Audio is always PCM instead Dolby

Hi there brvaland,

A warm welcome to the Roku Community!

Enabling CEC and ARC is different for every TV brand. Some have separate settings for each, while others combine the features into one setting that turns ARC and CEC on or off at the same time. When looking through your TV's menus for these features, understand that manufacturers may not refer to them by name, but rather as part of a branded trade name. In general, you can often look in a "settings" menu for CEC-related settings, sometimes in a "system" or "advanced" submenu. ARC-related settings may be located in the same place, or they may appear separately in an "audio" or "sound" menu.

• LG (SIMPLINK)
  Note: SIMPLINK must be enabled using the CEC steps before you can enable ARC
  CEC steps:
  1.Hold Settings on your LG remote for 5 seconds to open the Settings menu
  2.Select All Settings from the bottom right corner of your display
  3.Select General from the left menu
  4.Select SIMPLINK (HDMI-CEC)
  5.Set SIMPLINK (HDMI-CEC) to On, and confirm
• ARC steps:
  1.Perform LG CEC steps 1 and 2
  2.Select Sound from the left menu
  3.Select Sound Out
  4.Select Audio Out (Optical/HDMI ARC)
  5.Set Digital Sound Out to Auto
