Ubuntu Maverick wont work with my external speakers

Question

My laptop is running Ubuntu Maverick and sounds works great, but when I connect headphones or external speakers, nothing changes. Sounds keeps coming out just from the laptop speakers. I?ve tried all the devices in the "Sound Preferences" and still nothing. How can I solve this?

My Audio card is:

00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)

Answer 1

I don't know which is your laptop but this works on Toshiba Satellite and others.

Problem: Built-in speakers work. Plugging in headphones do not mute speakers.

Audio: Conexant CX20585
