Xiaomi 17 ultra CN rom audio issue
Has anyone else experienced random speaker/audio glitches on HyperOS/Xiaomi phones?
I have a Xiaomi 17 Ultra (China ROM) and since day one I’ve had this weird issue where the phone speakers randomly become distorted/muffled, almost like underwater audio. Sometimes one speaker sounds wrong, notifications sound broken, Instagram Reels glitch, alarms sound weird, and even phone calls can get affected.
The strange thing is:
- it happens randomly,
- Bluetooth earbuds seem completely fine,
- and reopening the app or reconnecting the call usually fixes it instantly.
Example:
One Instagram Reel sounds normal, I swipe to the next one and suddenly audio becomes distorted until I close/reopen Instagram. Same thing can happen with notifications or calls.
I already tried:
- rebooting,
- switching between Dolby Atmos and Xiaomi Sound,
- disabling immersive sound,
- clearing app cache.
Nothing fully fixes it.
This really feels like some HyperOS speaker DSP/audio routing bug rather than physically damaged speakers, especially because it recovers instantly after restarting apps.
Has anyone else experienced this or found a fix?
