Hi ​@Yurii M 

Thanks for your post. Apologies for the trouble. In order for audio cues to work, please try the following troubleshooting tips:

• Try reinstalling the Strava app and restarting your phone.
• Audio cues are only available for runs or rides. Cues are not available for other activity types (i.e. walk, hike, e-bike).
• Double-check that your audio announcement settings are still enabled. Occasionally, your recording settings will be reset if you log out of the Strava app. 
• Ensure that your media volume, not just your ringer volume, is turned up to an audible level.
  • Android phones often have three or four settings for volume. Try turning them all up.
  • You can also put on some music to confirm the volume is on. When music is playing, “media” volume will be used. If no music is playing, ringer volume will be used. Also noteworthy, ringer volume may not play through Bluetooth headphones.
• On Android phones, check your Text To Speech language options and confirm the preferred engine matches your system's language preference.
