Requested capability	Surround sound, preferably 7.1

Current evidence

• No current surround-sound capability or dedicated Roku issue was found
• The feasible result depends on Roku device capabilities, codecs, direct play,
  and any server-side conversion path

Discovery checklist

• Document the audio codec and channel layouts present in the Roku playback
  response
• Identify which combinations Roku can direct play or pass through
• Define fallback behavior for unsupported layouts
• Confirm whether server-side conversion changes are required

Acceptance checklist

• Supported surround tracks play with their intended channel layout
• Unsupported tracks fall back without silent playback or an unexplained
  failure
• Stereo playback does not regress
• The supported device, codec, and channel matrix is documented
