Just was racing in the AAL league and lost all sound after 17 laps. Hung on until 22 when flipped to desktop and back to game. By then I was in the sand. Game over.
Did the sound work fine in Windows after the crash? It could've easily been a hardware problem, not necessarily an LFS glitch. LFS never ever glitched on me as far as graphics and sound goes.
When i flipped to the desktop in my 1st pitstop, there was sound for like a millisecond. After i left the race there was no menu clicks. But sound worked fine in windows. Played an MP3 straight after to check that.
I'm not the only one it happend to in the race. This was with the BF1 btw.
I lose the sound from time to time- on 2 or 3 different PC's -- but I always had the same sound card- a Fortissimo III 7.1.. Maybe it is a bug with the way LFS handles that card.. But just do what he said.. shift + w..
