Hi,
I have read the other postings about the bad mic in the W520. The mic in my new W520 is horrible and useless for any voice recording (Skype, etc...). I went into the Control Panel and was able to find the SmartAudio HD drivers for the built-in mic. Uninstalled it and rebooted. Somehow, after the reboot, the Conexant SmartAudio driver is right back. There are no VOIP settings or anything. Not sure if the Conexant driver is the default Win7 driver? How do I fix the bad mic?
Thanks,
jelin

Yes, the mic on the W520 is probably the worst mic on a notebook in existence, saving them perhaps $1. I recommend that you re-install the drivers, then in the (not very) Smart Audio app:
The mic is still bad, but now at least the other end can hear your words rather than "bwa-bwa-bwabwa" which is what you get out of the box.
I recommend going out and buying a USB headset like the excellent Logitech 960 for £16 from amazon.co.uk , and using a different notebook for skype conference calls with multiple people - perhaps a Mac or a Dell just to rub it in. If you dont want to carry round a second notebook, then the Polycom Communicator C100 (£100) is excellent for skype conferences in a large or small room. If I had the cash I would get one of these for home too - the quality is amazing.

hi, jelin-social
1st, try disabling any Microphone VoIP optimization in conexant
2nd, go to Control Panel > Sound > Recording > Microphone > Advanced
Change to the highest Bits and Hz as possible.
3rd, reduce Microphone Boost level and increase mic level to compensate a bit.
Alternatively, if you have time. I would welcome you to try this driver / optimization for improvement of speakers and microphones with Dolby Home Theater v4, more customizable than Conexant SmartAudio.

So far I am satisfied with the speakers and microphones for my W520, it should be great as it provides dual mic. Maybe you should test out my advice to see if it helps, if problem persist or worsen before using alternatively, there might be a problem with the mic and perhaps you may contact Lenovo Technical Support.

hi, eos
If I did not remember wrongly, when I was using Conexant
My Configuration was this
- Disable Listen to this device
although it would not project out your voice to speaker, but it would project out clear voice in Conferences
Enabling this messed things up. Unless your mic volume and boost is very low or the mic is faraway from the speaker.
Normally, I would set it as
Microphone - 100%
Microphone Boost - 10% or 12% (Dolby driver)
If not, I would set it as
Microphone - 50 - 100% (varies)
Microphone Boost - 20% or 24% (Dolby driver)
Go to Control Panel > Sound > Recording > Microphone > Advanced
Change to the highest Bits and Hz as possible.
The 2nd portion helps me a lot. I have done a lot of Skype Conference with different laptops and so far this is one of the nicest mic I have for laptops. Maybe you need different calibration / settings for your environment.
Best Regards 
Peter

Hello PeterTWJ,
Thank you for all of your tips. I believe I have resolved the issue. I went to Control Panel > Sound>Recording Tab>Select Conexant 20672 SmartAudio HD>Properties>AdvancedTab (changed to 24 bit, 48000 Hz) and Disabled audio enhancements under Signal Enhancements. I believe it was really the "signal enhancements" feature checkbox that did the trick. Once I disabled it, I placed some test Skype calls and the playback was really clear!
I played around a little with the Boost and Microphone level but didn't feel that it make too much difference. All is well now!
Thanks again,
Jerry

Hi,
I wrestled with this [issue] too, as end users complained about the quality of my voice and excessive background noise (until grudingly plugging in a headset). After uninstalling Conexant's SmartAudio HD drivers in favor of Microsoft's stock HD drivers, I noticed much improved mic quality (I use level 90, mic boost +12dB, 24-bit, 44100 Hz), and much improved audio output. I just finished a flawless Skype call using a the built in mic without having to repeat myself a single time (yay).

I managed to sort out the issue by removing the Conexant 20672 SmartAudio HD driver. Then Windows just installed its own simply driver and since then everything works very well for me.
