Adding aggregate sound device and 10.6.4

I just got a new Numark C3USB external sound mixer - with two USB inputs, and I'm trying to configure it so that I can connect both USB outs on my Macbook Pro (10.6.4) to Ch3 and Ch4 on the C3USB via two USB cables. However both ports are recognized as "USB Audio Codec" and play out of the same channel. I've read similar threads, but no solution for my particular application (Virtual DJ 7.0). Any thoughts? I've posted this question to the Virtual DJ site, but I thought this might be a Mac issue...
When I go to Audio MIDI Setup, the "+" adds an aggregate device for a split second, then it goes away. I think this is what I want to do... My user account has admin privs.
Need this tomorrow! Anybody have some guesses?

Problems with aggregate sound device

Hi,
when making an aggregate sound device in the Audio Setup, I only get one source to pass it's sound through the device. I've tried different sources: USB-microphone, usb-soundcard, internal microphone, soundflower and so on. They all work fine, but only one at a time. If I add multiple devices only the first one added will work.
The odd thing is that the level indicator, e.g. in Quicktime, shows sound from both sources, while only the first one added will be recorded.
And yes, I've set the sampling rates of all devices to the same value (44100,0 Hz).
Please help!

And to add to the saga one last time, I can't reproduce that success reported in the last message.
Does anyone know where on the filesystem these settings are actually stored? /Library/Preferences/com.apple.audio.DeviceSettings.plist seems like a likely candidate, but it doesn't say anything about my aggregate device that Audio MIDI Setup clearly shows... And /Library/Preferences/com.apple.audio.AudioMIDISetup.plist is just a very short file containing a serialized ObjC object or three...

Should my Computer shows as a device on the Control Panel\Hardware and Sound\Devices and Printers.

Should my Computer shows as a device on the Control Panel\Hardware and Sound\Devices and Printers.
Should it? I have an HP p6653w w/ a c7280 all-in-one printer.
My computer is showing as a device with 'trouble' and it says it has NO driver for it.
What would happened if I removed that device? Would I again lose the ability to print ??

Do you have Windows 7? If so it is normal for the computer to show up in the "Devices" list. I would suggest you do not delete it.

HT201301 After file sharing, if a new iTunes account is added to the device and synced, will the shared files be deleted?

My company would like to give out iPads to contest winners and have company owned "propoganda" loaded onto the iPad for the winners to view. Most likely videos, word documents and possibly more. I have a couple of questions about that.
Without building a file sharing app ourselves what apps are the best for file sharing through iTunes?
If we load files onto a device using our iTunes Account, then hand it over to the winner and they put their iTunes account on the device and sync it, will the files we pre-loaded be erased?
If so, are there any other solutions to accomplish this task?
Thank you for any help you can provide!

Syncing with your computer will delete data from his phone but you should be able to restore his backup.

However, he won't be able to play music purchased under a different iTunes account than the one his phone is signed into. He can change the account to yours, but any apps he purchased under his account will no longer update, and any purchases he makes will go on your account.

Multi output sound device and 5.1 sound

Hi,
I have following setup:
TV is connected to the Mac Mini, with HDMI Cable.
Amplifier (5.1) is connected to the Mac Mini, with Toslink cable.
In addition to that TV can pass sound to amplifier through another toslink cable.
Currently my setup works perfectly:
When I set sound output to HDMI, TV recognizes 5.1 sound (also it can be passed to the amplifier).
When I set sound output to digital audio, amplifier gets 5.1 sound.
Note: 5.1 sound works when I play movies from VLC. In audio setup (in preferences and midi setup) there is only possibility to have 2 channels.
What I want to do is to have the same output to both devices.
I created multi output device, for HDMI and digital audio, and devices get only stereo sound.

Thank for your reply, however it didn't solve my problem.
I can send surround sound over hdmi to TV, and then TV can send it to the amplifier.
What I can not do is to send surround sound directly from Mac Mini to TV (via HDMI) + amplifier (via toslink) - so that I can switch off TV and have sound on amplifier.
I also have the multichannel options options greyed out (as described in this thread: https://discussions.apple.com/message/19584051). But what I am talking about is sending sound as Dolby (which can be done with VLC), not PCM.

Usb composite device is an older usb device and might not work in USB 3

I recently bought one Lenovo Yoga 2 11 laptop running Windows 8.1 (64 bit).
When I try to connect my old Brother MFC-3240C printer using USB (2.0), it doesn’t work.
Below are the steps performed:
Connected the printer to USB 2.0 port on laptop (on the right side). Automatically installed the printer driver (no exclamation mark beside printer icon)
When the printer didn’t print, I tried to use troubleshoot as below:
Control Panel->Hardware and Sound->Devices and Printers->Right Click on Printer Icon->Troubleshoot.
It came up with USB composite device is an older usb device and might not work in USB 3.0
Removed the printer and re-installed the driver. It is all the same.
Any help will be greatly appreciated.
FYI – the same printer works fine with my older laptops running Windows 7.

Already checked Brothers website for the printer drivre for Windows 8.1 (64 bit).
It says ... The built-in driver is already included with Windows® Operating System or is available through Windows® update.
So, installed the default driver for the printer that is available with Windows 8.1.
Even connected the printer with USB 3.0 port on the laptop, but it is all the same.

Sound device selection

a feature i would like is for sound device selection. i have my pc connected to a usb headphone audio device and my surround amp through onboard soundcard. having to go into windows sound settings and change the default sound device through control panel is a slow task. thus changing all programs that do not handle sound device selection to operate on the windows default sound device and then needing to change it over and over. simply changing the sound device within firefox then starting the audio/video playback will initiate the new sound device.

Hi,
Unfortunately as we forum-dwellers aren't Mozilla employees ( for the most part ) we can't do this for you. Try contacting Mozilla for feature requests.
Sorry about that!

No sound Device detected on HP Pavilion m7650n

What's Up Peeps!! Happy Holidays to everybody.
Yesterday, when I logged on to one of my sons' computers - there was no sound coming out of the speackes on the HP w22 monitor. I checked to make sure it was plugged in and it was. According to one of my sons, the problem occurred a couple of weeks ago.
I then went to HP trouble shooting and followed all of the instructions will no success. To make a long frustrating morning short. I typed msinfo032 and got into property information. I checked on Components then Sound Device. The screen in totally blank.
How do I reinstall the sound device and get the computer to recognize it?
I do appeciate any help anyone can give me.
Peace,

How do I delete a sound device?

How do I delete an output sound device and how do I delete an input sound device? I don't know much about computers so I would prefer step-by-step instructions. Thanks in advance.

Multiple sound devices mayhem (wiki not helping)

In my computer, there are 3 things wanting to pretend to be sound devices:
*) The motherboard (HDA Intel PCH ALC892)
*) The USB webcam, logitec quickcam 9000 Pro --> Microphone only, yet this thing manages to confuse Linux into thinking it's a soundcard, thereby disabling all sound
*) The nvidia graphics card. Don't ask me how a graphics card can make sound, but does a hdmi port maybe have the ability to make sound or so??
Anyway, while using Skype, sometimes microphone works, sometimes it doesn't. I want my own microphone (plugged into the motherboard on the rear side) as mic, NOT the webcam, and definitely not the graphics card. Sometimes, the microphone is device 0,0, sometimes it's 1,0, and sometimes it's called "default".
Also, whenever booting into KDE, it gives some window about "forgetting" sound devices it detected last time.
Every boot, they're all there, but I think they sometimes swap positions or names.
I actually want ONLY the motherboard as sound device, and want Linux to treat the webcam as video only, and the graphics card as graphics only. And I want it to stabilize, so that I make it work in alsamixer, xmms and skype ONCE, and then it remains working forever without randomly changing.
Any ideas what I can do here? Thanks!
The wiki (https://wiki.archlinux.org/index.php/Ad … chitecture) isn't helping, it's asking to edit a file /etc/modprobe.d/alsa.conf that doesn't exist and isn't very clear about what format the name of the sound device to give should be, and the alsaconf they mention in the wiki is now disabled in arch...

You can also give your different sound devices fixed indices (fixed order). If not exists, create a file /etc/modprobe.d/alsa.conf or /etc/modprobe.d/sound.conf or whatever .conf and define the order of sound slots:
#/etc/modprobe.d/alsa.conf
options snd slots=snd-hda-intel,snd-usb-audio,...
First slot: card 0, second slot: card 1, ...
There is another handy option to give your devices neat custom names like
#/etc/modprobe.d/alsa.conf
options snd slots=snd-hda-intel,snd-usb-audio,...
options snd-hda-intel id="onboard"
options snd-usb-audio id="logitec"
Hope this helps!

Logic Mics, Aggregate Devices and The Input Issue

There is a lot of discussion about Logic's inability to accept simple microphone inputs, and I ran into this for two frustrating DAYS of trying all the things in the Logic Express 8 Docs to fix it—to no avail.
But now it is solved, so I'm trying to create a DEFINITIVE list of steps and principles here so others may quickly blast past this issue.
The equipment I have seems to be emblematic to the problem. The Blue Snowball is one of those USB mics that simply doesn't automatically show up in Logic's Preferences > Devices > Core Audio >Device list. The fix for this is never mentioned in the Logic manual or Getting Started docs that I can find. There is a passing reference on page 100 that is virtually zero help, and does not bother to mention how this Prime Gotcha can bring you to your knees.
Principle #1: Logic uses the Preferences > Devices > Core Audio >Device (list) process to identify which microphone you can record with. The list has to have in it an entry that makes sense for both the incoming audio and the playback path that Logic uses to feed earphones or an external monitor.
Normal items on that list look like this:
Built-in Output/Line Input
Built-in Output/Digital Input
Built-in Line Output/Input
Built-in Line Output/Digital Input
Built-in Digital Output/Line Input
Built-in Digital Output/Input
The Built-in Output is the computer’s inner speaker or headphones. The Built-in Line Output is the computers stereo jack for feeding to an amplifier. The Built-in Digital Output is the fiber optic feed that can also feed an amp with up to six parallel audio channels (okay, 5.1 channels).
Nothing on that list will show a fully functional USB microphone that is being viewed on the computer’s System Prefs > Sound > Input page, even though the metering dots there show that the computer sees a live, active microphone.
Selecting the Mic in the Sound prefs page does nothing to pass it on to the Logic > Preferences > Devices > Core Audio >Device list of selectable items. This is frustrating, since GarageBand sees the live mic without any problem, but GB is a simpler program that has fewer options while Logic has many other potentials, so a one-size-fits-all solution may not be its best default setting.
To get the mic into Logic, you have to go into the Audio MIDI Setup utility program where a peculiar option appears that is called “Aggregate Device”.
This keyword is not found in the Mac docs, and understanding it seems to be a big secret. Even the Audio MIDI Setup help page will show you how to find it, but not how it works or how to use it for Logic. Ahem.
You open Audio MIDI Setup and under its header bar Audio is only one item, sure enough, Open Aggregate Device Editor. That opens a window that has two sections, an upper window with Aggregate Devices / In / Out across its top, and a lower window that shows all the options that the computer is aware of. The lower window is called “Structure:” and columns show Clock / Use / Audio Device / In / Out / Resample.
A default item “Aggregate Device” shows in the top panel, and you can add others and double click on one to change its name. You can make many variations here.
By default these will be present:
Built-in Line Input
Built-in Digital Input
Built-in Output
Built-in Line Output
Built in Digital Output
At the bottom of this list any other audio input devices that are plugged into the computer should show up. If they can be seen in the System Prefs > Sound > Input page, they’ll be here, too.
When I plug my Blue Snowball USB mic into the computer, it shows up here as Blue Snowball.
You create an Aggregate Device by clicking on your sound source, in my case, the Blue Snowball, then adding one or more other options.
When you click the Use check box for any entry, it pops to the top of the list.
Principle #2: An Aggregate Device is used by Logic to “see” both an audio input and an audio output path at the same time. The Device you’re creating at this point must include an input Audio Device AND at least one Output item to be fully functional for Logic. A Help page in Audio MIDI Devices called “Combining multiple audio devices” explains this in bare bones, but you can’t see that help page unless the Audio MIDI Devices utility is open.
In my case, I’ve checked the Blue Snowball and Built-In Line Output, so I can use that combo in Logic to define where the mic is coming from and where the Logic audio output should go to my line-input amp and speakers.
In the Audio MIDI Setup utility, simply selecting the Blue Snowball as the “Default Input:” device and/or the “Properties For:” options shows that the Audio Output area of the page has this cryptic message: “Output is not supported.”
At this point, you’re almost ready to go, and you can close the Audio MIDI Setup utility. But there is at least one more “gotcha” to conquer.
Principle #3: Logic ONLY looks for its list of usable Core Audio Devices when it starts up. If you have it open right now, all the choices made for Aggregate Device will not show up as selectable. Save any work in Logic, shut it down, then boot it up again.
Now you can use Logic's Preferences > Devices > Core Audio >Device list to see your Aggregate Device. I’ve named mine “Snowy Line Out” to trigger my recognition of what it contains. Another one is called “Snowball + Line + Digital” and it has both line and digital outputs aggregated to the Snowball mic input.
You can make one in the Aggregate Device Editor that combines a microphone plus earphones (Built-in Output) plus Line and/or Digital Outs, too. You'll have to switch among them in Logic as you work, but each will carry the live mic direct to recording.
I hope this gets you through the frustration of not knowing what to do when confronted with the lack of clear docs and complete steps to get a USB mic or other seemingly opaque input issue. Feel free to add to this so others in my former state of bewilderment can gain understandings.
If Steve Jobs were to encounter the level of opacity, ambiguousness and frustration that setting up a simple USB microphone can create in Logic, you can bet that the several programs and their intimate interdependency would be either automated or fully explained in the documentations that followed his fiery analysis of the issue.

I don't know of another way to get the Blue Snowball USB mic to show up in Logic. If you can do it without having to go through the Aggregate Device route, feel free to post here how to get that to happen.
I didn't have a different mic available when I started trying to do what seemed to be the simplest of things -- record and play back an audio track -- and nothing else seemed to work.
There are a lot of Aggregate Device threads around here, many associated with Blue Snowball, Blue Snowflake and other things, but none of them laid out the principles of how Aggregate Device Setup needs to work or what to do to force it into compliance.
As I said, the clues in the Logic docs and in-mac docs are minimalist, at best, none of them bringing instant head slaps of success readily.

We just added a new printer and bluetooth connection to our iMac. Now iTunes does not recognize our iPads as devices. Have already tried restarting everything. Any other suggestions?

Does anyone know why this is happening and how to rectify the situation as I have tried every help setting for the last 4 hours.

I have tried everything I have read on the Internet about sync issues and restore etc and not there isn't a single song on my iPad or iPod touch. All of the songs are listed in my iTunes but are all greyed out, some have the cloud symbol next to them but lots don't and some say waiting.
Long and short is nothing will save to my devices at all.....HELP !!!!!!!?

I'm getting no sound with firefox 4, it's outputting to the wrong audio device and I can't find a way to fix it in options

Since I've updated to firefox 4 the program has decided that it wants to output it's sound to any driver it pleases instead of outputting to the playback device I have set up as my default device. the only way I can get it to output correctly is to shut off every other device besides the one I want used. I have a 5.1 surround sound system and a 7.1 surround sound headset I use with my computer and would like to deside what output I want to use for my internet browser instead of it deciding it wants to use an output I don't have anything hooked up to.

First you have to buy and install 10.6 Snow Leopard:

No sound device...and problems to shut down...

a friend of mine kicked by mistake my Mac and after that I lost the sound device...even though it runs sometimes...it got character I guess...
and it also doesn't shut down sometimes and freezes...so I have to turn it off taking out the battery...
that's the solution I found...but I might have a problem...
can some one help me?
what is best to do?
Thanks
Shantiimac

Did all these problems start with the trauma to the iBook from your friend's foot, or were they already there to some degree? Especially the freezing? If you were already having problems, the accidental kick may have just served to make them worse.
There are some general things that you could try. You could find the set of CD's that originally came with your iBook and find and run the Apple Hardware Test and see if anything comes up in the form of an error code. You could try resetting the PMU. You could go to Disk Utility and verify both permissions and the disk and repair if necessary. You could check and see how much free space remains on your hard drive.
Freezing could be software or hardware related. Because of the trauma to your machine, it may well be hardware. Nevertheless, it is well to do a little hard drive maintenance and software troubleshooting just to be sure that software is not a factor here.
Please post back with how it went with the AHT and DU and resetting the PMU.
Also, you can apply pressure to the lower left side of your iBook and see if this makes any difference.
Good luck!
