Salaam maulana sahaab,Is it ok to play audio file of Quran at home while we are busy with other work and not listening to it.Just wanted to play for barakat and a nice environment in the house.

Walaikumussalam
If it is not causes to disrespect of the Quran then it is allowed.kindly try to read the Quran and translation and teach Quran to children
Wassalam
