OS X :: AVI Files Playback With No Sound
Dec 20, 2010
I am new to this forum and have only just brought a MacBook. I transferred video from my mini dv camcorder to my pc using firewire. The data was recorded as an avi. These avi videos play fine my on pc (in windows media player and real player-with sound). However, on my mac, the video is displayed but no sound. The video is played, but there is no sound (just crackling). I have tried realplayer, quicktime, divx and vlc. I have downloaded perian, but this has made no difference. In quicktime, the video is displayed, but no sound. In VLC, there is video, with crackling sound. I have about eight videos and none of them have sound on the mac.

I wanted to use a lavalier mic for a video conference, but when I plug the mic in to the MacBook Pro (late 17" 10.9.3) I get no playback from Garage band or other recording apps until I unplug the mic. I have tried a Rode lav and a Sennheiser mic for DSLRs. Am I missing something, or is there a problem with the computer?

Since a couple of days I'm noticing a popping sound during audio playback through my external speakers. That means when playing back a video or music through iTunes, basically always when there's audio playing. I'm in the process of figuring out if it also happens on my regular integrated speakers.
My MBP is the recently released 15" Core i7 model. Only thing I changed is I added an Intel SSD.
Any thoughts as to what it can be? Or where to start looking for a solution?

The output sound is suddenly really quiet. I have to turn it all the way up to hear anything all all sometimes. My iTunes seems fine and my notification sounds work, but playing videos is seriously sketchy (from YouTube, Hulu, Facebook, wherever).

I have a 2 1/2 year old MBP running SL. I recently have been having issues with the dvd drive. I have been trying to convert avi files to dvd. I have tried two different avi files and two different applications (idvd and burn). They do the conversion of the file, but when the disc is completed there seems to be files on the dvd but it cannot play. Sounds like the drive starts up, spins the disk, stops and repeats this till I eject. I get a beachball on the screen as well. Now I have tried known good DVDs and they play with no issues and games like the Sims 3 seem not to have an issue with playing in the drive. I was just trying to figure out if this is hardware related or software (apps or the files I am trying to convert) before my Applecare runs out.

I'm looking to digitize my DVD library and be able to play back the files with surround sound. The actual digitization process isn't the issue here, but I want to know how I can go about playing back the files and not losing the surround sound. I'm planning on buying a new mac mini to do this and connecting a mini-toslink cable up to my receiver. What application should I be using to get the audio playback?

I am having a problem playing some mp4 files through Quicktime. When the video is played in Quicktime (or Pro Presenter 4), portions of the video turn into distorted white blocks that move with the video. It doesn't continue throughout the whole video, but I can't discern when or why it only affects certain portions. It does it every time at those places in the video. I downloaded VLC, and the same exact file plays perfectly fine in VLC and on other computers through various programs. I have only seen this problem on this computer.
Is this a codec issue? How do I fix it? The files in question are mp4 files using h.264 video and AAC audio at 1920x1080 resolution. I can play other mp4s using h.264 and AAC without any problems.
I have only had this problem with one of the companies that we periodically hire to produce videos for us. I'm guessing that it has something to do with the way he encoded the video, but I have no idea what the problem is. It's probably not his fault if it only distorts on this one computer.
Here is what the white block distortion looks like:

I have the most recent iMac and Macbook Pro on my home network. I'm sharing files between machine and both are using WiFi through a Linksys Router. I have video files (avi's) on one machine that I'm playing on the other machine. The files play no problem but their is an intermittent halting. I probably wouldn't call it a stutter exactly. It stops playing and the screen halts at a particular frame, and then after a bit it starts playing again. I'm wondering if this is normal behaviour or if I have something setup incorrectly on my network. Also, I'm wondering what the solution to this is other than copying the files from one machine to the other.

I've downloaded shows from itunes, they are on a hard drive. Before, when I chose to play the file on itunes, it used to simply link (or source) the file from the hard drive, but recently it started copying the file to the iTunes folder (on my computer). This is very frustrating because I simply don't have enough space in my computer to have contain all these HD videos. Is there any way to have it linking to my files rather than having it copy over?

iTunes, Mac OS X (10.6)

Anyone know of a sound converter for OSX that can convert old sound files from OS 9?
These are old-school ones that you double-click and they play. The file extension is missing on them, so I'm not sure exactly what they are, but I've had them for ages!

Just bought the new mac mini with HDMI out - 2.66Ghz, 8 Gb RAM, 500 Gb HDD
A lot of mkv or avi files I playback appear pretty choppy in VLC - my primary app for watching movies and tv shows.
I have a Drobo with two 2 TB SATA drives where I store all my stuff and which is connected to my mini via firewire 800.
I've tried playing the same video back from both the Drobo and from the internal hard drive, to see if the choppiness was on account of the external drive or not. No difference really. A choppy video remains choppy from either place.
It's pretty strange because some 1080p videos play just fine, with no choppiness whatsoever, while other 720p videos or even standard definition divx files are still choppy.

I need a basic app (not some amazingly expensive app with a million functions) that lets me edit an .MP3 file and cut out part of the middle, the ends, and export it. Quicktime X would be perfect, but you can't edit out the middle.

I have had my Mac for almost a year! However, this morning when I went to go on it, the itunes music files I normally play aren't playing with sound. It shows that they are running their time but no sound is coming out. The speakers are not on mute, the volume is turned up and I know the speakers aren't blown or anything because I can hear the "bleep's" telling me I am changing the volume up and down.

If any of you recall, in System 7, you could double-click a sound file and it would just play without launching an app. The OS itself was capable of playing sounds, like system sounds or even music files (you could also use QuickTime). This was pre-iTunes. I miss those days. The other day, I was trying out some sound effects, and double-clicking them launched the behemoth bloatware app, iTunes. Of course, I could pick another app, but I would prefer no app at all, i.e., system-level, ready-to-eat sounds; just click and it plays. Does anyone know of a system-level plug-in or background app that works in this way? An analogous system function would be clippings. Double-click one of those and it just pops up; no app launches. This is how System 7 worked, and I sorely miss it. I use sampled sounds a lot, and I just want to click on them to quickly hear what they sound like in that same simple way we once could.

I have 12 Videos in .mov format that I saved from .wmv format using quicktime and flip4mac. I have also tried saving them as AVI and same result.
Here's the problem, when I put them into iDVD and save as disk image to check, the videos are there, but no sound. I tried also burning them to DVD, using a maxell DVD-R 16x, and all the will come up on the dvd is the title menu. Movies will not play on my macbook or in the dvd player on TV. I tried using the .avi format but there still was no sound, and the movies were really choppy.
if i try to use iMovie, it will not even import these .mov files (doesn't let me click on them to import)
is there another format i need to export to, or change some setting to get the sound in my project, and get the movies to play have i burn them?
All the movies are approx 1hr long except one, and I was using the best performance setting putting 2 movies per dvd.

have been making movies with imovie for the past few years. Today I imported from my camera, could see the clips moving in imovie when being transported, but when I tried to edit the clips, all I could get was a screen frozen with a picture, no movement, but could hear the sound. Then when I tried to open an already saved imovie (that had already been burned to iDVD successfully), the same thing happened.

This started happening randomly earlier tonight, and I haven't managed to find a fix just yet.I was encoding a video file for quite awhile (I don't think that parts important, but I thought I'd include it anyway) and then I tried to play a youtube video. I noticed there was no sound, so I tried to up the volume using the Volume Up key on the keyboard. The volume visualisation appeared on the screen like normal (albeit a bit laggy), but the sound still didn't change, neither did I get the usual 'click' noise you get when you change the volume.I went looking into the sound options in the system prefs. only to find that the Output Sound device was headphones. For a test I plugged in some headphones to see what happened and, low and behold, the Output Sound device changed to the Internal Sound and my speakers were working again, but only with the headphones plugged in.

I currently have some good headphones and use the front jack. How do I hook up the three speakers? Do they all plug into one jack in the back? And what about the subwoofer, does it need a special jack.Final question: is there something I could purchase to improve the sound that wouldn't be too expensive? I.e. is there some USB extension or sound jack item that I can buy, which will improve sound performance, and plug the speakers into that?

When surfing the net (like right now) or just letting it idle, my hard drive makes a slight "clunk" sound like the HD arm is hitting the edge of the case (or maybe starting up and shutting down?). There seems to be no loss of performance. I did a disk verify and everything is OK. Should I be concerned?

I just bought an iMac 24" 2.8Ghz Dual Core, 2Gb RAM, 320 HDD. This nice iMac has been with me only 2 days and the problems already started. I don't know why when I play a song either in iTunes or in web(audio streaming) the audio suddenly changes. It's as if you applied an EQ and removed all the low frecuencies and after a few seconds the sounds returned just as normal. When this "auto EQ" happens, the sound becomes "brighter" (I hope you understand what I am trying to say) but just as I said, after a few seconds, the sound is played normaly. I am running Mac OS X v 10.5.2.

I have a person that sent along this video and it concerns me that a hard drive would make such a noise. It's unlike anything I've heard in a drive. He claims the original owner installed a new Seagate 7200rpm in the book, and that it mostly happens when loading a web-page on Safari.
Every time I look up "hard drive click" I get the SMS triggered "tink" but this notebook is not in motion and instead makes a "ca-chink".

I'm pretty new here, though I posted over a year ago here with a few questions as a beginning switcher. My switch completed in Christmas of 2005 with a late '05 Power Mac G5 Dual-Core 2.3GHz with 1GB RAM and 250GB HDD. I decided to get another monitor and it is a Sony 19" LCD one. I also didn't get any speakers since I used headphones a lot at the time. I recently decided to start using speakers. So temporarily, I am using the Altec Lansing BX1120 2.0 Stereo speakers from Walmart for only $15. They sound great but I would like 5.1 surround sound to watch my DVDs (and to soon upgrade to BluRay & SACD/DVD-A; but that's for another thread later on). Before I go on, I would like to ask questions and provide facts with what my 'puter has. My specific products I'm looking for is at the bottom of this message.
