Title: HDMI AV Pass-through in Standby Mode Workaround
Earlier this year, Tidal announced the availability of Dolby Atmos Music. Since I first heard the news, I looked for a low-cost way to give Atmos Music a try. Now with an Amazon Fire TV 4K Stick (~ $49) as a source, I've finally had the chance to experience Dolby Atmos Music on Tidal.
I've always used the Realiser primarily for 2-channel listening. While my A16 2-channel experience has been nearly identical to the A8, my Atmos music experience has been quite different. How the two formats compare is a topic for another day. But what I'd like to share today, as I eluded to in the title, is a workaround for an A16 issue that I've experienced, and I believe others in this thread have also encountered.
The A16 annoyance I wish to discuss is its inability to pass-through an HDMI input AV signal while the A16 is in standby mode (i.e., powered off). Having to keep the A16 powered on to pass-through an HDMI signal even when I'm not using the A16 is an inconvenience. The workaround solution I employed requires the use of an HDMI splitter. However, the full solution required an overly complicated combination of hardware, HDMI settings, and resetting sequences, which I've detailed below.
At least for me, this workaround achieved the result I need until Smyth Research can implement a permanent solution for a passive HDMI pass-through feature. It's important to note this fix is only applicable for single-source systems. If support for multiple input sources is required, another approach would be needed. I'm aware that other configurations or solutions may be available to achieve this goal. However, as I mentioned, this particular workaround works for me in my system. Your mileage, of course, may vary.
Hardware
- LG 47LE8500 TV
- OREI 1x2 HDMI Splitter(UHDS-102) ~$25
- Realiser A16 (Firmware 1.81)
System Configuration
Setup Steps
1. Power on the FireTV4K/LG TV combo.
2. Power on the A16.
3. Navigate to the HDMI Settings page and turn ON Audio Bypass (Press the Menu key, Scroll to Settings, System, HDMI Settings). In my case, I would lose audio to the TV.
4. Restart FireTV4K (Audio to the TV would return).
5. Restart a track in Tidal.
6. Turn OFF Audio Bypass (audio to the TV should stay on, and SVS audio to the A16 should start).
7. Power off the A16.
At this point, the HDMI AV signal to the TV should be fully functional, and the A16 should be in Standby mode. This solution may also work for a connected AVR or Soundbar, but I've yet to test either of those other devices.
I'm curious to know how other A16 owners have addressed this issue, or whether this is even of concern to others. If you've implemented another approach that works, I'd love to hear about what you did in your situation.
