Soundbar 500 will not turn on via HDMI ARC
I have a Soundbar 500 connected to a LG C9 TV via HDMI ARC (HDMI 2). Everything works fine at first, sound is working and I can control the volume through the TV remote. However, after watching a show on TV for a couple of hours without using the remote, if I pick up the TV remote to adjust the volume, it does not work, I have to use the Bose remote to adjust the volume. Once I use the Bose remote to adjust the volume, the TV remote then will work to adjust the volume through HDMI once again. If I don't use the remote for another couple of hours, the problem repeats. The other problem is once I turn off the TV, the soundbar goes into standby mode. After the TV is off for a while, if I turn the TV on using the TV remote, the soundbar will not play audio. I can see the white light on the soundbar lighting in response to pressing the volume buttons on the TV remote, but no sound. If I use the Bose remote and press the TV button, the sound works and everything is fine until I turn off the TV again for a few hours, the problems starts over again. It seems once the soudbar goes to sleep, the only way to get it to respond to HDMI controls it to use the Bose remote to wake it up. This is very annoying, even more so than the Alexa volume annoyance.
