Arcam rDac plays only left channel. OSX is 10.7.4 and iTunes 10.6.1. Have somebody similar problem ?

I have usb audio dac Arcam rDac and Mac mini 2011. Everythings was working without problem, but propably after upgrade OSX on 10.7.4 and iTunes 10.6.1 Arcam plays only left channel. Have somebody similar problem and sollution ? Thank you very much for your help.

Did you solve your problem?
I have the same rDAC and Macbook pro. And I have sound in both channels, but I have popping and crackling distorted sounds at low frequencies, in left channel. Very very annoying. I have looked at every forum, and it seems like Mac has this problem very often, and there is no viable solution so far.
Like many others, I too am very disappointed with this very expensive computer I bought only 4 months ago.

Imported DV plays only left channel audio

In working with iMovie HD 6, I've imported video from my DV camera and I'm only getting sound from the left channel (I used a lapel mic plugged into the camera while I was recording). Is there a way to mix the left channel audio into stereo, or at least two channel mono so that my movie and subsequent DVD project will play sound in both channels? I'd prefer to run the fix within iMovie, but will consider exporting if necessary. I can't recreate the original interview without a lot of work.

Welcome to iMovie Discussions.
Yep, you can do it in GarageBand, just setting it to move the mono channel into both channels.
Or you could use the free, downloadable "Audacity", and just select the left channel, then copy it, and paste it into the empty right channel, like this.
However, to use the wonderful "Audacity", you've got to find your original audio in iMovie, then remove it from within its hidden storage, whereas GarageBand just "knows" where to find the audio if you send your movie there, so click on Share and then GarageBand, where you can select the Movie Sound track, and just turn the little 'panning' control, in the Mixer column, to the centre.

Stereo audio plays back left channel only - premiere pro CC2014

Dear All,
I recently upgraded to premiere pro CC and find that (just like sometimes in CS6) when i place an audio track (or clip with audio) to the timeline it plays back LEFT channel only. When I move the same clip to another (existing or newly created) sequence it becomes two channel stereo and plays back OK.
The question is, since i created sequences with the very same audio settings, what might cause this issue.
(fill right with left channel does not work because it IS a stereo track i suspect sg is wrong with my sequence settings- but i cannot figure out what exactly.)
I hope it's not a bug and it is just me doing sg wrong. all input is highly appreciated! THX in advance!
Misi

I know i just happened to be mid-project when trial period ended...
Still looking for the why's though, since I asked around and there ARE some people who expőerience similar issues!
Thanks in advance (Ann, too)

My MacBook Air headphone jack only left channel works

Builtin speakers are working fine on my MBA 2012, but when I plug any kind of headphone into the jack, only left channel works. If I tune output balance to right, then sound nothing.
I found there are only four metal contacts in the jack, two on each side, then one for ground, the other one for left channel, none for right channel, what about yours?

At last, found it isn't a problem, actually any 3.5mm headphone of standard can work, just plug into the jack fully ( only one mm left ) . enjoy ~~

Have you checked the Software update page at the App Store?
And do you have iLife '11 and iWorks '09 installed? Only these versions are eligible to be updated to the new versions.

HT1222 I got disconnected after the release of the last update! I'm disconnected only from the app store and itunes. Do i have to update to activate my account? What to do, i'm stuck.

Have you restarted your phone?
If so, try a reset. Press and hold the home & sleep/wake buttons until the screen goes blank, ignoring the power off slider if it comes up.
Check for the app again after the phone starts back up.

Hi Patrick,
Yes, a very frusterating issue indeed. Someone else had mentioned a possible issue with real player, I tried getting rid of that and same issues. I even got completely rid of firefox for the moment. Guess what, problem still is persisting. I think this means it maybe something else altogether. I will go back to re-add firefox after I get this straightened out but now using Chrome for the moment.
What I've also found out is that the sound can be restarted when I unplug and replug in the 3.5mm speaker cable from the audio output jack on the back of the computer. Any ideas?
Thanks!

Hello!!! i've just updated osx to 10.8.5 and itunes to 11.1.1 when i open itunes it crashes continuously!!! pls help!!!

Asking me what I think is not what really matters here. What do you think? Do you want to wait for another update to iTunes in order to sync or backup your iPad again? That could be weeks down the road - no telling when it may be updated.
Why dont you go through this support article and see if any of this stuff helps you? The article is for Windows users.

Here is something very simple to try. Quit iTunes and restart your computer. Then restart your iPad and try to sync/connect again.
Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.

Zoom H4n Stereo Audio Plays Only Left Speaker - How to Double It?

Hello Everyone,
I've been working on a few projects and noticed that the audio captured by the Zoom H4n will preview in both speakers (and before I drag it to the timeline I can right click -> Modify ->Audio Channels and get all the options there as well as hear it from both speakers) but as soon as I drag it onto the timeline it will only play through the left speaker.
Any ideas of either where I'm going wrong or how I can double the audio? It's all already cut together so I'm hoping there's a fix that is semi-time efficient to apply lol. Thanks so much for your help,
-Karl

Glad that helped! Next time, you can use the Modify > Audio Channels command to handle this before editing. If you only have audio on the left channel of your stereo source clip, or don't care about what's on the right, you could set the stereo audio to be treated as dual mono. When you put the mono source tracks into a sequence with a stereo master track, the mono source will automatically be routed to both stereo output channels. You can then use the Pan knobs in the Audio Mixer to position each sequence track in the stereo spread. This has to be done before you use the source clip in a sequence, however.

Logic Express Presonus Firebox only left channel output in phones

I upgraded from GarageBand. I have a 17" MacBookPro and a Personus Firebox. I configured the AudioMidi Preferences on the Mac to the Firebox for input and output. When I play back a mono track I only hear the left channel in the phones. I am panned to center. In GarageBand when I configure the Mac as the Audio Driver I hear my mono mix in both L and R phones which is what I want.
Also, in Logic Express, I get no sound when I configure the audio out to the Mac. It needs to be routed to the Firebox.
Any ideas?
Thanks, Jonathan

Thanks for the advice. I tried listening to a song from my itunes library, not using Logic and I still heard just one channel. The culprit must be a faulty connection in the Firebox.

Capturing only left channel of audio

Probably not a great combination using Premiere Pro cs3 for about the 3rd or 4th time (after years of 6.5) and using the church's sony camera that I am unfamiliar with - but here goes:
When I play the video back on the camera, the sound is in stereo, however when I capture it, it only plays back and captures the left channel. I didn't have this issue with my own camera, so it may be a camera issue. I can't figure out/find the model of the camera, but it is a Sony HDV running in DV mode. The sound was recorded in 48K stereo. Any thoughts/help is appreciated.
Bob

OK.
Start a new Premiere project and use that to test capture again.

Only left channel records - help please

Here's my set up. I have DVR with a bunch of movies. I am taking S video out and RCA audio out to a Sony DCR TRV 120 camcorder. This camera can act as a DV bridge. I am going out from the Sony via FW into my PB and trying to capture the movie in iMovie 5.0.2.
Everything is working except that I am only getting audio from the left speaker on the computer. I checked the computer in iTunes and sound comes from both speakers. I checked the camera with headphones and there is sound coming into the camera in stereo.
So, it must either be that I am losing the right channel via FW or the DV bridge in the camera.
I have imported many movies from Hi8 tape without a problem. Is there anything I am missing here? Should try to go from the camera's headphone out to the audio in on the PB? Could it be a faulty FW cable?
Is this a problem with iMoive 5.x? I have read this forum all night long and not found anyone else with the problem.
I appreciate all replies.

"..I checked the computer in iTunes and sound comes from both speakers.."
So the computer's audio is OK.
"..I checked the camera with headphones and there is sound coming into the camera in stereo.."
No: probably not real stereo; it may be the same mono audio coming out of both channels (left & right), giving you the same mono audio in both sides of the headphones. The camcorder may be trying to 'do you a favour' ..and, because it's receiving only mono, it's helpfully(?) playing the one incoming channel out of both headset channels.
"..So, it must either be that I am losing the right channel via FW or the DV bridge in the camera.."
No: FireWire is just a digital link which carries exactly what it's being fed - you can't lose a right channel via FireWire: it passes on exactly what it receives ..like handing on a cake to someone: the person who receives it from you wouldn't receive it with half the raisins or the self-raising flour or the egg missing ..it's all handed on complete.
"..the DV bridge in the camera.." Well, as I said; I think you'll find that the camera is receiving only through its left channel, but is providing that left-channel audio out of both sides (..left & right..) of your 'phones.
So the problem is probably at the very source: your "..DVR with a bunch of movies". Either the movies are recorded in mono, and that's leaving your DVR through only the left channel, or - even if the movies really are stereo - only the left-channel is active (..is connected properly, or has sound going through it..) from your DVR to the Sony camcorder.
One way to fix this is to take the output from the left-channel of the DVR, and feed that to both the L & R cables which go to your camcorder. Use a 'splitter/joiner' like this..
..so you'd connect the left audio channel out of the DVR (..should be a white RCA/phono plug..) to the single pin of this adaptor, and then connect the pair of RCA/phono sockets on the back of the adaptor to both the left and the right audio inputs of the camcorder ..you may be using a 3.5mm jack plug to connect the phono plugs into the camcorder's input.
This kind of little mono to both channels adaptor is available by mail order from most electronics stores, e.g: here, and the simplest place to find one in the States is probably Radio Shack, or that kind of store.
It's a common problem..

Exports only left channel

When I replay the video within PrE 10, the sound is stereo. However, when I export it (tried several format, ie WMF HD ) it will only play sound in one of the channels.
Doees anybody know, what could be the problem here?
Best regards,
Peter

I've just been experimenting with this for a couple of hours. It seems to be something in the settings for the project. I've tried to import exactly the same media (footage) to a new .prel file, I made from scratch and here sound works perfect. I've also tried to delete all the clips in the timeline for the problematic .prel file, imported new media and placed them in the timeline. This again gives only sound through the left channel after exporting.
The thing is that I've made a bunch of .prel files for a project where we need to make a lot of short videos. They are all based on the same template file (I made one .prel file that contained all the footage I needed, so I didn't have to go through the import process for each video, I made). Therefore starting all over again will really be a pain. I guess that it is a setting or something which I've made wrong in the "template" file and which has thus been replicated to all the other files. The strange thing is that the balance is perfect when reviewing the video inside PrE, only after exporting it, no sounds comes in the right channel.
I simply can't understand what I do differently in the new files and what I did in the old template (and thus in all the other files I've made). They have the same project setting, as far as I can see.
Bill, I haven't been able to find out if it has keyframes. It sounds quite possible that this is what I've done without knowing it, but on the other hand, it's strange that it changes this many times during a couple of minutes. And after investigating I found that not all the videos have this behaviour, but all of them gives only the sound through the left channel after exporting. So probably the two problems are not interrelated.
I really appreciate your help. Thanks a lot.

Keynote Audio only left channel

Has anyone else had this problem and how did you solve it? I am using an M Audio Fastback USB input to record to Keynote and the audio is only recording to the left channel/speaker. Can someone tell me what I am doing wrong or how to fix this?
Thanks,
Paul

System Properties > Sound
in the output tab, select Fast Track USBand centre the Balance slider
in the input tab, select Fast Track USB and move the volume slider to the far right
Applications > Utilities > Audio MIDI setup > M-Audio > Input; set the master to the far right
The front panel controls affect analogue phono out connectors and the headphone jacks for monitoring, they do not control recording.
