USB Audio Interface not working anymore

I have a Presonus Audiobox USB Audio Interface. Worked perfectly until I updated to Mavericks, now I get a screeching noise when used and the sound switches to the built in Mac sound.
So then I reboot and it does it again. The Audio box doesnt have any software since its a plug and play. Any help?

Usb hotspot is not working anymore since i installed itunes 10.6.3

USB hotspot is not working anymore... since i installed itunes 10.6.3
Please help me... how can i fix it.
I have wondows 7.

1.- Thanks for answering.
2.- I think I did not explain myself properly: The iPod is detected by both Windows and iTunes 10.5.3 64bit version.
The problem lies in that now after all the failures and the loss of my music (imagine I have to rip my entire CD collection again) whenever I try to sync my iTunes collection to my iPad (either on a single batch or album by album) a -50 o -69 error appears.
UPDATE: Now whenever I connect my iPod to the computer, it is recognized by Windows, but iTunes tells me that I have to restore it.
I cannot but commend Apple Inc. on his efforts to make a 9 months iPod unsuable. Sincerely this has brought me back to the worst of the 90s with MS.
UPDATE 2: Please let me add that with the previous iTunes version everything was ok. But, as soon as I installed the new Itunes (10.5.3 64bit) version the misery began. Unfortunately when I try to install the previous version I'm not allowed by the program and am referred to the newest buggy one.

Core 1 usb audio interface not supported by OS x 10.10?

Today I bought a Alesis Core 1 USB audio interface in order to connect my guitar to my mac and garageband.
My mac Book pro (with Yosemite) does not pass through any signal from my guitar.
Is this a known problem? Do I need to install another driver, and where can I get this?

The photos are located in your iPhoto Library package which, by default, is located in your Pictures folder and is independent of the application.
What system are you running? If it's anything earlier than Yosemite you won't be able to download iPhoto as the only version available from the App Store is 9.6 which only works with Yosemite.

Hi all, in answer to the above suggestions:
No the 10g database and listener is completely down (no services belonging to the new 10g database are running). I checked also alle the logs, but no messages anymore since saturday.
What I did notice: Oracle92HTTPserver (a service normally started automatically) does not start. When I start it, it gives me a message that there is nothing to do and that the service therefore is not started. So the HTTP-server itself is not working anymore. I can't find any files changed by th installation in the Ora92 home Apache directories. All seems as it was before the installation And still it won't start....
Does anybody have other suggestions? Please help.
Thanks in advance,
Jan.

Emagic emi 26 audio interface not working

I want to turn my old dell inspiron 8100 PIII 1.2 Ghz / 512 MB RAM into my sound center, attached to active loudspeakers and a huge USB external harddrive.
Running arch linux and recently did pacman -Suy.
The internal sound card is broken, I only get distorted sounds (in windows as well).
I want to use my a bit dated emagic emi 26 usb audio interface.
The linux installations has (the exact paths are maybe different, writing from another machine now):
/lib/modules/2.6.27-9-generic/kernel/drivers/usb/misc/emi26.ko
/lib/firmware/emi26
So it seems the interface is supported.
However, when I plug it in, nothing happens. Some LEDs light up on the interface,
but /proc/asound/cards only shows my Maestro3 sound card, also alsamixer
doesn't see the device.
If I enter "lsusb", the terminal hangs, no Ctrl-C helps! I can't even kill -9 it as root!
I have snd_usb_audio and emi26 in my MODULES in rc.conf, while having
!audio and !usb_midi there too.
lsmod shows that emi26 is loaded, as well as snd_usb_audio.
Does anybody have an idea on how to go about this?
I guess there must be some problem with the driver...
Thanks for any help

Hello,
"and now I cannot get sound out of my interface, even after trying to unistall that program and reinstall my interface driver"
Try using AppZapper: http://www.apple.com/downloads/macosx/systemdiskutilities/appzapper.html
This way you make sure you have UNinstalled all the associated files.

in the end M-audio emailed me and blamed logic,they told me to contact apple,W@**ERS!!
I'm new to this apple discussions business and hope someone can help!!

Welcome to the wonderful world of M-Audio!!! Now, what you are doing is perfectly NORMAL. You need to hook up speakers to your audio interface. Where the little diagram says so:
http://www.m-audio.com/layout/imgview.php?i=/images/en/connectivity/big/mobilepr eusbcd779px.gif
See? The reason this is so, is because when you are using this interface, you are BOTH using the inputs AND outputs. Logic always works like this, it is a requirement to use "a full-duplex sound card" which means a sound card that has inputs and outputs.

M-audio blaming everyone else is not new, however, your "issue" is a user issue, not a gear issue.

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
GKap

Hello 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

Audio interfaces not working in mavericks ?

Interfaces are recognized and output signal just fine but the input signal breaks up after an undetermined amount of time. Tried it with year old scratlett interface, and now with an apogee duet and the same glitch occurs. Thus it is not a flaw in the audio interfaces. The glitch must be fixed. Immediately. For a new system to not support a basic interface is totally unnacceptable. Fix it. Fix it now.

Thanks Gary.
The fact that you're getting results with that interface is reassuring.
For $30 it would be worth it for me to pick one up just to see if it works with my mac.
I'm starting to suspect driver/firmware issues with the pro-audio stuff, since Apogee, Focusrite, Roland, Tascam and others are all issuing "Mavericks" patches, with varied results.
As far as powered hubs, passive hubs, etc. as discussed in the 2 threads you indicated, I've been through it all for about a month.
Can you tell me what clock source is the UCA222 using? (default or external)
You can find this in Audio MIDI Setup utility.
Also, did you install any drivers/firmware as found on this page?

Thanks again for your insights.

Audio interface not working with Mavericks

I know this has been asked before, but I only just got Mavericks and it won't recognise my M-Audio MobilePre as an output source. I've tried installing new drivers but it didn't work. Now I have $800+ of equipment that I can't use. Is there anything else I can try to fix it? Or can I downgrade my OS?

I think it's something you need to take up with Avid.
Firstly, do Avid support the hardware on Mavericks? If they do, then that means it's a unique problem which hopefully can be fixed.
Secondly, are any relevant messages being logged when you access System Preferences > Sound or Audio MIDI Setup? Open Console utility, and have a look. You can filter for particular search terms, but start by looking at the time you do it.

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
