OS X Mavericks :: USB Port Digital Sound Control
Jun 29, 2014
Having just migrated from 10.6.8 where this problem didn't exist, I don't know where or what might be causing this in 10.9.3.Â
I run the JRivers music program Media Center and the normal player feeds the digital stream out the usb port to my DAC. It has 2 modes, starting up with exclusive access and not starting with exclusive access. I have tried it both ways with identical results.Â
If I run music thru the JRivers app and out the usb and then stop the player to have a browser (safari or firefox) play a video, the audio portion of the browser audio is sent to the front panel speaker and not to the usb port.
This wasn't the case with 10.6.8 where I would switch back and forth frequently. Now I have to restart the mac in order to 'release' the usb port back to the browser.
That is until I run the Media Center over usb.Â
I have run Audio Midi Setup, to see if I can 'release' the usb port, to no avail.Â

I have a G4 400mhz and 10.3.9
I recently used a usb CF card reader and mistakenly yanked the cable out before 'ejecting' it.
Now my two trusty canon digital cameras (which I reliably connect directly to the usb ports - no card reader needed) are not recognized.

I have a macbook 2.16ghz bought in June 07. Im wanting to buy a western digital 320gb external drive, which is supposed to be powered by the usb port. I read somewhere it takes 600 MA to power it, and someone said it took 1000MA to power it. In system profiler it says my macbook's usb supports 500MA, which really surprised me since its a pretty new computer. My question is if anyone has a 320gb passport drive on the same generation macbook i have that works. Or if you need a y cable to do it.

Can you plug a digital camera into the TC's USB port and upload photos? I tried plugging it in but the camera didn't show up anywhere. Can anyone confirm if this is possible or not?

I finally upgraded from my 15" PowerBook 1.67 to the new 13" MacBook Pro 2.66. On the PowerBook I would usually run an external display using a single link DVI cable. I have read about the issues with the apple mini display adapters not working on DVI-I or non fully digital displays, but since I had been running the external via single link DVI (digital correct?) I figured that I wouldn't run into any problems. I did some troubleshooting with what I had and plugged my computer into my TV through the mini display adapter to a single link DVI to HDMI cable and all worked fine. Do you think that a dual link DVI cable could solve the problem connecting to my monitor? Or is my monitor flat out incabable? Third party adapter? Worst case I could just go VGA, though I don't want to. My monitor is a Sceptre x20.

My wife has a MacBook and there is no firewire port. We are trying to capture video from our Sony Handycam mini DV camcorder but without the firewire port we can't capture the video in I Movie. Is there a way of connecting the Sony camcorder to the Macbook and capturing the video?

Upgraded to 10.5.3 and suddenly my digital out is no longer working. It'll play fine out of the internal speakers, but nothing at all coming from the digital optical out. Any chance someone with an older Mac Pro could test their digital out for sound?

I have the new 2012 Macbook Air 13''. I had heard there would be an infrared port so I can use my Mac remote control. I cannot confirm. Is this part of the 2012 Macbook Air?

the mac boots very slowly recently, but it went faster a month ago. I use Command+V to boot in verbose mode, it displays "[Icannot get audit control port", and then blocks. After waiting for about one minute, it goes on for Ethernet detection, etc. The "one-minute" bothered me a lot. Probably it's a hardware issue or not? Do anyone know what's it, and how to fix it?I have a MBP 2010-13#model, installed with Lion OS.

My MacBook Pro seems stuck on digital output thus no sound from speakers. Headphones recognized and work but internal speakers don't revert to default or even show up as a sound option in System Preferences. Any way to get internal speakers back? Restarting computer did not do it.

The speaker on the top of my screen is muted and I cannot get any sound out of the internal speakers. When I try to raise or lower the volume there is a circle with a line through it underneadth the speaker level window that pops up and everything seems frozen. I've checked online to find a solution and did see a red light in the headphone jack. So I plugged back in headphones and a USB and pulled out the headphones, the red light went off but I still see no option for internal speakers in my Sound preferences. What do I do? I'm trying to avoid a trip to the apple store...

It was very hard to come up with a title for this thread. But here is the problem: I have 5.1 speakers i used for my PC, Logi z680s. I plugged in an optical cable to them and the PM. The volume control doesnt seem to be synced at all to what is going on. So I can have the main volume all the way down and as long as there is volume in itunes up(not set to mute equivalent) and up on the speakers, there is sound coming out. If I use the speaker out cable(which only allows 2.1), the sound is "synced" so even if I have sound on the itunes up and the speakers, if I lower the volume all the way with the main controls, the sound will go off. How can I force the optical out to play nice and sync with my volume control?
I think its worth noting I went into sound options, selected the optical out(when it was plugged in), and muted internal speaker but that didn't solve anything. I also know if I have the speaker volume set low enough to begin with, I can turn the volume down enough in OS X to make it seem mute. But needless to say that requires me manually messing with the speakers anytime I want anything over a whisper, so I can't really call that a solution.

I have a MacBook Air, and the sound is not working. The sound bar is full but there is a stop sign like the one when you completely turn off the sound. And I cannot control the sound bar, It is stuck like that.

I recently came across a Mid-2009 15" MBP with 10.6 on it. I couldn't control the audio, but I figured that when I formatted it and put 10.7.3 on, that issue would go away. Unfortunately I was very wrong. I've been investigating the issue and I've tried just about every permissions fix under the sun, and still to no avail. So far, I haven't reinstalled the OS, but I doubt that would work as it was an issue when 10.6 was running, and I did a complete reformat before reinstalling.Â
Startup chime works fine, and the speakers are recognized in the audio panel as well as the MIDI utility. I just have no control over the sound, and I never have. Plugging in peripherals doesn't work either, this one has really stumped me. Â
I've changed the root .plist files, and I've tried repairing permissions half a dozen times but still nothing has worked. I'm trying to look for a new angle on this issue, because permissions don't seem to be panning out - unless there's something big that I missed.

OS X Lion, output: Cinema Display. Volume doesn't change by control keys on keyboard. But it does with software volume control (on iTunes, for example). When I press control buttons on keyboard, volume icon on display appears and changes - but not the volume. It lets me know that buttons are working, and Mac recognizes that.

since a few weeks, we regularly experience that the sound volume control does not show up in the screen title bar, and we cannot play music in iTunes or in youtube. I don't know if this is since i attached a usb Time machine backup disk or since when i upgraded from 10.7.2 to 10.7.3 The only way out is rebooting and then this works again, The sound volume control is back and i can listen music.Â

My sound output preference is set to mute and is highlighted in light gray so that the preference can't be changed. Also, simultaneously, the sound control in the toolbar is gone and is replaced with an eject symbol that responds "SuperDrive F12" when clicked on.

I'm looking to buy a second hand Mid-2009 Macbook from eBay. Everything looks great except I have seen that it has a combined audio in/out port. I record a lot of guitar, so how could I plug both my guitar in as well as monitor it through headphones? And if USB audio is the solution, will my playing and monitoring be in sync?

it appears i have an email account that is looking to digitally sign emails on when they are being sent. This causes my email to request access to my keychain every time I send mail. Â
How do you turn this off? Â

An HDMI adapter that splits into USB and MDP so you can get sound into your TV. No word on pricing but I'm extremely excited for this!

Recently I have noticed that I cannot get any sound from my mini display port when conencted to a TV. It did used to work. I get a perfect picture everytime but no sound. I've tested the mini-display port to HDMI cable on another mac and it works fine. I've bought another Moshi mini display port to HDMI connector and that also does not work. I tried this on 3 TV's and its all the same, picture but no sound. The HDMI option does not appear under system prefs, sound & output. The only options are internal speakers and soundflower 2ch & 16ch. I've tried uninstalling airfoil and still the same. I can't recall when it stopped working. I did attempt to install OS Lion but it crashed my mail so I restored to 10.6 through time machine. Â
17" MBP. 2.8 intel . 8 GB ram. 256 GB crucial flash drive. OS X 10.6.8. Think it is 2010 model.
