Read the whole output label
Google's streaming-device audio guidance distinguishes a PCM stereo choice from the broader PCM description. Do not remove stereo from the option name and assume it preserves every source channel.
Conversely, seeing PCM on equipment is not enough to declare that only two channels are present. The exact route and reported channel layout matter.
Separate source, decoding and output
A multichannel source can be decoded before leaving the player, while another configuration passes an encoded signal onward. The receiver sees the output it receives.
An output representation is not a direct catalogue specification or proof of the original track's channel count. Keep the app's selected track information with the equipment display.
Use a controlled route comparison
Identify TV speakers, headphones or receiver and the connection. Android's developer guidance makes audio capabilities route-dependent.
If a supported stereo fallback restores sound, record that limited result. It can narrow a compatibility question without proving the original source is defective or every surround configuration unsupported.
Check the listening task
Use a permitted familiar passage at comfortable volume. Confirm dialogue and the intended output rather than judging only the largest format badge.
Language and audio description are separate track choices. A correct PCM output does not identify which dialogue language was selected.
Report channel evidence explicitly
Give support the source label, selected output option, equipment and reported channels where available. Say unknown when a display offers only a broad PCM word.
No audio route or IPTV source was tested here. This article explains representation versus channel layout and does not promise a particular codec, lossless source or speaker result.
Keep a fallback tradeoff visible
A manual setting can solve an immediate listening task while changing channel layout or processing. Retain its exact name and the original value so the household understands what was chosen. Do not describe every audible fallback as full surround restored. After a successful comparison, test another ordinary source and confirm the setting remains useful. This prevents a narrow temporary workaround from becoming an undocumented global preference that later makes a different application appear to have lost capabilities. Keep the original automatic choice available when comparing a manual fallback.
