Hi

I have an intermittent problem with my headphone output on my Acer TravelMate 2480 Laptop. I sometimes I get sound out of me headphones when I plug them in and sometimes not, even sometimes I get sound out of both the internal laptop speakers and the headphone.

found some info in an old thread here but the script is not working, I like the idea though.

I have tried everything I can think of to get sound out of the headphones when I want but I can't find the problem. I am using Ubuntu Jaunty.

You're not running widoze now. So if the software works sometimes, it works all the time as a general rule.

The weakest link there is probably the socket - perhaps a dry joint on the pcb or it's gettig old and dodgy. Both earphones and speakers working together sometimes would suggest this.

I would like to think this too but I have taken this laptop completely apart just for that reason and see if there was a way to possibly rewire and re-solder the plug on the mobo but apart from everything being very tiny it looked all pretty good so I put it all back together again.

I would really think it is a driver problem, because the times that it does do what it is supposed to do, it does it well without any distortion and crackly noises.

I guess I should boot my system into windows to see if it occurs there too, but that is a hassle as i have replaced my hard drive in this and the windows i put on does not have any drivers installed or whatsoever, so i need to to find my original hard drive and use that once more to see.

will get back here to report.

thanks.
