Windows 7: mic not working on front panel

mic not working on front panel


I bought my wife a new pc as the old one was a single processor and very slow. It has 2 issues. The new one seemed straight forward, quad core much faster but two issues are annoying enough to make my wife not want it.

1. The front panel seems to be wired differently to the old pc - my wife uses headphones with a mic for skype. Plugging in the phones did not get any sound. When I fixed this (I ticked the disable jack detection box which makes the phones part work but the mic does not work) the muting of the rear did not work. I swapped the old front panel from the old pc which includes a firewire port - so I am guessing the cables to the motherboard are digital rather than analogue? - and with this auto detection works. So is this an analogue vs digital issue? Trouble is the old panel won't fit the new case so I am stuck with the new front panel. As I say I can get the phones to work, the mic generally not but it did seem to work one time my wife played with setting (I was absent) and the auto mute does not work. I read some threads about ac'97 but nothing seems definitive.

2. I added in the hard disks from the old pc. One of them is recognised but after a while disappears. Explorer just does not show it and you have to reboot. The other is ok all the time.

Any help appreciated - I am semi techy by the way but not very. I can get the processor/motherboard spec if needed - it's Gigabyte I believe. Running Windows 7 64 bit.

hi there
to help diagnose the pc could you download a program and show the results partially the sound/Graphics etc that will show the details its very safe and secure used by many members on this forum its called speccy by piriform. link is here Speccy - Standard

What's in your computer? If you're like most of us, you can probably name the processor (Intel or AMD, Celeron or Pentium), maybe how much RAM it has, and maybe how big the hard drive is.
When you go to a computer store and see all the bright shiny PCs laid out next to each other, most will have tags or stickers indicating the:
Processor brand and model
Hard drive size and speed
Amount of memory (RAM)
Graphics card
Operating system
Two or three years later, when it comes time to upgrade your computer, that tag or sticker may be long gone. Speccy was designed as a free electronic "what's inside" sticker for your PC.

Thanks for the suggestion - I have realised that this may be related to a Skype specific issue - the mic is ok, it's the phones part of the headset which does not work, yet when playing music it does. Hence I think it's Skype, which shows two Realtek options for phones, I assume one is the front panel.

As for the hard disk I looked at the event viewer and it showed a paging error - not sure what could cause this? Overheating?

paging error can you post the details of this has windows gave you any pop ups like Limited Virtual Memory
Your system has no paging file, or the paging file is too small.

To fix this problem, go to System in Control Panel, click the Advanced tab, and under Performance, click Settings. On the Advanced tab, click Change. Click 'Custom size,' and then type an initial or maximum paging file size.

Paging is an important part of virtual memory implementation in most contemporary general-purpose operating systems, allowing them to use disk storage for data that does not fit into physical random-access memory (RAM).
