Text alert sounds

Hello simoné32,

Thanks for posting in Apple Support Communities. You can change the notification sound for messages using the following guidance from Change message notifications on iPhone - Apple Support.

"Change the sound and vibration for notifications

You can choose the sound volume for alerts, choose between a tone or sound for alerts, or change the notification vibration pattern (when the phone is silenced).

1. Go to Settings  > Sounds & Haptics.
2. Do any of the following:

• Make notifications quieter or louder: Adjust the volume with the slider.
• Choose a tone or sound: Tap Text Tone, then tap a sound below Alert Tones (or tap Tone Store to download one).
• Choose a vibration pattern: Tap Text Tone, tap Vibration, then choose an option (or tap Create New Vibration to make your own).

Tip: The tone and vibration you choose apply to both the Messages app and other apps that have notifications on, such as Mail, Phone, and other Apple or third-party apps. To change them just for the Messages app, go to Settings > Notifications > Messages, then tap Sounds."

Take care.

Hello simoné32,

The link that we provided contains the steps needed to change your alert sound. If a specific sound is no longer available for you to select, then it was most likely removed in the latest iOS update.

If you wish to see it returned, you can certainly leave feedback on this functionality. No one is better qualified to provide feedback about Apple's products and services than the people who use them. The following link will get you started: Product Feedback.

We hope this helps. Let us know if we can assist with anything else at all. Take care.

May be part of the known issues with the text tones (custom and some of the stock ones).
