Sound only from left channel

I bout an IPhone 3G for my wife last friday. She complained about the music quality saying that her little cheap MP3 player sounded better. I plugged in the headset and found that there was sound only fro one channel (Left). I plugged my headset from my 3GS and it also only had sound from one channel. Any suggestions?

Try restart, reset, then restore.

If this doesn't help, you may need to make an appointment at the Genius BAr ( Apple Store). The iphone has a one year warranty.

Airport Express: Sound only from left channel

I've got an Airport Express which used to work fine, but at some point in the past few months, I noticed that there was no audio coming from my right speaker when using Airtunes. I've check the cable and it does transmit both left and right when I hook my iPod up to it.
I've also got the low volume problem going on in the left channel that's working. And ideas?

I took the AirPort Express to the Apple Store and it turned out that it was a physcial problem with the hardware. It had to be replaced.

Sound only on left channel

Hi,
I'm shooting some video on a JVC GR-DV3 (admittedly old but still does the job!) and am using an Audio Technica ATR 3350, omnidirectional Lavalier condenser microphone as the motors are too noisy for speech using the built-in mics.
When I import the clips into iMovie all the sound is on the left channel, not equally distributed between the two?
Any thoughts or fixes?
JC

I bet the microphone is a mono microphone. When you plug that into a 3.5mm stereo microphone input, all sound is "sent" to the left channel. You need an adapter cable or adapter socket.

TS1574 Sound only from Left Headphone w/ MacBook Pro

Any external headphone that I use with my 13" Macbook Pro, the sound only comes out of the left headphone. The slider in my System Preferances is in the middle, and the headphones are all the way into the jack. Any ideas?

Often resetting the settings helps.

Sound ONLY in right channel from minijack

Hi
I have a 1.5 GHz 15 inch aluminum powerbook g4, exactly one year old, in perfect working order.
For quite some time now, I've noticed the audio in my bose media mate speakers (1.0) from the left channel has been a bit crackly at times. I thought it was the speaker...I would jiggle the connection and that appeared to do the trick.
The other day, the left channel completely went out. Being the handy man I am, I decided to cut the wire to the left channel speaker and try replacing the connector (as I thought this was the issue). It was, of course, not.
Then, today I went to plug in headphones, and noticed the same thing. NO AUDIO from left channel.
Please note, however, that there appears to be stereo sound coming out of the powerbook's internal speakers.
I have been through sys prefs> sound, and utilities > audio/midi setup, messed around with all the settings....no use. I have the current version 10.4.7 software.
If ANYONE has an thoughts/input/solutions, it is always greatly appreciated.
Thanks,
Bret

Sounds like your minijack is shot, either the jack itself (unlikely) or the jack's connection to the computer.
Unless you very handy and comfortableopening up your computer, you may want to take it in and have it repaired.

Audio output from left channel only

My iPhone 5s (iOS 8.1.1) suddenly developed a problem with audio output last week after about 9 months of ownership. Through the headphone socket and Bluetooth streaming, only the left channel could be heard. I arranged an appointment at the Apple store and they confirmed after they carried out a restore (iOS 8.1.1) that there was only audio from the left channel. The phone was replaced under warranty.
My new phone was partially set-up in store and all I had to do was load my backup when I got home. I loaded the backup from my Mac and tested the audio output. To my surprise, the new phone had exactly the same problem as the one that was diagnosed as faulty in the Apple store i.e., audio output on the left channel only. I contacted Apple support via chat and explained the issue. I was advised to test the new phone without my backup being loaded. I restored the phone and tested the output using both Bluetooth and the headphone socket and there was a stereo output as normal. I reloaded my backup and it returned to left channel audio only. I was advised to then reset the phone and this cleared the problem. Corrupt backup data??
What I can’t understand is that two phones exhibit an identical problem, with one being a hardware issue and the other apparently a software issue. Too much of a coincidence if you ask me.
Is it possible that an app could cause a problem leading to a hardware failure?

Output only in left channel

So I recorded a song and various instruments... everything was going great but I don't know what happened, suddenly sound was only coming from left channel and right channel only gets like reverbs and stuff. At the bottom only one of the bars is showing sound bouncing. How do I pan it back to normal?

It could be that we're both missing something obvious that someone else would see.
However, trashing Preferences (and to a lesser extent Caches) is a way to get rid of GB "ghosts" that mysteriously show up for no reason and mess things up. It often fixes mysterious problems that can't be fixed any other way (short of a complete uninstall and reinstall). When you get rid of preferences, it makes GB appear fresh to the computer. Caches are just temporary files - you can trash all of them and they simply grow back like weeds when you run the program.
If you're concerned about the risk, you could put them into folders, put the folders into the trash, and restart your computer, but don't empty the trash so the prefs and caches stay there "just in case." Open up GB (it will look like it's being opened for the first time), and new preference files and caches will be generated automatically. However, you could always retrieve your old preferences and caches in the trash, and swap them out for the new ones (although it's really better just to trash the old ones).
This won't effect your other projects and may not even help this one. However, it may fix the problem as this sometimes does fix ghost-in-the-machine problems, and is along the lines of housekeeping. It's refreshing some files that occassionally get corrupted, forcing the program to generate pristine new ones.

ITunes only outputting left channel through Soundsticks

I've been using the original Harman Kardon Soundsticks (USB type) for about six years now without problems, but just today they've started behaving oddly in iTunes and Front Row. Only the left channel is now output, through BOTH speakers. They work normally when I use the Quicktime player, but not iTunes/FR. If I switch the output to internal speakers, then iTunes outputs both channels normally. I tried deleting the preferences, and updating iTunes to 8.01 from 8.0 but without any difference. Have also tried rebooting, disconnecting and reconnecting the speakers, and the power to the speakers but nothing seems to make any difference. Additionally, there's no "balance" option in System Preferences for USB speakers.
There clearly isn't anything physically wrong with the speakers themselves so can only assume there must be a corrupted preference file or similar, but have no idea where to start looking. Can anybody help?

I have the exact same problem but I use Windows vista into a MOTU Ultralite Firewire interface outputting to some powered monitor speakers. I know the issue has got to be with iTunes because i can open the mp3 in windows media palyer and it plays just fine in proper stereo. It's really annoying and I cant seem to find the solution.

IMac into cam adaptor into garage band works,but GB only sees left channel.

iMac into cam adaptor into garage band works,but GB only sees left channel. Do you think it's the wiring of iMIcs USB vs. the camera adaptor? Or is there a switch in GarageBand that will bring in both channels? Thanks!

Sorry, I meant iMic into Camera Adaptor, not iMac. (no option to edit and re post ones own post)

Left and right channels of stereo sound coming only from left spea

The title says it all. I can't figure out what's wrong. I checked all the settings I can think of, but nothing seems out of place. It's not the right channel cutting out, but both channels coming from the left speaker (I used the speaker test feature to confirm this). This just happened out of nowhere when I booted up my pc. Any idea what's wrong?
*Oh, and this is an Audigy 2 (plain version).Message Edited by Geise on 2-3-2005 : PM

Did you ever fix this problem? I have the exact same thing happening to my sound.
All the sound comes from the left in stereo sound. I plugged the green stereo analog speakers into the other pin the blackone for 4. setting on my SBLi've24 allthe others play fron t left back left and back right but the front right is so soft like a whisper.
So the speakers work. Im running a Xp mediaedition system. It happened after an apparent sound conflict that made an electronic popping sound which got progressi'vely worse until i figured out how to reset the car d in the Bios level. I have done evrything but reformat the hard dri've All tests say the hardware is working but still no front right channel. Help please

If I have audio coming from left channel. How do I make same audio Left and Right?

Hi there,
I've recorded some footage with a mono mic and it recorded the audio on the left channel of the audio. In FCP. I placed this audio clip as a part of a multi-cam clip but the sound is only coming out the left. Is there a way to set this audio to mono or to make them play the same levels through the left and right channels?
Thanks,
Caleb

Wow! 30 Seconds later, I figured it out. LOL
Under Inspector for audio, you just click on channel configuration, click on channel and use "Dual Mono" mode. Thanks Caleb!

Exports for DVD only include left channel of audio! Help!!!

Hi, I just realized that the files that I have been exporting using compressor have been only exporting the left channel. I am not sure what the problem is and would appreciate any help anyone could give me, as I'm on a big deadline and need to solve this ASAP.
The way I've been doing it, is I right click on the sequence name in Final Cut Pro and select Export > Export Using Compressor. Then I selected the DVD Best Quality 90 Minutes option. The AIFF file that is created seems to only have audio in the left channel. The original files themselves are definitely stereo, and play both channels in Final Cut.
I really don't understand. The Inspector within Compressor shows this information for the AIFF file:
File Extension: aiff
Estimated file size: unknown
Audio Encoder: 16-bit Integer (Big Endian), Stereo (L R), 48.000 kHz
It says Stereo, so I don't know what the problem is! Please help!!!

In the Sequence Settings, I see this:
Downmix: 0
Grouping: Stereo
I also checked the Audio Mixer window and nothing seems to be muted or solo'd. A1 is panned all the way to the left, and A2 all the way to the right, but I'm guessing this is normal, and just the way that stereo channels are shown?
I'm not sure if I have downmix enabled--where do I check that?
On somebody else's suggestion, I tried exporting a non self-contained Quicktime movie from FCP and then dragged that into Compressor and it seems to solve the stereo issue. Not sure why it doesn't work going straight from FCP, but there must be something going on inside there...
Thanks so much for your help. I really appreciate it!

USB Audio Device only plays left channel out both speakers.

usually i use my Yamaha Audiogram 3 usb audio device to record things in cubase, and when the cubase settings are set it is fine, but as soon as i close cubase, the left channel of any audio (like itunes playback) plays out of both left and right speakers in the headphones i use. this only happens when the Audiogram 3 is plugged into 1 certain usb port (of 2).
its even fine when i have cubase running in the background while i play music from itunes. it just doesn't make any sense. it also appears to recognize that its stereo in one port, but not the other.
i would suspect it has something to do with the drivers for the usb device (if there even are any), that the drivers it placed into the system only applies to that one usb port, but if thats the case, you would think it would install new drivers for the other port as soon as i plug in my audiogram, but thats not the case.
no cd for the audiogram. you simply plug it in.
ive tried restarting the computer, plugging it in again, trying to change the settings. nothing seems to work. i need the other port to work.

Try resetting the PRAM. Info here:

You may also want to take a look at the Audio MIDI Setup utility and make sure everything is configured properly there.
