As my HP ultrabook has it's trackpad needing replacement, I purchased a cheap $198 Acer Gateway NE46RS1 laptop and installed Linux Mint 18 on it. This laptop has only an integrated speaker apart from headphone out.So, I found out that in alsamixer, it needs headphone volume increased so as to get sound from laptop speaker. Also, if I plug inn earphone, the speaker gets muted and it remains so, unless I again increase headphone volume. If I want speaker to work headphone volume must be turned up in mixer. I tried to save alsa state by running 'sudo alsactl store' which is not retaining on next reboot and gets muted. Also, see that front volume is missing.What I want is to re-assign proper volume control option for speakers instead of using headphone volume as well as to save the volume state instead of getting auto-muted on every boot.Please see the alsamixer controls and alsa-info.sh details:Alsa-Info ResultsMy sound card:cat /proc/asound/cards 0 [PCH            ]: HDA-Intel - HDA Intel PCH                  HDA Intel PCH at 0xf7c10000 irq 30amixer details:Simple mixer control 'Master',0Capabilities: pvolume pvolume-joined pswitch pswitch-joinedPlayback channels: MonoLimits: Playback 0 - 87Mono: Playback 83 [95%] [-3.00dB] [on]Simple mixer control 'Headphone',0Capabilities: pvolume pswitchPlayback channels: Front Left - Front RightLimits: Playback 0 - 87Mono:Front Left: Playback 82 [94%] [-3.75dB] [off]Front Right: Playback 82 [94%] [-3.75dB] [off]Simple mixer control 'Speaker',0Capabilities: pvolume pswitchPlayback channels: Front Left - Front RightLimits: Playback 0 - 87Mono:Front Left: Playback 87 [100%] [0.00dB] [on]Front Right: Playback 87 [100%] [0.00dB] [on]Simple mixer control 'PCM',0Capabilities: pvolumePlayback channels: Front Left - Front RightLimits: Playback 0 - 255Mono:Front Left: Playback 255 [100%] [0.00dB]Front Right: Playback 255 [100%] [0.00dB]Simple mixer control 'Mic',0Capabilities: pvolume pswitchPlayback channels: Front Left - Front RightLimits: Playback 0 - 31Mono:Front Left: Playback 0 [0%] [-34.50dB] [off]Front Right: Playback 0 [0%] [-34.50dB] [off]Simple mixer control 'Mic Boost',0Capabilities: volumePlayback channels: Front Left - Front RightCapture channels: Front Left - Front RightLimits: 0 - 3Front Left: 0 [0%] [0.00dB]Front Right: 0 [0%] [0.00dB]Simple mixer control 'IEC958',0Capabilities: pswitch pswitch-joinedPlayback channels: MonoMono: Playback [off]Simple mixer control 'Beep',0Capabilities: pvolume pswitchPlayback channels: Front Left - Front RightLimits: Playback 0 - 31Mono:Front Left: Playback 4 [13%] [-28.50dB] [off]Front Right: Playback 4 [13%] [-28.50dB] [off]Simple mixer control 'Capture',0Capabilities: cvolume cswitchCapture channels: Front Left - Front RightLimits: Capture 0 - 63Front Left: Capture 38 [60%] [11.25dB] [on]Front Right: Capture 38 [60%] [11.25dB] [on]Simple mixer control 'Auto-Mute Mode',0Capabilities: enumItems: 'Disabled' 'Enabled'Item0: 'Enabled'Simple mixer control 'Digital',0Capabilities: cvolumeCapture channels: Front Left - Front RightLimits: Capture 0 - 120Front Left: Capture 60 [50%] [0.00dB]Front Right: Capture 60 [50%] [0.00dB]Simple mixer control 'Internal Mic',0Capabilities: pvolume pswitchPlayback channels: Front Left - Front RightLimits: Playback 0 - 31Mono:Front Left: Playback 14 [45%] [-13.50dB] [off]Front Right: Playback 14 [45%] [-13.50dB] [off]Simple mixer control 'Internal Mic Boost',0Capabilities: volumePlayback channels: Front Left - Front RightCapture channels: Front Left - Front RightLimits: 0 - 3Front Left: 0 [0%] [0.00dB]Front Right: 0 [0%] [0.00dB]Simple mixer control 'Loopback Mixing',0Capabilities: enumItems: 'Disabled' 'Enabled'Item0: 'Enabled'
