The PC I am working on is in a loud environment. If I need sound, I use the headphone. On my own account this is easy: I mute the speaker in the sound-setting. I am not the only user, others use the Guest-session. And that's what this question about:
Is it possible to turn off the speaker by default on a guest-session AND leave the headphone-output working?
If yes, how can I fix it?
I tried to loosen the speaker (hardware) connection but it is soldered to the mainboard.
The soundcard on the PC is:
HDA Intel at 0xfea78000 irq 44 /proc/asound/pcm ───────────────────────────┐ │00-00: ALC662 rev1 Analog : ALC662 rev1 Analog : playback 1 : capture 1│ │00-02: ALC662 rev1 Analog : ALC662 rev1 Analog : capture 1 Ubuntu 12.04LTS is running on the system, my account has all the (admin) rights
