Trafił do mnie laptop DELL Vostro 3500 płyta LA-K034P z brakiem dźwięku. W urządzeniach nie jest wykrywana karta muzyczna. Układ audio CS42L42 nie grzeje się, napięcia VL_SEL i VP - 3,3V, DIGLDO_PDN - 3V, VL-1,8V, VA-1,8V, pin 2,3-1,8V.
Co mógłbym jeszcze zrobić aby sprawdzić czy to układ czy coś innego, gdzieś czytałem że to może być połączenie pomiędzy procesorem, a układem audio.
