MacBook Pro :: To Sony Lcd Via Dvi / Getting Audio Noise Through Tv Speakers
Oct 22, 2007
I'm connecting my mbp to my new lcd sony bravia via dvi to hdmi lead and then connecting the sound via headphone jack to tv's 2 x phono, however i'm getting lots of audio noise bleeding through tv speakers underneath the main audio feed, i'm certain that its not a dodgy lead as iv'e tried 3 of them, however if i unplug the dvi lead the noise goes away, is it possible that the hdmi input is conflicting with the phono connection somehow.

I am trying to hook up the digital audio output on my cable box to the digital in on my dual 2.0 G5 running 10.4.9, 1 gig RAM. I have HDMI and component video out to monitor, but I use JBL creature speakers and sub for audio.
I have the propper cables and routing, sounds prefs set to digital in, and line out, to go to JBL creatures and first I get no sound at all. If I start AudioHijack and use same input and output settings all I can get is a hissing/clicking sort of sound. Same with using Soundsource and LineIn.
Audio MIDI Setup only shows or giveds me Built-in Audio for selections under system settings and properties for. Ausio Input and output show Master stream grayed out and I selected digital in and Line out for my sources and no change. Both ar set to 441000.0 Hz 2ch-24bit as well.

Dual 2.0 G5

Situation: no sound out from speakers in admin and user account and newly created account. Headphones work, startup chimes work on speakers.
Go to Sound in Preferences and only shows Digital Out for output. Should show Internal Speakers. Ran Diskwarrior and Applejack and zapped pram. Took mac apart and confirmed speakers wired correctly which is verified by the start up chimes being audible on the internal speakers. tested all accounts and created new account all with the same results. Did search of Google and MacRumor. Found one unaswered post indicating same problem. Had same problem with another macbook pro, ran same steps, take apart, confirm wiring setup, Diskwarriored, applejacked and zapped pram and it fixed the problem. I'm not sure what else to try. Did check Audio Midi Setup util and it also did not see the internal speakers.

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...

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

Well i'm progressing with my connecting the Mac to the TV... Have the video going fine with the Mini DVI to HDMI but for the life of me I can't get the audio output going. I have the 3.5mm RCA jack cable in the output from the Mac and the computer has recognized that it's plugged in and comes up at headphones. Now the problem is getting the TV recognize the audio input.Â
I've read elsewhere that there should be a way to set the TV to allow a video HDMI input along with an analouge audio signal.Â

I recently got a brand new 17' unibody MacBook Pro. Although it was brand new, there have been a flare ups. The last time I had the problem, (note: it is always while watching a YouTube video) this is what I captured before quickly closing the window. http://grab.by/1Gjt
That was New Years day. The first time I experienced this problem, I got nothing on the YouTube player and while skipping throughout the video to get it to stream, a noise that can't even be explained screamed out of the computers speakers. Today, I just had the same problem. I have no clue what it is except that I do know it comes from the speakers. Could anyone elaborate on if something similar has happened to you?

Yesterday my speakers stopped working. It's not software based, the audio drivers are working properly. Whenever a sound that is over a certain volume is played, you can hear a pop come from the speakers. For instance, if I play a song that has fluctuating volume, every time the volume goes up, there's a pop, and every time it goes back down, there's a pop. The volume the computer is set to doesn't effect this. Even if it's muted, there's still a pop that's the same volume as if the volume is turned up all the way. Any ideas what could be causing this?

I have a Macbook Pro MC666ll/a. It is a core i7 15" with the AG screen. The issue I am experiencing is a random static noise coming from my speakers every now and then. If i have external speakers plugged in then the sound comes from the external speakers. Is this normal?

Today, my mac freaked out on me twice. I was watching something via Quicktime and all of the sudden the screen went black and green and started going crazy like it was twitching or something. And I got this loud noise coming out of my speakers. My MacBook is about 3-4 years old.

I want to disable audio output on my MBP, either entirely or just disable the built-in speakers. I don't want to mute it and be able to raise the volume and it'll start working again; I want there to be no possibility of sound unless I go back and fix what I changed. I know this sounds weird, but does anyone know how to do this?

Just got my 15 LED SR Macbook Pro. When I plug my bose speakers in at my desk and listen to itunes, I am getting a static pop sound. Should I take it back or is it fixable? By the way, LG panel and no yellow 1/3 of screen. Initially thought it was yellow, but I calibrated it, and now it only looks yellow if viewed from the side. Head on, white. One thing I have noticed, when I watch movies on it in the dark with the brightness turned down (cause this thing is a torch), I am getting quick flashes when a screen has high contrast light and dark. I am very sensative to LCD flat panel TVs that use a colorwheel. Like a JVC dilila, I see rainbows! Is that normal for an led flat panel to see "quick white flashes of light"?

This only happens occasionally, but sometimes when I have my speakers plugged into my 2010 macbook pro, the sound just dies. If I unplug the speakers the sound comes through the built in speakers, but the only way for me to get the jack to work again is by restarting my computer.
Has anyone else experienced this? Is it a hardware or a software issue?

I recently obtained a Mac mini to use with my Sony LCD projection television (model number KDF-E55A20). To connect the two, I used a standard DVI to HDMI conversion cable. The picture looks great. I have connected the standard audio output of the mini to the audio portion of the HDMI port (#6) on the television using a cable that changes from the audio-out to RCA (red and white) cables. (I'm sorry I don't know what the name of this sort of cable is, but I know it is very standard).
The problem: I get no sound! To troubleshoot I connected my Powerbook G4 to the same HDMI port (using the provided adapter to connect to the same DVI to HDMI cable). Once I plug in the same audio cable as I tried to use with my mini, I get both picture and sound. It seems that the television inactivates the audio input component of the HDMI port if it picks up what it thinks is an HDMI input (since it is supposed to carry audio). But it is only getting DVI! So the problem is not with the mini as it produces audio normally. There's a setting (hopefully not hard-wired) with the Sony to inactivate the audio-in on HDMI input.

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 a Macbook Pro and something happened to the audio jack recently. Not sure what but I have a 3 year old and pc husband at home. Basically the inside of the jack went from being an inny - where you can plug in an audio plug, to an outie - where you can only insert about half of your plug and it won't go in any further. When I go into Sound settings - Output it says the selected device has no controls, and the speaker icon on my status bar is greyed out. I brought it in and they said they would need to replace the logic board in order to fix the jack - $1,000.... yikes.
So long story short I am wondering if it is just the audio jack then could I buy usb speakers and use those instead? Any work around at all? I wish there were a way to just tell the computer to ignore anything the audio jack was telling it, but I was told that is not an option either.

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.

Speakers pop/click and then audio goes in and out while watching videos. This has happened on and off for a few years, and seems to be pretty random. I'll be watching a video on youtube and this popping sound will happen sporadically, and audio will mute, come back, switch from headphones to built in speakers, back and forth, maybe even staying muted for a few mins. Â I have a 15" MacBook Pro circa 2010.

The speakers on my Macbook have suddenly stopped working. If you plug headphones in, fine. In the system preferences, 'built in speakers' are no longer an option for audio output. Just 'digital out'. When I try and change the volume of the speakers, the symbol is greyed out, and there's a little "you can't do this" symbol.

This morning, the speakers on my MacBook Pro (Early '09) stopped working, but the machine transmits through the headphone jack just fine. I've done a PRAM reset, and that hasn't fixed it.

My 15" late 2006 MBP has just stopped producing sound from the internal speakers and for the first time there is a red light visible inside the headpbone output port. Apple support says contact support but since I'm a long time out of even my extended warranty.

I noticed in the past week that when I scroll through a webpage I can hear a clicking sound (similar to the one from the MM) coming out of my speakers? This also seems to happen when I scroll through my iTunes library but in this case it's a humming sound, when the scrolling stops so does the noise. I've tried muting the speakers but the sound is still there, has anyone else experience this before?

Just set up a new Mac Pro (8-core) and plugged in my old M-Audio powered speakers (about 10yrs old but still going strong!). I use a mini-jack splitter cable that outputs stereo RCA to the speakers, plugged into the speaker port on the nMP. There is a constant, low hum coming out of one of the speakers; it sounds a little like CPU noise and it is NOT affected by volume settings from the Mac or the speaker knob. It's the right-side speaker which is unpowered, connected to the left unit via speaker wire (the left unit has the power switch and audio inputs and is not affected.)Â
I've tried moving the speaker wire up and away from power cables (two Dell monitors directly next to the speakers) but that doesn't work; it doesn't sound quite like a DC hum anyway though. The speakers aren't heavily shielded (they usually pick up interference from an iPhone placed too close) so maybe it's always going to be an issue. I used to have them plugged into a 2006 Mac Pro via an analog mixer which I've removed from the chain.

I recently got my MBP and I noticed there's a issue with headphone audio distortion. When I plug in my earphone or headphone without any sound playing, there's a clear whining noise like zi zi zi sound which is really clear, sounds like old 80s radio noise. When I play the music, of course it was covered by the sound of music but it really bugs me out knowing that I cannot listen the pure sound of my music. The volume of this distortion noise would not change while I turn up or down the volume of my MBP. I asked someone professional, he said it's a famous issue of screen frequency disturbing audio in macbook pro.

I was listening to my headphones through my new MacBook Pro this afternoon and an electronic noise started coming through. I am using an external monitor with my computer closed, this sound decreases when I put my hand on top of the closed laptop.
