Ubuntu / Apple :: MacBook (Pro) 5,1 / 5,2 - Master Volume Does Not Affect The Headphone Output
Jan 13, 2010
Whilst sound works for MBP5,1 / 5,2 under Karmic, it could definitely be better - mainly the master volume does not affect the headphone output, and the speakers don't automute when headphones are plugged in. However, I've finally got around to writing a patch for alsa which fixes this - the patch is against the latest version of alsa-drivers (1.0.22.1). If you want to test it (since so far I've only tested it on my MBP5,1 - any feedback from MacBook 5,1 / MB(P) 5,2 owners would be great too) follow these instructions: First make sure you don't have any versions of linux-backports-modules-alsa installed:

Just switched my laptop from that other operating system to openSUSE11.2. Everything works great except for one odd little bug. Both my speakers and headphones have output, are affected by the volume control and it even detects when I plug in headphones and stops output to the speakers. However the moment I adjust the volume, output to my headphones stops, and my speakers start.
Following is my multimedia information: [URL]

I'm running Kubuntu 10.10 32 bit on an old DFI KT600AL motherboard based system using the onboard VIA 3058 AC97 audio (because it supports front panel audio connections and none of the add-in PCI soundcards I have do). I have an old Gateway/STB TVPCI TV tuner card (mainly wanted the FM radio part to work) hooked up to the cd audio connector on the motherboard because the digital audio over the pci bus apparently isn't supported for this card (neither is the onboard analog mixer on the tv tuner card, I had to hack a CD-ROM audio cable and solder it to the audio outputs of the tv tuner module on the TV tuner card). When I use the master channel as the master channel (selected in Kmix) then as one would expect it affects the output volume of all other audio playing on the system except that which is being handled by the PCM channel. On Windows the PCM channel was also affected by the "Volume Control" slider such that ALL volume levels were reduced when moving the slider. I'm hoping someone can help me figure out how to make it work like this on Kubuntu.
First off I should warn you that I (like many users of older hardware that is not properly supported under PulseAudio) have uninstalled PulseAudio (because it's garbage) and am using Alsa to manage my audio hardware. I would think that there would be some way to do this using the 'amixer' application to add the PCM channel as a component of the 'Master' channel so that when the volume is turned down using the 'Master' channel control it will affect the PCM channel too (at least the output to the speaker jack, not necessarily the capture or mix volume though), but I'm not really any good at doing things from a terminal window and the options for the amixer command kind of confused me.

My volume control seems to have only three settings: TOO LOUD, VERY QUIET, OFF. If I adjust the Master volume slider from the Panel, only about the right 1/8th has any effect and if I slide it past about the 95% mark, I get no sound at all. At the far-right end of the volume control, I get total volume. It's basically like the slider only has any impact in the top 5% of it's space. Below 95% of the slide, there is zero volume.
It's so drastic, that one tap down of the volume button on my keyboard kills the sound (because it nudges the slider past that 95% mark). This happens in the Audio settings, etc., system-wide. If I adjust the volume for an individual app from within the app (MPlayer, for example) it behaves exactly as expected (that is, app volume works smoothly, it's just master volume that has this issue). I have run through most of the "obvious" things-- I'm wondering if I broke something by installing the extra KDE packages to get Amarok to work.

I'm running squeeze (last updated today), and everything has been working great. There is only thing that would simplify my life minutely..Anybody know how can I have the volume buttons on my laptop change the "pcm" channel volume rather than "master"? If they could control pcm, then I could adjust the volume coming out of my headphones or my computer speaker (both controlled by pcm, but not master...seems strange to me) with just one click.I tried to find this info online, but all results seem to refer to an older version. The simple "click here, set this" solution no longer is possible.

since updating my laptop to 10.04, I can't get any sound out of my headphones. If I plug the jack in, the sound from the loudspeakers turns off, but the headphones stay quiet.
I have run alsamixer and in fact the volume for the headphones is stuck to zero, and it's not possible to increase it.
My hardware config is posted here: [URL]
What I find funny, is that amixer reports that I don't have the capability of regulating the headphone volume:
Simple mixer control 'Headphone',0
Capabilities: pswitch penum
Playback channels: Front Left - Front Right
Mono:
Front Left: Playback [on]
Front Right: Playback [on]
I have also used the AlsaUpgrade script to get the latest version of alsa, but it still doesn't work.

is there a way to have my volume level change to a specified level when i insert my headphones to avoid having my ears blasted with music because i forget to turn the sound down when shutting off my computer last time? perhaps a alsa patch or a script?

since using 10.04 I have a big problem with my usb headset (freetalk everyman)
1. Problem: I cannot regulate the volume of the phones (output) anymore with gnome-volume-control. By default the volume is set to 100% which is way too loud. When I set it under 100% there is no sound at all. Values over 100% work.
2. Problem: The X server is freezing iregulary when I connect the headset and disconnect it, Magic SysRq works. I checked Xorg.0.log and found out that it recognizes the usb headset as keyboard:

Ever since upgrading to Karmic, I haven't been able to adjust master volume when my USB headphones are chosen as the output device. If I try to adjust my master volume (via the media keys on my keyboard or gnome-volume-control), the output volume doesn't change until it's entirely muted. I can adjust the master volume fine when I'm outputting through internal audio.I am able to adjust the volume fine on an application-specific basis, but this becomes quite a nuisance, especially when I switch between internal audio (where master volume is regulated) and USB audio (where master volume is always at full-blast). This worked fine in Jaunty, and stopped working once I updated to Karmic. My USB headphones are listed as "Storm HP-USB500 5.1 Headset".

I've been getting the hang of ubuntu. It's been a good switch from windows 7.
I'm having a bit of an issue which right now is causing me to regret deleting my windows partition. It'd be nice to have my dual boot set up right now.
Ubuntu is not recognizing my headphone output on my laptop.
I've been looking around but can't find a fix. Here's my alsa info script output.
Also, I'm running 64-bit ubuntu if that matters.

I'm a newbie, running Natty 11.04 on a Toshiba Satellite L645D laptop. If I boot the computer with headphones or an external speaker connection plugged into the headphone jack, I get no output through it. If I plug the headphones in after boot up, audio comes through fine, but there is no "auto-mute" on the internal speakers. If I restart/reboot after having had headphones plugged in, even if they are unplugged during the reboot, I again get no output through the headphone jack.
I have to actually shut the computer down, then start back up in order to regain the headphone audio.I've looked through previous threads discussing similar issues and tried updating, checking the ALSA settings (and I, like seemingly many other users, have no option to control headphone sensitivity, or whatever it was called). I don't have a lot of time to mess around trying to fix this, so I'm kind of wondering if I can just download another version in which this is not an issue? Maybe the stable release?

I've just removed PulseAudio and installed Envy24Control in order to make sound working with my M-Audio Delta 1010LT, it's working fine now, but the only problem is that the master volume control disappeared, and the buttons on my keyboard (volume + and volume -) are not working (with PulseAudio they were fine). Using Ubuntu 10.10

I have an imac and i recently decided to dual boot Ubuntu as well.
The sound is fine on the mac partition but the internal speakers dont work on the Ubuntu side.
headphones do work but the volume is oddly low
Nothing is muted on alsamixer, and I think i have the right driver for my sound card

I'm having a problem all the sudden with amixer. set Master 5% used to control the pulse audio master volume. Suddenly, it will only raise and lower the headphone volume. Pulseaudio works, but I no longer have a master volume at all.

On my Fedora 14 system, the gnome-volume-control-applet manipulates the Front channel, rather than Master (or PCM), which means I continually have to use alsamixer in terminal to adjust the audio volume in the other channels.In earlier version of Gnome (pre-pulseaudio?), this could be configured in the volume control preferences, but no more.Anyone know how I can fix this?My audio adapter is pretty standard Intel stuff. lspci: ode:00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller

I've got a Macbook Air and a verified 9.10 liveCD in the external superdrive. I can successfully boot to the CD, but when I choose "try ubuntu without installing", all I get is a blinking cursor in the upper-left of the screen forever. Any idea why it won't start? CD works fine on my Dell, that's why I say it's verified.

Today i went ahead and installed ubuntu on my windows desktop pc. I tryed the live cd and tested it out and everything was fine i then installed it using wubi. I then wanted to install it to my macbook ( bought in june 2009 ) and i booted the live cd and chose try ubuntu without any change to your computer. It booted a black screen with a white _ at the top then the screen went white and did nothing. I tryed it several times and nothing happend. I then said ok il maybe just try install it through wubi on my bootcamp partition and it all went fine until i got to the windows bootloader and chose ubuntu, it camp up finishing linux installation and where its meant to change and show the ubuntu symbol after ( i know because i've installed ubuntu on the pc) the screen went white. Nothing.

I have a first generation Macbook that shipped with Tiger. I don't often use the os x partition anymore, as I installed Windows XP on a 15 gig partition back when bootcamp was still in beta and I normally use that when I'm on my laptop. Since Tiger is rather old and the only reason I would want to upgrade to leopard is to have access to bootcamp again (they disabled access to the bootcamp application in os x, but I can still boot into windows), I have been thinking about wiping out my os x installation and using ubuntu instead. Does anyone have any thoughts on the pros and cons of totally removing os x?
The main reason I hesitate to just jump in and do it is because if I decide to install os x again I won't be able to install bootcamp again, unless I buy leopard. If I wipe out os x and install ubuntu, will I still be able to access windows in the same way? Windows uses bootcamp drivers to run properly, so I have never quite been sure if it is pulling something off of the os x partition or if it is totally standalone.

When I installed I noticed no sound was emanating from my computer and a red light coming out the headphone jack. s there any reason why there wouldn't be any working sound? Everything else seems to be working fine. I installed the additional drivers but the only ones listed were graphics and wireless.

Introduction: I wrote a very extensive and quantified tutorial and informational guide aiming to upgrade the latent information from the wiki's on MacBook Pro 5,2. An accidental toe tap ended with me bumping my head and pressing the X button on firefox. What happen had to be 1 out of a billionth of a chance. So this version will be simple and to the point, until I can muster enough patience to detail it all out again. Please correct any errors.
sudo apt-get install pommed - To get backlight keyboard working.
sudo apt-get install cheese - To get iSight working.
sudo apt-get install lirc - to get remote working (tested in XBMC)
sudo apt-get install bluemon - Pairs Mighty Mouse and Wireless Keyboard (optional)

I have installed it on my Macbook Pro 5.5 via rEFIt+ and the install works well except for the lack of sound. I've seen this issue posted about on the forums and I've followed the advice posted here as best I can with my limited knowledge. Terminal didn't recognise the aptitude (command not found). I guess that may be due to an older build of Ubuntu being used in the example?

I have downloaded the 64 bit iso and burned the CD-ROM per the instructions. The CD is verified. When I boot the mac, holding down the C key, I get a menu of options relating to Ubuntu. If I choose the trial run from CD then the CD drive starts up but the screen goes blank and I end up with just a blinking underline cursor in the upper left hand corner of the screen. Does anyone known if one can, and if so how, to boot the live CD on a Macbook Pro 5,2?
