[SOLVED]I've sound on my speaker only if i plug-in headphone

[Fred34]

I’ve got another laptop where I installed Debian but I don’t have any sound on my mono speaker except only if I plug-in some headphone. (and when they-re plug-in I've sound on the speaker AND the headphone)

I can swap it in pavucontrol but when it doesn’t save it when i reboot Debian.

When I do pacmd list-sinks
I got :
ports:

Code: Select all

                [Out] Headphones: Headphones (priority 100, latency offset 0 usec, available: no)
                        properties:
                                
                [Out] MonoSpeaker: Mono Speaker (priority 100, latency offset 0 usec, available: unknown)
                        properties:
                                
        active port: <[Out] Headphones>

impossible to find Auto-mute in alsa

Code: Select all

amixer -c 0 set ‘Auto-Mute Mode’ Disabled
amixer: Unable to find simple control ‘Auto-Mute Mode’,0

when I do aplay -l
I got :

Code: Select all

when I do

Code: Select all

I got nothing

Try https://wiki.archlinux.org/index.php/Pu ... utput_sink

My laptop switches the headphone & speaker outputs if the microphone is disabled in the firmware ("BIOS") options, perhaps check that.

Thank you, I appreciate,

I read everything but I didn't find what i need. I checked the documentation of pacmd and found THE line command :

Code: Select all

pacmd set-sink-port 0 [Out] MonoSpeaker

It works amazing !!!
Now i need to setup in the autostart
So i tried to added it to my file ~/.config/lxsession/LXDE/autostart but it doesn't works
I tried with /etc/init.d/rc.local and /etc/init.d/lightdm

How should I do for you ?

[Fred34]

FOUND IT !!!!

I just added this line :

Code: Select all

set-sink-port 0 [Out] MonoSpeaker

on this file /etc/pulse/default.pa

Thanks again for you help
