GoTo /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common search for this: [Element PCM] switch = mute volume = merge override-map.1 = all override-map.2 = all-left,all-right delete it and paste in this area: [Element Master] switch = mute volume = ignore [Element PCM] switch = mute volume = merge override-map.1 = all override-map.2 = all-left,all-right [Element LFE] switch = mute volume = ignore After a reboot you have to enable LFE/PCM/Master again and set them to something like 60, via alsamixer and after that all works fine ___________________________________________________________________________________________________________________ #The full /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common file (with fix) is: # This file is part of PulseAudio. # # PulseAudio is free software; you can redistribute it and/or modify # it under the terms of the GNU Lesser General Public License as # published by the Free Software Foundation; either version 2.1 of the # License, or (at your option) any later version. # # PulseAudio is distributed in the hope that it will be useful, but # WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

If so it is added to the list of mixer ; elements PA will control, keeping the order it read them in. If a ; mixer element described here has set the required= or ; required-absent= directives a path might not be accepted as valid ; and is ignored in its entirety (see below). However usually if a ; element listed here is missing this one element is ignored but not ; the entire path. ; ; When a device shall be muted/unmuted *all* elements listed in a path ; file with "switch = mute" will be toggled. ; ; When a device shall change its volume, PA will got through the list ; of all elements with "volume = merge" and set the volume on the ; first element. If that element does not support dB volumes, this is ; where the story ends. If it does support dB volumes, PA divides the ; requested volume by the volume that was set on this element, and ; then go on to the next element with "volume = merge" and then set ; that there, and so on. That way the first volume element in the ; path will be the one that does the 'biggest' part of the overall ; volume adjustment, with the remaining elements usually being set to ; some value next to 0dB. This logic makes sure we get the full range ; over all volume sliders and a very high granularity of volumes ; already in hardware. ; ; All switches and enumerations set to "select" are exposed via the ; "port" functionality of sinks/sources. Basically every possible ; switch setting and every possible enumeration setting will be ; combined and made into a "port". So make sure you don't list too ; many switches/enums for exposing, because the number of ports might ; rise exponentially. ; ; Only one path can be selected at a time. All paths that are valid ; for an audio device will be exposed as "port" for the sink/source. ; [General] ; priority = ... # Priority for this path ; description = ... ; ; [Jack_InputDev] ; name = ... # Name of jack input device must contain this string ; code = Headphone | Microphone | LineOut | VideoOut # Type of switch events to listen to ; [Option ...:...] # For each option of an enumeration or switch element ; # that shall be exposed as a sink/source port.
