No sound/audio output

[Lakef]

Now I think I am running Debian stretch/test version. Audio function seems to have made some progress, but still no sound in speakers.

Now done the following:
- I have installed synaptic package manager.
- I changed the "jessie" into "stretch" everywhere found in the repositories in synaptic package manager. Below are the current repositories used. Maybe I do not have to subscribe to sources?
- I ran apt-get update in a terminal window
- I made restart of the system
- I tested some sound by playing music on youtube. This time PulseAudio meter moves, which is a progress from before, but I still do not have any sound output in speaker. See result in image below.

Can I replace "jessie" by "testing" also in file /etc/apt/sources.list"? I replaced jessie by "stretch". Isn't stretch and testing the same thing?

I have run some commands and show the results below.

I checked in the system settings - Software management and there i have linux-image-amd64 and linux-image-3.16.0-4-amd64 installed. Obviously I do not have the stretch version! I think the stretch version has a 4.9 Linux Kernel. Did I do the update from stable to stretch wrong? How I made the update is described in this post http://forums.debian.net/viewtopic.php? ... 15#p637367

Oh, I just realized that I didn't do apt-get upgrade! I did that now!

There is a very good chance that simply using a newer kernel, which has newer sound drivers built into it, would have gotten the sound working. They include "quirks" to fix issues such as you have encountered. That is why I keep urging you to test a Live ISO with a newer kernel to test that--it is a rather simple procedure to upgrade the kernel in Jessie if you find that those Live sessions provide sound. Now you went and did a partial Stretch upgrade without fully researching on how to do it correctly...

Any one of the distros you can find that offer a Live ISO (just about all) have clear explanations on their sites as to what a Live Session is and how to create a bootable Live DVD or USB flash drive from the ISO. I'm not going to repeat their work. I suggested MX 16 64-bit because it uses a Debian 4.7 kernel that was in jessie-backports at the time it was released, closest to what you'll find in jessie-backports now. Ubuntu and its spinoffs use their own kernel with different modifications, so I can't predict how that'll transfer to a Debian system.

If you do try MX 16, again remember I said 64-bit; the 32-bit uses the stock 3.16 Jessie kernel, since we figured users that required a newer kernel, etc., would also have the hardware to run 64-bit. MX 16 should also install from a Live USB session in less than five minutes and does not use the Net during the install, should you care to install. That, plus its "save home" option, has the unfortunate side effect of beginning MX users often just doing a quick reinstall to revert some configuration change they made by mistake instead of just doing the research to find out how to fix the minor problem. So if you have a rather mangled MX system like you probably have done to Debian, you could reinstall in a few minutes.

I did not manage to update to stretch "from within" Debian Jessie. I still had the old kernel (linux-image-3.16.0-4-amd64) and could not manage to update it to the new kernel (linux-image-4.9.0-1-amd64). So instead I prepared an USB memory stick with Debian Stretch version (debian-stretch-DI-rc2-amd64-netinst.iso). But the system never started up properly (on reboot).

My next step was to try Linux Mint 18.1 Cinnamon. The installation process was very easy and smooth. Out of the box, the screen/monitor got proper resolution and Bluetooth functioned. Although, still I have no sound output.
