Cannot hear others cars engines around me in the game (Mine is perfect)

HEllo Everyone,

Bug Info: When racing or free roam I cannot hear the other cars engines surrounding me . I made a video from the xbox gamebar Afficher la capture |  Xbox
I listened from other PC , and the issue is present , so it’s not a matter of speakers setup.
So it’s really a matter of internal sound processing
I can hear my engine really perfectly , loud and clear. I can hear all the others noises : horns from other cars , train, rain, wind, dogs , birds … )
Platform: Steam
Edition: Deluxe
Account: solo account
PC GPU: RTX 4070 with latest drivers
Peripheral: SoundBlaster AE-5+ with Logitech Z623 (2.1 kit)
Settings: Stereo mode 16 bit 44/ KHz.

Attempted fixes: tried 24 bit /96KHz too . tick / untick broadband speakers in windows and the SB command software . I set the engine noise at level 100, lowered all the other ones , especially tyres for example.
Content Update: really dunno : i keep Windows and my drivers up to date. I think it was okay just after I made a fresh install of my PC .

Please , can someone help ???
