Draw the real audio route
Write a short equipment sequence: streamer to TV speakers, streamer to receiver, or streamer to TV and onward to a soundbar. Include the connections. An accepted format at one HDMI input does not establish that a later audio return connection passes it to the final speakers.
Use a permitted reference with a known selected track. Confirm ordinary volume and mute state before adjusting formats. Missing sound on every item is a different observation from sound missing only on one multichannel track.
Use the matching device controls
Google documents supported-format selection under Display & Sound, Advanced sound settings for its Google TV streaming devices. Google TV Streamer additionally has Audio options and Output format, including Automatic and specific choices. Do not assume the Streamer-specific submenu is present on an older Chromecast.
Start with the automatic setting when it works. Manual formats require support in the connected media equipment. Enabling every format listed by an internet guide does not add a decoder to a receiver.
Compare without changing the whole chain
Test the same track and volume through one format choice. If using a documented PCM stereo fallback, expect two output channels; do not treat loss of surround as a surprise. If sound returns only in that fallback, record the result as an output-compatibility clue rather than proof that the source is faulty.
Check Google's device-specific instructions for applying a change. Its Streamer guidance notes that an Automatic change may require a power reconnection. This is a narrow documented condition, not a reason to reset the whole television.
Finish with usable evidence
Verify speech and effects, then another item. Note the selected source track, final output setting and receiving equipment. A receiver badge can reflect an output conversion, so report it alongside the app's track information.
Restore a working setting if a manual experiment causes silence or instability. The outcome is a configuration comparison, not certification of all audio formats, every app or an IPTV Canada account.
Check a route after changing hardware
Repeat the reference when a receiver, soundbar or HDMI port changes. A previously working manual format is not automatically suitable for the new route. Also check the ordinary TV sound input selection: hearing a different input is not an audio decoder result. Keep a simple working fallback recorded so another household member can restore sound without having to reconstruct the whole experiment.
