There is something really weird going on [at least beyond my understanding]. Earlier I tested skype and it worked [audio] after I had adjusted the volume of the input device. The first line in the Input Devices window stated: "HD Webcam C615 Analog Mono". the "mono" is the key from past experience. I adjusted the volume. Port: Microphone

The bottom half of the Input Devices window had: Built-in Analog Stereo Port: Front Microphone (unplugged). with these readings audio worked.

When I went to test skype again before replying to you the audio did not work. The Input Devices window had also changed: the readings had reversed: The first line showed: Built-in Analog Stereo Port: Front Microphone (unplugged) and the bottom half showed: "HD Webcam C615 Analog Mono" "Port: Microphone" Why is it unstable?

On skype under audio video settings: the microphone is selected for default device "automatically adjust microphone settings" and for Camera "no device fpund".

What I would recommend is that you update your kernel to the latest supported for your distro (which is, I believe, 4.13.0-26) and then test it again. It could well be that your webcam hardware problem is resolved with a more recent kernel.

The Configuration Window has also reversed the order.
Top line used to state: HD Webcam C615 Profile Analog Mono input' it now states "Built-In Audio" "Profile Analog Stereo duplex"
Bottom half used to state Built-in Audio Profile Analog Stereo Duplex" it now states HD Webcam C615 Profile Analog Mono input"

Why this reversal? I think I need the top line to state "mono".

I am on automatic software update. Would it not automatically update the kernel? It looks complicated {I was searching the web] and I am afraid to screw up my system.

Hi Hydrurga,
I finally got audio again. I restarted and in PulseAudio the first line for Input Devices returned to "HD Webcam C15 Analog Mono." I made any necessary adjustments to reflect the images I had taken earlier of the different windows in Pulseaudio and the audio returned.

What I don't understand is why the first line displayed "Built-In Audio" "Profile Analog Stereo duplex", which is the incorrect display [no audio when it appears as the first line]. Right now I have Firefox and Thunderbird on and they have not affected my Input Devices Window.

Later I will listen to something on You Tube and see if it affects skype by changing the first line. The other worry is that while I am speaking to Italy the first line changes [from HD Webcam C615 Analog Mono] to Built-in Analog Stereo. It's the stereo that does me in. It will mean re-starting my computer.

I don't run Ubuntu so I'm not sure how you update kernels with that distro (it's easily done on my distro, Mint, through the Update Manager). A quick Google turns up this page: https://www.tecmint.com/upgrade-kernel-in-ubuntu/

I recommend upgrading only because I feel that perhaps you are experiencing problems due to lack of kernel support for your webcam which may have been resolved in a more up-to-date kernel.

If you are worried about breaking your system, perhaps you could create a new thread here asking for someone to walk you through a kernel update, emphasizing that you want to keep your current kernel as well so that you can roll back to that kernel if anything goes awry with the new one (this should be easily done through the startup Grub menu).

Hi Hydrurga,
I am going to take the easy way out. I'll switch to Mint [on my drive] and see if I can easily update the kernel for it. I also want to check with a friend who works with Linux to see if his video works. I bought my video cam because he has one and it worked on my system. I think it is a question of being behind in the updates but I'll find out.
With Xubuntu I will just wait.

Thank you for your patience and help.

Hi Hydrurga,
My friend sent me the following link:
https://answers.microsoft.com/en-us/...d842084?auth=1

So it seems Microsoft is responsible for the problem.
Right now I am using Mint. I installed cheese and my video cam works but is a little slow. With Xubuntu it moves in real time.
I tried audio on skype and it worked, but who knows for how long. I think the problem is that I have to bind the channels so they function in mono. It is easier to see in Pulseaudio in Mint than in Xubuntu but I will try tomorrow.

Hi Hydrurga,
Just want to update you. I now can get audio in both Mint and Xubuntu. The error was mine. When Skype updated it defaulted the values, and I should have started from scratch and remove the use automatic from skype and then separated the two levels with Pulseaudio. Now if only someone will update the driver for the video...

Hi hydruga,
I have "solved" the problem --downgraded skype to version 8.11.0.4. At least I downgraded on Xubuntu, but when I tried to do the same on Mint I can't enter my password. I also think I may have solved the problem as to why when conversing with Italy the system hangs. I had both Wi-Fi and Ethernet on "enable", and I think they are splitting the bandwidth. Well, I may be totally wrong but I will soon find out.

Thanks for the update, RenH. It's a pity that you had to downgrade but at least you have it working. That's the key thing.

It may be a regression introduced by the updated version of Skype that will be corrected in a future release, so do consider upgrading past the non-working version in the future to see if that works and attempt to get your version back on track.

For Mint, I would recommend purging Skype altogether and reinstalling the older version to see if that solves the password problem.

I have to say that generally the conversations I have with Skype are pretty unsatisfactory, with conversations breaking up and the call sometimes being lost. Cutting video often alleviates the problem. I used Whatsapp for a call for the first time recently and, apart from an echo on the phone, it went pretty smoothly. Messenger for Desktop is also an alternative. I would suggest that you and your colleague try some of the alternatives (one of the categories for this year's LQ awards is VoIP so refer to that) and see what works for you.

thanks hydrurga, I was looking at alternatives to skype, so your recommendations came at the right time!

I managed to downgrade skype on Mint. The fault was mine, as I had forgotten that Linux does not show anything when one enters one's password. Armed with this knowledge I was more patient and all went well.

Problem with skype updates via the automatic updater is that I can't tell what is in the update.

Do let us know if you find a reliable alternative.

You can place a "hold" on Skype to stop it being updated:

Code:
sudo apt-mark hold skypeforlinux
You can release the hold with:

Code:
sudo apt-mark unhold skypeforlinux
and show your currently held packages with:

Code:
sudo apt-mark showhold
If your system supports it, you can replace all the sudo apt-mark above with a simple apt.

Thank you, hydrurga! I will indeed let you know if I find a good alternative. The problem, of course, is convincing my friends to change to the alternative.

It does indeed take two to tango.
