MacBook :: External Sound (Not Red Light Related) Channel Dead
Sep 11, 2010
I have a white 13" MacBook. I'm totally Mac illiterate. I bought the Mac because I just about to dig my eyes out in frustration dealing with MS Vista. I like the MacBook.....but about a year and a half ago, the right channel of my 3.1 speaker setup cut out. It worked fine for the 1/1.5 years of ownership.
Internal speakers? Work just fine. Headphones? Perfect stereo.
External speakers with subwoofer? Right channel is dead.
I've tried max laptop volume and creeping volume on the actual speaker up. I've tried max external speaker volume and creeping the Mac volume up. I downloaded a ToneTester program. Internal speakers and headphones just fine. 3.1 externals? Right channel dead. I don't have the red-light jack issue. My Sound Output toggles between Headphones and Internal Speakers output perfectly. About 7 months ago while putzing with all the settings, I got it all back out-of-the-blue. Perfect stereo with subwoofer. I had it for about 2 months and then poof - right channel faded again.

This started happening randomly earlier tonight, and I haven't managed to find a fix just yet.I was encoding a video file for quite awhile (I don't think that parts important, but I thought I'd include it anyway) and then I tried to play a youtube video. I noticed there was no sound, so I tried to up the volume using the Volume Up key on the keyboard. The volume visualisation appeared on the screen like normal (albeit a bit laggy), but the sound still didn't change, neither did I get the usual 'click' noise you get when you change the volume.I went looking into the sound options in the system prefs. only to find that the Output Sound device was headphones. For a test I plugged in some headphones to see what happened and, low and behold, the Output Sound device changed to the Internal Sound and my speakers were working again, but only with the headphones plugged in.

I have a Blu-ray file (one I own and wanted on hdd for easy transport) on my computer. I want it to play on my Xbox 360 and it won't because it has 5.1 surround sound. Inside the file is the 2.0 audio track separate with instructions on how to merge/change it using a program called Yamb. The only problem is that it's Windows only. Do any of you know a program (preferably free) that can do this for Mac?
I have Toast Titanium 10 and toyed with it for awhile but couldn't figure it out.

When I start importing video into iMovie '06 from my DV camcorder, the sound changes to one channel only (I know the audio on the tape is stereo), and stays that way perpetually, even after I quit iMovie, restart, zap the PRAM, and even do an "Archive and Install". I had to do an "Erase and Install" for it to return to two channels. But the second I start importing video in iMovie, it's back to one channel. I checked the Sound control panel and Audio MIDI Setup, and everything looks fine.

I went upstairs last night to find my Macbook Pro's charger had no light lit up on it. I tried everything including changing wall sockets, resetting the SMC, with and without the battery - nothing! I then noticed I could feel the electrical current on my Macbook Pro and then it started, a loud ticking coming from the brick. It's dead. It's just under 18 months old. Apple has said that I have no Applecare, no tech support and no warranty so buy a new one. I thought electronics HAD to have a 2-year warranty on them in Europe? Can I take that to apple? It's �60 for a new one and things like this shouldn't fail after just 17 months.
It's the old 85W type. The guy at Apple told me they only do the "new" 60W types. Can I use these with a June '08 Macbook Pro? I've had no end of problems with my MBP. I may call an end to Apple - I'm not happy paying over the odds for this Macbook less than 18 months ago for it to have had so many problems already.

is there a sound card out there for a Mac Pro that supports 6 channel direct and digital optical? I know the current Mac Pros already support that but not 6 channel direct. !

I know many say that the sheer volume of 16gb outweighs the speed difference between the two channel settings, but I'm wondering how 32-bit programs (mostly audio applications) will address the RAM best?

My faithful and trusted Intel Mac mini 1.83 C2D that I bought new in December 2007 suddenly died during a major 10.6.3 update install. It almost completed the update and the screen went black and the light went off instantly. The power button doesn't respond at all. I had major work projects going on Sunday night when I took a break, quit all applications and did the software update and it died. I took it to the Apple Store Monday morning thinking it was the power supply. I was informed that the logic board is dead and my HD has to be wiped and OS X reinstalled. The repair would cost well over $300 and have a 90 day warranty with the same logic board installed that could fail again. Ironically enough, I had been thinking about buying another new Mac mini and a new Mac mini Server for work. That's not going to happen now. I left the Apple store with my new $600 paper weight for my desk. What would you do? This was a sad day in my faith in Apple products. Apple Mac mini lemon? While my 500Mhz Cube serves me very well day to day at work, I do need my 10.6 Mac mini to run iMovie '09 to put together my videos for [URL]

My mums macbook has gone crazy! There is no sound coming from the macbook, and when I went to check if the volume was up the volume box popped up as usual but with a symbol, similar to a no entry sign. Circle with a cross through it. Then I saw a bright red light from within the audio jack itself. When I plugged in ear phones it works fine but the built in speakers are not working.

I was just listening to some music through some speakers on my old 1.8ghz cd macbook and then I unplugged the cable from the headphone jack and noticed that there was a red glowing light coming from the headphone jack. Now my sound is messed up, sound works properly only when something is plugged into the headphone jack. Nothing will play through the internal speakers when I try to adjust the volume with nothing plugged in I get this.

The sound doesn't work! I turned on my laptop and there is no sound. When I press the up and down volume buttons, it's normal, but there is no noise. Also, there ISN'T a red light in my headphone jack.

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...

I am trying to connect through iTunes with my Airport Express. No matter how I configure (and the green light is on) no sound comes from the speakers from iTunes even though the song is playing. I can, however, connect through my Airfoil app which leads me to think that the problem is in the Itunes app itself.

My main computer is a MPB17 with 256gb SSD and 750gb HD in an optibay. I have huge media libraries and like to have ready access to all my photos and videos. I have a Gen 1 Air that I use at home for mail and surfing and I have been using my iPad for mail and web when out. I have a max spec 11" Air arriving this week. It weighs the same as my iPad with Vaja case so I'm going to take it everywhere and leave the iPad for a reader in bed. Now I'm starting to think I might leave the 17" in my office and sync the 11" Air up and use if when I'm out. Problem is I want a fast, light USB drive to hold my media. Ideally with USB and FW so I can sync it fast with the MBPro.

I've got several drives that have died over the last year or so. I've got six or seven drives hooked up to my iMac that I use for storage, backing up etc, and it seems like one just dies every six months or so. Maybe one a year. What happens is it suddenly doesn't show up on the desktop anymore, and it never stops churning. I try connecting any of these dead drives to another one of our macs, macbook pro, etc, but it behaves the same way.
Is there anything to be done about this? I'm thinking of getting a Drobo system, rather than buying new drives so often. Is there any special software for dealing with drives in a state like this? Or a place you can take them to to see if they can be fixed? (I have all the data backed up, so that's not an issue. I've called the manufacturer (lacie) but I think they're all out of warrantee, though they're only a couple of years old.

All channels are jammed where I live and channel 14 is the one with the less overlapping. It is enabled on my AP but not on my airport card, how can I turn it on? I bought my Mac in Canada but I know live in Japan where channel 14 can be used.

When I plug my MacBook into an external audio source via the headphone-jack using the red and white cables (do not know the technical name), I only receive sound out of one speaker. At first I thought one of my stereo speakers had blown out, but I plugged my computer into another stereo using another cord and it still only plays one speaker. Also, when I plug in any set of headphones I only still receive sound through one speaker (the left one). My computers speakers still work, and when nothing is plugged in it still says under the output type that it's Built-in Output. I also noticed that sometimes (but not every time) when I unplug something from the headphone jack that a red light flashes around two times, but it does not stay lit when there is nothing plugged in.
**Another note: The sound is not in mono in one speaker, it is just like one speaker is turned off.

I upgraded my late '09 13" MBP to 4gb, but one of the sticks apparently died. I'm about to replace it with my old 1gb stick so then I'll have 3gb total ram.
Will this turn off dual channel mode?

I recently purchased a Retina Macbook Pro 15" no more than 3 months ago.
Today I just noticed that whenever I connect my headphones I can hear the left channel clearly but the right channel is a lower volume and distorted.
at first I thought it was the headphones, but have tried various ones and it doesn't seem to be that.
Also, output from the internal speakers sounds fine, same level on both channels and clear

MacBook Pro with Retina display, OS X Mavericks (10.9.4)

When I am in a quiet room, I notice a light humming coming from my macbook pro and also a light vibration on the right side. Is this just the hd spinning or something to be concerned about? it is 2 weeks old.
