This seems to happen in many different drivers but it happened more often in newer versions such as 530 vs 525.

Step 1.) Upgrade to Debian 11 first
The process to go to Debian 12 is not as smooth as 11, when trying to upgrade from Debian 10. In fact, it doesn't work directly, so you'll first need to follow this guide to update to Debian 11, reboot and come back here if successful.
Step 2.) Update sources.list
Update your /etc/apt/sources.list like this:

In this example we install debian 10 with --variant=minbase which gives us a minimal/tiny install. Don't use variant if you want the full size install.

Sometimes manual intervention on various Linux system's, including Debian, is required to fix things after waking up from sleep.
One persistent issue is the sound system / pulseaudio needing to be reset and not working until you do that after waking up. It's not clear if it's an OS issue itself or the sound driver, but this will fix things.
Where do we put scripts or commands that need to be used upon wakeup automatically?

ID3 2.4 can cause various MP3 players, especially on vehicles or even computers, not to play or at least not to display the ID3 tags.
In many cases though, since ID3 2.4 is much different than version 2.3, it will cause some players, especially in cars like Lexus not to play. Even on the computer, you may notice if you check the properties of the MP3 that it won't open or show any details (eg. frequency, bitrate and ID3 tags).
One symptom of this in a vehicle (eg. Leuxs,........
If your audio is not working and you got this in your syslog:

The issue is generally caused by too many audio inputs, or in other words you have too many applications that are hooked into pulseaudio.

Here is the scenario, you are using QEMU/KVM and are using something like the AC97 sound driver to pass the host audio to the guest via pulseaudio. This is useful because you can transparently pass your mic input from the host which means you can mute your microphone from the host, which prevents the guest from receiving any mic input even if unmuted.
Mute / Unmute Fix
This issue also seems to happen even if you press the mute button on the microphone and then unmute,........
Volume control will often stop working, if your sound server (normally pulseaudio) dies or restarts whether by itself or by you. The reason pulseaudio may need to be restarted is due to some sort of crash or other issue that prevents sound from working (normally restarting or doing a killall pulseaudio fixes things).
However, you will normally find at least in OS's like Ubuntu/Mint 16/18+ that you cannot control the volume whether adjusting the level, changing input/outputs and........
How To Compile QEMU Manually (using sensible options)
1.) Download the QEMU source file you want.
wget https://download.qemu.org/qemu-4.2.0.tar.xz
2.) Extract The Source File
tar -Jxvf qemu-4.2.0.tar.xz
3.) Switch to the extracted source
cd qemu-4.2.0
4.) Make sure we have the right libraries and tools to compile QEMU manually

The problem for me is that Ihad two videos with different types of audio streams. ffmpeg would join them but they would not play past the point of the join.
So Iused mencoder like below and it joined the audio and made them both mp3 streams and it worked!

after the oac the two files are the ones to be joined.

A very common use case is that you don't want to waste time using a video editor that requires you to open it up and manually import the video clip and audio clip, then manually delete the old audio track and import the video and new audio. That's too much work and time since we don't want to go through the hassle.
ffmpeg is our solution, all we have to do is specify 3 variables and we're done!

This assumes your system is a fresh and normally working install.
What often happens is that many new devices have multiple audio outputs which are generally analog and HDMI/Digital out. Sometimes the OS defaults to the wrong one that you didn't want.
For example if your sound is supposed to play over the HDMI, perhaps the output is set to analog or vice versa.........
In QEMU 4 or higher you can no longer use the normal "-soundhw ac97" flag and it is much more complicated but here is a simple copy and paste on Linux that will just work:

I used to believe that for Desktops especially that the "ondemand" CPUfrequency changing that kernels included with Ubuntu and Debian based distros have would be sufficient for snappy performance.
However, you can feel the lack of performance on the fastest computer if you have ondemand. A lot of times even under high load 100% of your CPUfrequency in MHz will not be used.
For example a 2.8Ghz CPUmay only run at 1.8MHz or even .9GHz. Now........

When things go wrong your video is basically unplayable or the first video plays fine and then freezes when moving on to the next. Generally if both videos weren't produced with the exact 100% same settings you will have issues. You can try the basic concat but it often won't work right.

My example uses 3 videos in total so "n=3" and a=1 to include audio.
