Ubuntu / Apple :: Can't Get Internal Microphone Working Well With 10.04 On IMac 27" I7
Apr 21, 2010
I'm making some tests with the internal microphone and I've managed to record sounds but the results have a very low volume. I mean, I have to put the input volume to the max and I still get a pretty bad result. I've checked too the input volume in the alsamixer but no way, can't get better results.
I am really struggling to get my the internal microphone on my iMac to function. I was able to get the sound working by installing ALSA Mixer and appending the /etc/modprobe.d/alsa-base.conf file with [options snd-hda-intel model="imac24"]. Input is not muted. That file is attached.
My gnome-volume-control recognizes an 'Internal Audio Analog Stereo' device, but it picks up no sound. Here's the chip information: Realtek ALC889A.
I installed Maverick on my 27 inch iMac (core2 Duo 3 Ghz). I weas able to get the sound working through the headphonejack but not the internal speakers. I tried both alsamixer, and pulseaudio cvolume control, but neither solved my problem .
On my white MacBook2,1 , the Internal Audio Analog Stereo device does work, and, in the "Sound Preferences", it shows up on the Output Tab. The MacBook2,1 has an internal microphone. In the "Sound Preferences", however, no device shows up on the Input Tab where it tells to "Choose a device for sound input", neither can I check or uncheck the Mute checkbox, nor can I slide the volume control bar. In sum, the internal Mic does not yet work. I need the Microphone for Skype etc.
Sound was said to work out-of-the-box already in Karmic Koala, but it didn't. Somewhere, I was then recommended to update to Lucid Lynx, which I did. On the page [URL].. it is, again, promised that the Sound will work out-of-the-box. It still doesn't. What shall I do? Boot Mac OSX, or get the Mic working? Here is what I have done sofar:
I'm not sure if I have a hardware or OS problem. Firewire on my old G3 iMac has stopped working. Previously I've used a scanner and an external hard drive (Iomega eGo) without problems while running Lucid. Now neither works with the iMac, though they both work when connected to a PC. Both the PC and the iMac are running the latest versions of Lucid.
I can't tell when the problem began since I don't use the scanner or hard drive that often. I did try booting using the live 10.04 CD for PowerPC and had no joy with either device.The LCD on the hard drive lights when connected to the firewire port so power is coming through. The scanner has its own power supply.Checking with lsmod I see that both the modules ieee1394 and ohci1394 are loaded.I suspect it's a problem with the hardware. Does any one have an idea how I can go about verifying that? I'd hate to bin an old faithful without first checking everything out.
When I first had partitioned, and formatted appropriately, I installed the newest version of Ubuntu available (Time of posting 10.4), on the partition made with bootcamp, rebooted into Linux with rEFIt Now once I booted into 10.4 I got to the desktop, it started asking me about restricted hardware drivers, so I went into System > Administration > Hardware Drivers, It then searched for the drivers, it found the STA driver, and the B43 driver, I am unable to allow both. So I went on to try ndiswrapper, I downloaded it off another pc, compiled and installed on the iMac. then I got the driver off the Leopard install disk, put that on my flash drive, extracted the files from the installer, put that on the flash drive, then I went back over to the machine in question, copied the file to the desktop, I used the cd command to navigate to the folder, then ran ndiswrapper -i bmcwl6.inf, I made sure that the inf and sys files were in there, so I didn't know what was going on exactly.
So then I went into the software sources, and enabled the cd as a software source, then went into Synaptic, and installed the drivers, it said the install was successful, however when I go back to enable it, will still refuse to activate, I have looked all around for solutions, I have even checked out other threads on this matter. The funny thing seems to be, is that everyone, or almost everyone who has this card on their computer, are upgrading to 10.04, when it worked on a previous version.
I recently installed Ubuntu 10.10 and everything went smooth. I was originally using Ubuntu 10.04 version installed via Wubu and decided it was time to make a true install of Ubuntu and decided to use 10.10.
I installed Skype and tried to have a phone convo, but the Microphone wasn't working. I tried to use yfrog.com to record a video from my webcam and the video worked fine, but no audio. I also tried the pre-installed sound recorder to record my voice but that also failed.
trying to use the internal mic for skype, with no such luck. its an HP Pavilion dv-XXXX (<<i want to say 5000 or 6000, but it isnt in front of me ATM), restarting didnt help, and everything is updated (Fedora 14).
After booting up from the cd, I noticed that neither my wireless keyboard or wireless mouse were working. after a while a different screen came up that allowed me to use my keyboard arrows to choose "try ubuntu without affecting your system". So I choose that option and got to the desk top but then i had no use of the mouse or the keyboard at all. I then ejected the disc by quickly pushing the power button in the back of the iMAC and once the disk was out was able to restart the computer.Now i am in a black screen that says that there is no bootable drive.I know about the option key at start up, but that is apparently not working because my keyboard is not being recognized
I just installed ubuntu 10.10 about 10 days ago, an experience that has been both amazing because its really hard for me to go back to windows already, and frustrating because I'm having a little issue: my internal microphone is not working.here is some relevant info:I had alsa 1.0.23 and decided to upgrade thinking it would solve my problems so I ran the script to install 1.0.24, and for a day or two I lost my sound, without getting back my mic, and just like that the sound came back.I read a lot of posts out there, and ,ade sure I unmuted my mic in alsa soundmixer and pulseaudio.
I have a Sony Vaio VPCZ128. It has a NVIDIA GeForce GT 330M GPU with CUDA Technology (SPEED MODE) and Intel HD Graphics (STAMINA MODE) (switchable). The Processor is an Intel Core i7-620M with 2.66 GHz and the Chipset from Intel HM57 Express chipset.
Finally I successfully installed Ubuntu 10.10 (mainly following the advice on [URL] and using his kernel). Every thing is working fine including sound (still a few minor problems with backlight and Fn F5/F6). But I still desperately try to get the internal microphone running.
I've got a handy new Lenovo G560 running with OpenSUSE 11.3 64-bit. After a normal out-of-the-box installation the laptop speakers failed to mute when I plugged in headphones and I was only able to regulate the sound for both the speakers and the headphones simultaneously. Then I installed a whole lot of ALSA stuff and my sound devices were recognized as "PulseAudio server (local)". Speakers muted when I plugged in headphones - a big yay.
Now, though, my microphone doesn't work any more. It worked before, I'd talked on Skype with it, but upon trying to make a call with Skype today I noticed that it didn't work any more. Sound's turned up in KMix, so everything should be okay - does anybody know how to get my microphone working again?
Just bought a laptop Packard Bell Easynote TJ61 with an internal sound card Conexant CX20561 (Hermosa) and successfully installed Ubuntu 9.10 64-bit. Only problem was that the microphone (internal and external) was not working in all applications (soundrecorder, audacity, skype etc). Output audio (eg- Rythmbox) worked fine with ALSA and PulseAudio.
Tried a LOT of stuff, but the decisive move was to add: options snd-hda-intel position_fix=1 model=laptop to the file /etc/modprobe.d/alsa-base.conf and reboot.
I have Karmic Koala 9.10 working (near) perfectly on my iMac7,1, as identified by
NOTE: See below for Lucid 10.04 update to these instructions
IMPORTANT: You need to complete the installation procedure while connected to internet via the WIRED network. Then you can enable the wireless by installing the restricted drivers, after the install is complete. Also the fglrx ATI Video driver is effortlessly installed via Menu > System > Administration > Hardware Drivers
The sound card gave me some trouble, as it is an Intel HDA Model, reported as 'Codec: Realtek ALC889A' by
It shows up in lspci as:
It sounded rather tinny at first, when I tried mbp3 and other model names. Then I added the following line to /etc/modprobe.d/alsa-base.conf :
After reboot, my sound is full and can be put much louder than before. Jack detection works. Some people might have to leave out the power saving options. See below.
Sources consulted are mostly the kernel documentation ( Enter into the terminal: sudo apt-get install linux-doc
The relevant info can be found in HD-Audio-Models.txt.gz and HD-Audio.txt.gz in /usr/share/doc/linux-doc/sound/alsa )
I just installed the latest version of Ubuntu on my intel-based iMac with OSX 10.6 (Snow Leopard), but I don't know how to bring it up.
I partinioned my hard drive for it. I inserted the CD and pressed C when restarting my computer for it to come up, then I installed it on the partition. It was done installing and said the computer must restart now, so I pressed OK. I got a black screen with a bunch of white text saying something about an error. It was pretty much "frozen" (I didn't know how to get off the screen), so I turned off the power manually by pressing the power button. I turned the power back on, but I get no option for Linux. I tried putting the CD back in, and it boots from the CD but it's still the non-installed version. So I thought maybe it didn't install, so I pressed install again. It said to choose where to install it, but my partition of free space said Ubuntu was already installed on it.
I'm really confused and don't know how to get it to start up when I turn on my computer.
EDIT: Here's some more info about my mac incase you need it:
iMac OSX 10.6 Snow Leopard Intel 4 Gb of RAM 250 Gb hard drive (29 Gb partitioned for Linux)
I remembered about my old iMac G3 and currently had OSX 10.2.8 installed on it but its too old to support flash so no ..... or anything (why I stopped using it) I do remember gnash working on it along time ago when I had Ubuntu 4.10 installed, gnash is just really glitchy but that was quite a long time ago I used it so I'm only assuming they have made some updates as Ubuntu progressed.
I tried have now tried 4.10, 6.04, 6.10, 7.10, 8.04, 8.10, and 10.10 all for ppc using the alternate installer cause the desktop installer just makes the iMac restart when I tried it with 8.04 I think it was so I just stuck with the alternate installer method and EVERY one of those versions of Ubuntu fails to install the base system..
I don't know what it is or why this is happening because that is the same disc I used before with 4.10 and it now cant find a file, I tried re downloading 4.10 and burnt it again on my dads laptop (Toshiba Satellite with Ubuntu 10.10) at 8x on a CD (the iMac has a CD ROM only). I can't figure out what to do, I just downloaded the Desktop installer for 10.04 and the alternate installer for 10.04 as well and I'm going to burn both of those and see what happens.
Every install I tried to do I did a full whip to the hard drive so its a fresh install of ubuntu only. I thought maybe something was wrong with the hard drive now so I tried 10.2.4 again and it installed fine and wanted me to update to 10.2.8 again so I turned it off and tried 10.10 again and nothing is working. It's going on a week soon I've been messing with this old computer trying to get it working and everything is failing on me
my partner and I have been trying to wipe the mac os 9.2.2 (UK version) and replace with ubuntu 7.04 (previous forums have mentioned this is the most stable version of ubuntu for the G3).
We bought this iMac G3 the other day, cheap, for our sons room... homework, research, music etc. He's used to the windows system that the Mac os looks both boring and confusing to him. so we thought we'd go in between and use the ubuntu os.
Any who! downloaded the iso for ubuntu 7.04, burned the iso image, alternate cd install of course. the only problem we are having is getting the disc to boot at start up on the iMac. (cd rom doesn't have a tray, I've seen this question asked before). the cd burned fine, the disc works on other systems. but when it comes to boot up on the iMac, nothing happens. press and hold down c, cd drive turns the discs a few times then carries on with the original mac os 9 start up.
I can't install any flavour of Ubuntu 9.10 onto my new iMac G3. Here are its specs:
iMac G3 New World (Indigo) 350MHz G3 Processor 192MB RAM 6GB Hard Drive Slot Loader (CD only - not DVD) Mac OS 10.3 Panther
The drive does work - I've played music from CDs on it, and it does allow me to view PDF files stored on data CDs. I can even view the Ubuntu CD through the Finder on the desktop. It just really doesn't want to boot from the CD.
I've tried multiple Linux distributions (all of them PPC compatible).
I want to install Ubuntu on a PPC iMac.It is running 10.2.8.I'm looking for a ppc version of Ubuntu that will fit on a CD-R, the iMac has no DVD reader.Where can I find this?Also, I'm not sure how to get the iMac to boot from disc. It doesn't seem to respond to holding 'c'. Also, when I hold 'option' during boot up it shows me a screen with a picture of a lock, it wants me to fill in a password, but my user's password won't work.
I installed 9.10 and the graphic driver for the ATI video card. After reboot all was ok. Then I run a system update, it found almost 250 packages to update. After installation, rebooted machine and it hangs on boot.
