Folosești conexiunea HDMI sau Jack pentru sunet?

conexiunea jack. m-am lasat pagubas. nici nu prea ma pricep, asa ca la vizionat filme si ascultat muzica poposesc pe w7.

E placă de sunet Azalia, ca și a mea. Mergi la Administrare, Administrator actualizări, Editare, Preferințe și activează toate tipurile de actualizări până la nivelul 5. Pe urmă actualizează sistemul. După aia dai restart și ar trebui să meargă.
