Hello. I have a new T450s with Windows 10.   I hit F4 and the amber light goes on showing the microphone is muted.  Problem is that it "looks" muted but it is not.  I have also gone in through the software to mute and it lights up the F4 buttton.. However, it doesn't actually mute the microphone.   So I can never mute the mic..  Is there a fix for this? I see others have had this problem in the past.Thank you.

A:Cannot mute microphone with new lenovo T450s

Same problem with an old E330. The problems started when upgrading to Windows 10 + Realtek HD Audio Drivers (or the Lenovo Realtek Audio drivers, just rebranded). Something in that combination breaks the microphone's ability to be muted by software. The button works ok, the On Screen Display shows the icon and it's shown as muted however still works.Muting it manually from within programs which use the microphone works as well, as does uninstalling the Realtek drivers and going forth with the default Windows 10 drivers (but then there's a loss of functionality with the sound - options).

I'm running windows XP on an old Dell Inspiron 1501 and I'm trying to get my microphone to play directly through my speakers so I can record them both simultaneously. The only answer I've been finding is to tick the 'microphone' checkbox in the volume control playback properties panel, but I don't have a microphone checkbox.There should be a 'microphone' box under SW Synth and CD player but I don't get one apparently.I've downloaded the latest SigmaTel Audio drivers from Dell and despite not having a problem with them before this, I'm inclined to believe that they're the problem. Any ideas?

A:No microphone control in playback Volume Control panel

Okay well of course I find an answer right after posting the topic:
http://en.community.dell.com/support-forums/laptop/f/3517/t/19295458.aspx
http://en.community.dell.com/support-forums/laptop/f/3517/p/18112824/18235810.aspx#18235810

Those two pages detail how to get an Input Monitor checkbox which functions just like the microphone one I wanted (although you can only mute it, not alter the volume). I used Instructional Set 3 from the second page, having to add the 'RecMonitorMute' entry as detailed in the first page and I can now hear my microphone input directly through my speakers.

HOWEVER, I'm still unable to record both the microphone and speaker sound at the same time. I thought recording the 'Stereo Mix' channel with the microphone coming through the speakers would work but it isn't and I don't know why. Any ideas?

I keep getting this error after right-clicking the microphone's control panel taskbar icon. I still can open the panel and change the settings, but this error is stressing me out. I just switched to a completely new PC and I'm afraid that this might be caused by some hardware malfunction. It never happened before on the old machine. I even did full system re-installation but I keep getting this error.

Did you first install the software for the mic before connecting it? If you connected it first there could be incorrect drivers installed by Windows.

Hello,

I just got the Dictation 11.0 voice to text software in the mail, and after installing it and using the headset microphone (everything working perfectly), I pulled the microphone cord out of the jack while the software was loaded (why i do not know why i did that) and when I put it back in it does not work.

A bit of background info:

I run windows vista on a laptop and when I tried to trouble shoot it, my bright idea was to go into control panel and disable the mic, and the try to enable it again. Now I cannot find my microhpone anywhere in the control panel to re-enable it. The software still picks up that the microphone is connected (although the control panel does not), but neither can register any sound.

I did check to see if anything was muted in the mixer, and nothing is.

Does anyone have any ideas?

forever grateful for any input.

thanks

Hello, all.My T420 audio system has worked perfectly for years. But, starting in January 2018 the microphone mutes itself, no matter what I do with its settings. Sometimes the muting happens in a few seconds, sometimes after a few minutes. I can watch it happen in the microphone levels window. I suspect a Windows update or new version of Skype caused the problem. I have been unable to fic it. Neither Malwarebytes nor any Windows security scanning software see any issues. This is especially aggravating since I'm a software engineer used to fixing bugs. (Yes, I've watched the YouTube videos about this problem, to no avail.) Anybody have a fix for this?Cheers,Dave

I'm thinking about buying a Blue Snowball iCE because they are fairly cheap and but have great sound quality. I've read some reviews and watched some videos and I'm very happy with this mic, the only problem is that is doesn't have a mute button. I use the mute button a lot because my parents come in to my room frequently and just start talking, so i need to mute my mic so my friends can't hear them. The Blue Snowball iCE mic doesn't have mute button on it so i need a quick way of muting my mic.

I thought of putting in a switch in the wire that goes into the PC. The mic is connected to the computer by a USB, is there an extension wire i could buy with a switch attached to it, that i could plug the mic into and then plug that into the computer?

I really need a fast way to mute my mic and if anybody has any ideas I'm open to them!

The sound quality is fine, but the microphone is constantly on and can be heard in the speakers or headphones while I have it turned off in the programs. I have tried front and back USB ports and three different programs and it is always the same. I have an older laptop using Windows 7 and the microphone works perfectly with full control.

Any suggestions would be most appreciated.

Hey,
Every time I restart my computer I have to re-mute my microphone in the levels tab in the sound option. I do this so I do not hear myself talking through my speakers from my microphone, but so I can still use the microphone for applications.

Also, the microphone boost turn's off every restart as well.
So pretty much, every time I restart I have to mute my microphone again and re-enable the microphone boost.

What I want is too not have to do this on every restart. It only takes me about five seconds to set everything back up so it's only slightly annoying.

I have a creative x-fi xtreme gamer fatality sound card. I have set the correct settings through the audio console as well, but it still reset's to the microphone being set on and sound boost off on restart.

Thanks for any help.

Since you have to hunt around different Lenovo sites (and other sites) to find out about these softwares, I decided to make a post to get feedback from actual Yoga owners on how these programs interact, what they do, which ones are prerequisite, and which ones are unnecessary. Please don't take this as a blanket answer. This is just what I have found. It might be right - it might be wrong. I'm looking for others to post their experiences as well. Lenovo System Interface Foundation Driver - Necessary prerequisite (missing driver in device manager without it). It allows the Lenovo Utility and Lenovo Companion to work. Lenovo Yoga Mode Control - Necessary if you want to use your yoga to seemlessly change between all the different modes (laptop, tablet, tent, stand). This software is responsible for autorotating and putting Windows into tablet mode. Lenovo Utility - Recommended(?) This one I'm not too sure on. I remember that I was missing some function that I wanted but I can't remember what it was now. Maybe battery cycle count and health? Lenovo Companion - I don't have this one installed and don't think it's necessary but would like someone else to shed some light here.

Hi Folks,I recently bought a refurbished Lenovo T420 which is a very nice piece of Kit, I am Hard of hearing and mostly use headphones for audio. However, this T420 seems to have something else other than the 3.5mm combo socket in place, on the right corner panel, just before the CD tray. The company I bought it from indicated that it should not be there and they suggested I try to  "Pry it out with a needle"?.Obviously I'm not going to do that untill I know what this is and why its there? I cannot connect normal head phones because there is no 3.5mm socket. Can anyone identify what this is please?3.5mm socket should be here

I am curious as to why the volume control is muted on boot. The system sound is set to "No sound". The tech info about my desktop is in my signature.

A:Volume control set to mute on startup

If you have your sound set to no sound then of course their will be no sound at boot.
At least that is my understanding.

Dear all,

I went through the different steps mentioned in "clean-up-factory-bloatware" article, apart from last point which consists of re-installing my machine! But still I have BSOD and it drives me crazy.

I attached the DM Log Collector results. Hope you'll be able to find what causes this.


Thanks for your help

You could try an older driver version.

My laptop LCD has been out for awhile and I've been using with an external monitor, but I decided to fix the LCD so I ordered a new LCD screen for it. The lcd screen arrives, install it and picture still doesn't show up. I then thought maybe I just had a bad cable from motherboard to LCD so I replaced that.. still no luck.

I can see a faint image in the background, but it's very dark. Same with my original screen.

What's odd is before my original laptop would show a just scrambled picture of black and white-- which is why I originally thought it was LCD.

What would the next step be? To order a inverter? Do the symptoms above sound like it's a bad inverter?
