Hello,
i got an Onkyo TX-NR686 which has no sound in DTS, TruHD and ATMOS modes.
If i watch a movie with an ac3 track or YouTube, it works just fine and also music streaming works.
The digital mainboard is relativelay straight forward and has an Cirrus Logic CS49844A-CQZ Dolby and DTS decoder chip, which i suspect as the culprit here.
Has anyone ever attemted to replace one of those, or is there a flashed setting on these?
Unfortunately its impossible to get the datasheet for this DSP.
Do you think that reflow might help?
