and I'm not getting audio output when I plug in headphones. So I went to preferences >> sound, lanched that and then went to the input tab and for my auxiliary (headphone) output to work the "Internal Microphone Built in audio" device must be selected, see screenshot https://ibb.co/hm1c1M2 The problem is that linux mint never selects this device by default meaning that I get no headphone output so every time I use headphones I have to select it manually. Is there a way to tell it to use the "Internal Microphone Built in audio" device by default when I plug something in. Thanks this is my first post so please let me know if I'm doing anything wrong.

Hi HackerCop,

I had a similar problem on a Dell notebook. I had to setup the sound for my headphones everytime I've restarted my system. My solution is to store the alsa settings in a config-file and reload them within an logon-script. To save your sound settings execute:

Code: Select all

alsactl --file $HOME/.config/asound.state store

To load this config execute:

Code: Select all

alsactl --file $HOME/.config/asound.state restore

Then you can use a little bash-script which can be autostarted using the Startup Application program.

Thanks for your quick reply Oliver really appreciated it however its still not quite working I set my audio device correctly then I executed the top command:

Code: Select all

alsactl --file $HOME/.config/asound.state store 

and then added the second command to my startup applications like this: https://ibb.co/RYTPDHL (I've never used startup applications before I'm a linux noob but it looks very useful) hope I've done it right .

The problem is that when I click run now on my startup script it works but whenever I unplug and plug back in the headphones then the sound device changes and I have to set it back. I've tried restarting my computer obviously as its a startup script but the problem returns when I unplug and plug in again. Do you have any ideas?

It's possible using PulseAudio Volume Control (pavucontrol) instead of Cinnamon's Sound Settings will fix this.

If not, it would be good to see this output in working and non working cases:

Code: Select all

curl https://gitlab.freedesktop.org/pulseaudio/pulseaudio/raw/master/src/utils/pa-info?inline=false | bash | nc termbin.com 9999

It is a shame Pavucontrol does not have an applet to dock, but it did solve my problem, thanks mate!
