Upgraded to Windows 10 on day one of public release. All my sound drivers were blown up by the experience, but over the last month MS have released various fixes which have solved most of the problems, but I’m still having continuing problems with some usb sound devices. I’m currently listening to Spotify Premium streaming to my SoundMate M1 connect to my amp/speakers setup. Usual 3+ seconds delay, but great quality even at window-shaking levels. MS appear to be working hard on the sound SNAFU with Windows 10, but it obviously wasn’t as ready to go as other parts of the upgrade. I have manually checked for updated sound drivers for all my audio devices (I have several all doing different tasks) and this looks like it was worth the effort.
