Strange Red Light In Headphone Jack MacBook 4,1

[MattFinck21]

worked for me too! Macbook 2,1 Ubuntu 10.10

Fully inserting the jack and removing it should do the trick. Repeat a couple times if necessary, try it slower, or faster. Maybe twist a little... Okay maybe I'm describing a different insert-remove-insert-remove activity here

No, really?

I'm on macbook pro 4,1 and ubuntu maverick but the solution:

amixer set IEC958 off

does not fix the issue permanently!
Every time I started ubuntu red light comes up from my jack input!
Also:

# alsactl store

does not fix the problem.

Is there a solution for fix that permanently?

Thanks a lot for any advices

There's probably a better way, but I just added a script with that command to my start-up applications.

i.e.

turnOffLight.sh:

#!/bin/bash
amixer set IEC958 off

And added the command
"bash /yourPathToFile/turnOffLight.sh"
to your start-up applications (found in System/Preferences). If someone has a better solution let me know.

turnOffLight.sh:
Code:

#!/bin/bash
amixer set IEC958 off

And added the command

Thanks a lot quickridge !
It perfectly works.
I know that it would be a better way to solve this issue but for now is a smart solution.
It was very annoying to make that every time on starting ubuntu system.
Good luck for you!
Bye.

The non-restoring on start-up seems to be related to Ubuntu overriding the stored alsa settings at login, although I have no idea how that happens. I'm gonna keep looking into it but for now, running the brief startup script as suggested by quickridge is probably the simplest solution. If I ever figure out how to fix this in a more traditional manner I'll post it here.

This works perfectly on my Macbook Pro 3,1. Thanks so much.

I have this issue right now. I wonder if it has something to do with the fact that I get no sound out of the headphone jack. Only sound on computer is through regular speakers. CPU is Macbook 2007 model 2.0ghz C2D 1.5gb RAM. Please help

I just want to mention that this also worked for me as well with 11.10 on my MacBook 2,1
