did you also unmute with alsa-mixer ?
Hi guys, just to let you know: I'm using Ubuntu Karmic on my macbook 5-5 with the following kernel:
and I have sound. The kernel I believe is "held" in this package:Code:szymi@ski:~$ uname -r 2.6.31-17-generic
After installing it, you'll have to edit /boot/grub/grub.cfg, find the following line:Code:linux-image-2.6.31-17-generic-pae
and adjust it so that grub boots to the right kernel.set default="0"
If you decide to downgrade, after booting into you new-old kernel remember to reinstall video drivers if you are using proprietary ones to get them to work. Also, you will have to create and run as root the following script (I found it somewhere around here: https://help.ubuntu.com/community/MacBookPro5-5/Karmic, can't remember where exactly)
The above script will install the right alsa driver for your system, and also it will remind you about unmuting sound. Easiest way to do this is to use gnome-alsamixer.Code:#!/bin/bash sudo rm -rf /lib/modules/`uname -r`/kernel/sound sudo aptitude reinstall linux-headers-`uname -r` linux-image-`uname -r` rm alsa-driver-snapshot.tar.gz wget ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-snapshot.tar.gz tar xf alsa-driver-snapshot.tar.gz cd alsa-driver sudo ./configure --enable-dynamic-minors --without-oss --with-cards="hda-intel" sudo make sudo make install
By the way, just a small hint for some of you: if you have something working and it stops working after an update, try booting into the kernel version you were using before update. Nine times out of ten it will magically get your Linux to work again. Generally, if you are inexperienced, always think twice before upgrading kernel if you don't have a valid reason to do so.

A couple more oddities I've noticed after upgrading to the 2.6.32 kernel:
1. My camera no longer works. Opening Cheese reports "No camera found!"
2. When I open my lid and Ubuntu comes out of suspension, the login prompt appears briefly, and then Ubuntu goes back into suspension. I have to manually press the power button and wait several minutes to bring it out of suspension.
Does anyone else have these problems?
well, cant speak for everyone, but I certainly don't!
One of todays security updates is linux-libc-dev (Linux Kernel headers for development). If I install this is it likely to be an issue for the sound on macbook pro 5,5? Sorry for the noob question but I've gained so much grey hair from this issue and now that I've finally got an installation that works almost flawlessly, the last thing I want to do is screw it up again.
I would be very surprised if this affected sound. All security updates should be applied ASAP - would you rather have broken sound or your entire machine compromised?
As far as I understand, the sound problem was/is related to the kernel.
Last time I installed a kernel update it blew my sound and nothing would get it back except a fresh install. I'd like to avoid that.
I'm very new to Ubuntu, and even more new to Linux at that. As the thread suggests I am also having a problem with my sound. I have literally read through all 22 pages and did what was written there. I still have no sound. Is there any help for me?

I have a Macbook Pro 5,5
2.53ghz Intel Core 2 duo
13'3 inch display model
Nvidia 9400M 256MB DDR3 shared
4GB DDR3 RAM
Ubuntu 10.10 Maverick Meerkat.
I can confirm that on this model the measures in post no.98 do work, I have full sound support after taking these steps. However, I had to change the kernel numbers to account for the updated kernel in 10.10.
