Record the complete web playback arrangement
Note the Mac model, macOS version and browser actually used for the concert. Do not reduce that record to simply Mac or Apple. The official wording says certain computers, so meeting the operating-system version alone should not be read as a promise that every model qualifies. Retain the current service requirements alongside the model identification.
If the same concert was opened from an email in another default browser, record that route too. Comparing an ordinary video session there with an Immersive Audio instruction written for Safari mixes two arrangements. The relevant comparison keeps the concert constant and identifies the browser before changing global sound or account settings.
Inspect the concert player’s audio choice
On a qualifying setup, Digital Concert Hall directs viewers to the player’s cogwheel to select audio quality. It also says that choice is saved for the corresponding device until changed. Check the current player choice rather than assume a preference made on a television or phone has set the Mac to the same format.
Keep availability, selection and audible output as separate observations. A remembered setting is not a measurement of what a receiver or headphones currently reproduce. If the desired option is absent, record that fact accurately; do not label it a failed audio stream that was never selectable in the first place.
Give support a format-specific report
A useful enquiry includes the exact concert, computer model, system version, Safari version and visible audio choices. Describe whether ordinary sound plays and whether the issue is an absent option, a choice that does not persist or silence after selection. These details focus the question on the service’s specific web-audio route.
If another already available supported route offers the desired format, preserve that as a separate comparison. It does not change the Mac’s requirements or prove the first browser is defective. Resolve the documented route and device conditions before replacing equipment or repeatedly resetting an account that already plays ordinary concert video.
