OS X :: Audio Hum From Macbook Pro Only With External Cable?
Dec 11, 2009
I have a macbook pro running Mac OS X 10.6.2I have tried a variety of cables (3.5mm to 2x Phono) to my mixer and each time it produces a loud hum.Ive tried the same cable plugged into my iphone direct and its perfectly fine so it was looking like the audio output of the mac, however, when I plug in headphones (ive tried 3 different pairs) i dont hear the humming at all
a Cable that DEF transfers audio over to the tv? Also here is my macbook pro model. Does it do Audio? Build 10FS69. Someone said there is a belkin one, is that right? Also, I just bought one from Monoprice and that f'in cable doesn't work
I have attached my Mac mini to my Sony TV (to use as a moniter) - there hasn't been any trouble with the picture but I cannot get any sound. Â
I am using a VGA (I know that doesn't send audio over) plugged into the 'PC In' port at the back of my tv, and I am using an audio cable with a normal headphone-type jack on one end (going into the headphone port on the back of my mac mini) and the red/white cable going into the HDMI-in red/white ports on the back of my tv. I can't figure out what is going on - I tried plugging the red/white cables into all the input ports on the back of my tv, just in case, but no luck.Â
Is there a way to output Audio to a USB cable from a 2008 MacBook pro? I have a stero that has an input for USB sound and Am wondering if it is possible to send sound via my MacBook to it.
I have a Monoprice USB/Mini-USB to HDMI port in Samsung LCD TV. When watching a movie being shown from my Macbook to the TV screen we can't get audio to transfer to the TV. We've tried different setting on the TV remote but nothing seems to work.
Info: iPhone 3GS, iOS 5, Main syncing computer is MacBook
Do you guys think that Apple would release a firmware update for the Mini Display port so that it can send both Audio and Video through a single cable on a late 2009 13" MBP? They have done it on the New MBP but yeah it sucks to connect/carry 2 cables all the time on my MBP I bought in Oct 2009
Trying to figure out if something is up with mine and a buddies machine specifically or they are all buggered....
Please post if you have an audio pop or click type sound that is intermittent (every few minutes or couple hours) on your i5 or i7 machine while playing audio through external speakers.
If you have it, please describe your situation as it occurs so we can perhaps isolate it:
I.e. Plugged in / on battery, programs running, usb plugged in, etc.
Mine happens whether on battery or not, iTunes, games, movies, Locked in video card...
Would a standard 3.5mm audio input cable work? Would it fit in the port on my MacBook Pro? These are the cables I am looking at: [URL]. Port Image. I am looking at recording music from my Record Player to my computer with this Tutorial: [URL].
My iMac 24" (3.06 GHz Core 2 Duo, 4 GB memory, one of the newest generations) has an audio out jack that double as an analog/digital out? I have a high end sound system with receiver, sub, speakers, surround, etc. that I want to deliver the highest quality sound I can from my iMac. I use optical cables with my other peripherals yet I was unaware that there was a converter that could take an optical signal to an analog "headphone" jack? This doesn't reduce the quality at all? Could someone tell me the exact name of such a converter and if I'm correct in assuming it allows a standard optical fiber audio cable to fit in the "headphone" jack on my iMac. Would like to run out and grab one. And again, is this the best option for highest quality audio from my iMac?
I hook up a Samsung LCD to my MBA via the Mini DVI cable and everything works great. However, when I unhook the cable (regardless of whether the Mac is on/off), the Mac doesn't pick up that it is now only on a single display, when opening apps (say Firefox), and opens them as if they were on the secondary monitor (so I can only see the very left hand edge). I can't imagine that I would need to minimize or drag the window to the MBA display prior to unplugging the cable, every single time...?
The only work around I have been able to find is drop the display resolution to 8x6 and grab the edge of the window and drag it over. I've tried "Detect Displays", restarting and other "tinkering" to no avail.
How can i connect macbook air (current model) to a external display? I have a view sonic display that claims to be mac compatible. It came with a USB cable. But when i hook it up, it shows no activity. In system preference, i hit detect display, doesn't seem to do anything.
In a few months I will be setting up a booth at a comic convention and I would like to have two monitors running on the table to showcase the art. I have a 17" MBP Unibody with one external 24" monitor via the mini-DV - DVI cable. I would like to attach another 24" as well. These two monitors only have to mirror what I am doing on the screen so I just need a cheap solution.
I have a presentation tomorrow and need to hook up my MBP to the projector in class. I bought an Apple Mini Displayport to DVI cable, and a DVI to DVI cable. I thought this would be the case, but come to find out the system does not support DVI. So I had to run to Best buy to get a DVI to VGA cable. I tried out the MDP > DVI > VGA rig on my external monitor and got nothing. The screen on my MBP responded by turning blue for a second and then back to normal...but the monitor said "No Signal". Is this some jargon with DVI-D and DVI-I? I need to know by tomorrow morning if I have to run back to the Apple Store and get a Mini Displayport to VGA cable.
Just wondering if anyone knows is the original iBook G3 Clamshell A/V cable is interchangable with the iPod A/V cables?As in, can I use an iPod AV cable for my clamshell to output to my television?
Looking for best conversion cable to hook my Mac Book Pro up to our new HDTV - thought someone said I should get a converter that converts Mac 800 firewire output to an HDMI cable hookup.
When I attempt to use iphone ear buds, there's no sound from them - audio only internal. I should be able to select external audio source, but it's not in the list in preferences. i checked About this Mac / Audio, and it's there.
I have just read a ton of forum posts and want to make sure I am going to buy the right accessories to make my new Mac Mini all it needs to be to run my home theater.1. For 5.1 audio, do I need to buy this product and then just use a standard Optical audio cable to plug into my receiver?2. The new Mac Mini comes with a mini DVI to DVI connector correct? So all I will have to buy is a DVI to HDMI cable?3. Is OWC (other world computing) the best place to buy upgrades for the mac mini? I have looked at the videos on youtube and it seems like something I should be able to do no problem.
With a sharp fingernail I seem to have damages the internal ribbon cable that connects the audio card in my 2009 Mac Mini, and am looking to source a replacement, preferably in the EU. I'm currently in the UK.The part number is 922-8809.
A Google search reveals a few parts suppliers in Europeland, but they are all charging silly prices for the cable, and US suppliers impose ridiculously high postage charges.
I am trying to connect my MacBook Pro (4 yrs old) to an external monitor via HDMI. I am mirroring the display and video works fine. Sound won't play thru thru the TV, only thru the laptop speakers.
Info: MacBook Pro (15-inch Early 2008), Mac OS X (10.5.8)
I receive cable TV at home and I am told that instead of using a TV I can hook my MacBook via a HDMI cable and watch TV that way on my laptop screen. I'd like to do that. Is the information correct? How do I go about it? Can my MacBook do that?
The audio on my macbook suddenly stopped working. When I click on the audio adjuster, it won't even let me change the level (the little circle is white now, not blue).
But when I plug in headphones or an external speaker, everything works fine. I can once again adjust the audio and get sound
There was a red light eminating from the audio out jack for a while (last couple of days) but today, there is no longer a red light. Still no audio from the speakers.
I have owned my MacBook Pro since June 2010, and have always used a pair of independently powered (via adapter) external Dell speakers for audio output. Since upgrading to Lion about 1 month ago, I was having intermittent audio issues, which were resolved by re-starting my computer (not ideal but it worked). Today, the speakers just stopped working. The internal speakers work, but when I plug the externals into the headphone port, they don't produce sound. Earbuds in the same port also don't work (but the earbuds are good). The external speakers are being recognized by the sound panel in system preferences.

I want to hook up my new monitor with my 21" Imac. I have bought this mini displayport to dvi adapter. [URL]. What dvi cable should I buy? The adapter is dvid single link, but according to wikipedia the conector is dual link?
I have just acquired a Dell 22' Monitor. I want to hook iy up to my MacBook Pro 15". I know I need a DisplayPort to DVI adapter But what kind of cable to I need? DVI-D Single? DVI-D Dual?
Since I am going to run an external monitor is there a way to make this work with the lid of the MacBook Pro closed?
