Audio/Video Output Splitter/Selector Help
Hey guys, quick question:
I use my late 2009 mac mini to run my DVI monitor most of the time but sometimes when I'm watching downloaded stuff I switch it over to my LCD TV which means I have to switch the display cable in the back and the stereo audio out cable from my computer speakers to my TV. Is there such a device where I can just switch between the two without having to juggle the cables every time? I know they make DVI splitters but what about DVI and audio?
Thanks in advance!!
Take a look at the Belkin website. I have one of their KVMs for switching between VGA, USB and audio between my PC and Mac. They may have something for DVI too.

Audio tracks output splitter method? or splitter plug-in? PLEASE Help
Fellow Logic-addicts,
I am scratching my head around a problem.
I already use a lot of external hardware processing, and nearly always as inserts
processing(compressors,eq,analogue filtering)
Until sometime ago I did the same for using more send-return type of fx like
reverb/delays/modulation etc....
Thus I had to duplicate a dry audiotrack and process it, and bounce then blend in with the other track.
In a recent project I mixed, I ended up with some sessions with a leadvocal track
and 5 copies of this track all processed through various fx like short reverb,short delay, long delay, doubler etc..., because of using hardware fx.
I wonder if it's possible in Logic to insert the hardware fx on a bus, so I could simply use the aux sends on the track's channel strip to send to that bus and to avoid piling up identical audio files in a Logic project, which also is clumsy
in the workflow, because when I apply hardware fx to a lot of tracks there are doubles/triples everywhere and it gets confusing and too crowded?
Other possibility, I've been searching like a madmen for years for an audio track's output splitter plug-in(like Spider in Reason), but I have found NONE
in the AudioUnits realm.
Does somebody know about such a plug-in to work in Logic?
I still don't understand why the Apple-developers didn't think of including such a plug-in, because it could allow amazing routing possibilities, like in this case, you could send the audio track to the main output(1-2 or whatever)
BUT also to alternate hardware outputs, so you can use a hardware reverb unit, + a hardware delay unit etc...to which the audio track is being sent , and then you could blend the results back in Logic more easily.
Or more: you could even avoid copying tracks for sidechaining as you could use one track as is to main outputs but also connected to the sidechain input of other tracks processing, wich would make this also easier.
Or what about outputting and grouping drum-tracks(kick-snare-hh-etc...) to multiple busses so you could have a very flexible setup for parallel processing, with many
more sonic possibilities= drum-group going to a bus with hard-compression, while another goes to a softer compression, and a third one a distortion/beef bus with tape/tube processing, then you could all blend those tracks with faders, like on a real console and not piling up inserts on one bus, wich is more limited sonically, especially if the processing you use doesn't have a dry/wet knob.
If any of you sees a better alternative, or method to achieve what I want in Logic, or want to discuss that topic and chime in, be my guest.
I am not an expert of Logic, so you Logic geniuses= rise and shine!
Thank you very much for your advice
Best Regards
BiggnikWow - long post to say "can I use hardware boxes as inserts?" and the answer is yes, and you have been able to for a long time.
I don't know why you're doing some odd "duplicated track" thing... weird...
So, for inserts of regular channels, just stick Logic's I/O plug on the channel. Tell it which audio output you want it to send to, and which audio input to receive from. Patch up the appropriate ins and outs on your interface to your hardware box/patchbay/mixer/whatever and bob's your uncle.
You can also do this on aux channels, so if you want to send a bunch of tracks to a hardware reverb, you'd put the I/O plug on the aux channel you're using in the same way as described above. Now simply use the sends on each channel you want to send to that aux (and therefore hardware reverb).
Note you'll need to have software monitoring turned on.
Another way is to just set the output of a channel or aux to the extra audio outputs on your interface, and bring the outputs of your processing hardware back into spare inputs and feed them into the Logic mix using input objects.
Lots of ways to do it in Logic.
And no duplicate recordings needed...
I still don't understand why the Apple-developers didn't think of including such a plug-in, because it could allow amazing routing possibilities, like in this case, you could send the audio track to the main output(1-2 or whatever) BUT also to alternate hardware outputs, so you can use a hardware reverb unit, + a hardware delay unit etc...to which the audio track is being sent , and then you could blend the results back in Logic more easily.
You can just do this already with mixer routing alone, no plugins necessary. -
Does new Zen player have audio/video output to telivis
Hi there,
Does anyone know if the new Zen Player had video out for television? I know the Zen vision W has, but what about the Zen player?
Many thanksno it doesn't.

I have an HDMI connection to the receiver and on to the TV - but there is non audio from my Apple TV. Not for movies, music, YouTube etc. I have checked all of the connections and the video is xlnt. Have also toggled thru all possible Dolby/Audio combinations in settings. Help! Any suggestions?
Hello again Parker -
The basic setup is Digital Cable Box, DVD Player, Denon Receiver/Amp and TV Monitor. To that I added the Apple TV. The Receiver only has two HDMI IN slots (one for cable and one for the DVD) and one out to the Monitor.
[I bought a switcher to toggle the DVD and the AppleTV back and forth but just disconnected the DVD to simplify when I ran in to trouble.]
So now I have:
HDMI from the Cable Box to the Receiver
HDMI from the Apple TV to the Receiver (in the old DVD slot which always worked well)
HDMI from the Receiver to the Monitor
RCA's from the Receiver to the Subwoofer and the other speakers
In addition I have some backup connections:
S-Video, Optical Audio and L/R RCA's from the Cable Box to the Receiver
S-Video from the Receiver to the Monitor
Wait - JUST FOUND IT!
By going thru the excercise to track all of the connections per your suggestion, I found an anomaly when I switched Receiver sockets for the HDMI links. The video moved but the audio didn't. Turns out the monitor was using the optical audio feed from the receiver. So I disconnected the optical audio and the monitor automatically switched to the HDMI audio feed! Looked promising...
So I first connected an optical audio feed from the ATV to the receiver - Audio! Then I pulled it, but the audio didn't switch to the HDMI feed. It stopped. Would be OK if all I was going to use is the ATV, but I need the DVD player too and I can't use a switcher to toggle between them if I have to unplug the optical audio each time.
This is becoming a career! Any suggestions?

I am trying to use imovie and i have never had this problem before. All of my videos are completly grey and when you try and play them all i get is a black screen but i still hear audio. Can you please help and tell me what i need to do. Thank you
Make sure all of the videos used in the project that is having that problem are from the same event. If they are from multiple events, move them all into one event.

Video output from iPod Touch (2nd gen) via AV Component Cable (no audio)
Hi, I'm trying to output a video from my iPod Touch (2nd gen) to my TV via a AV Component Cable.
Unfortunately the audio doesn't work, I'm sure they are all connected into the right places.
The video works, but I get no audio. (And no subtitles when closed caption is on)
Here is a link to an image of the TV connections from ImageShack:
http://img707.imageshack.us/img707/7280/img0204y.jpg
At the top left of the image, are what I assume to be the red and white audio ports, highlighted in red.
I plugged in the red and white audio connectors into those ports.
And towards the bottom are three ports, green, blue and red, also highlighted in red.
I plugged in the green, blue and red connectors into those ports.
I changed the input of the TV to Input 2, I see the video for the movie I'm watching on the TV but no audio. I tried multiple movies.
I've also tried changing the video output from PAL to NTSC and back again, turning Widescreen on and off and turning Closed Captions on and off. I also tried plugging in the red and white audio connectors into the row of ports just below the green/blue/red row, to see if that made any difference, and it didn't.
I tapped the bottom left button of the iPod Touch when plugged in to the TV and playing video and it came up with an option that was selected called ~"Audio Source: English (Stereo)"
Any idea's? Thanks.Resolved... ThankYou

Video Output ALWAYS dictates Audio Out!!??
I have a Black Magic card in my system. To save space on my working monitor, I'm viewing my movie from the output of my Black Magic card on an external monitor. However, the audio is also being sent to this monitor. I'd like to do my mix with my headphones, and not on the crappy monitor speakers, but every time I change the video output, the audio always gets sent to the monitor. I have to watch the video in a window on my monitor to be able to listen over headphones, which is a waste of space. Why can't I control this?
In my audio prefs, audio output is set to built-in output.Weird, I have both setup, Windows 7 with Lenovo Graphic Driver and Windows Server 2008 R2 with Nvidia Driver, both have audio output.
Try to go to Device Manager to see if there's anything called Nvidia High Definition Audio, for me, I have 4 same devices. If there are unknown devices, install it manually with inf files.
Best Regards

Please, help with Live Audio/Video example from jmf solutions
Hello,
I�m desperate looking for a solution for a particular problem.
I�m trying to feed JMF with an AudioInputStream generated via Java Sound, so that I can send it via RTP. The problem is that I don�t know how to properly create a DataSource from an InputStream. I know the example Live Audio/Video Data from the jmf solutions focuses on something similar.
The problem is that I don�t know exactly how it works, os, the question is, how can I modify that example in order to use it and try to create a proper DataSource from the AudioInputStream, and then try to send it via RTP?
I think that I manage to create a DataSource and pass it to the class AVTransmit2 from the jmf examples, and from that DataSource create a processor, which creates successfully, and then find a corresponding format and try to send it, but when i try to send it or play it I get garbage sound, so I�m not really sure whether I create the DataSource correctly or not, as I�ve made some changes on the Live Audio/Video Data from the jmf solutions to construct a livestream from the audioinputstream. Actually, I don�t understand where in the code does it construct the DataSource from the livestream, from an inputStream, because there�s not constructor like this DataSource(InputStream) neither nothing similar.
Please help me as I�m getting very stuck with this, I would really appreciate your help,

I recently formatted a friends lenovo laptop, to the same operating system (win xp sp3), and I can't seem to properly install her audio and video drivers.
All the product/model numbers are
3000 n100 0768 09u
i think 0768-09u is all that matters
i tried all the drivers on this page:
http://www-307.ibm.com/pc/support/site.wss/product.do?subcategoryind=0&familyind=303747&brandind=10&...
still no sound, and proper video output. wondering if anyone can clue me into what I could be doing wrong? or maybe how to locate the exact drivers that came with that model computer.
thanksThis is the proper drivers page.
It's possible that the driver is extracted to a local drive and not executed for installation.

Hi, Excuse my English, I'm using imovie 11, I want to delete a clip video at the end of the project, but keep the audio over the fade to black, everytime I delete the video, the audio is also deleted, please help!
I assume you are trying to end the clip/project with a fade to black, or something that just doesn't cut so instant.
One thing i'm thinking you can try is to Add a "Transition Clip" to the end, and try your first method. (with Detached Audio + Delete Selection. (Yellow highlight was deleted selection) Do you need something to end like this?
If you can, put screenshot up (Shift+Comm+4), if i'm not on the right idea. It seems like an easy fix, with a few ways of doing it. You can also add a blank image to end project, sub titles or Add,Cutaway fade +Opacity adjust. -
