Displayport audio vs USB audio
I have pre-Thunderbolt 27 display that is offering my 2011 Mac Mini 2 audio options : Display Port vs USB audio
Now, I beleive if I will have to plug in the USB cable either way, to ge the USB hub, microphone, camera to work.
So I don't believe I can necessarily save the USB port (if I could, then why would there be Thunderbolt?).
What I want to know is there any advantage to using Display Audio over USB ?
- Is the sound any better ?
- When I am using USB networking for other purposes, will Display Audio have less USB bus contention and play better ?
- Similar as above, when playing music over Display Port, will my USB devices be faster due to less contention ?
I am leaning towards Display Port audio unless someone can give a definitive answer
Thanks.
You say 'no', but then why did they add the option on the Mac Mini? ie It wasn't to free the USB connector, as that is still used anyhow for the camera, mic, usb hub and software updates.
Software updates? Not sure what that has to do with this. But anyhow I have a mac pro with a 27" mini-displayport apple display and both options are available too. It has nothing to do with power (I'm certainly not underpowered). It's simply that those ports are available audio out devices.
On my old Macbook Pro, when viewing live video from my Hauppagauge HDPVR via a different USB port on the Mac (not the screen), the sound was sometimes choppy if I was doing other tasks as well.
You machine has its limits in processing power and is probably having trouble using too many processor intensive processes. Use your Activity Monitor to see which processes are using large amounts of cpu time.
The display has a USB hub that chains of the USB port, so if have other devices working like my external USB Bluray drive, then I think there could be contention when using that also when reading/writing.
Contention is managed everywhere; hard drives, usb buss, fireware buss, pci buss, memory buss, and any others I can't think of at the moment. You're splitting hairs worrying about sending audio to usb ports which is a blip on the overall processing of generating that audio in the first place. In other words its the processes and efficiency of your machine that are a bootleneck.
So I am really hoping someone will confirm that the audio data was moved to the mini-display plug to provide more bandwidth via the USB controller, or to guarantee bandwidth for consistent audio.
Good luck with that.

No audio after USB audio accessory is connected
I've discovered what I believe is a rather interesting (and rather serious) bug in the iPhone 2.0 software:
When an USB IAP accessory (such as a lot of newer car stereos) is connected and disconnected a couple of times the audio output from the iPhone will often stop working. Disconnecting the accessory or plugging/unplugging headphones does not fix the problem.
And I mean the audio completely dies: I get no audio from the phone, voicemail, ringtones, iPod, or system sounds from the speaker, headphones, or dock output.
It's like the audio drivers crash. Sometimes the audio will start working again after a long period of time (like if the phone has been sitting idle for hours while I'm at work) but usually I have to reboot to get it working. It seems when I can get audio to work again without a reboot, I get a new crashReporter log about mediaserverd the next time I sync.
The problem occurs when the phone is connected to an iPod accessory that uses the IAP audio-over-USB capability (I tried my Pioneer car stereo and a Kenwood stereo at Best Buy) It does not occur when connected to an accessory that only uses analog audio. I've seen it happen on my iPhone 3G and the original iPhone, so I know it's not a hardware problem.
I know for a fact the Pioneer and Kenwood units I tested are stated as having USB inputs compatible with the iPod Video, iPod Nano, iPod Classic, and iPod touch. (I can confirm the Pioneer does work fine with my old iPod Video.)
Multiple reviews have shown them to also work well with original iPhones running 1.1.4 and below (even if you do get the "not made for iPhone" warning)
However, both phones I tested are running 2.0. Which leads me to think this is a bad 2.0 bug.moved to different forum

I have audio hardware that does audio I/O with the Mac through a USB connection.
I have another piece of hardware that does audio I/O with the Mac through a USB connection.
I would like to route the audio out from hardware A to audio in of hardware B, and vice versa. Do you know of an application that would enable this cross connection?Quite possibly I have not described the challenge adequately.
Picture, if you will, an audio tape recorder and a sound system. The out port of the tape recorder is plugged into the in port of the sound system. The out port of the sound system is plugged into the in port of the tape recorder. I'd like to essentially replicate that. For example, suppose that my tape recorder is USB connected - I can play into the Mac, I can record from the Mac. I also have the headset (headphone & microphone combo). I want software that cross connects the two as described above. Once cross-connected, I can record my speech on the tape recorder, and hear the tape recorder play back through my headphones. Now replace the USB tape recorder with a USB-interfaced two-way radio. I speak into the mike, the audio is converted within the mike assembly, the encoded audio is passed into the Mac, transferred to the other USB port where the encoded audio is passed to the radio device, where it is restored to analogue and used to modulate the radio carrier. Similarly, what is heard by the radio is passed to the headphones of the headset.
The software that I am seeking would have the ability to deal with two separate USB inputs and two USB outputs. A mixer probably can deal with two or more discrete inputs, but probably not keep the two inputs isolated and passed to two outputs as required by the application. -
I upgraded to Solaris 11 x86 and Firefox 3.6.10. I have sound through Solaris but not through Firefox or any of the add-ons.
I am using USB speakers which work with Solaris Rythmbox. How can I redirect Firefox audio to my USB speakers?It works fine, thank you. There is one glitch when I turn off my system and on the next day the audio is missing again. Applying the dsp to dsp 0 reboot and then back to dsp1 reboot I get the audio back.
Is there any way to restart the process? -

[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 ! -
Kanex MIni DisplayPort+USB Audio to HDMI Adapter --NO SOUND
Hi,
I just purchased a Kanex Mini DisplayPort+USB Audio to HDMI Adapter for my new Samsung flat screen so I could watch netflix movies. The guy at Tekserve (NYC based authorized dealer) said it's really cool b/c it's audio and video all in one. Two cables are attached to a small box on one side and on the other side of the box is for the HDMI cable which goes to the TV (most of you prpbably already know this) .
The two attached cables fit into the the USB (audio) + mini display port. The video works great, but no sound. I called Apple for tech support and we tried a few things like changing the sound output to USB, but no luck.
I can call Tekserve on Monday, but would love to figure this out before then for the week-end.
Thanks everyone for your help.
MaryThere are actually 2 different Mini Display port to HDMI adapters from Kanex. One supports 2 channel audio through the USB audio out cable, which is the one you have Mary. The other one with the extra audio plug cable supports 5.1 digital audio.

I don't have either of these adapters but I would think that you "should" be able to go into your System Preferences under Sound. If the USB plug from the adapter is plugged into your MacBook, then it should show up in the output window in the Sound preferences which you would then choose instead of outputting the sound to the built-in MacBook speakers.
At the bottom of the product description page of the adapter that you have (the USB 2.0 version), it says this:
+Sound Output setting on Macs must be changed to "USB Sound Device/USB Type" to have the adapter operating correctly.+*
Let us know if you get it working properly. I'm considering getting one also.
Sorry.... I just re-read your initial post and it sounds like you already DID try switching the sound output to USB with no luck. The only other thing I can think of is the adapter might be bad and maybe exchange it for another one from where you purchased it. Or you could maybe exchange it for the 5.1 digital audio out version. Although it sounds like your sound is going directly into the tv via HDMI and not a surround sound receiver.
Kanex does have tech support and contact links on their web page. Maybe you should email them directly about your problem. Unfortunately I'm sure you'll have to wait til sometime during the work week to get a reply back. -
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.
ThanksSure,
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,

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: aynI 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. -
USB audio input to voice-over tool not working

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!

GKapHello 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

I was wondering this, because I want to hook up my 2011 MacBook Pro to a external monitor (TV) using an hdmi cable. This would be heplful before I buy a mini displayport to hdmi adapter, and then maybe find out that the mini displayport might not transfer audio, only video.
Yes, min Displayport supports audio and video for the 2011 MBP 13" via HDMI.

How do I get my MacBook Pro, running OS10.9, to recognize USB audio?
The audio source I'm using is an M-Audio Audiophile USB box.
I tried downloading the driver from here:
http://www.m-audio.com/index.php?do=support&tab=driver&serie_ID=6&PID=41cf7347b2 0eff77b69588578a74aa58&OS=x114#tabs
But when I double-click the executable, it says it won't launch because it's from an "unidentified" developer.
In desperation, I then tried this:
http://download.cnet.com/USB-Audio-ASIO-driver/3000-2120_4-6405.html
But it appears to be designed for Mac OS9, and won't open.
Any ideas? I can't imagine the modern OSX10.9 operating system simply won't support USB audio sources.
Thanks.In the system preferences under the security & privacy section click the Lock icon and type in your password. Then in the section for "Allow Apps downloaded from:" area tick the Anywhere entry. Your app and drivers will now install.

USB Audio Device Not Recognized by Stream 7 tablet
Half the reason I bought the Stream 7 was to use it has a music player with my iBaso D2 USB Audio DAC Headdphone Amp.
The device is recognnized by my Win 8.1 desktop and every other computer I've plugged it into. Why it is not recognized as an audio playback device is beyond me. I've tried all of the suggestions that I've been able to find on the net without any luck. Is therte some reason why this function has been disabled on the Strwea 7?
This question was solved.
View Solution.Problem Solved!
It turned out to be a combination of the usb cable and the OTG USB hub. On my desktop the iBaso was cable specific as to the device being recognized. When I tried the working cable witht the OTG hub on the Stream 7 it failed as usual. But when I tried the cheap monoprice adapter it worked.
The usb audio solves the horrible sound problem with the Stream 7 for anybody who is lookiing for a Fix.
The OTG hub works with a mouse and a mSata drive perfectly but not with the iBAso DAC.
Thanks to everyone who replied for keeping me trying.
