Describe the bug

"Ack" sound does not play when an ACK to a direct message is received.

Which device are you using

LilyGO T-Deck Plus

Which Firmware are you using

v0.9.12

To Reproduce

1. "Mgmg" -> "UI" -> "Sounds"
2. Make sure to have "All Sounds": "Enabled" and "Ack": "Enabled"
3. Send a DM
4. Wait until DM is marked as "Delivered"
5. Observe that no sound is played.

Additional context

"Mgmg" -> "UI" -> "Sounds", hitting "Play" besides "Ack" does play the sound (stuttering/ crippled, though).
