Mpeg converted to MPEG-4 Has no sound

I converted these MPEG files into MPEG4 and they have no sound, i have the 6.0.2 update on the iTunes, and 1.1 on the iPod. Can anyone help me out here?
The original has sound and the converted dosent. Took 1 day to convert all the movies

What software was used to convert the files. Not QuickTime or ITunes (Which also uses Quicktime) I hope?
Read this about the limitations of quicktime and handling MPEG Files.

Why doesn't Quicktime Support MPEG-2 with AC3 sound?

Last summer I bought a Mac Mini so I could use iMovie and iDVD to convert and edit my 20 year old VHS tapes of family events to DVDs. This Christmas I got a Samsung DVD Recorer-VCR unit that easily copies VHS to DVD in MPEG-2 format with AC3 sound.
So, I'm all set to use my Mac Mini and begin my family archives project - or so I thouhgt. I found that Quicktime and iMovie don't read MPEG-2!! Then I was relieved to find that there is a plug-in that works with Quicktime Pro that will read MPEG-2. I spent the $50 to download these 2 programs and sure enough Quikcktime Pro will now read the MPEG-2 files from my Samsung unit. However, there is no sound!!!
Is Apple purposely making it impossible to do what I'm trying to do?
Why doesn't Quicktime or iMovie support MPEG-2 with AC3 sound?
Is there some other sound format that is normally used with MPEG-2?
Why would someone create software that reads movie files but doesn'rt read the sound that goes with them?
If I can't hear my little girl sing on these movies, then this whole project is a big waste of time and money!!
I hope someone from Apple can give me some answers.

FWIW, MPEG is a distribution format, not an editing format. The best way would be to convert VHS to DV, edit it in iMovie and burn THAT to DVDs.
Sure, MPEG is a nice compressed format taking much less space than DV but the compression takes away quality.
IMO the best approach with MPEG source would be to edit (yes, it CAN be edited) it with apps like MPEG Streamclip (very limited editing features) or Capty MPEG Edit EX (more features) and author the edited MPEGs via apps like Toast, DVDSP, Capty MPEG Edit, Sizzle etc. THEN you won't lose any quality (unless some of the GOPs have to be re-encoded, that is).
BTW, unlike QT Player, MPEG Streamclip can play also AC3 or PCM audio in MPEG files.

Mplayer has sound, but Smplayer has no sound?

heya,
I have a Lenovo X200 tablet, with Arch64 installed on it.
I have Mplayer SVN-r31040-4.4.3 and Smplayer 0.6.9 (SVN r3447).
Previously, both of these worked fine, However, recently, after a Pacman upgrade, when I attempted to play a movie, Mplayer seems to play the movie with sound, but Smplayer has no sound at all.
I checked the output from Smplayer:

Any ideas on what's going on?

heya,
Aha! That worked .
I changed from OSS to Also, and it works fine now.
Any idea why it changed like that? Could an update have caused it?
Also, there were other ones, like "alsa (0.0 - HDA INTEL)" and "alsa (0.1 - HDA INTEL)". Not sure what they were there for.
Cheers,
Victor

Videos converted to ipod format have no sound

I just got a new nano and I have some videos I'd like to synch to it. But when I have iTunes convert them to ipod format I lose the sound. How do I fix this??

I can't make a good recommendation since I avoid Windows like the plague.
As a Mac user, I can only relay info that I have read on these forums.
I believe users have had mixed results with Videora iPod Converter. Some people rave about it, some people hate it.
I'm not too sure what else is out there.
I'm sure a Windows user will post here soon with some other recommendations.
EDIT: Just noticed that MPEG Streamclip has a Windows version now. You might want to check that out.

My iPod touch has no sound when I play music or use the iPod touch at all. Yes, the volume in the "sounds" is all the way up. It has not been dropped or gotten wet. I turned it off and on. now what?

My ipod touch (4th generation) has no sound. I have turned it off and on.....I have the volume up in the "sounds" area. When I push the side volume button, there is no image that appears in the screen that shows that I am either raising or lowering the volume. Do I need to just rest the ipod touch as a new device? Or is there someting else I can try?

And, now when I do press the side volume buttons, the image appears but with the words' "sound effects." what does that mean?

My 4s has no sound on most outgoing calls. i constantly have to turn my phone off and on more than once a day to get it to work. how can i get this fixed?

My 4s has no sound on most of the outgoing calls i make. It will ring the other phone I am calling but I cannot hear it nor can they hear me when they answer. Its just dead air but my phone timer is in use. How can this be corrected?

It's very possible that you have stuff running in the background that you don't even realize you have running. For example the default is for all notifications to be on and you usually need few to none of them.
That said, while an iPad can run warm, too hot to handle isn't right. ALso you should get about 10 hours....depending on what you're doing of course. If you're doing processor intensive stuff, like gaming and videos it can drain faster and generate more heat.
I would say if you have an apple store near by, make an appointment and have them check it out. If the issue is due to what they determine to be manufacturer's defects then it could fall under the warranty. But that's up to the store to determine.

My iPod touch has no sound from music and videos help please

My iphone 5 has no sound

My iphone no longer has any sound at all through the speakers or the headphone. I can't hear ring tones, any tones, music, videos, use of the speaker phone during phone calls, nothing. This phone is only 2 months old and I just did a software upgrade and that didn't help.

i have a macbook so sometimes this happens to it as well. what i found to help a lot is if you stick a sewing needle into the headphone jack. similar to the macbook, i feel like the connection thinks it's still plugged into something (notice that when you're adjusting the volume it says volume (headphones) not just ringer). unlocked, and while adjusting the volume, probe around with a needle, pushing it as close to the center all the way in. you may have to do this a few times. the first time i did it it worked, but went back in a few seconds. i did it again and it worked!
no need to drive to apple!

This happened to me too, so I took it to the Genius Bar at my local Apple Store. They said it was coincedental and the speaker needed to be replaced. They did so and the problem was solved!

Brand new iMac 27 has no sound

A buddy just got a brand new iMac 27, out the box last night. It has no sound.
He went to Systems Preferences and the Sound page provides no solution. Nothing can be clicked.
I know the solution is probably insanely simple, but cannot figure it out.
Help please.

The simple solution is take it back to Apple and ask them to fix it.

HP pavilion dv6000 with windows 7 64 bit has no sound after disassembled.

Hello there,
I have an HP Pavilion dv6000 and after i disassembled and reassembled it to clean the fan, the lap top has no sound. In the device manager an error on ''PCI bus9, Device 9, function 2 & 3'' was appeared but after i installed new drivers the errors was fixed and it was written that the device was working properly. but unfortunately the device is not working properly because i stills have no sound. I also disassembled and reassembled for second time to find out if the problem was minor like an unplugged cable but everything was completely fine. Operation system: Windows 7 64 bit. Can someone please tell me what to do?

IOS 7.0.4 on iPhone 4S has caused sound to go on and off? Has anyone else experienced this? Is it fixable?

Also the animation of the bell with a sound bar underneath is not working properly. Sometimes it pops up with the bar under the bell and sometimes the bar is missing and just the square with the bell is all you see. The side sound buttons are still functioning, just an animation glitch. When head phones are plugged in there is no change in the strange sounds going in and out. Videos are the worst and not only do they not play sound but thy also pause themselves??? The typing has intermittent sound. I have hard reset and rebooted my phone about 8 or 10 times with only temporary relief. I connected to iTunes and toatlly reset everything once, still no change??

Are you connected to wifi?
If you can't do it on the phone, you can most certainly do it via itunes.

When I take my phone off charge in the morning I get an info box on the front which has the sound trumpet icon with a line through it and the word Mute. The only way to get rid of it is to reboot the phone any ideas as to how I can stop this happening?

Hello cor-el, thanks for your reply. I changed my settings for downloads to desktop and it has appeared on there. When I double click I am asked which program I want to open file. I click firefox and another box "opening install" says I have chosen to open the file which is an application and do I want to save it. This is the only real option so I press save file. I get a box saying this is an executable file which may contain viruses - do you want to run. I press ok and the final box showing C drive file name and desktop appears stating application not found.
This happens the same whenever I try to install.
To my untrained eye the application is not being recognised as an application and I cannot work out how to get it to do that.
My plugin is still showing as out of date.
Is there anything you could suggest. Thanks for your time.
