Aide son

Bonjour, j'ai formaté mon pc mais à la fin aucun son de plus j'ai instalé un pilote diffirent de celui de macarte son, tandis que le mien est alcxwdm.sys version 5.10.03640 de la carte son realtek ac' 97 audio. J'ai cherché ce pilote partout sns aucun résultat sachant que le test que j'ai fait pour le son a aboutit au résultat suivant:
Sound Tab 1: DirectSound test results: Failure at step 19 (User verification of software): HRESULT = 0x00000000 (error code)
Sound Tab 2: The file blueletaudio.sys is not digitally signed, which means that it has not been tested by Microsoft's Windows Hardware Quality Labs (WHQL). You may be able to get a WHQL logo'd driver from the hardware manufacturer. DirectSound test results: Failure at step 19 (User verification of software): HRESULT = 0x00000000 (error code)
