old post but will do an update. ( i found the chip is CMI8738SX) (my pci port scanner and mag light , looking)
, are basic speaker 2 channel ok. but mic dead. turn on mike test. and BSOD.
2012 install drivers off board mfg site Sabrent SBT-SP6C
for Windows 7 32bit, install says, wrong platform. setup.exe admin mode.
so i tried vista. , it installs and works and get NEW nice sound mixer.
microphone starts working very well, and i can use Skype, but if you click the MS task bar speaker icon, BSOD. BOOM, like clock work. ( a bad driver
i did find the drivers at CMI web site and will test them.
all i need is 2ch, audio speakers and mic, noting else, needed for skype.
the Sx is only 4.1 channels, the LX and MX are 5.1 and MX has SPDIF out.
what ever MS certified , its not this driver. for the record. more later. on oem chip drivers.
imo, 64bit is hopeless if 32b is DOA.
