This is the driver for the onboard sound for the Jetway 531cf motherboard
I found it at www.jetway.com.tw/evisn/download/driver/index-2.htm but it downloads very slowly (with many download errors)
"Many many thanks for this (upgrading an old pc for my daughter)" Me too!
[I later discovered a more recent version (22.214.171.1244) at www.jetway.com.tw/evisn/index.html (8738_wxp.zip)]"
