[SOLVED] Sound Card not recognized on Macbook (5,1)

Hello,
I had no problems installing Archlinux on my Macbook (5,1). In fact, the first time I followed the Wiki's instructions for installing ALSA, I could play sounds just fine. However, ever since my first restart, the ALSA daemon complains that I have no sound cards installed. lspci shows that it sees an audio device, but /sys/modules/snd no longer exists. I do not know much about useful diagnostic information for this situation, so please let me know what else could be of use.
Thank you,
Rob

I had forgotten that I installed OSS, which caused conflicts with a previously installed copy of ALSA. Once I removed OSS completely, rebooted, and went through the ALSA setup again, I had fully working sound. This problem can be marked as solved.

[SOLVED] Sound card not recognized

I tried following the ALSA setup guide on the Wiki to get my sound working but I don't think Arch recognizes my sound card. I found out from lshwd that the module is snd-intel8x0 so I modprobed that and snd-pcm-oss, changed the values in alsamixer, added myself to the audio group, installed alsa-utils, alsa-lib and alsa-oss and restarted everything but I still have no sound. Here's some output:
lsmod | grep '^snd'

The wiki says that if you have controlC0 and pcmC0D0p in that output then the modules have been loaded properly and they are both there so I'm not sure where to go from here. Your help would be appreciated.

you need to start alsa if you haven't already done so... /etc/alsa start
prolly better to run alsacoconf if you still have problems

GeForce4 TI Video Card Not Recognized Anymore?

For about almost a year, the fan on the GeForce4 TI video card would occasionally make a grinding noise, although it has always been easily fixed by lightly sticking a finger on the fan to stop it for a second and it would go back to normal.
However, about a month ago this little fix stopped working. The grinding noise was unbearable. After searching the Internet for a few minutes, I found out that I wasn't the only one suffering from this problem, and some even offered tips on how to replace the fan.
I followed the steps very carefully and made sure the card was not harmed. After installing the new fan, which was very easy, I stuck it back into the Power Mac and boot it up. However the monitor didn't find a signal.
I was glad that I installed Remote Desktop on the Power Mac so I was able to connect to it and see what's going on. I opened Apple System Profiler and noticed that the computer isn't properly recognizing the graphics card anymore! Instead of the very detailed information I'm used to seeing, this is what I saw below:
pci10de,a:
Type: VGA-Compatible Controller
Bus: AGP
Slot: SLOT-1
Vendor: nVIDIA (0x10de)
Device ID: 0x252
Revision ID: 0x00a3
I have no clue what this means as it seems like the computer still recognizes A video card. Also this also gave me the impression that the Power Mac is missing the drivers, but that's impossible as I haven't touched the software on the hard drive and nVidia drivers are part of OS X.
If the card is broken then fine, I'll take my losses and buy a new one as I would hate to just throw the computer away since it still more than fulfill my needs. But I just hope the AGP slot isn't broken.
Any ideas? Thanks in advance.

Just for clarification:
You have two systems based on the same MS-7008 mainboard, correct? Both use the same BIOS Version?
In one system, the card is functioning, running in AGP 3.0 Mode x8 and in the other, same mainboard model, what are the symptoms of "video card not recognized" besides the AGP 2.0 Mode x4 limitation?
I mean, if you can see the BIOS Setup, the card is putting something out on the screen, right?

Audio / Sound Card not working after Soundblaster.USB.Audio.Support.pkg

Ok, first - confess - it was stupid. I installed the Soundblaster.USB.Audio.Support.pkg package, which i downloaded from the internet, to make the harman Kardon Soundsticks (USB-Version) working, as nothing happened when plugging them in.
First, it ruined the mouse working after reboot and also disabled the internal sound card, not even as device available anymore. I fixed the mouse problem by installing IOUSBFamily-281.4.0-log(PPC).dmg
How can I make the sound card be available and working again ? I also updated to 10.4.11. Did not help ! Can you ? Thanks !

Welcome to the Apple discussions.
First, look in system preferences, accounts, and for your login account look at login items to see if there is a Soundblaster USB module that is loaded when you reboot your system. Delete it if there is one.
If you updated to 10.4.11 by software update, download the combo update from http://www.apple.com/downloads/macosx/apple/macosx_updates/macosx10411comboupdat eppc.html . The combo update is a complete update for all updates to 10.4, and installing the combo sometimes fixes odd things.

Graphics Card Not Recognized under Mavericks Update? MacBook Pro 8,2

Every since I updated my macbook to mavericks, my dedicated graphics card is not recognized under system profiler or any software on the computer. I have the Macbook Pro 8,2 (late 2011) and the upgraded dedicated GeForce graphics card from the factory. My system is just running off of the integrated intel graphics at this point and there is no option to switch back in system preferences. Is my card just dead in there or did mavericks ignore it? I have no other operating systems to check. Should I just make an applestore appointment and get it looked at?

Found the solution ... finally!
Go to your system preferences - energy saver and then check if your Graphics setting is set to »higher performance«. Somehow the update to Mavericks change this setting to »better battery life«
Now both cards are recognized and running ... however, watch out: since I changed that setting, my fans are going crazy! ... so I'm not sure if I should keep it. It would be much easier if one could change the setting all the time without the need to logout and login again ... well, Apple though good isn't the Holy Grail

[SOLVED]Sound Card No longer detected after pulseadio install

I recently installed pulseaudio and after the install my /var/lib/alsa/asound.state file was deleted or moved, anyhow now neither pulseaudio or alsa recognize my sound card. Is there a way to regenerate the original asound.state file ? i've already tried alsactl store but alsa apprently can't find my sound card anymore.
SOLVED: apparently the modules for the sound card were unloaded I don't know what caused it but it was sure annoying
SOLUTION:
modprobe snd-hda-intel ; modprobe snd-pcm-oss ; modprobe snd-mixer-oss ; modprobe snd-seq-ossa
Of course the modules you load will depend on your particular system, I happen to be using the Acer Aspire One netbook so I had an intel hda audio card
Acer Aspire One
120Gb HDD
1024mb ram
Intel N720 1.6ghz

yes i assumed it would be necessary for integration, am i to understand this was the root of the problem ?
ok so i was reading a gentoo forums post and decided to follow some of the fact finding there and came to some good information.
sound card is not found in /proc/asound/cards
sound card isn't in /dev/ anywhere
so it seems like it just up and disappeared

[SOLVED] Sound (snd_hda_intel) not working after resume from suspend

Using the latest kernel 2.6.30.4, On HP2133, whenever I get back from resume, sound is not working.
Running the following brings back the sound, but that is obviously a hack:
fuser -k /dev/snd/*
rmmod snd_hda_intel
modprobe snd_hda_intel
/etc/rc.d/alsa start
I have on my /etc/modprobe/50-sound.conf:
options snd-hda-intel model=laptop
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
Here's the exact hardware specification:
# lspci -nnv|grep Audio
80:01.0 Audio device [0403]: VIA Technologies, Inc. VT1708/A [Azalia HDAC] (VIA High Definition Audio Controller) [1106:3288] (rev 10)
Any idea where to look for this?

[SOLVED]
I downgraded to kernel 2.6.29 and the problem is gone.
Note: I also had X VT problems with 2.6.30.4 (xf86OpenConsole: VT_WAITACTIVE failed: Interrupted system call). Those were solved too by downgrading to 2.6.29.

Cirrus Logic sound card not working - Just a quick question (iMac 27-inch)

Hi, so as many have experienced, my sound card is not registering on my new iMac, on the Windows Vista side. I get sound out of the Mac side, just nothing from Windows.
I was wondering, would a USB sound card or sound pod solve the problem? I am not amazing with computers... But would buying one of those be a possibility?
I was looking at something like this...
http://www.emicrophones.com/p-1230-andrea-pure-audio-usb-sa-full-duplex-usb-soun d-pod.aspx
If anyone who knows what they're talking about could give me some input on this, it would be greatly appreciated. I do a lot of video editing on the Windows side, so having no sound would be an extreme burden.

Hi - I had this problem when I installed WIndows Vista (32 bit) on my i5 iMac. I believe I resolved the problems by finding the drivers on the OSX install disk. What I am struggling with is updating the video drivers - but that is another story...

Audio Science ASI5111 Sound Card not working with Aud. 3 Multi-track

I am using an Audio Science ASI 5111 Sound Card. I also used Audi
tion 3.0.1 on Windows 7.
The program suddenly freezes when using the ASI driver (not Audition driver) in Multi-track mode.
At times I get the R6025 error

Audio Science is aware of the issue. It has been solved by going back to an older driver. 3.12.07

Sound Card not compatible with WIN 7

I have a Dell 8200 Dimension Desktop (vintage 2002)?that I?ve just upgraded from XP Pro to Win 7. My Turtle Beach sound card no longer works since it is not compatible with Win 7. When I tried to install a non-Dell sound card, I found that the two sockets were not compatible with the Dell cables. I was told that I must have a Dell card since the plugs were proprietory Dell. I was given a Dell part number (38FRH) which supposedly was the card that would work as a replacement, i.e., be compatible with Windows 7. Dell no longer stocks this card since they stop supporting their computers after they are 5 years old.
Can?anyone help me solve my problem?

Which Dell cables? To the speakers? If so, time to change the speakers then.
Also try online such as eBay. Google for "Dell 38FRH". Ignore the Windows 7 drivers links. First few I found were fakes/scams. Scroll down. On the first page there were a couple of sites that carried it.
I would rather change the sound card [get something "modern"] and speakers than continue to use proprietary stuff.
Using Win 7 on an 8 year old system? Yeeesh.

HP 6120n Sound won't work bought replacement sound card not sure of what to do

HP 6120n - Using win 7 - Sound won't work
Tried restarting and Troubleshooter and it not not solve the problem
Bought used replacement sound card (30 day warranty) but not sure of what to do to install it or even if it is necessary

Hello @4u2bu,
I understand that the audio is not working on your HP Pavilion a6120n Desktop PC running Windows 7 and you are wondering it you should install the new audio card you purchased. I would recommend that you first try the steps set out in the HP Support document: No Sound from the Speakers or Headphones (Windows 7), which has been designed to address audio issues with computers running Windows 7.
Now if the above document does not work I would suspect a driver issue and since HP does not have audio drivers for your computer running Windows 7 I would suggest you go ahead and install the new audio card as it will have the needed drivers.
I hope I have answered your question to your satisfaction. Thank you for posting on the HP Forums. Have a great day!
Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!
Also be sure to mark my post as “Accept as Solution" if you feel my post solved your issue, it will help others who face the same challenge find the same solution.

Clicks & synch loss on firewire sound card (not due to sound card!)

Bonjour, from France !
Ok my firewire port does work when it has to mount a drive.
But it really makes the biggest mess in the universe when it comes down to streaming audio data to my external firewire sound card, a t.c. electronic konnekt 8. Ok ok I see you guys comming with the "read the notice of your soundcard you idiot" answers ! But it's not just me. My brother has a firewire m-audio audio interface on his intel iMac (first generation) and he is having the same mess, and a friend also had another m-audio firewire model and had the same problems. Of course, drivers are up to date.
The problems are : mainly random clicks and sound gaps when playing audio, sometimes lasting a few seconds - sometimes loss of synchronisation leading to strong sound degradation.
So my question is : this issue is obviously a general (mac ?) firewire related issue as several configurations have experienced it. Does anyone out there know how i could fix it ?
Thanx for your time,
Michael

All I can say I've got the same problems...
I've got a Saffire Pro 26 I/O and it was rock solid on my Powerbook, even with a FW400 drive daisy chained and recording 10 tracks at once.
The same interface on my Macbook Pro and Mac Pro is constantly crackling, losing sync etc.
It's also much more sensitive to FW harddrives sucking the bus dry on my Intel Macs.
I've got the same sort of problems with my Line6 USB devices (Toneport, PODxt, PODxt Pro) on both Intel Macs, although they were rock-solid on my Powerbook. (and I'm always using up-to-date drivers).
It's as if Apple dropped the ball with the new USB and Firewire chipsets on the Intel motherboards.
If anybody knows of a nice firewire interface that won't go flaky on the new Intel Macs (and can handle 8 channels of ADAT I/O) let me know

[solved] Digital Camera not recognized in device-manager

My digital camera "Canon Powershot SX120 is" is not recognized by the devicemanager. I have read Digital Cameras.
$ groups
wheel storage users printadmin
The "camera"-Group isn't needed anymore and this group doesn't exist on my system.
The Powershot SX 120 has a MTP/PTP connection mode (as the manual says). But:
# mtp-detect
Unable to open ~/.mtpz-data for reading, MTPZ disabled.libmtp version: 1.1.6

No raw devices found.

A gphoto --summary could be found here
There is no udev-rule for this camera. If i create one while copying a rule from a similar camera from /etc/udev/rules.d/69-libmtp.rules, and store it into /etc/udev/rules.d/69-canon.rules, the device-manager shows up. My udev-rule:

ATTR{idVendor}=="04a9", ATTR{idProduct}=="31e0", SYMLINK+="libmtp-%k", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1"
The device-manager shows me only the option to open with a file-manager. Doing so will result in an error:
The file or folder udi=/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:02.1/usb2/2-8/ do not exist.

Don't know what to do ... is a udev-rule necessary to bring up the message from device-manger? Or is the Camera not recognized as a mtp-device (the Camera has no such settings)? How could i figure it out?
With Digikam i could import Fotos, but i would do so with gwenview. I've tried to check it out with gwenview_importer:
$ gwenview_importer --udi '/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:02.1/usb2/2-8'
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
gwenview_importer: Missing required source folder argument.
(don't care about the different udi, i took this example from a former try) but i don't know, how to find out where the "source folder" is ...

I have solved this by making an extra udev-rule for my camera. See my adventure on forum.kde.org for details

IPHONE 4 NOT RECOGNIZED BY MACBOOK AIR

I recently rebooted my iPhone 4 and also updated my macbook air to the latest software update. Now, my iPhone is not recognised by my mac and by my iTunes .I've tried restarting and ect. What can i do?

IPhone 4s not recognized by MacBook Pro nor iTunes

I am currently running iOS 6.0.1 on my iPhone 4s and OS X 10.9.4 on my MacBook Pro Retina Late 2012. I recently reformatted my computer by means of a bootable OSX installer and I did a completely clean install. For some reason, my iPhone is able to charge, but not recognized by my computer nor iTunes at all. Nothing comes up.
I have followed the directions in the following:
http://support.apple.com/kb/TS1591?viewlocale=en_US
and
https://discussions.apple.com/message/24169239#24169239#24169239
Neither solution seems to be working. I have done the following:
reinstalled my iTunes multiple times
reset my networking on my iPhone a few times
restarted my computer
updated all my software
checked to make sure USB cables work
tried multiple iPhone charging cables
I'd greatly appreciate some guidance in regards to this. Thanks!

When you say a bootable OS X installer where did you get the installer? Is it one you created yourself?
You might want to try restarting the MacBook Air holding the Command and R keys. From Utilities on the menu bar, choose Install Mac OS X. That will reinstall using an installer from Apple. Install and see if that changes the behavior.
I did the following from this website:
http://www.macworld.com/article/2056561/how-to-make-a-bootable-mavericks-install -drive.html
Option 1: Use createinstallmedia
Hidden inside the Mavericks installer is a Unix program calledcreateinstallmedia, provided by Apple for creating a bootable Mavericks installer. If you’re comfortable using Terminal, it’s a relatively simple tool to use. The program assumes your account has administrator privileges.
Note: This method does not work in Snow Leopard. It works only in Lion, Mountain Lion, or Mavericks. (The resulting installer drive will let you install Mavericks over Snow Leopard, but you can’t create the installer drive while booted into Snow Leopard.) If you need to create a Mavericks install drive while booted into Snow Leopard, you should use the Disk Utility instructions, below.
Download the Mavericks installer from the Mac App Store and make sure it’s in your main Applications folder. (This means that if you followed my advice to move the installer out of your Applications folder, you’ll have to move it back, at least temporarily. The Terminal command I’m using here assumes the installer is in its default location.)
Connect to your Mac a properly formatted 8GB (or larger) drive. Rename the drive to Untitled. (The Terminal command used here assumes the drive is named Untitled.)
Select the text of this Terminal command and copy it:sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
Launch Terminal (in /Applications/Utilities).
Paste the copied command into Terminal and press Return. Warning: This step will erase the destination drive or partition, so make sure it doesn’t contain any valuable data.
Enter your admin-level account password when prompted.
The Terminal window displays the progress of the process, in a very Terminal sort of way, by displaying a textual representation of a progress bar: Erasing Disk: 0%... 10%...20%... and so on. The program then tells you it’s copying the installer files, making the disk bootable, and copying boot files. Wait until you see the text Copy Complete. Done. (see the screenshot below), which could take as long as 20 or 30 minutes, depending on how fast your Mac can copy data to your destination drive.
You now have a bootable Mavericks-install drive.
