For soundmax users, it is important to uncheck front panel microphone and maybe also microphone boost setting at the advanced settings of microphone in playback and record.the weird thing i did notice though was that microphone volume in record suddenly have a life of its own,lowering its volume by itself. but i still get the error ("An error occurred during direct play voice setup 0x80004005") for that [bleep] control panel\sound and audio properties\voice tab\test hardware button.
regardless, this fixed the mic issue for msn,yahoo chat etc. so we'll wait for final fix for this bug. i am using asus p4c800 mobo with soundmax 4 onboard audio with driver version 22.214.171.12430 I HOPE ASUS updates their drivers for the ASUS P4C800 especially for the soundcard cos i've only seen the 3com drivers are the only ones updated.
