I recorded a video/audio on an iPad and sent it to my iphone via Message. I click on the video and it plays but no audio (audio is present on the ipad). I save the video to the iphone and now when I play it the audio is there. No biggie, I'm thinking. So, I download the videos from icloud and load them into the laptop running Linux Mint 22. Start up a project in Shotcut but again there is no audio on any of the clips. I try them in Kdenlive...same thing. Most of the time this issue doesn't happen and all is well.
This has happened before with videos/audio shot with iphone also. This laptop use to have Windows and the same issue happened. Now its happened on Linux Mint.
I use to think the fault was the Dell laptop itself but it also happened on the HP Notebook. Its maddening.
Any ideas to try?

Dell Inspiron 3558
2.1 Ghz
 


if the issue is not OS dependent (ie: it happens in both windows and linux) then I'd think it's a hardware issue, but if it's happening on multiple devices then it's got to be a problem with the media itself - how it was recorded/encoded/etc
 
iPad uses ALAC I believe - (Apple Lossless Audio Codec) for their audio so that is why it does not have any sound in Linux - you need to get a codec that can play ALAC -I think ffmpeg will play it - you can get through the Synaptic Package Manager just type it in the search box - install reboot check audio - a lot of Linux distros do not include ffmpeg by default you have to manually install it - I have this installed on my Expirion Linux by default
 
@GatorsFan :-

Yup; I would tend to agree with you there.

Apple employ a whole bunch of proprietary stuff, mainly to "lock" their users into their hardware/software "walled garden". We ARE fortunate, however, in that many smaller projects DO exist in the Linux realm to help cater for this stubborn approach to multimedia support.......and of these, ffmpeg is certainly one of the most versatile AND easiest to obtain.

In Puppy, we've been using the statically-compiled builds by John van Sickle for a long time. Yes, they are quite large, compared to the repository versions, but then absolutely everything else normally installed via the package management system in the way of dependencies is already "built-in".

All the user needs to do is to download the version they want, unzip the tarball, then move the resulting 'static' binary into /usr/bin. It's THAT simple, and.....hey presto! support for every proprietary codec you can imagine is then available.

It's a good solution, and these builds are auto-updated on a "nightly" basis.....so are always as "current" as possible.

~~~~~~~~~~~~~~~~~~~​

It fixed a lot of issues with my Puppies when we found these static builds, since OOTB, Puppy always used to employ a very basic, stripped-back, 'bare-bones' version of ffmpeg. I could never understand why it was that mainstream distros seemed to cope with varied multimedia absolutely fine, whereas Puppy always seemed to struggle with the same items.....and this was on the exact same hardware. It wasn't the fault of the hardware; as it turned out, the expected - and necessary - software support simply wasn't there to begin with.

Puppy tended to use a build of ffmpeg that catered to the default, minimalist multimedia apps that came as part of the ISO, OOTB. This was fine if you never wanted anything beyond basic MP3/MP4 support.....but as you know yourself, things are never that clear-cut. Codecs evolve over time, and different types wax & wane in popularity. Years ago, Puppy was, to a large extent, a victim of its own design philosophy.....that of keeping everything as small and lightweight as it could, to ensure stuff worked on the elderly hardware it traditionally targeted.

A decade on, and many of us are now running far more capable & powerful hardware than we ever used to. It only makes sense that the available software evolves to match the better hardware abilities....

(shrug...)

@phreddy53 :-

Much of this centres around individual distro design choices. A popular, mainstream distro like Ubuntu - which Mint is based on - will very often contain pretty much everything including the kitchen sink. Many other, more lightweight distros will come with very much reduced multimedia support, leaving to the individual to add necessary software if, as & when required/needed.

The fact that a lot of proprietary software, including codecs, often needs licensing agreement means that frequently, certain items aren't supplied as part of the respective ISO downloads. It's all part & parcel of the open-source nature of the Linux experience.

After installing ffmpeg seems to have fixed the problem on Mint. However, ffmpeg was also on Windows but the problem was still present.
Odd thing about this problem is sometimes I can close out a project and reopen it and the audio will play.
The only common denominator I see is Apple.

In Windows try either iTunes or Apple Music App see here https://support.apple.com/guide/music-windows/play-lossless-audio-mus90b573cbb/windows or VLC - glad Linux Mint is fixed - yep Apple proprietary codecs can be a pain
