I just bought Acer Iconia W510, Skype was preinstalled there.
I have a problem with sound level - it is very quiet, I almost cannot hear anything.
Strange, but I have no such a problem for other programs on this tablet.
I tested with Test sound service - its voice at first is okay but then in 2-3 seconds became much quiter.
My recorded voice is always almost inhearable at first and in 2-3 seconds became unhearable at all.
But when I look in Skype settings - voice levels are shown fine.
I tried to change shared.xml file, added there <DisableAGC>1</DisableAGC> in <Audio> section and <AGC>0</AGC> in <VoiceEng> section, but without any success.
Please help if somebody knows how to fix this problem.
I found the solution of the problem. It happened because I installed the newest version 2.08 of Acer firmware from page http://support.acer.com/us/en/product/default.aspx?tab=1&modelId=4549 After I downgraded a version to 2.04 Skype works perfect. Hope it will work to others.
