leadtek winfast 2000 - spatny zvuk

Ahoj lidi, asi uz jste pro me posledni zachrana, mam problemy se zvukem na teto karte. Obraz jde dobre, ovsem misto zvuku slysim jakesi divne chrceni mezi kterym misty zaslechnu zvuk z tv, zkousel sem celou radu nastaveni modulu bttv konkretne tuneru(asi 15 cisel, nemuzu ted najit svoje poznamky ale urcite sem zkousel tuner=38,24,5 a dalsi), obraz ziskam jen na par z nich ovsem vsechny maji stejny problem se zvukem. Pouzivam program Tvtime, pokud menim zvukovou normu primo v programu tak to nema na vyslednem zvuku naprosto zadny efekt, chytam(analog signal) na celkem spatnou antenu ale win mi jede zvuk naprosto krasne. Nevim ted presne v cem spociva problem, pokud je to v nastaveni ovladace, v nastaveni tvtime, nebo v necem uplne jinem.
