I'm trying to find out if the sound card (chip set) in the Acer Netbook AOD 260 is only half duplex or does it support full duplex? Don't see anything at the Acer site, and nothing mentions if it is or is not capable of full duplex operation. I also see nothing in the setup or configuration of making it work full duplex. I'm really hoping it is capable of doing so, if it doesn't it'll be the first time since I bought it a few years ago that this little Gem has let me down. The ONLY draw back I find is the keyboard is too small to do any fast typing. No big deal when I absolutely need to type fast I connect an external USB Keyboard. This is not my main computer, it's used for very specific reasons and does very well doing that.
