Can you give me a step by step procedure to connect my PC to my tv and/or whole house audio using ROKU and PLEX

;;search for:
"How to set up a Roku TV " on youtube

gee did it ever work before or just found a used ROKU in a garage sale>?
NO system stated, at all, what do you have connected before you, (endless possible for sure)
so I will do wild guessing,
I first guess you have old TV that is not SMART, so no Netflix player s there.
so you buy a ROKU, (I have 2 love them, more on that later)
is this a new RUKU or old.? if old you need to upgrade the firmware on it per your manual,
The ROKU news version self upgrade them selves and also upgrade app players all the time, so that new feature work, using say the * star button,(settings for many things)
min upgrades as I sleep, ROKU is the best there is, so good it is installed inside newer TVs now, yah it works that good.
NOT TV made works that good unless it has ROKU in it, OK???
see why, (answer the new apps update all the time, endless)

what does not respond mean
does the RUKU player work , on the main right side screen of ROKU, and MUST work on their web player channel this would be first test, not Netflix using logic of walk first then run.

Then see of you internet connections work. If the ROKU channel is dead, internet is next , mine has wifi and ethernet channels.
I use the latter, and NEVER FAILS, and we all know wifi is PITA.
(of 1000 reasons)
But you have wifi , I bet and that is a pain, if to far or too slow or the wifi channels are all overloaded by others in home or close neighbors (so move to higher wifi channels)>?

Tell again what "NO RESPONSE MEANS"
elaborate on just that,
1: the menus are missing , black screened?
2: what does not respond, exactly, what.?

on mine I use PLEX and I click PLEX and my PLEX server comes up. wow PLEX.
there are like 100s of APP players there are all dead/?

lost the free manual? it has simple instructions.

no RoKU stated model, saying just Roku means nothing, oK>
it has a real name and model, just like you unstated TV.
lots of Roku)
I have the Ultra (non Dongle) not the STICK.
mine is (best) a floating box. with 1 AC power pack (see?)
and is not optional.
first is power, the Ruku must have power.
then on mine power light on the roku glows
next is internet
and last is hdmi connected to TV.

Power, then internet and hdmi.
finally is TV set to TV's hdmi port number that is ROKU.!
if our ROKU is only a streaming stick (DONGLE)
it steals power from the TV HDMI port.


mine is ethernet connected for max performance

my guess is you have the TVs input selector set wrong
wide guess blind to true MODEL I am, non stated
good luck
and nothing beats a ROKU,
for 1 reason the player apps in it all work and are updated for free.
That is why TVs no come with ROKU inside for that 1 reason.
I use ROKU plex and to my own private servers.

The Roku itself doesn't have the capability to stream directly from PC but with a help of a channel, you will be able to stream files from Pc to Roku. You can check out the PLEX Channel. To know more about the channel, you can visit, www.plexapp.com on your computer.

The Roku doesn't have a capability to stream from PC directly to Roku. But, with the help of a channel, it is possible. You will be needing PLEX application to enable it. You can visit www.plexapp.com to know more about the channel.

The Roku doesn't have a capability to connect to a computer. But, there's a way for you to access files saved on your computer such as videos, photos and music and that's by adding a channel on Roku. You can add PLEX channel on Roku and use it. To know more about the channel, you can access plexapp.com.

If you want to hook up the PC to play media, I suggest you install software called Plex for free (plex.tv). The Roku has the Plex app so you can play through the Roku or most smart TVs, Amazon Fire, or directly via an HDMI cable from your PC to the TV. It will automatically sort your media once you go through the setup and it is probably the best variant of the KODI/XBMC media systems out there for all platforms.
If you want to record from your DVR to your PC, that gets more complicated. The HDMI cord usually has certain protocols that keep you from recording copyrighted programs DMAC (Digital Media Access Control) so you'll need a video input card that has RCA inputs for red/green/blue or a yellow video input and either a red/white RCA input for sound or an SPDIF Infrared (IR) sound cable and use the software that comes with the tuner card.
