Isso me ajudou muito com o driver da Crap HP.
- Instale o driver mais recente, que é o Audio IDT 6.10.6491.0 2015/09 sp63555.exe
- Aplicar caminho reg para desativar os "aprimoramentos".
- Restaurar o tom de graves / agudos a 0 no painel de controle de áudio padrão do Windows.
Depois de muitas tentativas, Finnaly um bom áudio!
