Hi
I'm recording from my analog cassette deck to my mac os x 10.9.5, but get only one channel on audacity and garage band.
deck out - headphone jack -rca to rca mini jack mac sound input
I did read several posts, but to no avail.
I did play with AUDIO MIDI setup
I did play with SOUND ( SYSTEM PREFERENCES )
please help
thanks in advance
peace

Come on... It's just like a usb turntable, only a little better quality. What steps would you use to troubleshoot one of those?

Audio Channels. Only one channel is playing

For some reason only one channel is playing a signal on a couple of clips. The other clips are fine.
All I did to the clips in question was increase the DB levels.
How can I adjust it so that I get signals on both audio channels?
Thanks

Please Help - Audio Exporting-Only one channel

When I export the audio from Final Cut, I get only one channel of audio ( right side). This happens with all the AC3 and PCM audio settings.
All of the settings are correct in Final Cut. I have dual output audio on the meters and playback. I've also done a complete troubleshooting check on my playback system to make sure that everything is working properly. It is. I tunes plays everything back in stereo as does final Cut.
Any suggestions? I'm really behing the 8ball at this point.
Thanks,

Exported Audio Voiceover Only One Channel

I created a quicktime screen recording for a screencast/tutorial using QuickTime X.
Brought that clip into FCPX, added some music, a few transitions and some motion graphics/titling.
Exported to h.264 and I'm getting stereo from the music track, but the voiceover is only on one channel.
So I go to audio settings and batch change everything to Mono. I noticed that there are surround sound settings, that is, multiple audio 'tracks'.
Export and only one channel.
When I monitor in FCP X I heare the audio out of both channels.
When I export it using FCP X H.264 to quicktime: Audio Only On One Channel
Killing me.
So I I loaded the H.264 exported clip into QuickTime Pro 7
Anyway, In QT 7 I changed all the settings for audio (properties) and turned every channel that showed up to mono, saved as and the QuickTime file now plays voiceover audio on both channels. Yeah!! So it seems.
So I save as in QuickTime 7 and when I play in QuickTime 7 I get the Soundtrack/Voice over audio on two channels.
But when I open it in QuickTime X (or upload the file to YouTube/Vimeo) the voiceover only comes through on one channel. Keep in mind that the stock Music does play through both channels!

Why does my nested sequence have only one channel of audio?

Hi,
Working in Prem Pro CC on my Mac Pro.
I have a number of interviews, each shot with 3 cameras and with audio from a separate audio recorder. The audio has two channels, Ch1 has the boom mic and Ch2 a radio mic.
I created a sequence, placed the audio into channels 1 & 2 (they are linked) before placing the video tracks onto timeline tracks 1-3. Everything's synced nicely and so I nested the shots and then I enabled multicam on the nested sequence.
However, now when I edit the nested sequence into my edit sequence, it has only one channel of audio. I tried Modify>Audio Channels but within that page, in the option to select 'Source Channels' the options are "None" and "Channel 1".
How do I get my nested sequence to place both audio channels into my edit sequence?
Any help much appreciated.

Nevermind folks, I figured it out. I had my render control settings set to Apple Pro Res on some timelines.

Why only one channel of sound in sequences? Please someone try this quest

When I add a sequence to a sequence, I have only one channel of sound but, when I open that sequence I have 2 channels of sound.
Is it a sequence setting and if it is I see:
outputs 2
downmix 0
grouping: Stereo selected
Dual mono not selected.
I swith these around a bit but get no change.
My raw footage say "2 Mono" from my Sony DSR PD-150 at 16 bit, 48 khz.
I usuall use one channel for camera sound and 2nd channel for mic.

the number of audio channels that your nested sequence will contain is the same as the number of audio outputs you have selected for that sequence ...
for example, if you create a sequence with 10 tracks of audio, but have only set the sequence to have 2 audio outputs, then when you nest that sequence the nest will have only 2 tracks of audio ... change the audio outputs to 4, or 6, or 8, or 10 etc regardless of how many tracks you actually use, and the sequence, when nested, will have the same number of audio tracks as the sequence has audio outputs
... ok, so that explains the relationship between audio outputs and the number of tracks of audio that a nested sequence contains
so why are you getting only one channel of sound when you edit it in to another sequence? my guess is that you are only patching 1 channel ... load the source sequence into the viewer (drag and drop), now check in the patch bay area at the left of the timeline window to make sure that your a1 to A1 and a2 to A2 connections are not broken ... and edit it in.
cheers

I'm deaf in one ear and need a stereo-to-mono earbud so I can use my iPod and iPhone. It is not good being able to hear only one channel. Can Apple consider making such a thing for those of use who need such a thing?

I'm not sure which version iPod you have, but I just checked my iPod nano (current generation) and it also has a Mono Audio setting in Settings>General>Accessibility.

???_Missing audio on one channel in Prem.Elem. 4 & 7_???

Hello everyone,
I have a problem concerning Premiere Elements 7 and I can't find a solution to it. Maybe one of you had this before and is able to help me out.
I have a project with several clips where I removed the original audio and added a soundtrack file to play along. The problem is that there is only audio on one channel when I play the scene in preview. Balance is set correctly, audio file is all right. If I look at the audio file in the audio preview window both channels are visible and play just fine. If I look at the audio mixer and start the scene preview both channels are visible in the peak meter but I still only hear one channel. It doesn't matter if the audio is mp3 or wave. I looked at the audio preferences (audio output mapping): when I change the speaker setup, change right/left channel for the output devices the missing channel changes to the other side. It seems it is somehow connected to these settings. But it's the same settings as with other projects which work fine. So it's gotta be a project-related problem. It's not only in the preview missing but also when I export the scene to file. It is only with this project, but it's too much work to rebuild it. I tried the project with Premiere Elements 4, but it's the same. Other projects work fine.
I'm running it on Win XP+SP3, Intel 2,8 GHz, 2 GB RAM, Nvidia 6800 GT, MSI 865 PE with onboard C-Media 9739A sound chip, lots of HD space.
Any suggestions on how to solve this problem would be very much appreciated.
Thank you,
Chris.

Thank you both for your answers. The audio file is stereo with different waveforms for each channel; I just checked that in Adobe
Audition. I also checked the settings of the audio card but there's not much I can change. After these problems occured I updated the
audio card driver to the newest version available. The audio files comes from the video clip I use in the sequence originally. I severed it from the video to edit it in Audition and re-imported it since Premiere Elements hasn't that much sound editing tools. The audio file is fine. There's no channel volume effect applied to the file. As I said I can load it into another project and everything works fine. Gotta be something in this project.
Ok, ok I found it! I was playing with the audio tracks and I moved the audio file to the soundtrack track and it works! Putting it back in Audio tracks 1 or 2, one channel is missing. Very strange behavior. Or is there a way to mute one channel on a whole track since it happend to all audio files in Audio tracks 1 or 2?
Anyway, it's gone and that's great. Thank you for your help!
Chris.

Only one channel working - fixable?

Recently my ipod starting playing only one channel through headphones or a speaker jack - eg I can hear only whatever is coming through the left side speaker. I've verified that the problem is with the ipod, not the headphones. However, if I put pressure from a specific angle on the headphone cord right above where it connects to the ipod, both L and R channels work. This goes away again when the pressure is released.
Has this happened to anybody else? Is it a fixable problem?
Thanks!

You need to replace the headphone jack on the iPod.

Only one channel plays

I am only getting sound out of one channel of the ipod. I have tested this via the ear buds, but also by routing the sound to my stereo -- only one channel has any sound on it. Is there some setting or something simple that can be done to fix this?

i dont beieve there is anything you can do. but im not an expert, so take it into an apple store and ask someone for help.
(some key information here would be what model it is so others know about it).

Can get sound from only one channel

I am having trouble with my sound. I am able to get sound fron only one channel. Is this something I

Did you check System Preferences>Sound to make certain that the balance scroll section was in the middle?

Ipod classic sound from only one channel

My 80GB Ipod classic has sound from only one headphone. Same problem when docked so it's not a headphone or socket problem. It's as if only one channel is working. Any ideas?

ONLY ONE CHANNEL OF AUDIO WITH SONY PMW-200

Hi,
When I automate to sequence using video shot on my Sony PMW-200 I only get one channel of audio, when the preset in Premiere clearly states 8 channels of 24 bit audio. If I drag a clip to the timeline all 8 channels are there, but then I have to trim the beginning and end of each clip in order to do transitions, which would take forever on a wedding video. There must be other PMW-200 users who have this same problem. I am shooting in UDF mode 422 at 50 mb/sec on the Sony and just updated my Premiere CS 6.
Thanks,
Ed

similar question, I found a thread that may solve your problem: Sony PMW-200 file import into Premiere Pro CS6 only get 1 Ch. audio, you can go for a look. Or you can try some converters to help you. Handbrake, any video converter, ffmpeg,imixmxf, transcode them first, then reload into premiere.

MSI-Gm2-only one channel audio output

Hi everybody ,
Its nice that guys are working hard to solve every one's problem. Keep it up !
Recently I upgraded the bios version to 1.4 (the latest) also the Realtek HD audio drivers but not system chipset drivers (which is 170mb too big).
Now I am able to hear only right channel of my onboard audio (ALC 888, 8.1 channel i guess) as I am using 2.1 channel. what could be the problem. Is it hardware problem or bios problem. My system configuration is as follows:
CPU: Amd 3800+ X2
MOBO: MSI-GM2 (690v chipset)
MEM: Kingston 1GB 667Mhz
VIDEO: onboard (ATI X1200)
HDD: Sata 80GB Samsung
If you guys can help me figure out what it is? Thnx in advance !

Hi!
Chack audio settings in the Realtek console and in Windows Settings -> sound.
Why did you update bios? Was there some compatibility problem with your system that required the flash? If not, then keep in mind that updating bios when it's not needed can cause many problems. So, if nothing helps, you may want to flash back to the old version you had. Same goes for the drivers.
Now, please note: only flash back if nothing else solves this problem! I don't think that flashing the bios lead to this audio problem, so leave the bios alone for now. Try downgrading drivers. Newer drivers aren't always better ones!
Hi Hans! first of all thanks a lot for your kind reply. I updated my BIOS for no such reason. I thought it is always healthy to update BIOS to avoid future compatibilities problem (silly move of me I guess) and be future problem proof. I checked all the possibilities in Realtek concole but no improvement. I now noticed that when I switch off my PC the channel which is dead produces weird sound like shrill noise as the power of speaker is on. As now I switch off the UPS after PC shutdown the noise from the speaker goes off with the noise like Siren fading from High to low.
What do you think this is ? Oh sorry please do not get mad at me as I forgot to mention that I used Audio Splitter at the Line-Out (2.1 channel) to drive independent Audio Systems e.g. 1) low wattage lower end music system. 2) High end Audio system with High wattage. They both were driven simultaneously.
Do you thank I screwed it up ? In any case I shall follow what you suggested i.e. Flash Back to older version. Problem is I do not have Floppy Drive and I do not know how to do it with MSI live update. Your insight solicited and awaiting your expertise. Thnx a lot buddy. You care !

Detached audio records one channel only

Video clip in event library plays two channels audio
Normal
But dragged into project as a VoiceOver it only plays on the left channel
Big drop in audio level
Desperately seeking solution

Hi
No not in iMovie 6.0.3 - but
You can export out as QuickTime expert mode - here select audio only and as .aiff
This file You can edit in any audio editor eg Audacity (free on internet) and then
save and re-import into iMovie.
or
As I remember it You can even out in GarageBand - but I've never done that.
To me the Export to Audacity (or other audio editor) and re-import is easiest.
