AI Thread Summary
YouTube videos are playing in fast forward on Ubuntu running in VirtualBox, with users experiencing similar issues on Linux Mint. Suggested solutions include changing audio output settings and installing the adobe-flashplugin package, but users report difficulties with both. Errors related to repository configurations and package installations are common, indicating potential issues with outdated sources or missing packages. Some users have found that disabling audio output allows videos to play normally, suggesting an audio-related problem. Ultimately, reinstalling VirtualBox and upgrading to the latest versions of Ubuntu may resolve these issues.

Hello,

Everything was just fine, and today when I opened Ubuntu on VirtualBox, the videos on YouTube played fastforward (and the voice as well). I googled this issue, and the solution seemed to change the audio output option as System>Preferences>Sound>Output Then select "Internal Audio Analog Stereo Stereo", but I don't have this option. What else can I do to solve this issue? I also have Linux Mint, and it suffers from the same problem. It does seem that turning off the output audio makes the videos play in normal speed, but there will be no voice!

Thanks

This video walks you through some steps. It may be what you tried already but may be not.

It is, actually.

I don't know the Ubuntu version you're running but regardless if you go to "Sound" tab , "All Settings", (sub)tab "Output", "Play sound through" there is the option "Analogue Output". Did you try this?

Yes, I did. Didn't work. I use Ubuntu 16.10, but I yesterday installed a new version 16.04.3 LTS, with the same problem! It seems to happen on all Linux OSs on my computer. I checked the Flash Player, and it is deactivated and marked as vulnerable software or something, and I cannot activate or install it. I am not sure if this has anything to do with my problem! I also tried different commands as it worked with some users, like

Code: 
pulseaudio -k
killall pulseaudio

but didn't work for me.

Did you try to install the adobe-flushplugin package? This is for both Firefox and Chromium like web browsers. In order to get it make sure that the Canonical partner repository is activated (there have been issues with errors related to old repositories so that's why I 'm pointing this out). Then run

Code: 
sudo apt-get install adobe-flashplugin
.

Yes, the Canonical Partners is checked. I tried to run this command before, it gives me the following error:

Code: 
E: Unable to locate package adobe-flashplugin

Do you have "canonical" in your "/etc/apt/sources.list"? Check and if not add the line

Code: 
deb http://archive.canonical.com/ubuntu yakkety partner
Then run
Code: 
sudo apt update

If you already have it then I would recommend to install all the multimedia plugins and libraries needed for .mp3 and video formats by running

Code: 
sudo apt-get install ubuntu-restricted-extras

This will also install adobe flash player.

How can I check "/etc/apt/sources.list"? I put this in the terminal and it gave me "Permission denied". Then I went to Software & Updates window, I checked the "other software" tap, there was canonical partner, and when I added

Code: 
deb http://archive.canonical.com/ubuntu yakkety partner

it added (Source Code) at the end. So, I have duplicates now. Shall I remove one?

Anyway, after that I tried to update using

Code: 
sudo apt update

and I got a bunch of errors saying that

Code: 
X: The repository Y does not have a Release file

with different Xs and Ys! What does this mean?

You can open the "sources.list" file using some editor e.g. nano. Run

Code: 
sudo nano /etc/apt/sources.list

Take note that before making any modification to your "sources.list" file you have to create a back up in order to be on the safe side. You can do this by running

Code: 
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

Alternately, if you try to add a line to the file from a terminal and get "Permission denied" you can run
Code: 
sudo su -c "echo 'deb http://archive.canonical.com/ubuntu yakkety partner' >> /etc/apt/sources.list"

I have to point out that the method of using "su" is dangerous regarding grant of privileges so it is not to be used if there is no absolute need.

One is enough.

It has no files for your version.

I checked the canonical and it was in the sources.list. Running the command

Code: 
sudo apt-get install ubuntu-restricted-extras

gives me the following message:

Code: 
W: Target Sources (main/source/Sources) is configured multiple times in /etc/apt/sources.list: 2 and /etc/apt/sources.list: 7
E: Unable to locate package ubuntu-restricted-extras

There seems a duplicates in the lines specified above (2 and 7 in the sources.list). These lines read as (counted from the first line)

Code: 
 Line2: deb-src http://archive.ubuntu.com/ubuntu yakkety main retricted

 Line7: deb http://archive.ubuntu.com/ubuntu yakkety main retricted

Did you add the line I mentioned in the "sources.list" file or there was already a duplicate in there? Also, I see that you've edited your last post - it was previously what I've quoted above. I say it because I see two typos there i.e. in
Code: 
Line2: deb-src http://archive.ubuntu.com/ubuntu yakkety main retricted

Line7: deb http://archive.ubuntu.com/ubuntu yakkety main retricted

the word "retrictred" instead of "restricted".

Is it like that in your file or it was just a typo in the post?

I didn't add anything to the sources.list. After I found the canonical line, I exited the file.

My mistake, both are "restricted". Yes, they were typos in the post. I was typing the line manually. I edited my post, because I found out that the second line, namely

Code: 
Line7: deb http://archive.ubuntu.com/ubuntu yakkety main restricted

is in fact line 6 not 7 in sources.list. Line 7 (again counting from the first line with a #, and the count includes empty lines) is

Code: 
deb-src http://archive.ubuntu.com/ubuntu yakkety universe multiverse main

I have these lines

Code: 
deb-src http://archive.ubuntu.com/ubuntu yakkety main restricted

deb http://archive.ubuntu.com/ubuntu yakkety main restricted

Are they duplicates because of -src in the first line?

S_David said:

They are not. The deb-src repos contain the source code files for the software which is in binary form in the deb repos.

I don't see any identical lines. Now what can I do?

You can go to Ubuntu Software Center > edit > software sources and see in the "Ubuntu Software" tab if (main), (universe), (restricted), (multiverse) boxes are checked (if not check them) and in the "Other Software" tab do the same for Canonical Partners and Independent. Then run

Code: 
sudo apt-get update && sudo apt-get install ubuntu-restricted-extras
and check if it solved the problem of getting the ubuntu-restricted-extras.

In Ubuntu Software tab all are checked, even the Source Code (shall I remove this?). In Other Software tab the Canonical Partners is checked, but I don't have Independent!

The source code is useful if you want to download it and compile it yourself so it's up to you if you need it or not.

Never mind I talk based on one of my distros so no problem for Independent.

It did some updates, but at the end it displayed messages like:

The repository ... doesn't have a Release file.
Failed to fetch .../sources/Sources 404 Not Found
Data from such respiratory cannot be authenticated ..

and the problem is still there!

The point is if it installed flash plugin. You must manage to install it in order to see if it solves anything - I have already seen quite a few video playing issues related to Flash but I obviously can't tell for sure that this is the problem in your case. If not then the most probable culprit is video drivers. As for the messages after the update process I think that they're pretty much self explanatory so you can easily cope with them.

I installed and ran

Code: 
pavucontrol

and when I went to the Configuration tab and put the output to off, the videos played normally, but with no voice. Doesn't this indicate an audio problem?

Regrading Flash Player, how can I know I installed it? As I said before, when I tried

Code: 
sudo apt-get install adobe-flashplugin

it gave me that the package cannot be located.

The error messages I mentioned weren't happening before. Why are they happening now? and the question is: are they related to the problem at hand? I remember that this version 16.10 was supported for a limited time, but I am not sure if this is the reason, but I have another version and another distribution, and all suffer from the same problem!

The problem is fixed by unistalling VB and all the OSs in it, and installing the last versions of VB and Ubuntu (17.10).
