USB Audio not listed
Before I installed Leopard under SYSTEM PREFERENCES>SOUND>OUTPUT "USB Audio" was listed. Now it no longer appears. How do I get it back on the list? Thanks for any help you can give me.

I have tried every angle listed above, and at the moment, will record in Audacity, export AIFFs and use those in PPCC.
I recently went through this grind with a new Rode Podcaster USB mic on my Mac. It actually took allowing the Adobe support folks to grab control of my screen and work through figuring it out, though now that I look back on it: some of that may not have been necessary. But, that aside, here's what they did:
Ran the Audio MIDI Setup application (built-in to OS X) and created a new "Aggregate Device". In said device, they put the Podcaster as the input.
I then added the Line-Out as the Aggregate Device's output so that Pr could play sounds properly.
In Pr, set the Audio Hardware to that Aggregate Device.
Create the mono track as explained above, and click the "R" in it. If the "R" stays depressed, you're good to go.
The problem I was having was that I'd chosen the Podcaster as my Audio Hardware in Pr, but didn't remember to add the mono track. I didn't need to do that with my previous USB mic (Blue Yeti). So when I clicked on the "R" in the audio mixer window, it would just bounce instead of staying depressed. Creating the Agg device and the mono track seemed to fix that.
However: I'm not sure the Agg device is necessary. I've since experimented a bit more with Pr and OS X and everything is working properly without the Agg. In the OS X Sound preference panel, I made sure the input device was, indeed, the Podcaster with the output being my Line-Out port. Within Pr, I set the Audio Hardware to the "System Line-In/Line-Out" choice. From there, as long as I have a mono track set up properly, I can press the "R" button and go to town.

Hello All! I have a late 2012 MacBook Pro with Retina display and a powered speaker system that connects with USB. Now I have a late 2009 MacBook Pro that these work just fine with. Both Computers are running Mavericks with all the latest updates. Using them with the 2009 Pro I get the option for "USB audio DAC" under the sound settings in System Prefs, but nothing on the late 2012 Pro. I really need to fix this so any help would be awesome! Thanks!
Problem Solved!
It turned out to be a combination of the usb cable and the OTG USB hub. On my desktop the iBaso was cable specific as to the device being recognized. When I tried the working cable witht the OTG hub on the Stream 7 it failed as usual. But when I tried the cheap monoprice adapter it worked.
The usb audio solves the horrible sound problem with the Stream 7 for anybody who is lookiing for a Fix.
The OTG hub works with a mouse and a mSata drive perfectly but not with the iBAso DAC.
Thanks to everyone who replied for keeping me trying. -
TS1538 apple mobile device USB driver not listed in Windows 7
Installed iTunes on my son's HP laptop, but when he plugs in his iPhone 4 it is not recognized in iTunes. I've done the following:
* Rebooted the computer.
* Tried multiple USB ports. The cable is good because the device can charge without any problems.
* Restarted the Apple Mobile Device service.
* Uninstalled/reinstalled iTunes and all other Apple software.
* Verified that there are no Apple related devices listed anywhere in Device Manager.
* Been through all of the troubleshooting steps at this site: http://support.apple.com/kb/TS1538
His iPhone is currently on a version less than 5.0. iTunes is whatever is currently available from iTunes.com.
I'm stumped. I'd love to hear some other idea. I appreciate any and all help.PhotoWes wrote:

That's not really helpful.
What specific version of iOS is on the device and more importantly, what version of iTunes?
Just because someone believes they are running the current version does not make it so. -
Macbook not (completely) detecting USB audio device
Here's what I'm doing. I am ripping my cassette collection using a tape deck, a Roxio video capture device (VHS to DVD), Soundflower, and Adobe Audition. Everything was working fine. I finished a tape and unplugged the USB device to make room for my headphones so I could check the file I created. After doing this, OS X stopped detecting the USB device. Here's what I can tell you:
It no longer appears as an input device under System Preferences > Sound.
If I fire up the Easy VHS to DVD Capture software it's clear the software is getting audio (the faux LED meters are responding to the audio coming from the tape deck) - just can't hear anything!
Adobe Audition was listing the device as "USB 2861 (Not Working)" right after this issue. As soon as I changed the input in Audition, this entry completely disappeared. (For those unfamiliar with audio applications, it's simply looking at the inputs set up in the OS.)
Under About This Mac > More Info > System Report > USB, I see the USB 2861 device.
I'm at a loss. So you can see that in some way the device is being detected, but the OS doesn't see it, which means I'm effectively dead in the water. I've tried a number of things; rebooting, an SMC reset (I think that's what it was called), physically removing and reconnecting the device both the while the machine was on/off/after reboot.Problem Solved!

Windows 7 x64 USB AUDIO DEVICE - Device Not Working - Mac Pro
I have a mac pro early 2009. I had vista x64 installed, everything was great. I had 2 audio devices under device manager, one was listed as HD (digital) and one device was listed as analog audio.
When I played games and wanted the external speakers (using the digital out connection) I had the HD (digital) audio device enabled.
When I played games and wanted to use a headphone/microphone combo, I had the analog audio device enabled.
Switching between the two was as easy as clicking the audio device icon and clicking on whichever device I wanted.
Now that I installed windows 7 x64, I have a HD (optical out) device in device manager and it works perfectly. Unfortunately, I also have another device listed called "USB Audio Device" and it shows a yellow exclamation mark next to it and it is NOT working properly.
I tried many suggestions on here, which included downloading the cirrus logic audio driver and picking different models, as well as trying the snow leopard install disk driver for cirrus logic, and even tried installing the realtek analog driver. The closest I got to getting anything to work was installing the realtek analog driver. It installed fine up to the point when windows said "this driver is not tested, do you wish to install it anyway?" and I click yes, but then it pauses for a few seconds and the same message comes up again and repeats in a endless loop until you say "no, do not install driver" and then it does a uninstall of the driver.
Has anyone else experienced this problem and if so were you able to fix it?
Thanks

Realtek High Definition Audio for Vista\Win 7 2.54
2010-11-05
Realtek HD Audio Windows 7
Or from Realtek which is http://218.210.127.131/
http://www.realtek-driver.com/
Guru3D is also a popular site for drivers.
http://downloads.guru3d.com/Realtek-HD-Audio-2.51_d2598.html
You can ignore USB audio, you want RealTek HD Audio. There are or can be some of those yellow alerts that are safe to ignore. Buried somewhere in Apple Support BootCamp technotes.
You can use installer from Realtek or zip file in which case just uncompress and update the driver from inside Device Manager. Nice thing, you can rollback a driver if you want to, or totally uninstall and then reinstall. -
Hwd -e does not list connected USB devices
USB devices for audio in/out not recognized in hwd -e.
Desired USB Items appear in KDE INFO CENTER: SOUND.
KDE MIXER alternate...USB Mixer... shows OUTPUT PCM icon but no INPUT device is shown (thus, no device is connected).
System has udev installed but uncertain whether root permission is provided for the USB devices...namely...USB MIXER and SND-USB.
Spent many hours in stupid search for ...audio group....and ...optical group...
when the reference name for the "group" is...audio devices... and ....optical devices... This is a common problem in searching out posts..improper nomenclature references.
A listing for ...mixer...is provided but none for ...usb mixer...
Can I assume that all entries in the udev permissions file permit immediate use by root? Do they have to be edited to function? The indications are that root owns them all and doesn't need permission.
Sure would like to get USB audio running!!!
Are there special requirements for the USB devices?Additional info:
Tried playing a CD track copied onto the desktop in XMMS. The display shows it responding in XMMS. There is no audio from the external USB sound device.
The mixer in KDe is set to USB Audio mixer (PCM). An output ICON appears but there is no INPUT icon( No source connected).

my mini mac recognizes my usb mic, but premier pro does not list it under preferences?
Hi Robert,
This has to do with Audio MIDI setup. See this article: https://multimedia.nscad.ns.ca/pdfs/Setting%20up%20a%20USB%20Microphone%20for%20Premiere%2 0CS6.pdf
I hope it helps!

M-Audio Micro USB soundcard not working
I've recently got this audio card bundled with an M-Audio Keystudio 49.
It works flawlessly on Windows but on Linux it doesn't. I don't have any other things to try, I've tried configuring an /etc/modprobe.d/alsa.conf but it doesn't work. The snd-usb-audio module is loaded. Can anyone help me?

USB Audio Device sometimes not detected. udev, maybe?
I am using an external usb audio device which I usually keep plugged into my machine. I am finding that this device is sometimes not being detected when I boot the computer.
When this happens, issuing the following command:
$ aplay -L
does not list this particular device. Plugging and unplugging the device does not seem to help.
What does seem to resolve the problem is unloading and then reloading the snd_sub_audio kernel module. This is done by issuing the following commands:
# rmmod snd_usb_audio
# modprobe snd_usb_audio
Could anyone give some insight as to why the usb audio device isn't being detected and why this only happen occasionally? Could this be a udev issue? The device in question is an M-Audio Fast Track Pro.Make a "Genius" appointment at an Apple Store.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

USB audio input to voice-over tool not working

im sure its something simple im overlooking??

USB-Audio does not work correct on T430/T530
Hi all!
I'm owner of a T430 and a T530. Both are new PCs where I have installed Windows XP. The reason for XP is that I own older software and hardware, which is not supported on Windows 7. But it works fine and I have no reason to change hard- and software as long it fulfills my requirements! And Windows XP runs fine and fast on the T430 and T530.
Only problem is an EgoSys USB Audio interdace U2A. It is possible to install and run it, but there is a problem in the communication between operating panel and the hardware. When I move the slider for the level, the level jumps instead a smooth increase of the level, which means not alle values of the slider are transferred to the hardware. There is a similar behaviour with checkboxes: there are states of the U2A which are indicaed with LEDs. When I change the checkbox, sometimes the LED changes, sometimes not. This errors happen very frequently but not reproducable.
I tried several settings in the BIOS, like disabling one CPU, hyperthreading, USB3 etc. I tried the U2a also on a fresh XP-intallation without other software, but all without success, the behaviour of the U2A is always the same!
I also tested with an ExpressCard with USB-port from LogiLink, but this card does not recognize the U2A at all.
Up to now I have used the U2A on many different PCs without problems. What might be the reason that it does not work on an ThinkPad? Up to now I was very satified with the U2A and I would not like to replace it!
regards
GKapHello faith67baillie,
Welcome to the HP Forums!
I understand there is no sound from CDs or your Music folder. I will do my best to help! First, I require the following information, and clarification of the issue:
1. The computer's model number. If you require assistance locating this information, please reference this website: Guide to finding your product number
2. The computer's operating system. If you require assistance locating this information, please reference this website to determine your Windows operating system.
Additionally, if the issue just began occurring, I would perform a system restore. I want you to bring the computer back to the earliest restore point possible, in an attempt to dodge whatever caused the issue. Here is a document on how to perform a System Restore: System Restore

TS1538 What do I do after step 6 in "If the Apple Mobile Device USB Driver is not listed"?
i'm very confused about step 5, "Verify that the Apple Mobile Device USB Driver is installed" > "If the Apple Mobile Device USB Driver is not listed", what do I do after step 6? I looked for and found the entry that recognizes the device as a camera, "Apple iPhone, now what? I'm trying to resolve an issue. After an iTunes upgrade in July 2012, I have not been able to get my iTunes to recognize any of my devices. I have uninstalled/reinstalled iTunes, all the steps. Now I'm on this one and I don't know what to do after this step 6. I looked and found the entry.... now what??? I am out of room on my phone because everything I buy on iTunes on the computer mysteriously appears on my iPhone 4, and everything I buy on my iPhone mysteriously uploads onto my iTunes the next time I open it. My phone will charge when connected to the computer, and Windows recognizes it and asks how I want to open pictures, etc. But in iTunes it will not show up under Devices. This is getting beyond ridiculous and I have to get some of this music off of my phone!
Found a possible solution for me.
While the phone was plugged into my computer and iTunes is CLOSED.
1. I went to Services in Windows.
2. I selected Apple Mobile Device and right clicked and selected "Stop".
3. Then I right-clicked again and selected "Start".
4. Then I went to Device Manager and right clicked my iPhone with the yellow alert icon and selected "Uninstall". You will get a warning about uninstalling the device. Click OK.
5. At the top of Device Manager I clicked the Action menu and selected "Scan for Hardware Changes".
This re-installed the iPhone and everything started working again. -
USB Audio Device Not Recognized by Stream 7 tablet
Half the reason I bought the Stream 7 was to use it has a music player with my iBaso D2 USB Audio DAC Headdphone Amp.
The device is recognnized by my Win 8.1 desktop and every other computer I've plugged it into. Why it is not recognized as an audio playback device is beyond me. I've tried all of the suggestions that I've been able to find on the net without any luck. Is therte some reason why this function has been disabled on the Strwea 7?
This question was solved.
View Solution.Problem Solved!
It turned out to be a combination of the usb cable and the OTG USB hub. On my desktop the iBaso was cable specific as to the device being recognized. When I tried the working cable witht the OTG hub on the Stream 7 it failed as usual. But when I tried the cheap monoprice adapter it worked.
The usb audio solves the horrible sound problem with the Stream 7 for anybody who is lookiing for a Fix.
The OTG hub works with a mouse and a mSata drive perfectly but not with the iBAso DAC.
Thanks to everyone who replied for keeping me trying. -
