Multiple USB Audio Outputs?

Is it possible to set up the mac mini to have multiple USB audio out puts? I'm wanting to use a mini displayport + usb audio > hdmi cable to a plasma for computer use. But is I want to listen to just plain music use USB audio to a DAC into a 2 channel system. So for this system I would need to use 2 USB outputs for music.
Thanks

Sure,
You can output sound through more than one little external USB sound card, but probably not to more than one at a time. You'll have to select the Output in the Sound Preferences each time to switch them, too.
But don't overlook the Mini's internal sound output as one of your 2-channel or 5.1 audio outputs. The 2009 Mini has better audio output than the PPC Mini, that I also had and used an external USB sound card with (M-Audio Transit). Of course, now there are cheap little external USB sound cards that look like a little thumb drive for an added 2-channel audio output. So, I'd use the Mini's internal output and an Optical cable for 5.1 sound out, if I were going to use one of those cheap little sound cards. But you can go the other way, too, if you want, with a better USB dongle (like the M-Audio Transit) for your 5.1 sound.
Please let us all hear how it goes and what path works for your application.
Peace to you,
C. Livingstone

    You can output audio thru HDMI, with appropriate adapter.
    You can use additional cheap external usb audio for monitoring.

    Is there a USB Audio output device I can get for the Intel Mac Mini, that works in both Mac OS X and Windows XP Home?

  • IPhone 4 USB Audio output?

    I'd like to know when/if the iPhone 4 will offer USB audio output (digitally). I'd like to use a USB DAC without having to pay ~$600 for a Cypher Labs Algorhythm Solo. I'm not asking for power, as my DAC has its own battery. Is it about money for licensing? The CLAS works...why not a FiiO E17 via the iPad CCK? Android has USB host capability...

    Speculation and rumors are forbidden by the terms of service. The phone doesn't support it. Apple has made no announcement of such a feature or the intent to implement such a feature. Your question can not be answered. There are plenty of cheap docking speakers, alarm clocks, etc. that use audio out from the dock. It's not a matter of money. The system you refer to is expensive because the manufacturer feels they can charge that much and get away with it.

  • Losing USB audio output after a time

    I have an external DAC connected to my iMac via USB (direct not via hub) and Toslink Optical.
    In System Preferences > Sound > Output, the DAC shows up correctly, as also it does in Audio Midi Setup > Audio Devices > Output.
    Also, the 'Built-in Output' (Optical) shows up correctly.
    I can switch between USB or optical input on the DAC and they both work fine.
    However, peridocally, the USB output from the iMac will simply stop working: aside no sound, the 'lock' light on the DAC goes off.
    The USB settings remain in prefs/midi panes, and the USB DAC device remains shown correctly (and the format etc. can continue to be adjusted).
    The optical output is not affected and continues to work normally, so switching the DAC to that gives me sound back.
    Unplugging and replugging the USB connection 'restores' the USB sound.
    Any ideas what's getting lost/corrupted here?
    (I'm on 10.8.4 despite the signature)

  • USB devices for audio output

    for five or six years, I have been using an EDIROL device for outputting from the USB port to a standard stereo amplifier.
    I like it - it's good - I would recommend it.
    But I was just wondering what other USB audio output doo-dads might be out there? Surely something good has been invented since 2003.
    Is there a wrap-up out there, possibly done by one of the Mac magazines or blogs or whatever?
    thanks!

  • USB audio out of phase

    I'm having a strange problem with the USB audio output of my PowerBook. The left and right channels are out of phase, both on my USB speakers and my USB headset. The analog output from the headphone jack is fine.
    The problem seems to have arisen some time around my 10.4.9 or 10.4.10 upgrade, although I can't be sure that it's related. It's still happening in 10.4.11. I suspected something strange when Skype stopped working with my headset, but it took me a lot of thinking and a tone generator to determine what the problem was. Now I'm just about positive that all USB audio output is phase reversed between left and right.
    Has anyone heard of this? I couldn't find anything in the forums. Thanks for any help you can provide.

    You may need to verify the Hd & Repair from another volume, HD, Mac, or Install CD/DVD if necessary.
    Then Repair Permissions... trouble is if you don't do this step before & after every update, you can't be assured of every file in the update/upgrade being replaced/updated, it may require reapplying a big Combo update afterwards, or even an Archive & Install after everything is fixed otherwise, personally, I use Applejack...
    http://www.versiontracker.com/dyn/moreinfo/macosx/19596
    After installing, reboot holding down CMD+s, then when the prompt shows, type in...
    applejack AUTO
    Then let it do all 5 of it's things.
    At least it'll eliminate some questions if it doesn't fix it.
    The 5 things it does are...
    Correct any Disk problems.
    Repair Permissions.
    Clear out Cache Files.
    Repair/check several plist files.
    Dump the VM files for a fresh start.

  • USB Audio stopped working on 27" ACD after software update 1.0

    Hi all,
    My 27" ACD worked flawlessly until I installed 27-inch LED Cinema Display Software Update 1.0 earlier tonight. I have a unibody MacBook Pro that doesn't output audio from the mini displayport, when I got the ACD Friday, USB audio output worked fine. I also have a 24" ACD and audio worked fine on that as well. But after software update 1.0, I can no longer get audio output of the 27" ACD to work via USB, I even rebooted my Mac and it still doesn't work. After trying it a few times in Sound.prefPane, I now can't even select the "Display Audio - USB" option (when I click on it it reverts to the other option right away).
    From /var/log/system.log, I believe this is the error related error message:
    System Preferences[332]: Error ^P trying to set sOut device to 264
    Message was edited by: ayn

    I have this problem too. I have the 27-inch LED cinema display connected to my Mac Pro 1,1 via the Radeon 5770. I also suspected it had something to do with the machine going to sleep, but the audio doesn't disappear every time it goes to sleep. Unplugging the monitor fixes the problem.
    I also noticed that when the sound has went away, if I try to change the volume there will be a long delay before seeing the volume-change graphic. Also, toggling the sound device in System Preferences while the problem is in effect is unresponsive, sometimes giving the beach ball. Finally, this message is seen in console logs when the sound has went away:
    10/19/10 6:01:22 PM kernel USBF: 75053.200 AppleUSBEHCI[0xf3d0800]::Found a transaction which hasn't moved in 5 seconds on bus 0xfd, timing out! (Addr: 5, EP: 0)
    I can make this message appear on demand by attempting to change the volume.
    If (when) this happens again, I'm calling support.

  • Multiple usb mics?

    i'm looking to do some home recording and i was wondering if anyone knows if garageband 3 will support multiple usb audio devices? ideally, i'd like to plug in two samson usb condenser mics and record simultaneous vocal and acoustic guitar tracks.
    keep in mind these will be plugged in directly -- i know there are some issues with hubs, so i'll avoid that route . . .
    thanks!

    You can do that, all you have to do is create an "aggragate device" in the Audio/Midi utility and pick that as the audio source in GB. It will have two channels (the two mics) that you can assign to tracks.

  • M-Audio C400 won't receive any audio output in Mavericks

    Hello
    I recently bought a M-audio C400 and a pair of KRK RoKit RP8 speakers for my studio. But the C400 wont receive ant output signal from my Mac.
    The computer runs OSX Mavericks and have been working with USB audio output before.
    Is this a problem you're aware of or might the hardware suffer from some malfunction?
    Thanks in advance

  • Problem with multiple applications using one audio output

    Hey there, I'm having issues setting up my 5.1 headset seen here (http://www.sharkoon.com/?q=en/content/x-tatic-digital) to work with multiple applications.
    Right now I have audio streaming from a flash video, when I try run "$ speaker-test -c 6" I get the following error:
    speaker-test 1.0.25
    Playback device is default
    Stream parameters are 48000Hz, S16_LE, 6 channels
    Using 16 octaves of pink noise
    ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
    Playback open error: -16,Device or resource busy
    If I try open another application which uses this device, the first application has its sound cut off.
    2 more things to note:
    - My preference for setup would be audio output through S/PDIF and input through USB, with the USB output disabled (To not waste system resources).
    - I unmuted all channels in ALSA, however when I ran the test only 2 channels seemed to be working (Front L&R), it may have been defaulting to the USB connection, in which case, that explains only 2 channels being in use, is there a method of setting the S/PDIF as default system wide?
    Thanks in advance for any help given!

    Woops, I guess my paste messed up, new .asoundrc: http://pastie.org/3706033
    I can run both at the same time, however I cannot hear any audio. Do I somehow have to change the default device, if so how can I do that?
    Edit:
    Restarted system now I get:
    speaker-test 1.0.25

    (That's with both commands)
    EDIT 2:
    Interesting, apparently 2 audio streams are working, however the console thing still doesn't work..?
    EDIT 3:
    Didn't last long, now flash crashes and html 5 doesn't work -.-
    EDIT 4:
    Flash only works when other audio is active, however it has constant popping sound. I went through the system logs to get the errors of when flash crashes, it's audio crashing it, here's the error:

  • Multiple Audio Outputs

    First off before I get to the point...
    I would have submitted this through the iTunes feature request form, but it's been removed. "iTunes feedback" is now simply "what would you like to buy".
    Anyway... I've got two audio outputs on my system - built in audio which goes to the internal speakers, and USB audio which goes to some better external speakers. I'd like to use the internal ones for regular stuff, and the external ones for "real" audio apps.
    Most "real" audio apps are smart enough to detect external speakers, and let you select them explicitly, while non-audio apps just use the default, so it works fine...
    Except iTunes doesn't support this.
    Why can't I explicity select the Audio ouput I want to use. It's not a security/copyright thing, as I can already output to the device by setting it as the default output.
    iTunes should spot multiple audio out devices, and pop them up in the Computer/airtunes button.
    (actually Airtunes SHOULD be a regular audio device, and then this would all work as it should, but that's a different argument, which I'm not going to win).

    You can select your sound outputs using system preferences. select sound , select device output.
    or you can go into utilities and open audio midi setup and choose your system output.
    Hope this helps:)

  • How do I use the USB port on my MBP for audio output

    I am a fairly new commercial sound provider running live sound and the occassional itunes type playback at events.  I currently use a Y cable from the headphone output of my MBP osX  into the RCA inputs on my audio mixer.  On an older HP laptop I was able to use a USB output into the USB input of the mixer and the sound was a lot better in quality. I wish to do the same using the new MBP but when I plugged into the right side USB port I received no audio output.  What am I doing wrong?  Thanks howardfrom nh.

    Have you gone into the Sound/Output system preferences to see if your mixer shows up there as a valid output device and if it does selected it there? If it doesn't appear, have you confirmed with the manufacturer of your mixer that it is compatible with Macs and if so asked if there are any drivers you need to install?
    Regards.

  • 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.
