iPhone 5, current iOS (7.0.4) but this issue has been going on since iOS6...
I don't get the sound alert for incoming texts. I get texts so infrequently, that it's hard to pin down any cause/effect. The phone will vibrate, not not play the configured alert tone. The phone does play the correct ringtone for inbound calls. It's set to vibrate both when on silent and not.
If I test the tone in the sound settings, it will not play. Do a full reboot of the phone and now the text alert tone will play. Then when I next get a text, it does not.
I have in the past tested with different tones, both custom and built-in, to no effect.
