The BDP-10x series of players are capable of bitstreaming Dolby Atmos content to a receiver that is capable of decoding Dolby Atmos. In order to ensure that the audio is being output appropriately from the OPPO player, please use the following settings:

Change HDMI Audio to Bitstream

1. Go to the Setup Menu and then Audio Format Setup.

2. Select HDMI Audio and choose Bitstream.

Ensure That Secondary Audio is Off

1. Go to the Setup Menu and then Audio Format Setup.

2. Select Secondary Audio and choose Off.

Typically, you will need to have a Dolby Atmos setup in order for your AV receiver/processor to display that it is receiving a Dolby Atmos audio stream. Otherwise, it may indicate that it is receiving a Dolby TrueHD audio stream.
