Check your settings in Notifications. Check to see if the Mute Switch is on. Check to make sure that Do Not Disturb is on.
All of the obvious things have been checked and even resorted to the Microsoft standard fix of ‘switching it off and on again’. This is becoming frustrating and I’m now wondering what other problems are around the corner. This iPhone X has many advantages and I really do like it but this issue does not inspire confidence.
Given that the OP or yourself do not indicate any of the troubleshooting that you have accomplished, anyone that responds is going to have to go through all of the troubleshooting steps. I've not encountered anyone experiencing sound issues with their iPhone X, and I've not experienced a problem either.
Are text messages the only sound you do not receive? Do you receive sound notifications when you receive an email? Do you happen to have an Apple Watch paired to your iPhone?
As stated I’ve tried all of the settings changes available, including all combinations but still no sound for text alert. The number and sequence of settings changes are too numerous to list. My phone is not paired with any other device. I occasionally use it as the remote app for my Apple TV.
I have had this issue for almost a year now. It inconsistently gives me alerts for texts and Reminders. I have tried EVERY SINGLE fix, including Apple sending me a new iPhone 7 since they agreed I had tried all possible fixes. BUT...the problem is identical in the new iPhone. Is Apple ever going to fix this problem, as it's obviously a software and not a hardware issue!
I had the same thing and found that when using an activity tracker synchronised via bluetooth, the notification sounds would be silenced. To check this try to change the noise associated to the notification and no sound will be heard. Switching off bluetooth brought back the sounds ! This was true for all notification sounds except Ringtone - which always worked.
I'm using OS 11.3.1
APPLE - Definitely think it's a software issue. The connected device was a FITBIT tracker. Someone has coded the phone notification sounds to be silenced [with no option] when the tracker is connected and in range.
I agree, when I first got my Fitbit all worked well. My phone would ding, the message would appear on my fitbit. Now notifications don't work on my phone and my fitbit doesn't display the texter or text information. My notifications are on, my alert noise is set, I have not hidden alerts for any of my contacts, my mute button is not engaged. As I play with these settings I will always get an alert for the first text, but none of the subsequent messages. Today I tried to disable blue tooth and I got the notification. Oddly enough after disabling bluetooth I also noticed Do not disturb was on, so I disabled that and re-enabled bluetooth. I got the notification, but the text alert was not sent to my fitbit like it used to. I will need to wait to see if I get alerts for any more texts or if it's still only working for the first text after a change.
FYI - My fitbit also isn't syncing properly, my dashboard on the web is correct, but the Fitbit app doesn't display my sleep information correctly. All days show the current day's information. Could be the Fitbit app messing things up. I"ve posted to Fitbit forums about the sync issue and nobody was able to help me (so far).
If you have an Apple Watch paired to your iPhone, then if the iPhone is locked, you will receive the notifications on the watch. See this for how notifications work between the iPhone and Apple Watch. Notifications on your Apple Watch - Apple Support
Otherwise, please better explain your issue.
Question: Alerts do not sound when I receive a text message.
