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.

Problem with USB audio device

Hi all
I have many problem with a USB device sound, i have a plantronic headset with a usb adapter to connect on my macbook pro, I have already this problem in the past but i have found a astuce to fix this problem. Before, when i'm on teamspeak 2, 3 or other software to capture audio with my headset, after 10 minutes, the sound make noise and i have a robotic voice... Since mac OS 10.5.7 apple have change the USB audio driver. i have found on internet the previous driver and change it on mac os X but since the new mac os 10.6.5 the problem com back with the previous or the new driver audio. I don't know if other people have this problem but this is very annoying.
I have test my device on windows with boot camp many hour and nothing, no problem of distord sound or robotic voice.
PS : I'm french and my english can be bad, sorry for that.

Apparently, your previous search for audio issues in these forums missed this one: http://discussions.apple.com/message.jspa?messageID=12574650

Why won't 'Speakable Items' Work with USB Audio Input Device (Lexicon Lambda)?

I am new to Apple Macs, yay for me!
I really want to use the 'Speakable Items' feature but unfortunately it just won't work with my Lexicon Lambda external USB Audio device.
Now, the Lambda is plugged in and working, and I know this from using the "Diction' feature which works perfectly.
When I go to System Preferences and click on accessibility>'Speakable items' and I turn on speakable items, I notice that under 'microphone' I'm unable to calibrate the microphone for some reason (if that's at all relevant).
I follow the instructions and have been asking 'what time is it?' and nothing happens
Any ideas?

I'm having the same problem, using 10.8.4. I have been using Speakable Items for a long time, but it's not reacting at all anymore. I'm on a Mac Mini and have tried several inputs, that all work with dictation, and are selectable inputs for Speakable Items. Zoom H4N, Apogee Duet and an UAD Apollo. The only problem I can see, aside from something in the OS, would be that I have SoundFlower and WavTap installed. Will try uninstalling them, to see if that helps.

Mapping Alsa Volume Control for USB SoundCard (C-Media 650)

Hello everyone who is interested in helping me solve my volume control problem!
Lets see, I have sound playback working, currently I am listening to some Foo Fighters mp3s in XMMS using the Alsa plugin, so I can't complain too much.
However, volume control doesn't work. If I set the alsa plugin to use software volume control, then I have volume control but its not ideal and it doesn't help me when I'm not using xmms. When I run alsamixer or open the gnome volume control, I have multiple volume controls for the "Speaker" device. The 1st pair of volume controls do nothing, I can mute them and my music keeps playing... no idea what they're controlling. The 2nd pair ("Speaker 1") DOES control the sound volume. I just need to find a way to remap it or something so I can configure my applications/tray icon/etc to use it. (And preferabbly not the other 6 channels)
In the Gnome sound control, the devices are:
"Speaker" - stereo control that doesn't do anything
and "Speaker 1" - a 7.1 channel (8 sliders) with the first two controlling front left and right sound for my stereo speakers.
I've tried setting xmms to use "speaker 1", but the option is not in the drop-box, tried typing it manually but that didnt work.
I set my tray icon to control "speaker 1" but the sliders don't seem to lock properly and the volume just jumps around, unlocking the channels and not staying balanced or scaling with the slider.
The only way to get the volume to change as expected is to open the gnome volume manager, make sure the channels of "Speaker 1" are UNLOCKED and slide the first 2 sliders to the desired volume.
So I was thinking if I could just remap the first two channels of "speaker 1" to something else using an alias or link or editing asound.state (which just confused me) for example, then I could use my alias to control the sound in my applications. Thanks for any help with this!
Here's some system info that may or may not help:
AMD Athlon 5400 X2

Thanks again!

Some other observations that may be helpful (and, hopefully, get closer to the heart of the problem)...
(1) Whenever VLC is playing audio (as mentioned in previous post, it is only application that works in desired manner), it will show up in Kmix's "Playback Streams" tab. Whenever Wine and Firefox are playing, they do NOT show up in the "Playback Streams" tab.
(2) Kmix will not allow more than one open application to grab the UA-5 sound (e.g. If I open Firefox and play audio, stop playing audio (while leaving Firefox open), then open VLC and try to play audio, VLC will not play audio (unless Firefox is closed)). This is likely a related problem to the problem outlined in the previous post, but it might not be. If it isn't, I'll take advice on how to let KMIX grab multiple audio sources simultaneously on the same sound card.
Thanks for reading!

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

No volume control elements and/or devices found

Hi, I recently installed Arch Linux and I followed the tutorials on how to configure it. At this moment I have Gnome installed and it is working fine, I only have one problem.
Every time if I try to access volume control I get the following error:
"No volume control elements and/or devices found"
I'm relatively new to Linux so it might be me just being stupid(Maybe I just don't have the right packages installed) but I've searched the web and I didn't find anything that could help, I also searched this site but there are only a few things about sound problems. I think the problem is caused because Linux is not detecting my sound card (its an on board sound card) or maybe I have not given the command to detect it/activate it. In Google I've found that 'lsmod' and 'lspci' commands are for detecting drivers, so I executed those in my terminal and put them here, I hope this might help fixing my problem.

Gonna reinstall it, things usually go better the second time.
make sure u have adding the user to audio group in order to access sound device.
gpasswd -a user audio
Yes, I think that was the problem. Anyways, I reinstalled Arch Linux and everything is working fine now.

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:
Bus 002 Device 004: ID 0d8c:0105 C-Media Electronics, Inc.

Bus 001 Device 001: ID 1d6b:0002
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:
generic-usb 0003:0D8C:0105.0004: input,hidraw3: USB HID v1.00 Device [C-Media Electronics Inc. USB Audio Device] on usb-0000:00:0b.0-5/input3

cannot create card instance 0
snd-usb-audio: probe of 2-5:1.0 failed with error -5

As you can see, I get three different errors. I've googled all of these, but have come to no conclusion as to what they mean, or a solution to them.
Any helps much appreciated,
Alex

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.

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.

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?

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.

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.

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.

MacBook Pro USB Audio Device Issues

Hello,
I am currently using a MacBook Pro 2012 model and I am having trouble with connecting an audio import source via USB cable. The device I am trying to connect is a pair of Astro A40 headset with the MixAmp. According to various sources, the amp needs to be plugged in into a USB port. I have seen this done and when they go to System Preferences > Sound the device is shown. Unfortunately, I follow the same procedure as the one found on various sites and my computer is not recognizing that anything has been plugged in. I have tried both USB ports and nothing seems to be working.
Anyone ever hear anything about the newest model of MacBook having troubles with detecting audio devices via USB ports? Any help would be greatly appreciated.
Thanks,
Michael

So far as the Go Pro connectivity, it was an issue on the Go Pro end. In order for the Go Pro to be found, I needed to remove all accesories. iPhoto still does not pick it up, although Finder did.
Flash Drives still not found.
Odd as I remember I used to be able to just plug in a device that had anything to do with pictures or videos and iPhoto would just automatically detect it and ask to import.
