GSM True Speech Codec. I've never had a problem getting connected to Yahoo Chat before. Right now, Voice won't work for me. The errors I'm getting are: Your computer does not support the required audio compression format." "Yahoo! Voice Chat requires the GSM True Speech codec in order to compress voice data for efficient data transmission. This codec comes as part of your Windows operating system. If you do not have this codec installed, or if it is corrupted, you may need to reinstall the codec." Any help would be appreciated. Thanks.
