Hi everyone,
I hope someone can help me out with this issue. Please feel free to remove this post if it’s not appropriate for this forum.
I recently purchased a Sony XR55A80L TV and connected it to a TA-AN1000 amplifier using eARC. I’ve gone through the amp’s easy setup process and double-checked various settings on both the TV and the amplifier. However, I’m encountering an issue with DTS-HD Master Audio (DTS-HD MA) not being properly decoded.
When I set the movie's audio to 5.1, the amplifier correctly displays and decodes the 5.1 audio. But when I select a higher-quality audio track, such as DTS-HD MA, the amplifier shows that the audio is being downgraded to Dolby Digital Plus (DD+) 2.0.
I’ve tested this using both Stremio and Kodi installed directly on the TV. I’m using a high-speed HDMI cable, and as far as I can tell, all settings on both the TV and the amplifier are configured correctly.
To rule out any cable-related issues, I plan to try another HDMI cable.
One thing I’m unsure about is whether my TV supports DTS-HD MA decoding from installed apps. According to the manual, the TV supports passthrough of major formats, including DTS-HD MA, via eARC. However, I’m wondering if the issue could be that these formats are only supported via HDMI inputs (e.g., from an external Blu-ray player) and not from apps installed on the TV.
Here’s the list of pass-through audio formats supported with eARC as per the manual:
- 7.1 channel linear PCM: 32/44.1/48 kHz 16 bits
- Dolby Digital
- Dolby Digital Plus
- DTS
- Dolby TrueHD
- DTS-HD MA
- Dolby Atmos
- DTS
Master Audio - MPEG2 - AAC/MPEG4 - AAC
Has anyone experienced a similar issue or have any insights into what might be causing this? Your help would be greatly appreciated!
Thanks in advance.
