Re-create audio devices

Sometimes sound stops working on my desktop, and I'm fairly certain that it's usually, if not always, correlated with usage of Flash. Regardless of the source of the problem, what would the easiest catch-all solution be to restore audio? Rebooting is an annoying last resort.
I would assume the simplest thing would be to destroy and re-create the existing sound devices (which would be simple to do in a script). What steps are required to do so? Is it as simple as reloading the appropriate modules?

Either way, the "audio disappears" problem stopped occuring to me a couple of months ago with some update, might have been a flashplugin update.

Thanks for the confirmation.
No dissenting opinion?
You didn't say anything about re-creating sound devices. I took that as an alternative solution to the bigger problem, not an objection to the specific solution.

I'm trying to multi-track using an m-audio device, I can record my guitar fine. However, I want to create a new track so I can record an acoustic tambourine over the top. Instead it records the original guitar as well as tambourine? its really annoying

I'm trying to multi-track using an m-audio device, I can record my guitar fine. However, I want to create a new track so I can record an acoustic tambourine over the top. Instead it records the original guitar as well as the tambourine coming out with a really distorted sound. I've managed to record over the top of a guitar before and add diferent riffs and sounds but I've tried all of the settings but its still not working. Basically I want to record different tracks without it recording my previous guitar riffs as well. Help would really be appreciated.

Ah that was it, thanks a lot common sense really but thanks for the help

I can't create new virtual audio device

Dear All,
I've two audio devices and I would create a virtual audio device with the input channels of both of them. I'v read that it's very simple. But when I click on the "+" button in the "Audio/Midi Configuration" application I'm not able to create a new virtual device. Both of real devices work perfectly.
My account is a system administrator.
Help me, please!

Great! It was hard, but now all work fine!
I removed these two files:
"Macintosh HD/Library/Preferences/com.apple.audio.AggregateDevices.plist"
"Macintosh HD/Users/YourUserName/Library/ Preferences/com.apple.audio.AudioMIDISetup.plist"
... the truth lies in small things!

Create Aggregate Device for audio - Admin User Required

In reference to the thread, http://discussions.apple.com/thread.jspa?threadID=1934270, I can confirm:
To create an aggregate audio device, you must be logged in as a user with admin rights. This was true on February 6, 2010 in Mac OSX Leopard 10.5.8.
Inconvenient, but understandable, because an aggregate device can re-route audio, possibly causing problems for other users who do not realize that's been done. Important for admin user to realize this.
Good to know that you need an admin userid.

You could ask about problems with the scheduled task here.

Is there a way to change the name of audio device inputs/outputs?

Hi there hope someone can help me. I use my macs primarily for music production and I have several audio cards both USB and PCI on my MacPro and I use external audio cards with my MacBook Pro both running Mountain Lion. As I have many different outputs I would like to rename them from their defaults, in other words I would like to rename "Headphones" to "Studio Monitors" and so on.
I have created Aggregate Devices which almost works as a solution as its possible to name them easily. The problem is with an Aggregate Device, the system Volume Control becomes greyed out and I can no longer change the volume using the Apple Keyboard.
I'm hoping that someone might be able to tell me which system file holds the names for the Audio Inputs and Outputs so that I can basically apply a bit of a hack to change my inputs and outputs to something a little more transparent? I don't mind applying tweaks to plist files etc as I have done this numerous times in the past to tweak some aspects of OS X.
The other solution would be to tweak the Aggregate Device settings to enable the volume control. Either option would be great especially when I am working on projects with friends who would be able to choose to listen to audio on a different set of monitors or headphones without having to ask me constantly which output is which.
All help appreciated!

These directions may be useful in the future but I was wondering how to change the actual name of the computer.
You know when you log into your iMac and then it loads all of your preferences?
Well at the very top of the login box, there is the name of your computer, I want to change that.
Not short names for Home folders.
Thank you though...
Any other suggestions or solutions?

[SOLVED] Default audio device no longer works after reboot

After today's reboot, the audio device no longer works. E.g., VLC says:

This is the console log:

The strange thing is that the sound card does in fact work; e.g. the sound test for "HDA Intel PCH", the first entry in my KDE Audio Settings, works. But the entry "default" does not and I suppose that is also the device that VLC is complaining about.
I've tried blacklisting the HDMI driver and switched to the other audio output modules in VLC. I've also checked I'm still member of the "audio" group.
Edit:
P.S. Solved this myself. I had a USB-to-MIDI adapter cable plugged in during boot, which seems to have been causing these problems. I suppose systemd thought it was a USB sound card? I was wondering why dmesg said something about USB sound when the computer doesn't have any USB sound devices. Hardware detection epic fail. Although I guess the cable counts as a MIDI device at least, so in a way it's correct.
So it looks like I'll always have to unplug the MIDI cable before rebooting.

FMLE 3.2 and 3.1 can't detect an audio device with Windows 8.1

FMLE 3.2 and 3.1 can't detect an audio device with Windows 8.1 x64 on an MSI GT72-2QD laptop. I tried 2 different webcams but the result was the same. Both the internal mic and the ones going with the webcams work fine with other software but when I try FMLE it looks as follows:
It says that there's no audio device connected (although the mics work fine elsewhere), the dropout is blank and the audio parameters are grayed out and inactive even with the "audio" box checked. Both versions of FMLE work fine with the same cams on a desktop which has all the same tech specs but uses Win 7 x64. Running FMLE in Win7 compatibility mode or reinstalling with register cleaning doesn't help. What can be done about it?

Hi Bob,
Thanks for the advice. It succeeded.
The steps I made was to make a disk copy of my original Windows XP disk using Disk Utilty. Then I renamed the disk copy into .iso. I copied the ISO file to my usb flash drive.
Than I started Parallels 7, created a new VM, selected the correct drive to install from (the usb flash drive) and volia, it worked.

Fix for Missing Audio Device in WinXP S

My sound card disappeared from the Sounds and Audio Devices Properties panel. I tried cleansweeping and reinstalling to no effect. I could watch my card disappear from the panel as Windows went through startup after I reinstalled it. My card , a Sound Blaster Li've!, was listed under the hardware tab but the drivers were listed as "Driver installed but not started". Creative Diagnostics said I passed the hardware detection test but failed the driver tests. I am using the drivers from the Li'veDrvUni-Pack(ENG) version .0.0..
I found this fix after searching with Google. The site is www.annoyances.org/exec/forum/winxpt/t06642744. It resolved my problem. I did use DH Driver Cleaner Pro to remove any Creative drivers. You need to know that the hardware scan and reinstall in step 6 can take several minutes. I also removed hidden copies of my Creative devices in step 5. The revealed hidden devices have greyed icons next to them.
Sincerely,
Weasel

RE>Hello to all,
I got much useful information from this topic, but none of them resolved my sound
problem. I use Windows XP SP2 on an Asus V7V8X and a Creative SB Audigy. I also tried
removing the SB card and enabling the built in VIA AC 97 without success.
Then I tried removing and adding back the Plug and Play Software Device Enumerator
as you suggested without success.
Then I went further reinstalling some of the kernel sound drivers and that resolved
the issue in my case so I describe my ste
ps.
First I suggest everyone to create a System Restore point to have something to return
in case of something goes wrong. You can boot XP to safe mode by pressing F8 at the
beginning of the Windows startup and select Safe Mode if the system doesn?t start
in normal mode and use System Restore there to go back to the working configuration.
Then try these steps only if the others mentioned here don?t help. I had everything
ok in Device Manager and every driver was running that should, compared to an other
working system, but the symptom was that there was no sound coming out from the sound
card. Everything was OK in the Device Manager, but in the Sounds and Audio Devices
Control Panel there was only the Voice recording option on the Voice tab, and the
MIDI music playback (without the sound card being in the list) on the Audio tab acti've.
The others like Voice playback, Sound playback, Sound recording and everything on
the Volume tab was grayed out.
. Create the restore point.
2. On the System Properties panel, Advanced tab, Environment Variables button, under
the User variables click New and create a variable named devmgr_show_nonpresent_devices
with the value of .
3. Open the Device Manager and select Show hidden devices from the View menu.
4. Under the Sound, video and game controllers group, find your sound card(s) and
disable it/them (don?t need to uninstall).
5. Then uninstall the following devices:
- Microsoft Kernel Audio Splitter
- Microsoft Kernel System Audio Device
- Microsoft Kernel Wave Audio Mixer
- Microsoft WINMM WDM Audio Compatibility Driver
6. Select Scan for hardware changes from the Action menu. Now the system should redetect
and reinstall the deleted devices automatically. You may get non signed driver warnings,
click continue.
7. Enable the devices you disabled in step 4. You may need to restart the computer.
The problem should be disappeared, you should be able to play sounds.
Good luck!
Ven

Hi
You should check if the microphone has not been disabled.
Go to control panel -> sound -> recording tab
There you should make a right click and should enable the both options called show hidden devices and show disabled devices.
Now you should see 2 microphone entries; one internal mic and second should belong to the external mic jack.
If you want to use the internal mic then mark it as default device.
Cheers

Fire Wire Audio Devices (M-Audio, MOTU etc) - Problems

This problem is discussed already. But only in connection with Bootcamp.
Apparently, there is a problem with the new FW Controllers uses in newer Apple models. Opposed to the traditional Texas Instruments controller, the new one create problems with FW audio devices. There is a big discussion on the RME page on that (without conclusive result, however). But I think the problem is more general and needs to be addressed:
Here is my problem: New Macbook pro, my M-Audio FW 1814 worked at the beginning )only garage band= with the beta version of the OS X 10. 5 driver, but than failed. Updated driver of m-audio )released end of april, did not help. My apple seems to recognize the external device, the software mixer shows movements, but there is no sound whatsoever coming in or out. Same with MIDI.
My question: Did apple give any statement on the problem? A lot of customers buy apple for making music, after all.
Cheers,
P

Yes, if you setup an aggregate device in the Audio Midi setup of your Mac combining the two FW devices. Open the Device editor->press "new device"->name it->choose the available devices in the menue below->hit ok/done/"fertig" (in german)->select this new device in Logic preferences as your Audio device

Can't create aggregate device?

Can anyone help me here, I know exactly how to create an aggregate device but when I go to hit the check boxes for various ins/outs it flashes like it worked for a second then appears back where it was on the list, unchecked. I have no idea what the problem is, but it won't let checks appear, it just appears checked and goes tot he top of the list for about a nanosecond and then appears again at the bottom unchecked, hence i cannot create aggregate audio devices.
EDIT: also, i've tried restarting, etc numerous times to no avail.

As a longtime user of Aggregate Devices, I can assure you that this issue is in fact real, and VERY new. What has happened since two weeks ago since I last used my setup?!?
Basically everything looks normal until you try to check the box to add the device to the list. You can click the plus sign, but when you try to check the boxes the check mark flashes in the box, and the "selected" item moves to the top for an instantbut then returns, unchecked to its original location in the list.
The forums and the genius bar have been no help (because I know more about this software than the staff) and I have tried varying the USB/firewire ports, only using certain devices, trying different devices... essentially everything I can think of save a system restore to earlier last month, which I do not have time to deal with right now.
This is a nightmare as I have a recording session tomorrow and have spent all day trying to figure out what is wrong... with no end in sight. Does anyone have a solution?
Apple, please address this issue ASAP!

Can't create aggregate device in SL

Just installed SL and i'm having problems with Audio MIDI Setup, i need to create a new aggregate device to use my mixer etc but when i click the + symbol, the new device will flash in the list and immediately disappear. Is this a bug or am i doing something wrong? This worked fine for me with the same setup in Leopard.

SOLVED!!!!! I spend about 5 hours one the phone with Cameron at AppleCare as well as some time on my own, and we FINALLY figured it out!
The important thing is that you can ONLY add aggregate devices from an admin account, but that may not be the only problem. It certainly wasn't in my case. So, here are the steps to follow:
1. Try adding/removing aggregate devices from an ADMIN account. If this works, you're good. If it doesn't, or if you're already on an admin account, try creating a new admin account.
2. If even a new admin account doesn't work, REINSTALL SNOW LEOPARD. If you just use the default install, it does an Archive and Install. It only takes about an hour, and you won't even notice OS X has been reinstalled except for the fact you'll have to reinstall the 10.6.1 update and any other misc. updates. Besides, it'll run a lot faster. It's so easy in fact that I'm going to start recommending you reinstall like this every couple months or so just to keep your Mac running in top condition.
3. NOW try creating aggregate devices from one or more admin account. It should work now. If it doesn't, then you have a different problem and I can't really help you much.
Hope this helps someone!

Creating Aggregate device?

I'm having trouble with creating an Aggregate deivce on 10.6
Are there any tutorials for 10.6 (not leopard as it seems to have changed in 10.6?)
I basically want to record in Soundflower but output and monitor on my Edirol USB interface?
I have both of these selected in Audio MIDI setup and what i thought was "soundflower INPUT and Edirol OUTPUT but can't seem to get it to work
Any info or tutorials on creating Aggregate Devices in 10.6 or help would be great
Thanks

Problem solved: Must be done from an admin account.

USB Headset detected, but not being loaded as a USB audio device.

Hey,
I just bought a Gigaware USB Premium Audio headset with Mic, and I'm currently trying to get it to work. It does show up under lsusb:
Bus 002 Device 004: ID 0d8c:0105 C-Media Electronics, Inc.
Bus 002 Device 003: ID 046d:c01e Logitech, Inc. MX518 Optical Mouse
Bus 002 Device 002: ID 06a3:8021 Saitek PLC
Bus 002 Device 001: ID 1d6b:0001
Bus 001 Device 001: ID 1d6b:0002
It's showing up as the C-Media Electionics, Inc. device. Unfortunately, for an unknown reason to me, it doesn't want to be set up as a sound card, as in DMESG:
generic-usb 0003:0D8C:0105.0004: input,hidraw3: USB HID v1.00 Device [C-Media Electronics Inc. USB Audio Device] on usb-0000:00:0b.0-5/input3
cannot find the slot for index 0 (range 0-1), error: -16
cannot create card instance 0
snd-usb-audio: probe of 2-5:1.0 failed with error -5
usbcore: registered new interface driver snd-usb-audio
As you can see, I get three different errors. I've googled all of these, but have come to no conclusion as to what they mean, or a solution to them.
Any helps much appreciated,
Alex

The format says Mac OS Extended. All of the settings were set during the disk image restore process. Even if I format the flash drive as extended journaled or some other format, all of these settings are reverted when I do the restore from the disk image. I will just copy all of the information that disk utility has so that you can see it.
