The text and notifications tone volumes are too low! This is a software bug, and Apple either has deprioritized the resolution, or doesn’t know how to fix it. Oh, and for the record, no solutions for this issue work. Including a full factory reset, or even replacing the device. It’s almost as if it’s caused by an app or iCloud setting.
Text alert tones are broken on most pro models, and have been on mine for years. New iPad Pro out of the box, m4, 1TB, top of the line, iPadOS 18.2, text tones at 100% volume, sound level out the speaker is about 16dB. (Whisper quiet) Almost inaudible with normal hearing from 500mm. I can only hear the tone with my ear flush to the speaker at 100%. At 30% a child can’t hear it. At 10% an amplifier at 100db gain can’t detect any sound. why? because the speakers are emitting no vibration at this level. Oh, and the units at the Apple Store perform much better, but not loud enough. So, my guess is it’s a few compounding factors causing this. My iPhone 12 is like 100x louder. Apple, please open a CAPA, you’re losing customers. Please fix this bug!
