= No sound on headphones attached to front panel =

In Debian Stretch the auto-mute function is not working as expected. In case there's no sound on headphones attached to the front panel of a linux machine, disable auto-mute as follows:

 * Run the command `alsamixer` in the terminal
 * Press "F6"
 * Select the on-board sound card named "0 HDA Intel PCH"
 * With the arrow (cursor) keys move to the slider labelled "Auto-Mute"
 * Disable auto-mute by pressing the "arrow down" key
 * Plug-in your headphones
 * Make sure the sliders "Master" and "Headphone" are unmuted by pressing "m"
 * Set the volume of the sliders "Master" and "Headphone" with the arrow up/down keys according to your needs
