You must be kidding. Where did you find out that D610 does not have internal microphone?
I just upgraded from D600, which had internal mic. Darn! And my D610 mic. does not work, darn again!
I have just installed updated driver from Dell - R99254.EXE with not success.
Now when I jiggle expernal mic. a little and keep it at certain position it seems to work (but not a permanent solution). Can't be happening ... a brand new laptop!!
Yes, you can read complaints about the D610 not having a mic all over the net.
But you say, you got an external one to work ? Did you connect it via USB or the normal plug on the left side on the machine ?
Still the question remains for me how to get my headset mic to work ....
I had exactly the same problem as Jochen K. I called DELL Support and they walk me through the web page to get a new sound driver and It worked!!!. Now I can use MSN, Skype, everything.
Go to: support.dell.com -> Consumer (Home &Home Office) -> Product Support (drivers & downloads) -> Select your model Latitud D610 and search -> Select your OS and click on find downloads -> select Audii Driviers, you will find just one. So download it and when it finished run it and it will install the new driver. I restarted my computer despite it didn't ask though and then it worked!!!.
I hope you can get your Mic to work. good luck.
I am using simple KOSS headset and microphone. But it does not matter. Just make sure it has stereo jacks of course (for both).
I was able to get mine to finally work. Thought you guys might want to know what I did (and anyone else in the future), if you guys still weren't able to get an external mic going.
First, I went to the support.dell.com website, entered my service tag, clicked to get into "All" drivers, clicked the Audio one (there's only one there for a Lat D610), and I downloaded & installed it. Direct link: www.dell.com/.../latitude-d610
That downloaded R99254. It didn't work.
So I did some googling. Found this one on Softpedia.com:
That downloaded R90052. It didn't work.
The reason I'm including these links is because I'm not sure if it was the combination of having those drivers with what I did next did it, or if what I did worked on its own, but...
I was in the middle of running the Hardware Test for my mic to see if the last driver download worked. It got past the pre-check to where you do the speaking part, it didn't work to show any colors on the mic to represent audio. Well I took the mic plug out, put it in halfway like it's been saying on some posts. No dice. I played with it a bit, put it in a bit more (about 3/4, I guess), while I was doing voice tests - finally it started registering my voice. I inserted it fully and it still kept registering my voice! I think there's some kind of activation that has to happen by putting the mic plug halfway (or 3/4) into the jack, and then fully after it has enough time to realize that "hey, there's a mic here!". Stupid Dell...
Hope this helps someone...
