USB audio problems under Leopard

I was a long time upgrading to Leopard, but since I have done so I've had nothing but problems with audio. I have an Event EZBus connected via USB and it worked fine under all the operating systems up till now.
It seems to work fine initially in any program, whether I'm streaming audio from the internet, or using an audio program like Digital Performer. But after varying amounts of usage of audio, it begins to stutter, with longer intervals at first, broken by brief soft static sounds, then the stuttering intervals get shorter and shorter each time I play something, until it's more stutter than audio.
Quitting and restarting whatever application I'm using often cures the problem temporarily, but then it just starts again and gets worse and worse until I quit and restart again.
I've tried every kind of troubleshooting I know of and am at my wit's end. Did Apple make some major change to Core Audio that now has rendered my audio interface obsolete, or does anyone have any idea what might be causing this and what can be done about it?
Thanks.
Marie

Apparently there were drivers for Jaguar and Panther. However, check out this web page and see if it helps. http://www.jackosx.com/download.html

Tx2620 usb audio problems

Hello everyone. I'm planning to use my tx2620 tabletpc for music production and DJing purposes. I have an ESI Maya 44 usb audio interface, a semi professional USB 1.0 card with multiple inputs and outputs. Since I first installed it, I've been unable to get it to work properly.
Audio quality is terrible, full of clicks and pops under any latency setting on the ASIO driver. I've tried every possible Vista configuration to get it to work as it should, to no avail... (wifi off, antivirus off, only minimum services active,...) but the audio still has clicks and pops.
The card has been tested on other computers with the same drivers and ASIO and works just as expected, but it refuses to provide clean sound under the tx2620. I believe there might be some hardware conflict/issue on my machine.
Can anybody help me out. Thanks in advance.

I would try recovering first to eliminate all possibilty of software conflict. If that doesn't work, then I would try all the avaliable USB ports. You have already tried turing off the wireless, which is good. If all that fails, uninstall and reinstall the USB hubs, update your Audio Driver and your Bios. If at that point you still have the problem, then you are probably looking at an incompatability.
-Good Luck

USB audio problems with 2013 iMac

I'm having a strange audio problem with USB microphones and headsets. The issue with my Logitech H650e is shown in this screencast I recorded. In the first part of the screencast, I am not speaking into the mic—yet you can see the levels fluctuating as if there is static playing (not in a natural pattern that you'd see when someone is speaking). In the next part of the video I demonstrate that selecting the built-in iMac mic for input, and then re-selecting the Logitech headset temporarily solves the problem. You can see the input start to fluctuate normally as it should when I am speaking. But at 0:31 in the screencast, you can see the input levels freeze and stop registering anything. I continued to speak until the end of the screencast, but no input was detected. For this screencast, I was on a Go To Webinar call, but the problem occurs regardless of whether I'm using Skype, Go To Webinar, GarageBand or any other software.
The problem with my Blue Yeti USB microphone is also different. In that case, the input does not freeze as it does with the Logitech headset. The levels appear as you would expect, and it seems to work. However, the person on the other end can hear static in the background, even though I don't hear it in my own headphones. I learned this because I just tried to do a Skype interview with the Blue Yeti, and the interviewer told me they could hear static. We closed Skype and called each other back twice, but the problem persisted. Then, suspecting the problem was related to what I described above with the Logitech, I unplugged the Yeti and then plugged it into my Macbook Air 2013 (also running Mavericks). Lo and behold the static completely disappeared.
My Griffin iMic and Audio Technica lavalier mic (attached to the iMic) behaves similarly to the Yeti, except in this case I can hear the static when I speak with my monitoring headphones. The input works but I get a lot of cracking and static in the background. This was confirmed by calling the Skype Test Call number and recording a message, which is then played back.
Here are the facts:
All 3 of my USB audio microphones/headsets do not work with my 2013 iMac running Mavericks
All 3 of these microphones/headsets worked fine with my 2008 Mac Pro running Mountain Lion
All 3 of these microphones/headsets work fine with my 2013 Macbook Air running Mavericks
In this other thread, several people are reporting similar issues with the iMac 2013 and Mavericks. At least two people did not have the issue when the iMac 2013 was running Mountain Lion. This of course suggests the issue is the combination of the iMac 2013 and Mavericks.

Did 4.1.2 fix YOUR USB Audio problems? Not mine...

I'm curious to hear from the other folks who were having issues with 4.1.1 freezing/sluggish while using USB speakers or USB audio converters. I have a Xitel USB-to-SPDIF converter that has worked flawlessly since 10.3 in EVERY app...until GB 4.1.1. I was expecting 4.1.2 to fix it for me as suggested, however there seems to be no change for me. If I select either USB Audio in GB preferences, or "System Setting" (which is always my USB Audio), GB is totally hosed. Spinning beachball, freezing, can only Force Quit. If I select Built-in Audio (internal speaker), then all is well. If I switch back to USB Audio, totally hosed again. What's unbelievable is that there isn't even a 3rd-party driver in the mix here, the Xitel uses Apple's built-in generic USB audio device support!!
Did 4.1.2 fix YOUR USB Audio woes??
Apple, still more work to do! Please help!

I'm also having audio issues on my new late 2013 iMac via the USB headset. Audio starts playing fine and then static starts creeping into the audio until it drowns out the sound. Only way to fix is to unplug the headset and then plug it back into the USB port.
I've tested the headset on other PCs and my older iMac and the issue doesn't show up.
I've re-installed Mavericks on the iMac, without nuking my data, but that still doesn't solve the issue.
I've logged a case with Apple support and they had me run a program which gathered up a bunch of information to send to their engineering team. No updates yet so far.
Just one question for those that also have this issue. Did you restore your data from a Time Machine backup, or is this issue also happening on the Mac that's fresh out of the box?
I'm wondering if this issue could be caused by restoring data from my Time Machine, but I don't want to go through the hassle of nuking my entier hard drive and having to reinstall everything from scratch just to fix this issue.

USB audio problem only in one user account

I have my Macbook Pro 2.2 set up as a media center for my stereo. It's been working great, connected via USB to a DAC. Yesterday it suddenly started to act up and their was a very loud white noise sound mixed in with the audio (in all audio playing apps - Player, iTunes). This ONLY happens in my primary user account on this Mac OS X (10.5.2). I have another user account on the machine that sounds fine, and it's fine on my bootcamp XP. It's fine on my SuperDuper backup also (but that's a few weeks old and don't want to revert to it if I can fix this). Any ideas? If I could just copy some files from my backup or the good user account that would be great. I don't know what I did that might have triggered it. I didn't install any new software since it was working. It basically sounds like an extremely high noise floor. It also goes in and out like a bad FM signal. Audio from the built-in speakers is fine.
Thanks.

USB Audio problem

Good day, folks:
Specifics:
- PowerBook G4 Aluminum (2003)
- About a month beyond extended Apple Care warrant
- Mac OS X 10.4.7
- 1.25 GB RAM
- Logitech 250 USB headset
- MacAlly IceCam
(Please forgive if this is repetitive; I did not see this specific problem referenced in earlier posts.)
I no longer can hear anything through my Logitech USB headset using either USB port on my PowerBook. About a month ago, I could no longer use the headset through the right USB port after trying to edit a file in Bias Peak 4 LE, but I didn't complain because I still had use of the left USB port.
Now, after using a Macally IceCam last night in the left USB port, I find I can no longer hear anything out of the headset when it is connected to the left USB port.
Yes, the headset does appear as connected in Skype's audio preferences. (That is what the headset is used for most.)
Yes, the headset does appear as connected in Apple's Audio Midi Set Up.
Yes, the headset does appear as connected in Apple's System Preferences.
Yes, other non-audio devices (i.e. Apple wired keyboard, Kensington, USB mouse, HP LaserJet 1012 printer) appear and operate normally in either USB port.
And I just ran the Disk Utility to both verify and repair permissions, then restarted.
Still, no Logitech capability.
Any help with getting one USB working with this device -- I depend on Skype rather heavily -- would be great; getting both ports to work would be supreme.
Thank you in advance for any and all assistance.

OK, so in following up I found a partial answer here:
http://discussions.apple.com/thread.jspa?messageID=2873545&#2873545
This answer, however, doesn't explain why the Logitech USB headphone would have worked fine right out of the box for a couple of months, yet now does NOT work.
And it doesn't explain whether or not the problem (assuming it is lack of power on the laptop USB ports) can be fixed via any setting.
So my followups are:
1. Assuming the problem is lack of power in the USB ports, why would the outage have occurred only after using the Macally IceCam?
2. Should I discontinue using the Macally IceCam in the USB port? (I cannot seem to find a FW camera for the life of me, that's why I settled for that.)
3. Since my laptop is Bluetooth enabled, will any decent Bluetooth earpiece work with Skype for Mac, and can anyone make a good recommendation?
Again, thanks in advance

EMU USB 0404 USB - Audio Problems

Hello forum!
I recently bought an 0404 USB and I am having problems with the audio quality.
Prob 1 - When I plug a guitar into input A, the sound switches between clean and a distorted/clipping/phased kind of sound, and I also get some clicks. I have tried adjusting the ground switch position and the buffer size for the input, but with no success. The sound switches from clean to "dirty" (if that is the correct term) and back at random and it is almost impossible to get a clean sound to record with the equipment. Can anyone help me solve this?
Prob 2 - when I do get a clean signal - the playback is of an inferior quality and there are audible clicks (nothing to do with the metronome) more like a static noise.
Prob 3 - I can't adjust the sample rate in the EMU control software - it only lets me select 41khz. I have only used it with Cubase so far which I believe supports a max sample rate of 41kHZ- but I don't know if it will be the same with Sonar. Note interface is definitely running in USB 2.0 mode as it states this in the EMU software controller.
Prob 4 - since installing the software for EMU 0404 my computer has only been starting in safe mode (I have to adjust the display settings etc) and it automatically restarts when I shut the computer down.... Im running the computer in XP SP2.
Any help you can offer is appreciated. Happy recording guys
PS I have already sent these questions to the EMU product support guys, but they are taking a while to get back to me.

When you use ASIO driver mode, for samplerate settings, E-MU follows settings done in software ... as like in Cubase LE (you can test this by leaving the E-MU control panel open while changing the samplerate setting in Cubase).
You set the samplerate through Cubase Project Setup:
http://img213.imageshack.us/img213/5609/clesreb2.jpg
Just use native ASIO drivers in ASIO capable software (there are Sonar LE, Cubase LE and Live 4 Lite bundled w/ the card) with this device. Remember also set the ASIO latency properly (one instrument w/o plug-ins in path ... you should be able to go as low as 2ms).
If you like just to play guitar through E-MU interface then, just use ASIO capable software like VSTHost for input/output (you'll need to load least one VST plug-in into VSTHost to get audio through ... maybe Voxengo SPAN or Sonalksis FreeG is the one w/o effect in audio).

If this area of music is new to you then, more plug-ins can be found through KVR.

Audio problem under win2000

I buy 6309 mainboard many years ago. During the past time, the mainboard work very well. Now I try to use the AC sound function on maindboard to recorder sound from my microphone using the recorder of win2000 system. But it get a lots of nose in it. I don't know what's the problem. But if I use the voice recongnizse funtion to test the audio. It can work well now. Under the visual basic development, if I use the multimedia control to record sound it still can not work. But if I use the "microsoft speech SDK" the record sound, It can work well. I have been try all the way. I can not find where's the problem.
Is there anybody can help?

USB audio problems

Probook 4520s Win 7 64 bit.
I have a USB wireless audio transmitter, but when I plug the transmitter into USB, the sound in my pc speakers wil not automatic turn of and transmit the sound through the USB transmitter.
I have try on another pc (not a HP) and it worked fine.
Can anyone help me??

I would test the issue in a new user
if the issue is still there in the new user then I would reinstall the os doing an archive and install
or your could reset the smc and the pram
(smc) shut the computer down then unplug everything from the computer then take the battery out then hold down the power button for 5 seconds then put the battery back and then the ac adapter and then start the computer
(pram) you restart the computer holding down the apple key option key P and R till you hear the start up sound twice
if the issue is not in a new user then i would remove the plist for the application that you are running
it is located in your home folder under library and then the preferences folder
if that does not work then move the whole preferences folder to the dekstop
if that does not work then i would move the whole library folder to the desktop
now if the preferences or the library folder solve the issue then you will add the folders content back to were it goes and select do not replace for all of the items.
if it still does not work then i would boot to the install disk and then run the disk utility which is under the utilities menu at the top of the screen when started from the disk
if it is still there then you will need to reinstall the os
if disk utility found and error then it is an erase and install
if not then it is an archive and install
hope this helps you

Apple LED 24" Cinema Display audio problem under 10.6.8 (with post fix)

Hi all,
I'm using an Apple LED 24" Cinema Display with a 2010 MBP 15" and had been using 10.6.8 without problem. After installing the post-fix I now get static noice on (clipping?) when music contains lots of base. If I switch the output to my MBP's built-in speakers then the audio is fine.
Is there any way to un-install the 10.6.8 post-fix?
Thanks,
Yanik

Solved the issue. This issue coming up after installing the 10.6.8 supplemental update was just a considence. I ended up tracing the issue back to my Atlona AT-MDP21 Mini-DisplayPort KVM switch and after fiddling with cables the issue went away.

USB Audio Problems Late 2013 iMac - Clicking / Popping / Dropouts

I am having audio clicking and popping issues with a brand new late model 2013 iMac and a USB 2.0 multi-channel audio recording interface. Here is what I have learned so far:
Clicking and popping is occurring in both directions - playback and recording. I am not having any issues with internal audio, so this was easy to verify.
The same issue appears in many threads in Apple Support Communities and in various recording/pro audio forums, so this seems to be a common issue.
The issue is independent of the audio interface that is used. (I am using a brand new Focusrite Scarlett 18i20 that I purchased specifically to use with my new iMac, but the forums report the same issues for a variety of other interfaces and audio devices.)
Five potential root causes are mentioned in the various forums:
1) USB 3.0 compatibility issues - poor backward compatibility or other issues
2) Fusion Drive activity - artifacts caused by drive "swapping"
3) OS X version - newer versions may be worse than old versions
4) App Nap - ?
5) Driver issues
Potential short-term solutions include:
1) Change driver - The "Class Compliant Mode" app (that I downloaded from the link on the Focusrite website) improved the issue for me, but clicking and popping occurs every few seconds instead of constantly.
2) Exchange the Fusion Drive for a conventional 7200 RMP hard drive - Forums report that this does not fix the issue.
3) Install older version of OS - Forums report that this does not fix the issue.
4) Disable App Nap - Forums report that this does not fix the issue.
5) Belkin Thunderbolt express dock - Forums report that a Thunderbolt hub with USB gives excellent results, but the only one I am aware of is the Belkin one which is ~$300. (I will not pay $300 to fix thousands of dollars of new equipment that should not need to be fixed!!!)
6) Apple Care's advice was an SMC reset (essentially a reboot), which clearly did not work. The person that I talked to was not aware of this being a known issue.
I am at a point where I need to decide whether or not to get a refund for this iMac since my primary reason for getting this new computer was recording. So...can anyone help to answer these questions:
Has Apple acknowleged this issue? If so, has Apple committed to fixing this issue via a software upgrade or have they admitted that this is a hardware limitation that is not fixable?
Has anyone found a free or inexpensive workaround (i.e. not the $300 Belkin dock) that completely elimiates this issue?

I'm also having audio issues on my new late 2013 iMac via the USB headset. Audio starts playing fine and then static starts creeping into the audio until it drowns out the sound. Only way to fix is to unplug the headset and then plug it back into the USB port.
I've tested the headset on other PCs and my older iMac and the issue doesn't show up.
I've re-installed Mavericks on the iMac, without nuking my data, but that still doesn't solve the issue.
I've logged a case with Apple support and they had me run a program which gathered up a bunch of information to send to their engineering team. No updates yet so far.
Just one question for those that also have this issue. Did you restore your data from a Time Machine backup, or is this issue also happening on the Mac that's fresh out of the box?

RosettaStone Product Activiation Problem under Leopard

Hi - After the installation of latest RosettaStone language software you have to enter its activation id key. after transmitting - the program hangs and never recovers again. running on mac os 10.5.1 and RosettaStone v3.0.42A / ITA1 v7.1. Thanks

Problem solved. Activation was now possible. Guess RosettaStone had a problem with their activation server.

Boot problem under Leopard

Sometimes my Mac Pro wrongly boots on Windows XP (on a separate 250 Go HD) and not on my favourite preselected Leopard HD.
When I check the boot disk in Leopard properties, it appears that the Mac OS 10.5.1 disk is deselected (though I had selected it previously and securely locked its access). So, I have to reselect it again in Leopard and in XP.
Is that a Leopard bug? I notice that it happens more frequently if I plug my Logitech extreme joystick or when I have a DVD (software) within the DVD drive.
If someone knows how to get rid of this bug, please let me know. Thanks!
Regards,
Butchan (Tokyo)

Plugging things in updates nvram device tree. Or that Logitech device.
XP may be set to assume that a DVDs presence means boot from alternate media?

Burning Problem under leopard

Hi Everybody,
I'm writting here because I met a burning problem with my iMac CoreDuo. I manage to erase a DVD RW, but no way to burn a DVD or a DVDRW : the burn session begins, but stop after few minutes and eject the DVD (partially written).

I was able to burn DL DVD's with 10.4.11, which is what shipped with my MBP when I purchased it. I haven't had need to burn a another DL DVD until now, approx 4 months later.
Does anyone out there have any suggestions on this? At this point I'm pondering waiting to see if 10.5.2 resolves the issue. If not, I suppose a trip to the Genius Bar is in order.

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

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.
