[CLOSED] Audio Lost after Software Update

Why have I lost perfectly functioning audio on my Zorin9.0 system after merely applying the latest Software Update?
I believe this last Software Update included a kernel update as well since I had to Re Start my computer afterwards .
How can I regain my previously working Audio functionality?

I'm assuming you have gone into the Sound program in System Settings, and made sure your audio interface is the one selected? Beyond that, you're going to need more help - I'm not much more than a noobie. (But I'm trying to help out where I can).

Correct assumption.
Analog Audio (as opposed to Digital Audio) *is* selected as before. Now NO audio, or buzzing sound when it is "tested".
Audio worked with NO problem prior to Software Update.

When you see the GRUB boot menu - choose the 2nd Option from the menu and choose the earlier kernel to boot into - if this is the issue, will guide at some point how to remove the kernel release.

Thanks Swarfendor

I used Grub to select the previous kernel (3.13.0-68) as you suggested, instead of the *new* current kernel (3.13.0-71) and audio was GOOD in this previous kernel!!
Strangely, after Re Starting and booting yet again into the *new* default kernel (3.13.0-71) the audio is *NOW* Working!!
I have NO idea why this is so? A Bug of some sort I guess?

No idea on that my friend - please remember that kernel releases will affect all variants of GNU/Linux, not just Zorin!

I will 'close' this thread.
