if you got the issue that your Surface RT with attached Touch Cover mutes the sound randomly, you should check out this post and advice in the Microsoft Answers-Forum:
They are still working on that issue but they know already that it has to do something with the Touch Cover.
Because of that they want you to exchange the Touch Cover (if you got this issue) through the Store Support.
I have a Microserver N54L with a 2.2GHz processor. Is there an upgrade to this processor?
What would be a good sound card for this box? (Note: I have Windows 10 installed running PLEX Server)
To attach a monitor with speakers to a MicroServer N40L/N54L with HDMI and stay within the 25W limitation on the x16 slot I was wondering what cards are people actually using?
I'm thinking of repurposing a MicroServer for a family member (their computer just died this morning) running Windows 8 but I need to provide sound and I need to plug in a HDMI monitor.
