Frequent dropouts/clicks with USB Audio Interface

I am using a Toneport UX2 Audio interface (USB) that worked flawlessly with my PM G5. Now on my macbok pro, I get random, about every minute or so, droupouts or clicks in audio. It happens in any audio on the machine. Played in any software, itunes, dvd player, internet sources, etc. Its the same stutter on each source. Line6 support, as well as some other internet forums blame this on the USB chipset of the 15 inch MBP. They say that the data transfer rate is inconsistent and as a result i hear the click when the transfer rate drops. This is something that wouldnt be noticed in a printer or other USB device because its not dependent on a steady stream of data. But I hear the frustrating click in all its glory on every audio source. Both USB ports are effected. The Toneport is connected direct into the MBP (no hub). All the latest drivers/updates are installed. Please someone help me!!! Thanks...

I have a similar discussion in because of my audio interface, I have called Apple about it. Check the discussion here:

Constant clicking/popping with USB audio interface (scarlett 2i1)

Hi, I'm having a very frustrating issue with my audio. for the time being I have just decided not to use any audio (which is absurd). I have had this problem with Arch, Mint, Ubuntu, Fedora, etc...
My audio interface is a Focusrite Scarlett 2i2, and I cannot get it to stop making popping noises. Initially, it would only do it when I would open an application (regardless of whether that application relies on audio), move back and forward in my browser, etc. Anything that makes the computer work. Right now, it is popping every 1/2 second, probably because dd is cloning a hd right now. Possibly related, qjackctl has started saying it can't connect to JACK server, I'm pretty sure it worked when I first installed it (it tells me "ALSA: cannot open PCM device alsa_pcm for playback.
I have tried the following:
-ediitng asound.conf with various suggestions online for others that have had this issue - changing sample rates etc... unfortunately none of them are using the same interface so I don't think they apply to me. I don't really know what most of the things in these files mean, otherwise I would probably be able to configure it properly.
-blacklisting every other sound card in my computer
-adding a .asoundrc file as suggested here:
-tried to view information on my sound card with lsusb -v, but I don't know how to pinpoint the sound card so the list is too long for me to scroll all the way to the top (I typically have 12 to 14 usb devices plugged into this computer)
I mainly use OS X, but I would like to use Linux for music production as well; obviously this has made it impossible. Again, this has happened with every distro I have tried.
Please help, this has basically made Linux unusable for anything other than very basic internet browsing. I'm using gnome-shell and linux-rt kernel.

Problems with USB Audio Interface

My Behringer mixing board came with a USB Interface so I can out put the audio from the board into my laptop via USB. The trick is though Logic recognizes it and I can record say microphone audio from the board on Logic, I cannot hear the tracks that already on Logic. For instance, say I want to record a vocal track onto something I have created on Logic. Logic will let me record the microphone vocal but it won't allow me to hear the track, rendering it useless. It is a very simple USB interface and I have been thinking of upgrading but I am wondering if it something I am doing wrong on Logic. Any thoughts?
Ken

when you select , lets say the USB device in your audio preferences, it will be used as the input and output device. You can use the USB interface's audio outs plugged into your mixer, and use speakers or the headphone jack. When you create an aggregate device, using the USB device and your built in audio, and choose it in your audio preferences, this allows you to use the inputs and outputs of both the USB interface and your built in audio from your mac. So now you can record from one device while listening back on another. meaning you can record the audio from the USB device and listen back using your Mac speakers or from headphones plugged into your mac.
if you get a better audio interface, one with mic inputs, you will still need to connect it to speakers or plug in headphones to it to hear audio. If you have the budget, a dedicated firewire audio interface will usually give better results, in audio quality, than a behringer mixer and a usb interface.

Can't hear playback with USB audio interface plugged in

I start Logic Pro 8 and then plug in Lexicon Lambda for a USB interface between guitar and macbook pro. With the Lambda plugged in I hear nothing from mac or headphone input on Lambda. If I unplug Lambda I can hear playback from mac just fine thru speakers or headphones.
Very appreciative of any advice on how to solve this.
Thanks.

Unplug your audio interface, reboot the Mac, plug the USB interface in, let it be recognized. Open Audio/MIDI Setup (in utilities) see if the Lambda shows up as an input and output device.
Yes/No?
If yes, you don't have to select if for any of the Input/Outputs, Logic's audio interface selection operates independently from the system.
Open Logic go to "Preferences/Audio) select the Lexicon or Lambda interface as the default unit, set audio buffers to 256.
Anything yet.
All audio I/O will be coming from the lexicon the Mac's audio system is now out of the equation.

Help with Usb Audio interface

Hey guys, just having major issues setting up my recording software to work in boot camp my usb audiophile seems to be connecting and functioning with Windows 7 but the audio quality is really poor with distortion, i have seen that this is a regular problem and would much appreciate a solution or a link to one that would be a great help
my set up is a imac running 0s x version 10.6.8 with boot camp running windows 7 32 bit the Usb interface is the M-audio Audiophile
Thanks

GT Player Express is a real-time standalone application allowing to use your computer at studio or on the stage as powerful guitar multi effect processor. It offers ReWire support, for connecting to ReWire applications such as Live or Reason. Track Recording support allows recording of the processed or clean sound. Recorded tracks are automatically added to the current playlist. GT Player is functional as a VST plug-in which can be used in all VST host applications such as Nuendo, Cubase, Live, DSP Quattro, Spark, etc. With Keyboard Transpose, MIDI notes can be triggered from your computer keyboard with transpose capability.
According what I read, this app is VST only, so it won't work with GB, sorry. GB uses AU (Audio Units) and not VST.

Live Capture with a camera via firewire and usb audio interface

I am trying to do a live capture through Final Cut 7.
I want the video feed through the firewire from my HVX200 and the audio feed from a 4 channel usb audio interface (Alesis iO4).
When I have both audio and video input coming in from the HVX200, the live capture works fine.
However, when I change the audio input so that it is coming from the usb audio interface, final cut has an error message saying "Video is not available."
During the preview, I see the video clearly and am getting levels from the iO4.
But when I try to capture, I get the error message.
Is it a processor issue (I've attached my specs below) with problems handling 2 separate inputs?
I'm not quite sure what the problem is.
Any input is greatly appreciated.
Thanks!
Model Name:          MacBook Pro

Hi MtD,
Yes I am changing the Capture preset to iO4. Once that happens, it lets me run both the camera and the iO4 into the laptop but then an error message pops up the moment I try to capture it.
I was only trying to use 3 out of the 4 channels of the iO4.
Thanks!

USB Audio Interface with bad latency problems under bootcamp

Hi everyone,
I am currently running an Edirol UA-25 USB audio interface under Mac OS X for my normal music-listening needs. Everything works fine, and there is next to no latency when messing around in Garageband .
However, when I switch into bootcamp to use Cubase SX 3 for audio production and sequencing (has all my windows-only VST instruments), the interface pops and crackles extremely. It's almost as if the USB interface is losing sync..?
When I turn the buffer up on the drivers, this stops, but it is annoying as I like to have low latency when recording for direct monitoring.
Can anyone give me any insight into why this might be happening?
I know this is an audiophile-type question, but I thought I might as well give it a go. Or heck, if you wanna direct me somewhere where they might be able to help me!
Cheers!
Chris
P.S. Using a MBP 2.5GHZ 2GB RAM

Audio error with garageband and external usb audio interface

I am using Garageband 2.0.3. under ios 8.0.2 on my iPad 3 and via camera adapter a USB audio interface Focusrite Scarlett 2i4 or a Presonus iTwo.
When I start Garageband, it works well, the audio interfaces are recognized and I can record a track.
As soon as I switch from instrumtent to track view, the audio path is completely disturbed and all I can hear is some noise from the speaker.
Then I have to unplug the usb cable and plug it in again. Then audio works until I switch back to the instrument menu.
When I use the headphone output only there is no problem with Garageband and everything works fine.
Other applications audio applications don't show any error with each of the two audio interfaces.
Any feedback is very much appreciated, thanks.
Harald

I have this exact issue. However, I tried the Loopy app after after GB crashed and received an error message saying that core audio is not available. Rebooting resolves but the problem repeats. Any suggestions as to fixes? Btw; I have no such problem with Ipad 2 and ios 7.

Can i use my usb audio interface with apple tv? For example Focusrite 2i2

Afraid not - AppleTV does not support USB audio devices.
I assume you don't mean using the device as an optical input for the computer, connecting AppleTV's optical out to it.

Will Garageband on an IMAC with OS 10.7 work with a Tascam us-600 USB audio interface

I need a USB audio interface to read in DAT tapes from a Tascam DA20 recorder. I want to use the S/PDIF digital output from the recorder. Has anyone used the Tascam US-600 with the IMAC and Garageband? Any other recommendations for a USB interface that will accommodate S/PDIF as well as XLR Mic inputs for under $200?

Been there, done that.
I can select the device (US-144), but I do not get any choice for the output channel. The default is to go the analog channel ( channels 1 and 2).
However - I did find a workaround. There is an opensource package called Soundflower:
http://code.google.com/p/soundflower/
From the description:
"Soundflower is a MacOS system extension that allows applications to pass audio to other applications. Soundflower is easy to use, it simply presents itself as an audio device, allowing any audio application to send and receive audio with no other support needed."
This allows me to set the output channel for garage band (and any other app, e.g. itunes) to the digital S/PDIF output.
It would be nice if this functionality was built in to Mac OS X...

Audio input setup with a USB audio interface

When i plug my USB audio interface into the USB port, GB gives me a message that it has been detected, and it shows up in the audio input preferences.
But it doesn't seem to be listening. Signals light up on the interface when i speak into the mike, but not on my GB.
I also switched to the device I'm using in my Mac input sound preferences.
Hints, anyone?

Nothing - it's a new project. Thought maybe I ought to get the input device working before starting.

USB Audio Interface Mystery

I have an HP Envy TouchSmart m7. Purchased it with Win 8 and upgraded to Win 8.1 update 1 (with August 2014 update).
No issues with the exception of a USB device. I normally have not used any USB devices - no USB keyboard, no USB printer, etc.. I have used a USB mouse once in a blue moon - but I do use a USB audio interface for my MIDI keyboard regularly.
It works fine until I connect a cable from any of the outputs to a mixer or amp. Within minutes, I hear a click and my audio driver stops responding as if the device rebooted - I'm assuming because of a USB power or data drop-out. I've replaced my audio interface, tried different power sources, different locations, all types of surge strips, modified power settings, replaced mixers, upgraded my BIOS, checked Windows updates, been talking with the maker of my audio interface (who even sent me custom drivers) and talking with the makers of my music software - all of them are at wits end saying to simply use another computer.
Help - help and help! I cannot perform with my audio interface not working. I have to connect it in order to hear sound. Everything seems to point to hardware on my laptop. Any ideas or fixes for this laptop?
Thanks,
Chris

Hello,
AS I stated earlier - the maker of the problematic device (which has a solid reputation) has sent me new drivers that aren't widely available although the drivers seemed and still seem solid and I've never mentioned nor had an issue with latency. Although you said I didn't mention updating any of the drivers, I may have inferred it by saying I installed any and all Windows updates which included drivers.
I have worked with PC's for 20 years, building, supporting, programming, etc.. I have seen a plethora of problems that run the gamut of easy to very complex and even to unexplainable - which I usually don't accept.. lol. This laptop runs smooth and I've tuned it up as my main music machine but this issue runs pretty deep and on the surface I can't see a driver issue, no latency issues and no updates pending for anything. What has my curiousity and perhaps I've not been as detailed as I shoud have been but that this problem does NOT occur and may never have occurred if I only used headphones. It only happens when a cable - any cable - is plugged up from my audio device to another device like a mixer or amp.
That's why I explored grouding issues, electrical possibilities etc. This may be a complex combination of several factors. Maybe a USB issue, along with a driver and/or even a deep OS issue along with grounding?
Thanks for the link to Windows 8 Tuning Tips for Audio processing but honestly, I had already performed these modifications way before I found that article and read it even before you posted the link. But thanks for being thorough.
I'd actually be happy if I had to address some clicking or popping - but a complete failure when only cables are connected? What can I do in the cabling to prevent surges? I hate to purchase expensive equipment to troubleshoot this, find a surge issue only to have to purchase another laptop, audio interface or something. Throwing more money at it for only troubleshooting purposes doesn't seem pleasant to me.
I have blue screen logs, memory dump files, etc which have been handed over to Focusrite and still nothing. I'd like to install Win 10 on it to see if this reoccurs or drop back to Win 7. I don't know what to do,,, my first audio interface device to fulfill my dreams of playing live performances and I hit this.. Agh!!!
Frustrated but still willing to troubleshoot,
Thanks,
Chris

Thanks for the response, but I do not have a midi interface. I am using a midi to usb connector cable, thus bypassing the need for a Midi interface.
The Mac reads the USB cable as a midi device, but not the keyboard that I am trying to use as a controller. I have tried it with my korg sp 300 and with my Nord Electro 2.
Thoughts?
Thanks,
Tristan
Tristan...
This is what you have, correct?
http://www.alesis.com/usbmidicable
This from Alesis..
"The AudioLink Series USB cable receives and outputs MIDI signal thanks to its internal interface. The USB-MIDI Cable connects plug-and-play to your Mac or PC for an all-in-one USB-MIDI solution."
Notice, -internal interface-. What you have is a simple USB MIDI Interface. Most MIDI interfaces are USB.
My point is (was), MIDI OUT of the Korg goes to the connector marked MIDI IN on the Alesis, those new to MIDI often get this wrong.

Set up USB audio interface in lion osx 10.7?

Hi
Having no success in connecting two USB audio interfaces in lion os x 10.7.2.
One is a focusrite saffire 6 USB
The other is a numark omni control
Have installed drivers for both (from their installation discs)
Neither is being recognised - have attempted to change input/output in sounds (within system pref) - simply no option there to select either
Is it anything to do with them being USB 1.1 perhaps?
Any ideas?

Thanks for the advice mate.
I should point out that I am without home broadband at present...
but before I picked up your message, I had checked both the numark and focusrite websites on my iPhone using 3G connection. I was able to download, transfer and install the current numark driver from my phone to my desktop - and the omni control appears to be working fine now.
I wasn't able to download the focusrite USB driver to my iPhone for some reason though. Better head out with a memory stick to use proper t'internet at my sister's tomorrow I guess!
I do wish that it was as easy to setup audio on new os x as on my novation xiosynth - it truly seems to be a 'plug and play' device.
Anyhow, much appreciated - thank you again for posting me the links.
Have a great day
