T510 stereo audio connection options?

OK, this may have been asked/answered already, but I am wanting to connect my T510 laptop to my stereo amp preamp out RCA jacks so I can rip my vinyl collection to my computer. The issue is how....the usual way to do this would be to use a 'line in' computer input, which the T510 does not have. I am led to believe that the combi headphone/mic jack will not allow routing a stereo signal to the sound card, IF I AM IN ERROR ABOUT THIS, please advise, as that would solve my problem (twin RCA to 3.5 mini-plug would then work). The other potential options would be using USB, or perhaps the 4 connector firewire port, but I have absolutely no idea whether that would work. If anyone has experience in doing what I need, please help.

It sounds like you have a "ground loop" hum. This results when the ground plug for two different components in an audio system (your iMac and your stereo, in this case) are probably plugged into two different electrical outlet receptacles in the wall. A slight voltage difference potential develops on the ground (third lug on the electrical plug) between the ground on the two devices resulting in a 60 Hz hum. The available soutions consist of "lifting" the ground on either the iMac or the stero by using a two-prong cheater plug adapter, available at an electronics or hardware store, that either the iMac or the stereo is plugged into and then this plug plugged into the wall. This breaks the "ground loop" and the hum.
The two-prong cheater plug costs about $1.00 US.
An additional thought: also, more importantly , if you have a "Cable"TV connection to your stereo/TV setup and/or to your computer with the internet signal, THIS is usually another serious ground'loop culprit relative to the ground on your system. The ground level on the Cable TV network is diiferent than the ground level on the electrical grid in the US. This really results in 60 Hz hum. The only solution, if this is your case, is to buy a "ground loop Isolation Transformer" (I have to use one on each of my two stereo system - cable TV/computer systems. This ground loop isolation transformer is priced at about $ $90 US, but will really solve this problem. The incoming TV/internet Cable is screwed into the little isolation transformer and then that is attached with a length of cable to the stereo or computer.
I know this all sounds complicated, but it is an actual probelm we audio/video-philes face with our complicated electronics and have to fix.
Hope this helps

No "connect to audio device" option for E71

I've been trying to connect my nokia BH-102 headset to my E71, but when I go to the Paired Devices tab and press the option button, the "connect to audio device" option is not there. The only three options that appear are "new paired device", "help", and "exit." I've searched for soltions for this online, but thus have not come across any mention of this problem. Am I missing a firmware update of some kind or is this an entirely unique problem?

Solved my question. Somehow 20 minutes of searching the forums didn't turn up the solution but when I posted my question the box on the right had 3 posts with a similar question and solution. Sorry this has become a repeat post.
I would delete it but can't.
Here is a link to the solution that worked for me. I used ONYX.

No HDMI audio out option, only Airplay

Hi everyone,
Hoping to get some enlightenment here as I am at my wits end. Here's my setup:
Macbook Pro (mid 2011 era)
Belkin MDP to HDMI converter
Monoprice HDMI cable to Denon AV-1912 receiver
Prior to upgrading to Mavericks and numerous updates to my Apple TV, I was able to plug in to my Denon receiver via HDMI and get display and sound options pop up through System Preferences, no problem. Everything worked beautifully. So there is no issue with my sound card not supporting HDMI.
Now, whenever I try to connect through HDMI, I can only get the display to work. Trying to bypass the internal speakers through the Sound panel in System Preferences yields no results. My Denon receiver only shows up in the Sound Output panel as an Airplay option, not as HDMI. When I select it as Airplay, the receiver automatically switches to the Airplay (Internet Radio) source and kills the display connection it had made with HDMI.
I can't for the life of me figure out how to either:
a) Disable Airplay in my Denon receiver OR more apropos to this forum,
b) Get HDMI restored as an option in my Sound Output preferences.
Any suggestions welcomed!
Thanks,
Jeff

I have the same issue. Setup is:
-- mid-2012 MBP (non-retina) running 10.8.5 (including the very latest supplemental 10.8.5 which was supposed to fix a different issue with an HDMI audio connection not working after a Mac's wakeup from sleep).
-- MBP connected to a Harman Kardon BDS 577 AV receiver's HDMI input (this is a 5.1 receiver, connected to 5.1 speakers).
-- MBP and receiver connected via PNY mini-DP-to-HDMI adapter, which both its Amazon description & review explicitly say supports passthrough audio on Macs, and a high quality AmazonBasics HDMI cable (ditto).
-- The receiver's HDMI output is connected to an Epson EH-TW3200 projector's HDMI input (projector is Euro version of the US Epson 8345; it has no audio whatsoever).
-- The Epson is set to mirror the MBP display, and the MBP's internal display resolution is set to match the Epson's (1080p), which appears as "Epson PJ" in the menubar's Displays pulldown.
1) The issue we're having here is very clearly different from the one with the HDMI connection not working after wakeup (numerous thread about it in Apple Discussions & other forums), since there the HDMI option for sound output device is available (in the Sound Preferences panel, the equiv. menu-bar shortcut and in Audio MIDI Setup and VLC Audio --> Audio Device submenu), but didn't work properly after wakeup.
2) With our issue, when everything is connected but the projector is turned off, sound works fine. I have the option to select HDMI in all the aforementioned locations (the device is called "HDMI TV"), and, when chosen, sound is properly output via the AV receiver according to the source material (5.1 with both DTS and AC3 encodings work fine, as does stereo).
3) As soon as the projector is turned on, video appears fine as expected on the projector, mirroring the MBP's screen, but the HDMI option disappears from all above lists of sound output devices. If I was in the middle of a movie on VLC, audio switches to the builtin speakers on the MBP.
4) Trying to trick the sytem by defining a new audio aggregate device in Audio MIDI Setup when the projector is off, having it include the HDMI device, and then trying to choose it when the projector is on doesn't work -- the aggregate device is grayed out and can't be chosen.
5) TjoffenF's solution above doesn't help me: For me VLC behaves exactly like the rest of the system, so using it doesn't help. I tried several versions of VLC, including old (1.1.2) & new (2.0.9, 2.1.4).
6) Jackmo69's solution doesn't work for me either: The order the various components are switched on and/or connected doesn't matter. As soon as the projector is on, HDMI audio option simply disappears and the MBP stops using the HDMI port for audio.
7) Generally, this seems to be a problem with something called EDID. This is the protocol which HDMI and DVI devices use to tell each other about their capabilities (resolution, audio supported, etc.). Somehow the Mac thinks the HDMI device it is attached to has no audio at all, so it falls back to its internal speakers. I initially thought the problem was with my AV receiver -- whether or not the projector is turned on, it should report its own EDID, not the projector's, so I shouldn't have seen the "Epson PJ" option, right?
8) I contacted the local tech support for Harman Kardon. They hadn't heard of an issue with their receiver, but don't have Macs. From their POV, which sounded reasonable, if the issue occured with a PC laptop, they'd agree that their equipment was the culprit. They lent me a a Windows7 laptop with a builtin HDMI port (Dell Studio 1558) for a week to test.
I performed hours of experiments with it, replacing the MBP with the Dell, all other things in the setup being identical with the exception of the PNY adapter (same AV receiver, same projector, same cables, same VLC version, same source files).
9) The result:
With the Dell, all the source files output audio via HDMI to the receiver with no issues, and turning the projector on or off has no effect on the audio. To me, this proves that the issue is the Mac, probably an HDMI driver issue. AFAIK the PNY & similar adapter are simple mechanical adapters (the actual video signals are identical), so given it transmits audio fine from the MBP (when the projector is off) I don't see how the adapter could be the problem (I don't own a TV, so couldn't test with one).
10) Extensive googling yielded a couple other people with similar problems using various Macs (earlier but still post-2009 MBs and MBPs as well as a Mac mini), projectors and AV receivers. Their solutions were to (a) run TOSLINK audio seperately from the Mac to the receiver (not an option for me, since my receiver accepts TOSLINK only for an audio-only source) or (b) use an EDID emulator device, which spoofs the EDID so the Mac will agree. There was at least one person who had the issue appear after upgrading fromOS X 10.6 to 10.8 (Mac and other components didn't change), which is yet another indication this is a Mac driver issue.
10) I really don't like the idea of EDID emulators; it's a kludgy solution (needs its own power supply and additional HDMI cable), expensive ($100-$150), and not available locally. Reports on them say they don't always work.
11) I'm very much ****** at Apple at this point. The only solution I can see right now is to buy a media streamer with HDMI output, to circumvent the problem -- not an ideal solution, since it means adding a middleman, but cheaper and and more likely to work then an EDID emulator. (Incidentally, an Apple TV wouldn''t work for me as a streamer because it supports very few video codecs & file types -- not that I'd be happy to give Apple more money to fix a problem they're reponsible for.)
If anyone has since found another solution, I'd realy appreciate hearing about it.

Stereo Audio Linking issue

I have recently moved to FCP from FCE...I am having a problem linking a stereo audio file, I want to edit audio without effecting video in timeline. When I unlink, the audio file acts as two mono files, so I have two do repeat edits. If I link, then the video is in the edit. I want unlink audio/video, but treat stereo audio file as one edit...does this make sense to anyone?
This was easy in FCE, by default it acted the way I want. I'm sure I have a setting incorrect...IDEAS?

You don't have to Unlimk your dual mono clips.
If you want to cut or ripple or slide or whatever, just hold the Option Key and then drag the head or tail of the video part of the clip. It will then only move the videopart...
Or press that button on the top-right corner of the timeline (or Shift L). It toggles the usage of linking on and off (by default there are 2 buttons there. The other one is 'snapping' ('n' on your keyboard))

Stereo Audio Treated Separately, How Do I Link?

I recently migrated from FCE to FCP. I love FCP, but there's one difference that's bugging me. In FCE, when you selected and manipulated a stereo audio track, each channel was linked, so when you changed the db level or applied a pen point to one track, the same would be done to the other. In FCP each audio channel is treated separately, so I'd have to repeat the same process for both channels. Is there an option or hotkey to make each audio channel linked like in FCE?

You can also use command/apple L to link/unlink the stereo pairs or individual audio tracks to video.

Stereo audio export showing as mono

Hi,
I've been encountering an issue with exporting stereo audio from Premiere CS6 (v. 6.0.5) and After Effects CS6 (11.0.2.11). When I export a clip with stereo audio from Premiere or After Effects (usually to ProRes or Uncompressed QuickTime), the resulting file will show as having dual-mono audio in FCP7. When I check the file in QuickTime 7, QuickTime 10, MediaInfo, Premiere, After Effects etc., the audio is tagged as stereo. But when I bring the clip into FCP7, the audio shows as two separate mono tracks.
While this isn't a problem if I stay within Premiere/After Effects, it does become an issue when I need to work with the clips in FCP7 (they have to be relinked as audio pairs in the timeline), and one of the external distributors I work with has come back saying the file we delivered did not have the audio properly linked as stereo.
Am I doing something wrong here? I don't want to have to workaround by putting everything through FCP7, as we are really trying to keep our workflow within the Adobe suite and retire FCP!

Hm, not from what I've seen. Anything that's been exported as stereo through FCP, Compressor, MPEG Streamclip, Episode etc. shows up as properly linked stereo in Final Cut.
I just ran one of my Premiere exported files through MPEG Streamclip to the same format (ProRes, uncompressed stereo audio) and it showed up as having a linked stereo pair in FCP7, while the original showed 2 mono tracks. I am definitely exporting from Premiere with the stereo option selected (and stereo source audio).

Stereo audio goes to A1 and A17-destination track problem??

So I'm working with stereo audio that I've recorded via the Voice Over tool that was originally in my timeline. I recorded a ton of different clips of voice over so in the end, I put them all into the Browser, renamed them, and changed nothing else (I deleted them from the timeline).
This doesn't happen with any other audio than my voice overs, but when I import the stereo audio into the timeline, it goes into A1 and A17 (I had 16 tracks of audio, none of them empty, so it created a new one just for the second track of my stereo audio). Or if I put the first of the stereo tracks into A2, the second one goes into A16, same for A3 it goes into A15, A4 and A14, etc.
I've looked through all the user preferences and there's nothing that will change it. I've tried unlinking them and that doesn't work (I assume because it's stereo audio).
Someone please help!
Thank you in advance,
ACC

You need to connect the Source "patch panel" buttons to the correct Destination Track.
In the illustration below the source audio 1 & 2 goes to destination 1 & 2:

Stereo Audio tracks unlinking themselves ...

Hi All,
I'm still using FCP HD 4.5.
My stereo audio tracks are automatically unlinking from each other and becoming separate mono tracks. I'm not unlinking them, they just suddenly started doing this on their own. I'm having to go back, highlight the two mono tracks, and click option-L to get them back to a stereo pair.
In some of these cases i have unlinked the audio track from it's video track (APPLE-L), but not in all cases. Either way, i can't figure why this would make a stereo audio track unlink itself into two mono tracks.
Ideas? (Besides upgrading my version of FCP)
Paul

You do not say if this in your timeline. You probably have the link button depressed or undepressed.
Check that first.

Stereo Audio recording in Captivate 6?

Hi, I am having problems with capturing stereo audio in sync with the video, in Captivate 6. I am making training videos for music software and have looped back the audio from the programme into Captivate, in order to record it's output. It monitors fine, but it looks as though Captivate is only recording the audio in mono - and there are no settings to change this. Is this the case? I really need stereo sound on the input, otherwise functions in the programme cannot be demonstrated correctly. I have looked through the forums and it would seem that stereo recording was definitely included in earlier versions (as it caused some users the opposite problem of sound from a microphone only appearing on one side). I am using Captivate version 6 on Windows 7. Please can you help me? Cheers, Mike

Hi Michael,
There is no option to select the audio recording as stereo or mono at time of recording.
Can you tell me that have you installed captivate as a part of suite or it is a stand alone Product?
If you have installed Captivate as a part of E-learning suite there is a software called as Adobe Auditon which also gets installed as a part of suite , which can serve your Purpose , It can record as stereo as well as mono. and you can directly insert the audio generated from this software in Captivate.
And In Captivate also there is an option in Edit > Prefrences>Publish settings.
You can uncheck the Publish as Mono option while Publishing and check if it works for you.
Please check the screenshot
Thanks and Regards

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.

Does Apple TV and Optical Audio Connection work?

I've read several posts regarding this issue and I'm a little confused. Does the Optical Audio work on the Apple TV (generation 3), because I haven't been able get it to work. I get sound but no stereo/surround sound. Yet, using the same connection out of my Receiver for my PS3 I do get stero/surround sound. Have I missed a setting on the Apple TV?

Is there away I can check the Apple TV Optical Audio connection to see if it's working? The physical connection seems to be fine. Since the connection to A/V Reciever works, as confirmed by my PS3, I can only assume the Apple TV Optical Audio connection is faulty. Other ideas on how I might validate if the Apple TV Optical Audio connection is truly "broken."

Best audio connection

Best audio connection ?
a) itunes computer via RCA stereo connection to home theatre
b Itunes computer streamed to Apple TV , Apple TV connected via optical cable to home theater
c) this I have not tried ... Itune computer connected directly via HDMi to home theater
Also does the sound-card in the computer make a difference ?

I have Fredereih ataxia so my only hobby left is musique and no way I have the dexterity to insert a cd in a tray, I have 400 cd's all ripped at 196kb.
I love my Ipad with Itunes and the remote app to take control of my 5 computers in the house.
My apple tv is ok but I do not have a good internet connection.
In the room where I listen the most music, I have a small EEE laptop.
it is directly connected on a 925 pioneer receiver with 9 speakers (RCA)
Also in this room I have the apple TV connected via the Digital audio cable
Recently (I'm in Canada ) I have been using RDIO (Like Pandora) , they claim sending in 256 kb.
I now notice that here is a difference in Quality for the same file sent it different ways.
played directly from the Pc is not as good as if I use Airplay ?
a) should I resample my 400 cd's at 320kb ?
b) should I buy another Laptop with a good soundcard and a HDMI output.
I would appreciate any recommandation for any laptop under 1000$ ( Only Itune will be o n it.

"Play stereo Audio as Mono"

I recently was tearing out my hair because I had mono checked (somehow). It was playing Mono through my Apogee Duet Audio interface, but playing stereo through my headphones jack on the core audio. I remembered it always worked fine in Snow Leopard, so I installed SL on a partition for testing purposes and sure enough the Duet played in stereo. So naturally I thought there was a problem with the drivers between Lion and the Duet. After much discussion with Apogee, frustration and online searching I found out about this "Play stereo Audio as Mono" business.
In your next update or release, please link "Play stereo Audio as Mono" in the Sound preferences pane as well. It is a major problem when your audio is playing in mono and you cannot figure out why because the option is hidden away in "Universal Access". As a non-impared user of OSX I have no need to go into "Universal Access".
Thank you.

You could go around the issue by running a script at login to set this option. Here's a script I found on the net:

                    reveal anchor "Hearing" of pane id "com.apple.preference.universalaccess"

click checkbox 2 of tab group 1 of window 1
          end tell
          quit application "System Preferences"
end run
--script ends
(It requires the "Enable access for assistive devices" pref to be enabled.)
Save it as an app in a convenient location (eg, <~/Library/Scripts>), and add it to your Login Items. It will run every time you log back in. Note that this is a toggle—if the preference is on, it will turn it off.

"Up Mix" from 2-channel "Stereo" audio content to 5.1/7.1 Surround

Hello,
This is a feature that I had strongly hoped would make it to Media Center in Windows 8, but didn't. Please consider this for a future update and/or the next version of Windows...
Feature Request: "Ability to Configure Stereo Up-Mix Capability in Windows Media Center and/or Windows Media Player from 2-channel Stereo to 5.1/7.1 Surround so Stereo MP3/WMA audio files output to *all* speakers in my system, not just the left and
right main speakers."
More information:
My audio content (MP3s, WMAs, etc.) are of course all 2-channel stereo format (left channel, right channel). My home theater PC outputs to my home theater receiver (which is a 2012-model Sony 5.1/7.1 receiver) via HDMI. When I play
2-channel music (MP3s, WMAs, etc.) from Windows Media Player (WMP) and Windows Media Center (WMC) both in Windows 7 and Windows 8, I only hear music from the left and right main speakers, *not* the subwoofer not the rear surround speakers.
In order for this to happen, WMP/WMC would need to "up mix" the stereo signal to take full advantage of my physical speaker configuration (as specified in my Windows' Playback Devices configuration, which Windows is able to discern from the capabilities of
my receiver). Media Center even has an Audio setup in which the end user configures the audio configuration to either Stereo, 5.1, or 7.1 yet music is still output over only two channels!
I would like to see WMC/WMP either "automagically" perform the "up mix" or provide the user with an option to enable/disable it when 2-channel Stereo audio content is played.
Too difficult? Rhapsody.com already accomplishes this with its online audio player! Note that my audio equipment has the capability of forcing output to two channels between the PC and the receiver, which my receiver will then up-mix, but this
requires physically maintaining a dip switch and also several button presses on my receiver's remote... and this physical configuration must be updated each and every time I switch between audio and movies. Too much work when it could be accomplished
automatically by WMP/WMC!
Thank you for your consideration of this feature request!

The ability of windows to better control audio channel output is definitely an issue that needs to be fixed. It's really basic in this day and age where everyone and there mother has more than two speakers (i.e. 5.1 or 7.1). I understand that certain media
players, or certain decoders/channel mixers can be a workaround for this problem. But that's not enough. Today, we have many different sources for audio that are not just files on a computers:
1) Video/Movie files on computers (played through media center, MPC-HD or other)
2) MP3s/audio (played through same)
But there is also:
HTML5, webpages, Netflix, Amazon TV, Flash players, silverlight, etc. etc.
Hence why windows needs an option at the level of windows audio decoder to better control channel outputs over LPCM-HDMI! Either Mirroring L/R outputs to rear/side speakers, or, formal upmixing algorithms like Dolby Pro Logic etc., applied before
outputting over HDMI (Note I am NOT talking about bitstreaming!)
This is a trivial problem using WASAPI or ASIO. Why has windows audio not been properly updated since Windows XP!!
Recently, HTPCs and Media Centers are becoming many households primary source of entertainment.
Examples of some issues:
1) With no bitstreaming at all:
- Configuring HDMI audio "Playback device" to 5.1/7.1, and,
- Using a software decoder/media player to decode Dolby Digital, DTS, DTS-True HD, or Dolby True HD, and sending the data in LPCM over HDMI to the receiver/soundbar
-> works totally fine for outputting 5.1/7.1 surround from those sources
-> windows (i.e. software) completely fails in any ability to upmix 2.0 stereo sources to 5.1 or 7.1, or even mirror L/R channels to rear/side L/R channel for more room filling sound. Both these options should be available - upmixing with Dolby or other
for videos and mirroring/doubling the channels for music/MP3s.
Instead, windows audio sends silent channels over LPCM/HDMI when playing a stereo source. This has the added awful effect of not even letting my receiver upmix/mirror the outputs.
Hence, we need the ability to duplicate (for audio) and upmix (for videos) the L/R channels in a stereo source to the Rear L/R and or Side L/R channels through windows audio "playback devices" configuration before outputting over HDMI-LPCM!
In the day and age of 5.1 and 7.1 speakers this seems like such a BASIC feature that is missing.Otherwise, so many of us with an HTPC in our living room as our main source of media can't play music mirrored
through all our speakers, or watch videos with upmixed audio.
HDMI is the new standard, so this should really become an option.
I've done a fair amount of research on this problem, and do not believe there is any solution short of switching to optical (which I do not want to do because it can only carry 5.1) or, buying a fancy receiver instead of a soundbar with discrete rears and
a subwoofer (which I have) to do the mirroring/upmixing for me.

T510 stereo audio connection options?
