I am using exoplayer for playing videos .And for this we are used Fragment instance with pagerstateadapter and viewpager2. But when scroll fast previous played video sound listen in background as well as in screen video means mix the sound in same video player. Please help me how to solve this.

1.State adapter

class StoriesPagerAdapter(
fragment: Fragment,
val onClick1: VideoItemAdapter.OnItemClicked?,
val onlikeClick: VideoItemAdapter.OnLikeCLicked?,
val onFollowClick: VideoItemAdapter.OnFollowCLicked?,
val ontrendingClick: VideoItemAdapter.OnTrendCLicked?,
val oniconCLick: VideoItemAdapter.OnIconClick?) : FragmentStateAdapter(fragment) {
val dataList:MutableList=mutableListOf()
override fun getItemCount(): Int {
    return dataList.size
}

fun addAll(movies: MutableList) {
    for (movie in movies) {
        add(movie)
    }
}

fun add(moive: Gettrendingvideos.Data.Postlist) {
    dataList.add(moive)
    notifyItemInserted(dataList.size - 1)
}

override fun createFragment(position: Int): Fragment {
    return StoryViewFragment.newInstance(
        onClick1,
        onlikeClick,
        onFollowClick,
        ontrendingClick,
        oniconCLick,
        dataList[position]
    )
}}
