Perhaps it wasn't the most intelligent computer decision I've ever made, but I have an old HP nw8440 Mobile Workstation that i installed Windows 8.1 onto then installed Windows 10 Technical Preview on. So far so good. But last night Microsoft installed the newest version upgrade and it needs to re-install SoundMAX inorder to give me back my audio. What drivers and such do I use for thios OS, because HP only has drivers for this laptop model up to Windows Vista? If anyone can help I would appreciate it.
