[Blind-sysadmins] hyper v and audio

Hi. Found the commands to turn on audio end point builder and the audio srv service. But noticed on trying to connect to a third domain, and only got two server running, ahd to turn the third server off, only got 8 gb ram, do have another 8 gb slot free on my vivo book laptop. Notice some times, even though got windows narrator and nvda set on, some times it does not speak, and just says caps lock on and off. Then it will then say the password field after the fourth or fifth reboot. Any ideas why. Using windows 10 pro 64 bit 2009. Thanks. Ps: intel I 7 32.3 or 2.4. ghz quad or dual core pro, up to 6 cores, 8 gb ram, 512 gb ssd. Marvin.
