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.

Playing iTunes on USB Audio Device

I would like to output all audio from iTunes to a USB audio device I have attached to my Macbook Pro but leave all other audio going to the laptop speakers.
I've looked through iTunes (10) preferences to see if there is an option to select an audio device, but can't find anything.
I have my HiFI plugged into the USB device for playing all my music, but obviously I don't want system sounds etc to play over the HiFi.
Surely there must be a method to tell iTunes what audio output to use.
Anyone got any recommendations?

Here's a solution.

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.

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.

ITunes only outputting left channel through Soundsticks

I've been using the original Harman Kardon Soundsticks (USB type) for about six years now without problems, but just today they've started behaving oddly in iTunes and Front Row. Only the left channel is now output, through BOTH speakers. They work normally when I use the Quicktime player, but not iTunes/FR. If I switch the output to internal speakers, then iTunes outputs both channels normally. I tried deleting the preferences, and updating iTunes to 8.01 from 8.0 but without any difference. Have also tried rebooting, disconnecting and reconnecting the speakers, and the power to the speakers but nothing seems to make any difference. Additionally, there's no "balance" option in System Preferences for USB speakers.
There clearly isn't anything physically wrong with the speakers themselves so can only assume there must be a corrupted preference file or similar, but have no idea where to start looking. Can anybody help?

I have the exact same problem but I use Windows vista into a MOTU Ultralite Firewire interface outputting to some powered monitor speakers. I know the issue has got to be with iTunes because i can open the mp3 in windows media palyer and it plays just fine in proper stereo. It's really annoying and I cant seem to find the solution.

Audio suddenly only on left track now, some music no longer reading.

Hi there,
After just completing a normal export in premiere with no issues, I open up my project again to find that the audio is only playing on the left track in the sound monitor(in premiere) and on my speakers. I have no idea what's going on because I didn't change anything before saving. Also 2 of the .mp3 files suddenly won't play despite being on the timeline.
I have no idea what's going on but I can't fix it - even copied the edit to a new sequence, the problem follows.
As you can see in the image, the sound file has tracks on both left and right but isn't playing and there are no filters on the sound:

Ok:
I selected all the audio clips in my sequence and dragged them all down one audio track. Fixed the damn problem!!! I don't know what was happening and it doesn't explain much but everything went back to normal.
I took and attached a picture of what the audio mixer looked like during playback:
I'm not sure how to expand the audio to show more of the "yellow" line. But you can see a yellow line in the picture here.
** well dragging them fixed it but I can't seem to replicate this fix on every sequence. It's better than nothing but I'm still uncertain.
below you can see the original track on "audio track 3" that for some reason isn't working and above it in "audio track 1" is the same file, just me placing it there newly. It's driving me bonkers.
**UPDATE** The audio tracks, along with some being panned -100, other were set to -infinity on the channel volume. I'm not sure how premiere decided to do this or how I would have prompted it. To fix this i simply changed the channel volume back to 0db

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

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.

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.

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.

IMac into cam adaptor into garage band works,but GB only sees left channel.

iMac into cam adaptor into garage band works,but GB only sees left channel. Do you think it's the wiring of iMIcs USB vs. the camera adaptor? Or is there a switch in GarageBand that will bring in both channels? Thanks!

Sorry, I meant iMic into Camera Adaptor, not iMac. (no option to edit and re post ones own post)

Renaming USB Audio Devices

I have two USB mics, and both get assigned the name "Unknown USB Audio Device" when plugged in. How can change that label of each device so I don't get them confused?

So I think the best way to handle this is to go into Audio MIDI Setup utility and create an aggregate device by clicking the plus at the bottom left corner. Add the single unnamed device, and then give it a new aggregate name by double-clicking on the title. Repeat this for each of the unnamed devices.
This won't rename the orginal device, nor will it remove the unnamed device from the list of audio devices, but it will give you a sure way to select the intended device.

[SOLVED] Udev: recognising plugging/unplugging of USB Audio Device

Hi!
I am trying to write an udev rule to detect if an usb audio device was plugged / unplugged to change my default audio device (in effect this udev rule should run a bash script..).
Right now it looks like that:
KERNEL=="pcmC[D0-9cp]*", DRIVERS=="usb", ACTION=="add", PROGRAM="/bin/bash -c '/home/me/dotfiles/soundconf.sh attached'"
and I have a second rule for "remove" instead of add calling a different parameter.
However, unfortunately the change is not being detected. my sound devices are listed in e.g. /proc/asound/card0/pcm0c etc for my first card and /proc/asound/card4/... for the second.
They are also listed in /proc/asound/NAMEOFCARD (e.g. PCH).
how can i reliably detect if one was plugged or unplugged?
thanks !

please not that my usb soundcard is attached through a usb hub to my laptop and that it was attached when I ran the command, then removed it and attached it again.
tried to use those udev rules:
KERNEL=="pcmC1D1p", DRIVERS=="usb", ACTION=="add", RUN+="/bin/bash -c '/home/me/dotfiles/soundconf.sh attached'"
KERNEL=="pcmC1D1p", DRIVERS=="usb", ACTION=="remove", RUN+="/bin/bash -c '/home/me/dotfiles/soundconf.sh detached'"
to no avail unfortunately...
thanks a lot for your patience and time !

USB Audio Device sometimes not detected. udev, maybe?

I am using an external usb audio device which I usually keep plugged into my machine. I am finding that this device is sometimes not being detected when I boot the computer.
When this happens, issuing the following command:
$ aplay -L
does not list this particular device. Plugging and unplugging the device does not seem to help.
What does seem to resolve the problem is unloading and then reloading the snd_sub_audio kernel module. This is done by issuing the following commands:
# rmmod snd_usb_audio
# modprobe snd_usb_audio
Could anyone give some insight as to why the usb audio device isn't being detected and why this only happen occasionally? Could this be a udev issue? The device in question is an M-Audio Fast Track Pro.

Make a "Genius" appointment at an Apple Store.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.
Keeping your confidential data secure during hardware repair
*An SSD doesn't need to be zeroed.

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 .................

USB Audio Device only plays left channel out both speakers.
