E540 Microphone too quiet

[warder]

Hi,

I upgraded my E540 to W10 and it mostly went ok. One thing however is not working: the Microphone. It barely works but is so quiet no one can hear me except a tiny bit if they turn their end to 100% volume.

I've tried:

- checking Audio Recording gains/levels are all max
- playing with options in SmartAudio app
- Uninstalling the Windows auto-installed drivers and installing the ones from Lenevo's support website
- Uninstalling those and installing the Windows 8 drivers (didn't work at all)

Does anyone have any suggestions here? Perhaps you've experienced this on another TP and have a workaround?

Many thanks!
