Aja LHi analog audio i/o clipped

Is anybody run into this LHi audio problem? The audio in & output was clipped by Aja LHi card? It turn balanced to unbalanced audio. I'm sure it's not my setup cos' it dosen't change anything before & after. Is it the card failed? I've heard some of the LHi did.

Are you routing this audio through a mixer first? You really need to. Analog really needs a mixer.

AJA Lhi

I am using an AJA Lhi card in my Mac with PP CS4. I am capturing by component from a Sony HDV camera. I would like to speak with someone who uses this setup and can give me the configuration that they use that makes everything work. So far my problems are that the output monitor has vertical lines in the test pattern and now when capturing on the video. And audio is not coming through the mixer to the card...but it does show on the mixer and comes out the AJA card via the board to the studio speakers. I know this is just trial and error but it would be nice and cut to the chase with someone who has been there. I've been using compressed DVCPRO HD 1920x1080 8 bit as the capture codec. Any one one out there with the same set up?

is your camera a "Tape" camera or other storage format.
if Tape and not capturing Live (direct input to computer) there is no point to bringing it in any other way than firewire.
if not tape or you are capturing live then it may make sence. as you may be able to bring it in uncompressed.
(assuming your drives are up to it)

No output sound from output port/analog audio: Need help

hello, I want to connect my analog audio equipment to my iMac. I have done this in the past with my old G3. I have connected the RCA cables to a 3.5 mm jack and put it into the audio input port, which was what worked on the G3. When I open the sound page for input & output, on Output I can see the volume bar thing moving in relation to the sounds from mic, turntable, etc: all the analog audio things. However, there is no actual output of sound through the iMac;s speakers or a headphone. The output page is pretty simple so I am real sure I have all the rigt things checked, unchecked etc. Any ideas? Thanks.

I had what sounds like a similar problem to jazzzrat. i had my macbook setup to a stereo and it worked for over a year. suddenly no sound came out of the stereo. in my case, it definitely was a software setup thing.
plug in your stereo jack into the audio out port. then go to system preferences-->sound-->output. on there you should see, under "device for sound output": Name=Headphones, port=built-in output. (if you see name=built in speakers, you plugged in the wrong plug). Now go down to the bottom of the window and UNcheck the "mute" box, and make sure the volume slider is midway or more.
For some reason, mac allows you to mute the "headphones" and "built in speakers" selectively. we have no idea how that box got checked, that remains a complete mystery. but when we eventually found -- and unchecked -- the box, our stereo output came back just fine.
i hope this works for you. good luck and have a good new year.

How can i leave audio from one clip playing, while showing another one in i

i am editing a movie, using iMovie 08, and want to use sound for a clip in the video for the end credits. how can i do this?
just to be clear, i am not trying to add audio. i am trying to leave the audio from ONE CLIP playing, while viewing a new frame. thanks.

This is simple in iMovie 11 (drag and drop), but in iMovie 08, you can still do it.

How do I use just the audio from a clip in imovie? No picture, no video, just audio!

I want to put the audio from a clip at the end of the video. No video, just black screen

It will require a bit of a workaround. But it can be done. If you enable Advanced Tools under the iMovie Preferences (Go to the iMovie Menu > Preferences). Enable Advanced Tools by clicking the checkbox.
Now create a title with a black background by dragging at title to the end of the video on the Project timeline. Once the title is there, delete all the text on the title. Now drag that black background directly dead center onto the video clip just before the end where you want to 'blot out' the video and just have audio. When you release the mouse, you will be shown a pop-up menu with a bunch of different options including one titled cut-away. Choose this option. What will happen is the video will cut to the black video background you dragged on top of the video clip. You can set the duration by dragging the left and right edges out further to make it run longer. This black back ground effectively cover the video and will continue to play the audio of the underlying video clip.

How do I use just the audio from a clip without the video?

Can't remember how to use just the audio from a clip, without the video. FCP X can't select like FCP&

Edit just the audio into the timline.

Apple TV2 missing analog audio output for multi-zone system

Found out the hard way that most receivers can't support digital audio in multiple zones (i.e., Zone 2). Since Apple TV2 (ATV2) dispensed with any analog output, if you have a whole-house system that depends on mult-zone to distribute audio to various speakers, you won't be able to use ATV2 to stream music to anything other than Zone 1. The only outputs are HDMI and optical (both digital audio). I think I found a work around (which, of course costs more money) which is a "de-embedding" device from Atlona that takes HDMI in and splits out the audio to analog and passes the HDMI through to the receiver. The analog audio output then lets me connect to the analog in on the receiver so it can stream to all zones. I figure Apple just didn't have enough real estate on the new product to make room for analog, but it's a pain. Hope this helps someone. If anyone knows a better work-around, I'd love to hear it.

I have the same issue with a MacMini I use for music. My solution was to use an inexpensive optical splitter - one feed to the optical input of my receiver and the second to a DAC. Then run standard RCA audio cables from the DAC to the analog Zone 2 inputs.
Here is a link for a DAC
http://www.monoprice.com/products/product.asp?cid=104&cp_id=10423&cs_id=1042302&pid=6884&seq=1&format=2
They should have the splitter as well.

No audio in video clip in slideshow

How do I get the audio associated with a video clip to play in iPhoto? I have several clips taken on a digital camera--with audio--and have them imported into iPhoto. When I make a slideshow incorporating one or more of them, they play fine but with none of their own audio. How do I get their audio tracks to play in the slideshow? If I double click on any of the video clips separately before making a slideshow it opens Quicktime and plays the video and audio OK.

I am using iLife 2009 and do get audio clip associated with Video however it does seem to have some issues. Clips from one of my cameras (Sony - in avi format) work fine .. I can even choose an iTunes track or playlist and iPhoto blends the two.
However, I can not seem to get audio associated with clips from one of my other cameras - JVC (.MOD format converted to MPEG4).
The clips do have audio when played by itself in iPhoto however when I go to slide show mode, the audio disappears.
Still trying to troubleshoot ... will post if I am successful.

Audio dropout one clip only

I created a movie in iMovie 6.0.3 (project size approx. 3GB) and shared it with iDVD to burn a DVD. Very little extra added in iDVD for Theme, etc. so it should have been well within size limits of standard DVD-R. (I have successfully burned DVDs in iDVD for similar projects with the same brand of DVD-R media previously with no problems). The movie played with no audio loss in iMovie and on the iDVD preview.
I do have music running under the clips, and the only difference on the clip with audio loss on the DVD is that I had to extract the audio from the clip in iMovie to make an edit work.
On that clip of the movie when viewed in iMovie's timeline view I have my video visible on the top line with my extracted audio (from the video clip)on the middle line and my music on the bottom line.
When I burned the DVD and tried to play it back on my TV the audio was fine until the last clip of the movie -- where there was no sound at all. I tried importing from the Media pane in iDVD rather than sharing from iMovie with the same bad result after burning the DVD.
I have checked the forum, and while there are many similar issues no one seemed to have this exact problem. I did print out the linked article re: Updating iDVD to 6.0.1( I currently have version 6.0.3) and deleting encoded assets (I had plenty of space available on my hard drive) -- it didn't seem to apply to my problem, if I'm understanding those two issues.
I will try the Disk Utility fix, but I'm trying to make a deadline and have never created a DVD that way before.
Any ideas how to burn the DVD -- preferably with the iDVD theme and button menu if possible, but most importantly with the least loss of video and sound quality.

Thank you for the helpful response. I was able to deliver the DVD on time with a workaround.
Once that was done, I tried playing the DVDs I created originally on my friend's DVD player and they played perfectly!!!
Any suggestions out there -- other than I need a new DVD player
is there any way to confirm a DVD burned in iDVD will play on the majority of DVD players before I send it out as a finished project?

AppleTV audio out to old amp with only analog audio

I'm thinking about getting the Apple TV for both video and for playing my music on my home stereo system. I currently have an old amp with only analog audio capabilities, but the new ATV looks like it only supports digital optical out, and the digital to analog converters I've looked for seem pretty expensive. How can I get the audio from my music collection (iTunes) to play wirelessly through ATV through my amp?
I currently also have an Airport Express which I use for audio, but I was thinking of selling that and just using the ATV since the ATV can essentially do the same thing as the AX with added video benefit. I've seen some threads on streaming audio from the ATV to the AX, but do I really need both? Seems like there should be another way.
I was thinking of connecting the ATV to my TV via HDMI cable for audio, and then using an analog audio out from the TV to my amp. But, if I'm correct, that would only provide me with sound coming from the TV. It wouldn't give sound out from iTunes, for example. Is that right?
Are there any other options?

Followings are my observations in audio streaming with Apple TV 3 and Airport Express through AirPlay protocol:
-- Apple TV 3 come with only digital audio outputs through HDMI and optical SPDIF outputs. If you connect optical link from the optical output to optical input of any DAC and HDMI cable from the HDMI output to HDMI input on TV set, audio output will be transmitted through both digital outputs. Thus is is not necessary to turn on TV set unless visual feedback is required. There is no audio analog line output for Apple TV 3.
-- AirportExpress come with single combo mini jack (digital + analog) for audio output regardless of old/new models. You can connect either digital optical link (with Mini/Toslink adaptor) to digital input of DAC or analog line cable (inferior) to analog line input of amplifier. When analog line is used, digital-to-analog conversion is done by DAC built into AirportExpress for which do not expect quality is as good as most external DAC models. What do you expect from a single-chip DAC implementation vs standalone DAC models cost few thousand dollars ? Moreover analog line is susceptible to interference more than digital line.
So the decision to use Apple TV or AirportExpress, analog or digital transmission for audio streaming depends on whether you need WiFi base station features of AirportExpress to establish wireless network and quality of your audio system to justify all-digital audio transmission. Followings are what I use in audio streaming from iMac/iPad mini /iPhone 5 to audio system in living room. Quality of audio output is comparable with Sonos Zone Player as audio source.

Splitting front & back panel analog audio

Hello,
I'm new to arch linux, and I'm trying to reproduce what I was doing using Windows: I have my headphones and my speakers always connected to my computer, and I switched output "by the OS" whenever I wanted to.
Here, in arch linux, I see I have (in gnome sound panel) the two analog outputs I'd like to switch to when necessary: headphones and line-out.
However, both of them seem to output audio only to headphones.
I've tried different things:
- If I remove Auto-Mute, I can have the audio output on both front and back panel. However, if I re-enable it, I just have front panel analog audio
- I've tried this, without impact: https://wiki.archlinux.org/index.php/Pu … ont.2Frear
I guess it's not a real problem with pulse audio but more with drivers. However, I don't know how to fix it.
Would profiles help? http://www.freedesktop.org/wiki/Softwar … /Profiles/
I doubt it, but if it's the way to go, I'd like to learn about it.
Here is info about my hardware:
http://pastebin.com/gnpw0bF4
And about my pulse audio sinks:

MSC wrote:Based on your description, I assume your speakers are plugged in to the back panel and your headphones are plugged in to the front? And you're trying to get output to one or the other, but not both?
Indeed, they are both plugged at the same time, and I want to select my "unique" output.
MSC wrote:One thing you could try is muting the headphone output before switching to line out in PulseAudio, or vice versa. See also if you can control the volume independently - can you turn the headphone volume all the way down without also silencing the speakers?
I can't control them independently. Turning the volume down for headphones silences the speakers.
MSC wrote: Failing that, is auto-mute the only setting your card provides, or are there others? IIRC Gnome hides a lot of switches by default; you can see the full list of settings by running alsamixer in a terminal. You should also look over the ALSA page on the wiki if you haven't already. My guess is that it's not an issue with the hardware itself, but rather some setting that needs to be toggled.
I don't see much more in alsamixer... I've tried toggling everything up/down, the only way to output on the speakers (back panel) is to switch Auto-Mute on/off.
In the alsa page, I only see that part as relevant: https://wiki.archlinux.org/index.php/AL … g_speakers However, it's for HDMI, which is not the case here.
Maybe changing alsa model?
I'm kinda lost...

Analog audio to optical connection

I am trying to connect an analog Bose Cinemate home theater system to my new HDTV. The TV does not have an analog audio in, only a SPDIF (optical) in connection. Is there a way to convert the analog to the optical connection? I was told there is a converter for that, but I have not found one. Thanks for your help.

You should be looking for outputs on your TV, not inputs, as all TVs have analog inputs.
Please post the make and model of your TV set.

Detaching audio from video clips

Hi
After trying the standard 'detach audio' button I cant seem to find a way to completley detach audio from a clip in order to hear the track I have added to the clip. All I can seem to do is turn the volume right down, and inturn still able to hear it, which is proving annoying!
Any ideas would be appreciated!
Thanks

Thanks for your reply Geoff,
I basically have a soundtrack 3.28 minutes long which I want to be the only noise thats playing throughout my interchanging video clips, so I would like to completley move the audio from the all of the indivdual video clips that I am adding in, I thought the 'detatch audio' button would be the one for this, but as I continuously play back bits of the movie to prefect editing I can still slightly hear the sound from the individual videos that I am adding?
So frustrating, but Im sure thats its something real basic that I am missing.....

Optical Audio - Analog Audio Adapter?

I have been thinking for a while about buying an Apple TV.
One of the main reasons I want an Apple TV is for streaming music through the Apple TV into my stereo system WITHOUT having the TV turned on.
So this means I need to use the Optical Audio port to go straight into the stereo.
I have a Kenwood XD-551 stereo system which is reasonably old and only has Analog Audio input. That means I can't connect an Apple TV to the stereo using an optical audio cable. Is there an adapter I can buy that connects Optical Audio to Analog Audio?
I know I can stream music to the speakers through an AirPort Express (I have a 3.5mm to Analog cable), but I want an Apple TV also to stream HD Movies and TV Shows from iTunes, as well as AirPlay Mirroring from my iPod Touch.
My current set up:
TV --- 3.5mm jack to Analog Audio Input --- Stereo
My intended setup:
Apple TV --- HDMI --- TV
Apple TV --- Optical Audio to Analog Audio Input --- Stereo
I REALLY NEED A SOLUTION TO THIS OR ELSE I MAY NOT END UP BUYING AN APPLE TV

I am also looking for a exactly a similar setup.
streaming music through the Apple TV into my stereo system WITHOUT having the TV turned on
@alexei Ok, so this solution works with you. just to understand the setup,
you connected the apple tv's 'optical digital-audio port' to a DAC using which kind of cable ? links from amazon or other websites will be very useful.
Output from this DAC, you connected to the speaker via 3.5mm jack, correct? again a cable name (both ends) will be extreemly helpful.
With this when you airplayed music on 'apple tv' via itunes just the audio played on your speaker, correct? assuming your TV turned off during the music play.
And when you airplayed video/movies on 'apple tv' it automatically played on your TV.
Just wanted to know, you see only one airplay configured on your iphone/ipad correct ?
If this exact setup works with you..then bingo..I can go ahead buy all those stuff. If you have a different set-up with which you play music and video sepeartely using apple tv then please do share..
Your answers to these quesions will help me to decide if I need to buy Apple TV for music(which is equally important) and watching movies. And the invetsment dosent stop there..therz DAC and cables.
Thanks!
PS: I know I can stream music to the speakers through an AirPort Express, but want to go for apple tv.
