Increasing this value will give more chance for less stable connections to be established.
config A2DP_DISCONNECT_MS
int "Time in ms before disconnecting from A2DP audio sink. Set to 0 for no disconnect."
default 10000
help
Controls how long to wait before disconnecting from the A2DP audio sink after playback is stopped
Longer delay will ensure better responsiveness at the expense of locking the audio sink for a longer period.
A shorter period may cause the player to disconnect between tracks change.
