I added the jack_detect=no hint and I checked the mixer controls using amixer; "Input Source,1" is set to "Front Mic" already but I can't figure out how to set Independent HP to "Enabled". I tried all variants of amixer -c0 sset "Independent HP" Enabled, Item0=Enabled, True, 1, yes etc. (sget works fine) but it always either says "Specify what you want to set" or "Invalid command!". I can't find any information about setting enum mixer controls in amixer OR any other way (apparently its not supported by the alsa python library). Also where would I change this permanently? I also added two new mappings (it wouldn't work if I reused the existing analog-stereo) and copied the "example for a multi-sink profile", and added this to the default profile-set: [Mapping alt-analog-stereo-back] device-strings = hw:%f channel-map = left,right paths-output = analog-output-lineout paths-input = analog-input-front-mic priority = 10 [Mapping alt-analog-stereo-front] device-strings = hw:%f,2 channel-map = left,right paths-output = analog-output-headphones paths-input = analog-input-front-mic priority = 10 [Profile alt-analog-stereo-back+alt-analog-stereo-front] description = both output-mappings = alt-analog-stereo-front alt-analog-stereo-back input-mappings = alt-analog-stereo-back skip-probe = yes I can now select "both" in pavucontrol, but it doesn't add two sinks, I can only select the "Line Out" port in the Output tab. About the > Don't mute surround71 playback switches and don't turn off volume lines; I'm not quite sure which lines of all the ones in the path files you are referring to. Right now i commented a few in the two files: in the headphones file: ;; [Element Surround] ;; switch = off ;; volume = off and in the lineout file: ;;; [Element Headphone+LO] ;;; switch = mute ;;; volume = merge ;;; override-map.1 = all ;;; override-map.2 = all-left,all-right ;;; required-any = any [Element Master Mono] switch = off volume = off [Element Line HP Swap] switch = off required-any = any ; This profile path is intended to control line out, let's mute headphones ; else there will be a spike when plugging in headphones ;;; [Element Headphone] ;;; Switch = off ;;; Volume = off If I understood you correctly than all I need to do is flick the Independent HP mixer control on and I should have two sinks when restarting pulseaudio, but I have no idea how to.
