I am a relatively new user of Ubuntu 8.10 (been testing Ubuntu since 6.10), and I faced some little problems that bugged me (probably some default settings that I don't feel right).
First of all, I currently use a test system (HP compaq nc6000) on which I explore the functionalities. When I plugged in my headphones to quietly listen to music, I found out that the speakers were still working while they were plugged, which could potentially disturb people when used in a library .
And by the way, I'm currently hooked on 8.10. The OS is getting very user-friendly in overall .
Auto-mute speakers when headphones are plugged
- Go into the Volume control () applet by double-clicking on it.
- Click on Preferences
- Check the entry Headphone Jack Sense
- Press Close
- Click on the new tab Parameters, and check the entry Headphone Jack Sense
At that point, when you will plug headphone in the audio jack, the laptop will system will automatically mute the speakers.
Simultaneously control the volume of both speakers and headphone simultaneously with the laptop's buttons
- Right click on the Volume control () applet
- Go in the Preferences menu
- Hold down the Ctrl key, and click on both entries Main volume and Headphone to make them both highlighted.
- Take note of the entry in the combo-box (mine is Intel 82801DB-ICH4 (Alsa mixer))
- Press Close
- Go in System -> Preferences -> Sound
- On the last combo-box, select the same entry seen earlier (ie Intel 82801DB-ICH4 (Alsa mixer))
- Hold down the Ctrl key, and click on both entries Main volume and Headphone to make them both highlighted.
- Press Close
From there, if you press the buttons on the laptop to increase or decrease the volume, it will now affect both the speakers and the headphones.
I hope this can help new users who might face this issue, and feel free to leave comments if there is something that should be added or modified.
