cards
 0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0x92720000 irq 57
 1 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0x92660000 irq 58

The device I am trying to use is the Intel HD Audio.

Output of alsa-info.sh: ALSA project upload

Drivers appear to be loaded?

# lsmod | grep snd

soundcore              16384  1 snd

When running alsamixer the "PCM" device is unmuted and appears to be fine.

Amixer output

amixer
Simple mixer control 'PCM',0
  Capabilities: pvolume
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 255
  Mono:
  Front Left: Playback 255 [100%] [0.00dB]
  Front Right: Playback 255 [100%] [0.00dB]

When I run "speaker-test" or "aplay somesound.wav" the commands seem to run fine but no sound comes out. Even when specify device e.g.

# aplay -D default:PCH piano2.wav
Playing WAVE 'piano2.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo

Any clues of where I can look next to try diagnose this problem? I have asked this question on the fedora forum and on stack exchange and received no relevant answers.

Re: Sound appears to be working but no sounds from speakers or headphone

The best bet you have on this is seeing if you can activate the correct jack with something like hdajackretask. FWIW this reminded me of this earlier thread where things also looked - and as far as I know, still look - bleak.
