You can switch off programme recommendations (which are based on what you've listened to) by switching off personalisation altogether in your 大象传媒 account settings. For more information on how to do this, visit the聽.
Bear in mind, switching off personalisation will also switch off the ability for 大象传媒 Sounds to remember how far through a programme you are so you can pick up where you left off. It will also remove personalisation within 大象传媒 iPlayer, which you can read about here: Personalisation in 大象传媒 iPlayer.
It may take a little while for any changes you make to come into effect, but you can speed things up by signing out of your 大象传媒 account and signing back in again on all the devices you're signed in on.聽
