USB Audio device - CPU usage spikes - w520

I have a LENOVO W520 4276CTO
Intel Core i7 @ 2.40GHz
8.00 GB Dual-Channel DDR3 @ 664MHz
Whenever a USB Audio device is enabled I am experiencing cpu spikes every 8 seconds approx.
This activity happens with 2 different usb audio devices from 2 different vendors.
I have used various tools to try and track the problem down such as latency checkers
LatencyMon indicates a large amount of ISR and DPC activity on the
usbport.sys driver
i've been trying to resolve this problem for weeks now and would appreciate any help .
Thanks
Glenn

What USB controller are you using? Not saying it will address your issue but there is a driver update for the Renesas controller (2.1.32.0). When I installed it I had to manually update the driver.
For your USB devices, are you using their latest drivers?
You may also want to review kb2529073 to check whether the kb is applicable to you.
I have played around with a USB external audio device in a dynadock (Toshiba) and no DPC issues but an issue with not being able to run 'Smart Audio' in cpl. The message is 'Failed to initialize smart audio'. So I have to use the system utilities to control the Conexant audio. Have you noticed any issues with the onboard audio tools and your external audio device?
You may also wish to check the Microsoft site for any Win 7 USB related hotfixes that may help.

Simple Java 3D programs CPU Usage spikes to up to 90 percent!

Hi, everyone. Im completely new to Java 3D and Im toying around with basic program structure right now. My code is based off of that in the first chapter on 3D in Killer Game Programming in Java. I removed most of the scene elements, replacing them with a simple grid, Maya style. (Yes, Im starting off small, but my ambitions are grand I intend on creating a polygonal modeling and animation toolset. After all, the Maya PLE is dead damn you, Autodesk! and I just plain dislike Blender.) I implement a simple OrbitBehavior as a means for the user to navigate the scene. That part was basically copy and paste from Andrew Davisons code. The mystery, then, is why the programs framerate drops below 1 FPS and its CPU Usage spikes to up to 90 percent, according to the Task Manager, when I tumble the scene. Id appreciate anyone taking the time to look at the code and trying to identify the problem area. (Ive undoubtedly missed something totally newbish. -.-) Thank you!
(Also, I had the worst possible time wrestling with the posting process. Is anyone else having trouble editing their posts before submitting them?)

Huh. A simple call to View.setMinimumFrameCycleTime() fixed the problem. How odd that there effectively is no default maximum framerate. Of course simple programs like these, rendered as many times as possible every second, are going to consume all possible CPU usage...

No Digital Output available in Playback devices (USB audio device)

If one has USB audio device with coax/toslink out, with proper drivers (like ie TurtleBeach Micro Advantage) available & installed then Digital Output is available to select in Playback devices. (and one can play AC3/DTS to external amplifier with ie
VLC or MPC-HT with AC3Filter DS filter)
But some USB devices (ie Phonic Digitrack -
http://www.phonic.com/en/digitrack.html ) do NOT come with drivers (as Windows has default build in). Digitrack uses TI
Burr-Brown USB Audio Codec 2906 -
http://www.ti.com/product/pcm2906
Sadly these Windows drivers do NOT have a clue about what the device actually has as inputs/outputs
So even it had coax digital out & the sound IS send via it, the actual data send is in right way, not recognized/played correctly by Digital Amplifier (AC3/DTS)
Does anybody know of a hack to make Digital Out available?
Seb

Hi,
Generally speaking, An Audio Device do need more driver besides USB driver to make itself work properly. In terms of your situation, USB driver is not enough to make your Audio Device works properly. I think S.Sengupta
is right. Actually it would be better to contact Digitrack support to confirm its product compatibility with Windows 7.

USB audio device loses output connection

I use a MobilePRE USB interface and had no problems until recently. My iMac is set to never sleep but if I do not use the computer for a few hours the output from the MobilePre is gone.If I change to the driver to the internal headphone output on the Mac all is fine but in order to use the MobilePre as output I must restart, then it is fine until the next day or a few hour later.
The same time that this problem developed, about a month ago, I also noticed a low level snap or popping sound. This happens through my external speakers and is triggered by any sound activity approximately 30 seconds later. It even happens with the volume turned all the way down and sounds like a connection is being made. Like I said these two problems started about a month ago around the time Apple was sending a lot of updates. I have read a long thread on the OSX forum and know this is a pervasive problem with no solution yet. I mention it here as a curiosity as it started around the same time as the USB audio device problem. My hunch is that it has something to do with a recent update.
I don't think this is a GarageBand problem because it is the same no matter what software is outputting. I ask on this forum because there some knowledgeable audio heads here.

Check the archlinux news item which calls for an entry in kernel commandline .................

Volume control with USB Audio device

Hello all.
I have just purchased a cheap USB audio device to connect my HiFi to my laptop with only one, neat USB lead and a USB hub - meaning I no longer need several USB wires and an audio cable across my desk.
This works fine, but I have just noticed that the volume control in OS X has no effect on the output now, only Mute or On. The volume within iTunes works fine, but not the OS X one.
Any way I can avoid having to use the volume on the hifi when using the USB Audio device?
Many thanks.

Don't think so unless that piece of hardware came with compatible Mac software to control it.

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

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.

OS X 10.7–10.10 iSub workarounds? USB audio devices?

The old Harman/Kardon iSub (USB subwoofer) never worked right with Intel Macs—but it was always a software issue, which could be worked around: I read years ago about people connecting USB headphones or speakers, which "tricked" the Mac into sending audio to the iSub. (In the case of headphones, I assume they would also use Audio MIDI Setup to make a Multi-Output device allowing sounds from your normal speakers at the same time as the 'phones.)
Does that trick still work in Yosemite? If not, when did it stop working? Can't seem to get it working on my 10.7 laptop with Jabra Revo Wireless headphones connected to USB (they have wired modes as well as wireless).
Any other workarounds? I'd love to get this thing going with either 10.7 or 10.10! Requiring an additional USB audio device isn't a great workaround... but I happen to have such a device anyway!
Thanks for any ideas.

JDev 10.0.1.3 CPU Usage Spikes - Somewhat Serious!

I have noticed that JdevW.exe process in task menager has annoying CPU usage spikes every 2-3 seconds. This does NOT happen if I use 10.0.1.2 version.
I have fairly powerful Dell workstation. Any ideas? Configuration problem?
BTW embedded OC4J is not running.

Shay,
I am actually not doing anything. As soon as I open JDev I can see (and feel) that performance problem. Every time the 'spike' occurs, mouse gets 'frozen' for a fraction of a second. It is anoying a bit.
My coworker's installation do not have that problem and I wonder if add-ons that I have downloaded and installed would create this behavior. BTW, how do I figure out what add-ons (plugins) I got?
I can see 'jucheck.exe' and 'jusched.exe' processes as well but even when I killed them the spikes occur.
Any thought?

USB Headset detected, but not being loaded as a USB audio device.

Hey,
I just bought a Gigaware USB Premium Audio headset with Mic, and I'm currently trying to get it to work. It does show up under lsusb:

It's showing up as the C-Media Electionics, Inc. device. Unfortunately, for an unknown reason to me, it doesn't want to be set up as a sound card, as in DMESG:

Any helps much appreciated,

The format says Mac OS Extended. All of the settings were set during the disk image restore process. Even if I format the flash drive as extended journaled or some other format, all of these settings are reverted when I do the restore from the disk image. I will just copy all of the information that disk utility has so that you can see it.

Cannot see my plugged in USB audio device (Schiit Loki DAC)

I can not see my plugged in USB audio device (Schiit Loki DAC). Can anyone help?

According to the manufacturer, Loki does not need any driver to work with Mac. Funny thing is, I tried it on an old Macbook runing OS X Version 10.4.6 and it worked! Schiit Loki showed up in both Sound and Midi settings. I then took the Loki to the local Apple Store and tried it on their new Macbook Air (same as mine running OS X 10.9.1 and it failed again. The Macbook Air just could not see my device at all.
Talked with one of their technical experts and he just told me to get a driver from the manufacturer, he wasn't very helpful. I am about to give up: convinced that Loki simply will not work with Macbook Air for some reason. If anyone had an experience that showed otherwise, I would be very happy to know. Thanks for helping.

Usb audio device support in Mavericks

It seems everywhere I look USB audio devices do not work (or do not work well at all) with Mavericks. With yet another OS X update coming I'm nervous that developers will be even further behind Apple's USB audio chaos. Does anyone know what may be on the horizon? I'll have to downgrade if this there's no remedy. I'm amazed there's so little support in Mavericks for USB audio - especially since all new Macs have no distinct mic input.

Do you have a question, otherwise your post comes across as a rant.

Recording into Audition 3.0 via Behringer UFO202 USB audio device

I am running Audition 3.0 on a PC with Windows 7 Home Premium. This may not be the proper place for this question, but I was not able to put it on the Adobe Audition 3.0 and earlier forum.
I am trying to record cassettes into Audition via a Behringer UFO202 USB device. I plug in the USB and my computer sees it and I can hear via the headphone output that it is playing. I go to the Windows Recording Mixer and it indicates that a USB audio device is working. However, I cannot get the sound into Audition. It doesn't show up when I record to the edit window or click on the meters to monitor.
I am also using a HT Omega Sound Card, but their support said that it shouldn't interfere.
Any help would be greatly appreciated.
thank you,
New Orleans Audition User

Unfortunately you cannot reduce the levels of audio on it's way into Audition. Audition just records whatever the audio interface sends it. If the levels are that high when recorded into Audition then it is likely that you could be overloading the input to the Behringer interface. You need to somehow reduce the level at source in the analogue domain. Once it is in the audio interface at too high a level then any distortion caused will be burnt into the digital audio file and you won't be able to get rid of it.

USB Audio Device only plays left channel out both speakers.

usually i use my Yamaha Audiogram 3 usb audio device to record things in cubase, and when the cubase settings are set it is fine, but as soon as i close cubase, the left channel of any audio (like itunes playback) plays out of both left and right speakers in the headphones i use. this only happens when the Audiogram 3 is plugged into 1 certain usb port (of 2).
its even fine when i have cubase running in the background while i play music from itunes. it just doesn't make any sense. it also appears to recognize that its stereo in one port, but not the other.
i would suspect it has something to do with the drivers for the usb device (if there even are any), that the drivers it placed into the system only applies to that one usb port, but if thats the case, you would think it would install new drivers for the other port as soon as i plug in my audiogram, but thats not the case.
no cd for the audiogram. you simply plug it in.
ive tried restarting the computer, plugging it in again, trying to change the settings. nothing seems to work. i need the other port to work.

Try resetting the PRAM. Info here:

You may also want to take a look at the Audio MIDI Setup utility and make sure everything is configured properly there.
