Easilyupdate tutorial and how-to videos without re-recording the voice-over. Extract the audio file from your original video, then attach the voice-over to your new screen recording or video walkthrough.
The problem with that is that you will be making the video quality worse by re-encoding it with no audio. It would be much better to do this in Avidemux which lets you directly swap or remove the audio without re-encoding the video.

One reason is that I have found that some video sources produce output with the audio up to 500ms out of sync with the visible action, so all of my video recording sessions begin with a synchronization clap.
hi Mox601, I do not believe so. Its a per-clip job to detach all clips. If the clip starts as one long clip you can detach befroe you start cutting, that might help depending on what you are trying to achieve.
I've received Inspiron 1420 Vista 32 from my brother as a gift. He had it before and said that he had sound from the moment he purchased, but later (he doesn't remember when) the sound just disappeared. I reinstalled the system to the factory settings (pressed F8 and then restored from the recovery D: disc). No audio through internal speakers. However, I can hear everything if I connect my headset through audio-jacks. I reinstalled drivers from the "Drivers and Utilities" DVD. Same result. I downloaded two drivers from Dell download page (R157031 and R167846) and tried one by one. Same thing. I ran diagnostic test (F12>...>System>Custom>Audio Analog test and can hear the sound through the speakers. I tried to delete the driver and restart computer, so Vista can catch the new hardware and fix the problem, but after new hardware was found, Windows driver installed, result is the same. I checked if the speakers are muted and they were not. I checked Control Panel>Sounds and saw 2 options on Playback tab. Speakers/Headphones (with green check mark) and Digital output device. Tried all options there, but still can't hear anything through speakers, but can through the headphone.
I fixed the sound. Yesterday, I spent almost 1 hour talking with Dell customer service, Technical Department and *** knows with whom else, and all I got that I have to replace my Motherboard ($299). I couldn't find any info on Dell website about Inspiron 1420 Audio Jack Daughterboard as you showed me, so I decided to see it personally.
Today I disassembled my laptop completely using DELL MANUAL FOR INSPIRON 1420 . After I pulled out Motherboard I could find (YES!!!!) Audio Jack Daughterboard. I started chat with Dell again, and spent one more hour trying to explain them, that Daughterboard for Inspiron exists and I am holding it in my hand.... I showed them your link..... I just wanted to buy Audio Jack daughterboard from them, but they were checking my service tag, asked me if I have waranty, where did I buy this notebook...... So, as a result, I didn't get any help from Dell.
The problem is the headphone jack. When you have this combination of symptoms:
* Speakers don't work and are not muted or deselected
* Headphone jack does work
* Reinstalling audio driver does not help
* Audio test in Dell Diagnostics passes
* On models with 2 headphone jacks, one may be "checked" in the control panel as if in use
The Dell laptops with 92HD audio utilize IDT's Universal Jacks technology, which is somewhat complicated. In addition to the usual mechanical parts, the jack also uses current & impedance-sensing techniques to trigger software configuration and switching (to send the audio signal to the speakers). So there are three areas of potential failure: mechanical, electronic, and software. Sometimes, a little very gentle wiggle of a plug in the jack will get it to resume normal functioning, at least temporarily. There is a sensing pin in the jack (Sense_A pin) that is used to detect the presence of plugs and it can be the cause of failure to trigger the software switching. Failure of the sense pin usually results in the computer behaving like there is always a plug in the jack.
Normally the audio test in Dell Diagnostics would confirm that there is a hardware problem, but the Universal Jacks can cause a false positive result in Diagnostics. That is because Diagnostics operates in DOS, outside of Windows, so a Windows software misconfiguration is irrelevant to the test even though in this case it is caused by hardware. So the audio test can pass in Diagnostics, correctly signaling that software configuration is the immediate cause of the problem, but missing that a hardware problem, the bad jack or sensing pin, is the root cause. In these instances the only reliable diagnostic procedures are to try a new motherboard or to use PC Restore (called Factory Image Restore in Vista) to restore the computer to its original configuration as shipped from the factory. If the speakers still don't work after PC/Factory Image Restore then there is definitely a hardware problem even if it passes the normally infallible Dell Diagnostic audio test.
Yes, Jim. To my great regret, You are absolutely right. I checked Control Panel > Sigma Tel Audio and it shows that middle jack is "check marked" as if something plugged in (with all 3 jacks unplugged physically). I don't want to pay big bucks to fix it, so I think I will just plug external speakers there. I ran already Factory restore two times with no results, so I think this is one of my choices. The second one is to buy it HERE
ux283, so I am still not sure what part do I have to buy. On ebay they have Daughterboard with only 3 jacks and which can be attached to Motherboard. However Dell couldn't explain me if this is correct. Anyway, thanks a lot for your attention and help. I really really appreciate that.
I have DELL Inspiron 1420 and have the exact same problem as posted by Alexmark (thanks Alexmark for your good troubleshooting skill) on 29 Sep 2009 8:15 PM. Your description help me to understand and identify my headphone jack problem. For now my speakers work by little gentle wiggle the jack, I might need to replace the headphone jack if the problem occurs again.

So, I am a Software Developer and I was given a task to extract audio from the meeting by any means possible. Our company provides transcription based services for different platform. And we have to do same thing for Zoom.
@chunsiong.zoom thanks for the reply. What we are looking to do is to build a meeting bot that would be able to record conversations of the meeting without getting any consent from meeting host. Is that possible at all with Meeting SDK?. Should the bot always ask consent from Meeting host before recording?.
However, we observed that that recording raw audio is a controlled feature as described here: -sdks/windows/raw-data/. Can you please guide us how to access this feature? We have a Zoom Pro account. If it is needed, we are happy to have a chat to explain our use case. Thanks.
Amanda, we are grateful for your contributions to the Zoom Developer Forum, @amanda-recallai! Your active participation and willingness to share your expertise and experience have been invaluable. We appreciate the fruitful, constructive, and open discussions you have been a part of, and we thank you for your engagement.
I am using Cubase LE8 on a win7 computer.
I want to try something new. I have a video camera that outputs MP4 files. I want to take the audio from this file, add some processing, add some background tracks (background vocals, other instruments etc) that I will record in the normal fashion, master the whole thing down to stereo and then take the new audio track and shove it into the original MP4 file.
So far my attempts to even import the audio from the video file has not worked.
Can someone give me a start here?
I appreciate any assistance that might be offered. Thank you in advance.
