No audio output from headphone jack in a Fujitsu N3410 laptop


Hi

I've tried installing FC4 and Kubuntu 5.10 and they both give me an identical issue: sound plays out of the internal speakers but if I connect a pair of headphones or external speakers to the headphone jack there is no audio output from that jack - sound continues to play through the internal speakers.

The laptop is a Intel Centrino based laptop and uses a Realtek High Definition Audio (detected on Linux as HDA Intel) onboard soundcard. I know its not a hardware problem because under Windows, plugging in anything into the headphone jack redirects the audio output and stops playback on the built-in speakers.

Has anyone faced this before or have any suggestions?

I've tried unmuting everything in KMix / Alsamixer but that doesn't help. I read elsewhere that its possible that the headphone jack is actually a line-out... however neither KMix nor Alsamixer give me an option to control line out.

Thanks

Kernel - 2.6.11-1.1369 (FC4)

Thanks. The first time I installed FC4, I actually upgraded to 2.6.14 kernel but the the problem still exists. I believe the thread you pointed to said that sound wouldn't work at all - whereas in my case it does work, only not out of the headphone jack. Like the thread though, I do notice that in mixer/vol control I have very few options, not even a Master volume option is given. I will try and see if upgrading just to 2.6.13 helps.
