    Maybe you've installed a new kernel. Try to recompile the alsa driver again for the new kernel!

    What about microphone? I manage to playback sound, but recording sound is a different matter, it seems to only record very faintly, even with volume on 100%.

    (I'm on a Macbook Pro 5,3 btw)

    Mine is the same. It seems to lack of a mic boost.

    Re: Sound on a Macbook Pro 5,5?

    After many an hour of struggling, I have restored sound on my Macbook Pro 5,2 running karmic beta running 2.6.31-14-generic on a 64-bit system (which I lost on upgrading from Jaunty to Karmic beta). The following may be helpful.

    Code:
    ~# sudo uname -a
    Linux kronos 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux
    The key thing I did, apart from following a modification of the instructions found at https://help.ubuntu.com/community/Ma.../Karmic/#Sound
    (the part about removing pulseaudio) and http://ubuntuforums.org/showpost.php?p=7979472&postcount=171
    was to modify /etc/modprobe.d/alsa-base.conf by commenting out the line with snd-hda-intel and adding a new line with a different options, so

    Code:
    ~# tail -2 /etc/modprobe.d/alsa-base.conf
    # options snd-hda-intel power_save=10 power_save_controller=N
    options snd-hda-intel model=mb5
    I experimented with several versions of alsa but 1.0.21 worked, so I ran this scrip (seen in many posts with minor variations, one of the the link above):

    Code:
    sudo rm -rf /lib/modules/`uname -r`/kernel/sound
    sudo aptitude reinstall linux-headers-`uname -r` linux-image-`uname -r`
    sudo wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.21.tar.bz2
    tar jxf alsa-driver-1.0.21.tar.bz2
    cd alsa-driver-1.0.21
    sudo ./configure --enable-dynamic-minors --without-oss --with-cards="hda-intel"
    sudo make
    sudo make install
    After this, I reloaded alsa using

    Code:
    alsa force-reload
    unmuted all channels using gnome-alsa-mixer after which I logged out, logged in. At this point, I had sound, although not using applications that typically rely on pulseaudio.

    Next, I re-installed pulseaudio and, after some experimenting, discovered that in Sound Preferences, I needed to choose under Hardware the profile "Analog Stereo Duplex" to both hear sound. But now it works!

    Hey, this worked, great, thanks.

    About battery life: i applied some of the scripts and activated laptop-mode-tools so now i get 3hrs max.

    Another problem: I cant dim the screen brightness anymore, I guess I need nvidia 190 for that. Anybody got it working?

    Re: Sound on a Macbook Pro 5,5?

    compiling works but only until the kernel is upgraded.

    i'm also concerned that compiling might get in the way of the official ubuntu/alsa fix at some later stage or is this not possible?

    is there somewhere we can vote on this at launchpad? has anyone reported it there yet?

    It has already been committed. With 2.6.32 sound works fine out of the box on my MBP.

    This happened to me today as I inadvertently upgraded to 2.6.31 kernel and now there is no sound again.

    Would anyone be able to indicate whether it is possible, and how to compile 2.6.32 kernel in Karmic?

    Also I tried to repeat the process indicated in this thread (i.e. restore kernel files 2.6.18 ) but for some reason the packages for this kernel could not be found by aptitude. I don't understand this as it worked just yesterday. Is it a matter of getting these packages from the jaunty repos? If so, which ones?
