T440 - Sound does not switch between internal speakers and headphones or back

Hi community,

let me first explain how I assume the switch between headphones and speakers should work:
I turn on music or anything esle and if no headphones are plugged in, every sound comes from the internal speakers. Now if I plug in headphones then the sound comes exclusively from the headphones. If I pull then out again the sound comes from the speakers and so on.

 

In my case the situation is the following:
If I have no headphones plugged in and turn on music, then I hear if via speakers. If I decide to continue listening to that music via headphones and plug them in, then the music continues to come from the speakers, but for example the notification sound from outlook comes from the headphones. This works vice versa.
If I open, say youtube to watch a video, while having the headphones plugged in, I will hear the sound via them. If I now unplugg them, the speakers will stay silent.

What can I do that if there are no external speakers plugged in (headphones etc.) every sound will be played by the internal speakers, if I plug in some sort of external speaker it comes from them and if I unplugg it it switches back to the internal speakers?

Thank you very much for your help!

Best regards

Guru

Thank you for your answer.

The drivers were already up to date.

Look in the Realtek audio control panel. There should be a multi-stream option, make sure this is set to unify all devices.

That worked. I was sure I turned that off. Is there something that could trigger it to switch back to multi channel?

Where/how do I find the Realtek audio control panel? All I can find is Realtek HD Audio Manager in my control panel. Thanks.

I know this is a really late response, but I think that's what they were referring to, 'Realtek HD Audio Manager' in the control panel. I saw the multi-stream option in there. It appears when you click the link on the right panel, 'Device Advanced Settings'.

Re: T440 - Sound does not switch between internal speakers and headphones or back

Hello, since this thread is the top Google result for the headphone jack problem I wanted to add another solution in hopes it will help someone.

 

I was eventually able to fix this on my T440 by putting the laptop to sleep (with the phones in, not sure if this mattered) and then waking it again. This is similar to the issue with the dimming functions that sometimes stop working when you sleep (although you only have to open and close the laptop to fix that one).


Note I had rebooted several times in the course of re-installing drivers, which did not help at all.   I also had no options in multichannel.  Finally in desperation I tried sleeping, and then heard the 'wake" sound after logging in.

 

I suspect this issue was caused by some combination of sleep, docking, and headphones being plugged in.

The Realtek manager settings didn't work for me but putting the laptop to sleep and waking it back up did. Weird. But at least I know what to do about it the next time.
