which dates back to Windows XP or Server 2003 ! 'UAA' 1.1 UAA Function Driver for High Definition Audio Service' Re-installing Windows 10, with Wi-Fi disabled, it seems the default generic Audio drivers are I haven't tried running the installers in 'Compatibility Mode' - that has worked for the Fingerprint sensor!Įvent Viewer only shows 'Success' - 'Staus 0' Information-level events. I've tried many drivers without success - Windows 8 and 8.1 here Sometimes the speaker and mic appear separately as 'Audio Endpoint' 'Device Manager' reports 'Realtek High Definition Audio' I use Windows Sounds control panel system sounds to test. When I say 'buzz', I don't just mean a gentle 'mains hum' behind the sound, but a very loud sound like a 50Hz square-wave instead of the sound, even with 'Volume turned down to 1'. Shows green for 'VPCZ2*' for Audio (and everything except 'touch' which hardware it doesn't have)
The odd thing is that both microphone and speaker work OK before Win10 specific drivers are downloaded ! (I don't have a Sony DVD, but restoring from the Recovery Partition also buzzed) It even buzzed under a fresh Windows 7 install from Microsoft DVD media I'm trying to upgrade a Vaio Z2 VPCZ21v9e to Windows 10.
