It's my favourite tool for the os side of being able to return to an earlier file version - I use backintime for user/home folder. My guess is that you'll be focussing on the audio side before worrying too much about putting data on the machine.
With Systemback you have to manually back up the folder /program-files as it is a non-standard folder which is not recognised by systemback. Other than that it is the ideal tool (IMHO).

See if that helps, it depends on whether it locks the default in place or whether some progs start looking for a different card.
There is a more complex solution in this debian bug https://bugs.debian.org/cgi-bin/bugrepo … =614113#40

Not sure if this helps to find the issue? Please let me know...
]]>After all that please try the apps that you expect to deliver audio and let us know what happens.
]]>Perhaps a better solution would be to try to understand what is going in now. The linux sound system has always been a weakness with various technologies over the years.
So, first off, please install inxi - sudo apt-get install inxi
Then do inxi -F
Copy and paste results back here so we can learn more about your machine.You say that operation is erratic. Can you identify if this is particular applications, what circumstances can cause it to fail?
After installing software it stops, then I try some troubleshooting and it works for a time but after a system update if fails again
What sound/audio applications have you installed?
pulseaudio and alsamixer
Have you added repos to the standard set - you haven't added Ubuntu PPA'a have you?
I have not
Have you added debian Multimedia repo by any chance?
I have not

... sometimes it works and sometimes just stops doing it.
Please first check cables and try to exclude a hardware issue. Next, follow bin's advice #2 above, thanks bin. You should also check these recommendations https://www.q4os.org/dqa011.html#install.3
Is there any way to completely remove drivers, app files and config files related with the sound subsystem so that I can reinstall it as they were the first time?
No, it's not actually possible, there could always remain a forgotten configuration. The only definite way is a fresh installation.

I've been fighting for a long time with my sound card, sometimes it works and sometimes just stops doing it. Is there any way to completely remove drivers, app files and config files related with the sound subsystem so that I can reinstall it as they were the first time?
Thanks!
