Troubleshooting
No sound, audio that waits for a tap, stems that take a while, the sync badge and notices, the demo limit — and what to do about each.
| Symptom | Likely cause & fix |
|---|---|
| ▶ Tap to start audio after a reload or a link straight into a module | Browsers only start audio after a tap. The screen is there; tap once and it plays. |
| "Audio paused — tap to resume" banner | The browser suspended audio (usually after you switched tabs or apps). Tap the banner; playback resumes. |
| No sound on iPhone or iPad | SoundSense asks iOS to play even with the ringer switch on silent. If you still hear nothing, the "No sound? Check your ringer switch." hint appears: flip the switch, check the volume, and play again. |
| "Audio unavailable" screen | The browser does not support the Web Audio API. Use a recent Chrome, Firefox or Safari. |
| A question sits on Loading stem… | Stems are being fetched for the first time. They are cached after first play, so the same material loads instantly next time. |
| "This question's audio didn't load." | The connection dropped while a stem was loading. Tap Try again. |
| "An audio file didn't load — this round uses a stand-in sound." | A stem could not be fetched, so this round plays a synthesized stand-in instead. Check your connection; the next question loads normally again. |
| Answer chimes annoying | Tap 🔊 Cues on in the top bar or inside a module to switch them off (🔇 Cues off). It is one switch for the answer cue sounds; the training audio is not affected. |
| Badge "Not synced yet — saved on this device" | Your progress is safe on this device and goes to your account as soon as the connection is back. Nothing to do. |
| Badge "Sign in again to sync" or toast "Sync paused — please sign in again" | Your session ended. Sign in again; progress made in the meantime is kept on the device and sent when sync resumes. |
| Badge "Sync is off — licence" | This account has no SoundSense licence (for example in the demo), so progress stays on the device. |
| Badge "Signed in as someone else — reload" | Another tab signed in with a different account. Reload to continue with that account. |
| "Cloud sync is full — progress is saved on this device only" | Your account storage is full. Free some space on your account page; local progress is unaffected. See Account sync. |
| Progress differs between two devices | Sync merges record by record, so an offline device no longer overwrites anything. Give the second device a moment online, then reload. |
| A module's difficulty picker is greyed out | Intermediate needs 50 correct answers, Advanced 150. The lock shows how many more you need. |
| 🔒 Blind — Advanced only on the mode toggle | Blind mode exists in the four EQ games only, and only at Advanced difficulty. |
| The Ring-Out Simulator is locked | It unlocks at 150 correct answers in total. On a phone it works like everywhere else — see Ring out a wedge in the Ring-Out Simulator. |
| The Daily Shift card says it is done, but I did not finish | Direct links to the shift bounce back to the dashboard once today's shift is complete. It resets tomorrow. |
| Demo · used up today | The demo gives 5 questions a day in each of the five mix modules. Come back tomorrow, or buy SoundSense to open everything. |
Headphones or speakers?
Binaural Beats needs headphones: each ear has to get its own signal, and on speakers the two channels mix in the air before they reach you. The sub-millisecond cases in Haas Effect need them too, and the hearing check strongly recommends them. Phantom Center and Precedence Effect are loudspeaker effects — they work on speakers, and headphones reproduce them. Every other module works on decent speakers.
After a platform update
The tool caches its own files. If something looks stale after an update, fully close and reopen the tab. Your progress is stored on the device and, when signed in with a licence, on your account.
