I just made a perfectly clear Skype call on my HP Touchpad running CM9.
No video, but the audio worked great!
More info coming soon!
Are you daring enough to try this VERY EXPERIMENTAL MIC FIX?
Flash this zip file from CWM or TWRP and test all you want.
Just to be VERY clear... this is NOT guaranteed to work, nor is it supported. Flash at your own risk.
Also, I hope that you all share your experiences in the REVTV Forum. Any feedback will help in making it better!
I have remove the link to the mic fix as it has been removed. The mic fix has been officially incorporated into the recent nightlies. It you do not have a working mic, and would like to, please upgrade to the most recent nightly build and enjoy!
