Hello @DYSPROssium.
It happened to me since I bought the game (August 2018), so I've reinstalled all the S.O, and drivers up to date.
And now, its not like before the sound completely shutdown, instead, I have some randoms cuts, that it can ends in a total lost of sound, or cuts every 20...30, x seconds. The temporal fix, is exit BF2 and restart the program.
But, it's annoying, because it means you should quit from your actual match, or just playing listening the cuts the entire remaining match.
I am not sure, but I think I had 1 week with no sound problems, 2 updates before this last patch, and now this issue is back.
I have Maximus VIII Hero with the latest drivers from ASUS web page.
I will try to rollback the sound drivers to the windows version, to see if the problem disappear, but as I am seeing ppl complaining about this issue too, so what would be the common thing between who suffers this sound issue?
Kind regards,
