We can say all things here but please see: https://answers.ea.com/t5/Bug-Reports/Audio-loss-during-gameplay/m-p/9015168#M26920
This is a topic I created where you see Windows sound is ok. No driver issue at all but just audio is loosing while playing.
So yes we can handle this as technical issue and see where to improve the players system. But I think this is also proof a bug rarely occurs where audio just is lost.
@moccor @ , I would advice you to check audio into BFV and see if you get different results by changing for example 3d headphone in speakers etc.
