No, I'm not deaf . . . but audio has suddenly disappeared

Good morning!
I seldom use audio when reading newspapers online - in fact, I usually navigate away from talking heads from last night's TV news reading (badly) at me while I'm trying to read more detailed reports.

But now that all sound has gone - as from yesterday - I suddenly miss it.

The reason for its disappearance: I must've unintentionally pressed something.

I Googled my problem and followed the most commonly given instructions: Control Panel - System - Hardware - Device Manager. But I couldn't fix it. Messages popped up after I reached Device Manager saying "This device is working properly".

The audio system is Realtek. The laptop is a Lenovo Flexi 3 which I bought a few weeks ago . . . and it works perfectly.

I surf the net as well as using Word (for work) and Thunderbird's email client (for work and personally).

I don't really need audio but I like to know it's there. I'm good at what I use - but computer illiterate in respect of the rest. I don't understand instructions that are highly technical. Is there a simple tweak - something I can tick or untick - to get things working again?

Can anyone help sort out this time-wasting problem?

Can you change screen brightness by pressing F11 and F12? If so, press F1 or tap on F3 repeatedly.

If you need a key combo like Fn-F11 and Fn-F12 to change brightness, then use Fn-F1 and Fn-F3 to try to get the sound back.

I blame Bill Gates.

Try "alt"+ "4"

I lost access to my Outlook e-mail the other day, Quote: cannot access default files Outlook.psc. and expecting to lose an arm and a leg at the I.T. repair shop nevertheless I took my laptop in, and the man did just that, i.e. restored my Outlook within 45 secs of walking through the door,( and didn't charge me, having emptied my wallet a few weeks ago over something else ) this after a weekend - these things always happen at 16.59 on a Friday - of Googling, downloading rubbish programmes "guaranteed" to enable one to read Outlook.psc files ( or something like that ) Nothing worked, hence my trip to the shop at 09.01 on Monday.

His rationale being that alt+4 re-starts, i.e re-boots ( I think ) which is not the same as shutting down and re-starting, which I'd done many times over the weekend in a vain attempt.

Don't ask me, but give it a try, nothing lost.

Thanks to both of you (since I'm not sure whose advice did the trick). But the trick has been done . . . and I now have sound again. Panic over! The man at the computer repair shop didn't charge me for pointing out that the F1 to F4 buttons have - on my keyboard, at least - pictures of speakers in order to increase, decrease, mute and unmute. So, it had been working all along . . . but I'd inadvertently muted it. Thanks again!

Of course if computer manufacturers would only supply proper instruction manuals with their products, a lot of these problems would be solved fairly simply.....

But they don't. I've had my Dell vostro 3300 for years and still don't what functions are activated by the F1 and F2 keys.....

See my previous ..... of course I meant key f4, not just plain 4.
