How to change the audio format of your Samsung TV
Note: The provided information refers to Samsung Smart TVs sold in Canada. The available settings and options may differ for devices sold in other countries.
Note: This changes the signal to 2.0 PCM as it passes through the TV. If you select PCM even though you have a home theater system or soundbar connected, the sound system will only receive 2.0 channel sound and the result will not be multi-channel surround sound, even if the sound system is capable of multi-channel PCM audio.
Note: If you select Bitstream, but do not have a home theater system or soundbar connected, then the TV will process the audio in addition to outputting it. This can often result in reduced volume or other loss in audio quality. We recommend to select PCM when using the TV's speakers.
Note: If settings are grayed out, it may be because the content you are currently displaying on the TV, or the source you have selected, does not support that output mode. For instance, in the Hulu app, the Dolby Digital option may be grayed out when browsing shows, but once a selection is made and you are watching the show, the option becomes available.
Note: Settings higher than Dolby Digital, such as Dolby Digital+, require more bandwidth than an optical cable can support. To enable these settings, connect the home theater system or soundbar via HDMI ARC for greater bandwidth.
