Windows 10: How to solve Code 45 - laptop speaker disconnecting from laptop after update, earphones...

This happened a Couple weeks ago, 2nd latest update that I have done with this laptop. I have tried downloading apps to fix the issue but to no avail. I've tried clicking everywhere on Device manager but have only received 'Code 45'.

:)

 

my earphones are working but speakers of laptop are not working??

MY laptop speakers are not working. but when i connect earphones it is working

 

Can't switch between earphones and laptop speaker.

Hello;

Previously I created a question,please see this thread to understand the question :- Redirecting

. The problem is not solved yet and my thread is locked. So I have an additional thing to tell everyone.

I can switch between my bluetooth headset and my laptop speaker and have an option to switch between them but I can't switch between my earphones plugged in the headphone jack and the laptop speaker and do not have the option to do it.







To switch between my earphone and my laptop speaker I have to unplug my earphones from the headphone jack. Any solution to this ? Thankyou.

 

No sound from laptop when speakers are disconnected

I have an elderly (7 years old) Dell Inspiron 17 R that I keep as a fallback laptop. I have Win 10 Pro, fully up-to date.

I recently lost sound, when no external speakers are connected. (For info related to speakers, see further down this post.)

The following are my troubleshooting steps.

------------------------------

Windows Audio is running.

External speakers are disconnected.

In Device Manager > Sound

Disable, then re-enable:

- IDT High Definition Audio
- Intel Display Audio

That did not resolve the issue.
------------------------------------
Download and run: Intel Driver and Support Assistant.

Message: Your Intel Drivers and software are up to date.
-------------------------------------

Control Panel > Sound > Playback tab

Select "Speakers/Headphones"

Click Configure

Click Test

Both speakers pass

-----------------------------------------

Sound is OK from both speakers when they are connected. But on this specific laptop, I really have no interest in any sound coming from the external speakers (or headphones). I simply want the sound from the laptop itself.

How can I restore my sound?

Footnote: I have no Realtek driver. Is that unusual? I can't remember whether the old laptop actually had a Realtek.

Thanks.
