alsa-info.sh data includes !!Amixer output that shows !!-------Mixer controls for card Creative

Front channel for audio playback is muted [off]

Simple mixer control 'Front',0
  Capabilities: pvolume pswitch
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 99
  Mono:
  Front Left: Playback 90 [91%] [0.00dB] [off]

to unmute mixer control:

amixer --card=2 sset 'Front' unmute

Output Select is set to use Speaker jack socket rather than headphone jack socket

Simple mixer control 'Output Select',0
  Capabilities: enum
  Items: 'Speakers' 'Headphone'
  Item0: 'Speakers'

To change mixer control to use Headphone jack socket

amixer --card=2 sset 'Output Select' Headphone

Surround Channel Config is set to stereo (2.0)

Simple mixer control 'Surround Channel Config',0
  Capabilities: enum

But in other topic, PulseAudio Profile is set to 5.1 surround output

Realtek audio not showing up in audio settings / can't be selected - #3 by SE_Lain
$ pactl list sinks

Card #1
        Name: alsa_card.pci-0000_02_00.0

        Properties:
                alsa.card = "2"
                alsa.card_name = "HDA Creative"

Active Profile: output:analog-surround-51

I suggest either change PulseAudio Profile to stereo output

pactl set-card-profile alsa_card.pci-0000_02_00.0 output:analog-stereo

Or if you want 5.1 surround audio playback:

  • sudo alsamixer --card=2 to view/adjust audio playback controls
  • Unmute and turn up mixer controls for channels Surround , Centre and LFE
  • Change Surround Channel Config from 2.0 to 5.1
