First of all, the front row is inserted

Before you start, you know RT5. You can only say one thing. There is a difference from a real home theater. Frustrated fancy its appearance, wireless surround (no audio cable embedded in the decoration), comes with Bluetooth and NFC, support for ARC control, support for 4K, etc., plus the living room TV is Dafa 8000c, so the faith recharge ......
Out of the box? ? ? No no no
Because someone had already opened before, I will not open. Everyone needs to look out of the box. Please move to:



The pseudo-opening box that is shared today is actually a method to solve the problems caused by equipment interference and abnormal operation when using HDMI backhaul and CEC control.
As mentioned earlier, the TV in the living room is Sony 55X8000C, and HDMI 4 supports ARC. The first time RT5 got home, I was plugged in. Well, I plugged in the HDMI4, and HDMI1 always plugged in the 4K IPTV box (Hengfeng HG680-J) sent by telecommunications, HDMI 2 plugged in the xbox 360, and HDMI3 plugged in the PS4. Well, the back of the butt is already full.
Put the RT5 in position, connect the tuning microphone and tune it. Open KODI and select a movie that supports the 5.1. Everything is normal.
Shutdown, what? TV off, RT5 is still in TV mode without standy? Probably my setup problem? Turn on the TV to enter the home mode, a pass setting ... or not ~! !
Constantly tossing, using the exclusion method to find the IPTV box inserted all the year round, if the standby state, ARC and CEC will not work properly, will even go to it, work, ARC normal, but CEC is still not available.
Telecom's HG680-j does not support CEC. But finding the problem is easy to solve. Turn off all devices, pull out the HDMI cable on the IPTV box, find the tape for electrical tape, cut out about 1-1.2mm wide tape with scissors, and put it on the 13th signal line of the HDMI port. Fingers do not get into the thick plug, find the root toothpick to try ~
The 13th signal line position is as shown in the figure:
Well, after plugging it in again, all the equipment is working properly, and no CEC or ARC work is normal anymore. After a while, it seems that many set-top boxes and network players have such problems. Obviously they do not support CEC, but they also do not comply with the HDMI standard and actively shield it...
So...When any CEC or ARC is working abnormally, look at the HDMI port behind the buttocks and plug in the device. Do not change the HDMI line with the 13th signal line to try it out. There may be a surprise. !
Finally, add CEC and ARC explanations
CEC, full name is Consumer Electronics Control, Consumer Electronics Control. The CEC function brings many conveniences to the user. It allows the end user to use a remote controller to control a plurality of CEC-supported HD devices, thereby eliminating the need to use multiple remote controllers to control electronic devices such as televisions (TVs), set-top boxes, and portable HDs. equipment.
The HDMI-CEC function is generally based on the CEC signal to allow the user to control the connected device on the HDMI interface. For example, One Touch Play, System Standby. That is, if the user puts the DVD player into the Blu-ray player, the television will be automatically turned on due to the notification of the CEC signal, and then the video channel will automatically switch to the channel connected to the player. When the user turns off the TV, the CEC signal also notifies the HDMI-connected device to enter standby. Because of this, it becomes completely a single remote controller to control all HDMI-connected devices.
Audio Return Channel (ARC)
TVs with a built-in tuner and HDMI interface can "upload" audio data to a surround sound system without the need for additional audio cables. In the case of high-definition televisions that directly receive audio and video content, this new channel allows HDTVs to send audio directly to the A/V amplifier receiver over an HDMI cable, eliminating the need for another cable.
