Two Thunderbolt Displaysand USB Audio Issue

I have a brand spanking new Macbook Pro 15" Retina (2.7 Ghz, 16GB RAM, discrete graphics chip). I also have two thunderbolt displays, one is about a year and a half old, the other is pretty new.
I also use an Apogee Duet 2 USB sound card.
If I plug the USB soundcard into my Thunderbolt USB, after a few minutes the audio is all distorted. I've so far resorted to using a USB port on the MBP itself, which fixes the issue.
Is there a "Best practices" guide for how to connect up these displays? I currently have them daisy chained, so I have just the two cables going into my Mac which I wanted. Is there a better way to hook this up for reliability sake?

I have this exact same issue. I wish there was a fix but I have been looking for a while. Apple must know about it!

Serious Usb Audio issues after attempted fix.

I have serious macbook usb audio issues, some help?
So recently I've been trying to get rid of my the robotic sound my macbook makes with usb audio using this tutorial:

Z77MA G-45 Usb audio issues.

I recently purchased an MSI Z77MA G-45 motherboard for recording music. I have ran into issues from the start. The usb ports appear to be causing crackling and popping whenever I plug in my M-audio fast track Usb or my Focusrite Saffire 2i2. I have the latest drivers for everything installed. I have the latest bios v1.8. Every other bsb device seems to perform fine. I have both of these usb audio devices working properly on my older core 2 duo setup with no problems. My power supply is in fine working condition and the voltage does not fluctuate when these devices are running. I have tried disabling HPET, Turbo Boost Etc, with no luck.
I began to think that it was the motherboard so I sent it in for RMA twice. The first time it was "repaired" it was sent to me unable to boot. The second time it was sent back it still ceases to function with these devices. The other computer components are fine. I believe the usb ports are defective. Does anyone have any advice? I would rather have a new motherboard returned if I have to RMA it again, or would prefer a refund. I have only had it about three months. It unfortunately passed the refund time with the original company I bought it from.

Ah ok, try updating to the most recent beta bios:
>>Beta BIOSes<<
>>Use the MSI HQ Forum USB flasher<<
Download the latest file to your desktop but don't decompress.
Then use option 1 of the flash tool and let the tool prepare you flash drive for flashing.
Then boot to the flash drive and follow the on screen direction.
Once complete you will need to re-install the ME drivers from Intel Downloads:

USB Audio issues - Philips SpeechMike - Fusion v3.1.2 on 10.6.6

Hello all.
Sorry, I know this is a cross-post on the VMware Fusion forums too... but the issue seems to be Apple related based on the 10.6.3 bugfix.
I am at a loss here and hope someone has a few pointers.
We use the Philips speechmike devices for dictation in windows via dragon. Previously we were running XP pro sp3 but are now installing Win7 pro. As part of this, we have upgraded to 10.6.6 and our fusion to v3.1.2.
Since this point, our speechmikes are not working properly under either the XP or Win7 machines.
Once the device is attached, whatever we do first (playback or record) is what the device will do. For example, if we plug it in and the 'ta-da' audio plays for a new USB device, the speechmike will only play audio and the mic will not work. If we disable playback by muting the audio output, disconnect and reconnect the speechmike, we can now record but attempts to unmute and playback audio throw errors.
This behavior is very similar to that of an IRQ conflict with the USB device...
I know about the USB problem that existed from 10.6.0 - 10.6.3, but the scratchyness in the playback audio is lightyears better than this.
FYI... We can't use the audio device under Mac OS since the control buttons on the speechmike will not translate through to the Windows OS. These are a requirement.
Help please!
Thanks in advance. -Peter.
Macbook Pro 2.66GHz Core i7

+ Fusion v3.1.2

Two widgets, One slide- audio issues

Hello,
I am currently working on a project and have two widgets on one slide, that will play audio when a user clicks on the individual labels:
When I preview, the widget on the right will not play any audio (the left does). I have tried everything: refreshing, deleting/adding back audio, duplicating the slide, making sure the widgets don't touch, etc and it still won't work. Has anyone had this issue or am I not supposed to use two widgets on a slide?
Any help is appreciated!
Thanks,
Jasmine

Hi,
Thanks for the reply! I am in 7.0.1 and I double checked and absolutely nothing is overlapping on the widgets--not even the placeholder box. I even tried to make sure that it wasn't b/c the first widget wasn't overlapping on the timeline, but that wasn't the case.
I should be able to have both widgets up at the same exact time, playing audio when clicked on, correct?
Here is my timeline, if that helps any:
Thanks again for the help!

Thunderbolt to HDMI audio issues

I apologize in advance if this has already been asked in some way that I didn't see in my previous searches for answers.
Why is it telling me this? I have been pushing audio through perfectly fine, then yesterday it started to display this and was no longer pushing anything. Anyone know how to fix? I have changed nothing on my physical display or my prferences to bring about this change.

I posted a picture on there, but it appears it didn't go through. I shall attempt to get it up again.

Are USB audio interface issues on iMac Haswell resolved?

HI,
i just ordered a 27 inch iMac, maxed out with a 1TB SSD.
I noticed the imac doesn't have an audio in jack and figured i'd shop for a good USB Audio Interface.
But then i came across all these USB audio interface issues on the new iMac.
This is incredible to me because iMacs are often used by creative people and lots of musicians.
For me audio is VERY important. I record music and i record sound for animation and video.
Apple thus far seemed to be avoiding the topics and issues at hand.
Are the USB audio issues resolved? What was resolved? What was the problem (Maverick? Fusion Drive)?
Is it wise to choose for a Thunderbolt Interface? Which one?
Any help would be hugely appreciated.
Especcialy since it seems such a wide spread problem.
Thanx

doubt it would be a general issue
usb is a universal serial bus it always require a driver for anything
and the driver of one external audio device would act different then the driver from another external audio device
so it would be very unlikely that an external audio card using a cirrus logic audio chip would cause the same issues with the imac as one with a realtek or soundblaster audio chip
not that there could not be issues with all of them but not likely that they would suffer from the same issue

Two thunderbolt displays.....can I use both of them for audio

I have two thunderbolt displays and want to run audio through both of their built in speakers? Is this possible

Yup yup -- but there's issues..

Audio stutters when under CPU load, USB sound issue?

ACD 27" connected to a PC via displayport/mini displayport adapter. When playing music while doing CPU intensive tasks, the audio instantly stutters, cuts out, grumbles, etc. This suggest my PC is simply not powerful enough however that's not the case (specs below).
What i've determined.
1. This only happens when using the apple display for audio.
2. When speakers/headphones are plugged in to the motherboard, everything works great.
3. This happens with all audio applications. itunes, vlc, winamp, etc.
The display uses its built in USB cable for audio, right? I'm thinking it's gotta be some typ of driver issue for USB audio. However I've updated all drivers so I'm stumped there.
Specs:
Intel Core i5-2500K @ 4.6GHz (65-70* under load)
CORSAIR CWCH60 Hydro Series H60 High Performance Liquid CPU Cooler
GIGABYTE GA-Z68MA-D2H-B3
G.SKILL Ripjaws X Series 16GB (4 x 4GB) DDR3 1600
Kingston HyperX SH100S3B/120G 2.5" 120GB SATA III SSD
SAPPHIRE 100326L Radeon HD 6670 1GB 128-bit GDDR5
Apple 27" LED Cinema Display (via displayport)

Unable to combine two distinct USB Audio devices into one Aggregate Device

I'm trying to use Audio MIDI Setup to combing two separate USB audio speaker systems into "one" so that iTunes will play through both simultaneously.
I can create the "Aggregate Device" and add the two USB devices but I can't get the two checkboxes to remain selected after I "Apply" changes when setting them up in "stereo". If I set them to Multichannel quadraphonic then I can select both devices but only one of them will play sound...I assume because iTunes doesn't output in Quadraphonic.
I've searched these forums and the Interwebs and hear of people having success (and difficulties). Difficulties mostly because of the misunderstanding of what a "device" is. These are both EXTERNAL USB devices. One is SoundSticks and the other is a USB audio converter that passes analog into an amp.
Why is this so difficult? Oh, I know...because  wants to sell you $80 Airport Express to stream music wirelessly to devices that are literally ON THE SAME DESK!
Anyone have success (or confirm more failures) with what should be a trivial exercise...

The idea with the Aggregate Device is to allow several audio devices to behave as though they are one multi-port device with discrete one to one I/O mapping. It is not intended for one stereo source to feed more than 2 channels of output.
However...
Set up your aggregate devices as 4 audio outputs, install Jack (http://jackaudio.org/) and use that as a virtual router with qjackctl.

L305SD-S5874 Audio recording issues to USB Audio Interface

I am hearing snaps and pops recording audio through a USB audio interface attached to my laptop.I am using an external Hard Disk connected to a card buss e sata interface. Audio plays fine but snaps and pops are heard when
recording or even when an input channel is selected but idle.I have the latest drivers installed.People in other forums are saying that these problems are due to my using a " cheap" laptop with poor IRQ sharing implementation in the chipset.Is anyone using a similar computer this way with no problems ? I have recorded audio for years to much less powered computers with good results.

Sounds like you're listening to the same source (the X6) being played twice.
Could be you are hearing MIDI thru playback as well as Logic's "Software Monitoring" you must also be enabling a MIDI track for recording. If you unhook the MIDI connection from the X6 does the hollow sound go away.
What Audio interface are you using? The other possibility is your Audio Interface has "Direct Monitoring" this allows you to monitor the audio inputs before it goes into the computer. Having Logic's Software Monitoring enable along with Direct Monitoring would also produce the hollow sound.
I suggest the thorough reading of the manual so you understand what all the preferences do. Most of the time it is better to read and understand/experiment on your own. It's one thing to be shown something another to figure it out for yourself.
Here's a Link to all of the Preferences/Audio settings.

External USB Audio cards major issue

HI,
I bought 2 USB audio cards to test, one the Tascam US-122L via usb2.0 and another one the audiobox USB, (usb2.0) (latest driver installed too) Both on 2 HP laptop, one on DV5-1225ca (latest bios) and hp TX1218 when playing MP3 or any music software tools, static sound and stutters, this is with Vista 32 bit SP1. First I bought the tascam then return it, I tought it was the cards, but I bought a new one and the same problem even on 2 different laptop!
Best
Chris

hi i just like to say i had a similar fault though i would be surprised if it causing yours,but you never know,my fault was my laptop lid, [9 months old] it contains the mic ,and when the lid was in a certain angle crackles could be heard worse when i had my external sound card in, it was a faulty membrane [ lid to body] easily missed by engineer because it was the same angle all the time it happened,good luck, PS you English is very good

Problem with two thunderbolt display's daisychained

hey,
i'm having problems with my mac setup. i've got two thunderbolt displays, hooked to a 15" mbp retina laptop.
i've got my iphone hooked to one of the usb ports of the display then i've got a keyboard, a superdrive and a charger for my magic mouse hooked to the displays as well as a firewire hd. two usb 3 hard drives are hooked directly to the mbp.
i also changed the audio midi setup to let the audio pla through both of the displays to get a better sound. the mbp is closed so only those two displays get a video signal.
i have issues when data is transfered along the lines. f.eg my keyboard doesn't work from time to time, my iphone wont be recognized when connected to the dock. not really sure what the problems is a the transfercapacity shouldn't be to it's limit.
could it be a energy problem? that the displays don't get enough power, my power strip has a voltag controller in it, might that be a problem?
greets.

I think Apple should extend the warranty if they have a known manufacturing issue. I won't be investing another $1000 on a display from Apple ever again. I can't afford it. I can by an LG, Viewsonic, Dell, or "fill in the blank" for a fraction of the cost.
I expect a $1000 display to last me more than 20 months.

Bootcamp 3.1 and imac windows 7 64bit update not installing. Audio issues!

After many days of work getting the windows 7 working in bootcamp in my imac 27 (still with audio issues) I eagerly awaited the bootcamp update and imac updates.
Neither will install.
Then I find that according to tech support as of now I have to reinstall Windows 7 again for the updates to work!
It took me 5 full 8 hours days to get all my scientific programs installed and working, now I find I can't even simply update the drivers I need. I don't want to reinstall.
My only issues are audio.
Here they are:
1) The headset jack works fine on the Mac side, but in Windows 7, it causes the i7 intel CPU to go crazy. There is no CPU spike on the mac side.
2) The headset jack in the imac is a trrs jack. The same as in the iphone, a tri-band jack that has three bands, two audio out channels and one mic in channel. A trrs headset works fine on the mac side with using the headset mic (as in iphone) rather than the built in mic. (this provides much better quality for sound recording). I don't want to use a usb mike.
In Windows 7 the mic part of the trrs headset does not work.
3) In Windows 7 when going into audio devices recording, no audio mixer shows up, so when I do video or audio screen capture the only way to capture the sound is through the speakers and then back through the imac built in mic, rather than directly through the unit. (terrible sound quality) On the mac side the mixer element works fine.
Now I find from other imac users that even the new updates for the imac on windows 7 don't address and fix the audio issues. I am sure not going to go through 5 more days work only to find the audio issues still don't work.
I need these audio aspects to work properly though!
I have tried to get drivers for the cirrus logic audio card, but guess what there are none available and cirrus logic doesn't even recognize the board or offer drivers.
I have many windows programs I must have for my scientific research!I bought the top of the line Imac with all the bells and whistles because Apple promised that the machine could run Windows 7 in bootcamp natively!
It doesn't. This has been a nightmare of problems.
Is Apple going to step up to the plate and make good on their promises?
Does any one have a fix for any of the audio issues, or know how to install the new drivers without a complete reinstall of Windows?
Installing a few sound drivers and software should not require a complete reinstall. Getting the proper drivers for the headset jack audio in and audio out jack should be the most basic of fixes. Making the audio mixer work should be elementary.
If you are an Apple tech person or an Apple user that can help on these issues, please do!
Thanks, Dr. Duke

PS I will post this under Imac windows 7 updates without a reinstall and under
imac Sound issues.

On another thread a few people have responded saying that their imac has the same situation, the cpu is going crazy and the imac gets hot with headphones or speakers plugged in. But this doesn't happen in the mac side.
If you have an late 2009 imac and don't have these audio issues, let us hear from you. If you don't, lay out the problem here.
Here is my last two cents in to the inquiry.
Not only does the cpu run crazy but the imac 27 gets very, very hot. Since I unplugged the headphones, it runs much, much cooler.
Certainly, some Mac engineers should take care of this problem, it seems it is universal on all the imac 27's and from what I gather, the smaller screened cousins too.
Also, we certainly want a stereo mix option for audio in or out, or what is called "what you hear" or wave out. Imac is supposed to be much geared to multimedia apps.
Finally, the mic jack part of the trrs set up MUST be fixed! A lot of manufacturers are going to headset combo jacks as they call them, mic in and stereo out on the same tribanded plug. But, the old single jack for mic in and single jack for stereo out are two tiny parts of the hardware and super inexpensive for the manufacturer. Why in the **** to go to the "advanced" triplug if the **** thing doesn't work.
Mac has a great reputation. I hope they remedy these problems right away.
Anyone whose imac 27 or 24 whose headset plug is working correctly. Let us know! I don't think anyone's is, but I think that few people understand that their cpu is running so much faster with the plug in, plus few even understand the combo jack and the triband, or trrs audio jack! Out of 4 audio technicians I talked to, not one of them knew what a trrs jack was or that you even have a mic in jack as part of the headset jack!
When I told one senior that it worked on the Mac side, he didn't believe for a while, thought my sound might be recorded from the onboard mic, but I proved it to him by tapping iaudibly on my iphone mic headset and and it showing up in garage band clearly and listening to big difference in audio.
As for a usb audio adapter, I am in a neon light environment and find that those adapters are more sensitive to electrical interference. Besides I want to use the headset jack as it was meant to be used!
Thats it.
Again, if anyone using an imac 27 and windows 7 64 or 32 doesnt have these problems, let us know! We are all anxious for a fix!
Best to all!
