Issue: There is no sound from the glasses' speakers

Solution:
1. Check the phone's volume and make sure it is not muted.
2. Make sure the glasses are connected to the phone via Bluetooth. In the phone's Bluetooth settings, make sure both Call Audio (HFP) and Media Audio (A2DP) are enabled for MemoMind One.
3. Clean any dust or debris from the speaker area to make sure it is not blocked.
