Scheda audio esterna 5.1

Ciao a tutti,

vorrei comprare su eBay una scheda audio con uscita digitale (SPDIF), mi serve per collegare il notebook all'amplificatore Yamaha DTS/DD5.1 tramite cavo ottico e ovviamente veicolare la traccia AC3 in modo corretto.

Secondo voi questa scheda (o qualcuno l'ha provata) veicola l'audio 5.1 AC3/DTS tramite uscita ottica? Oppure solo 2 Canali?
Dalla descrizione non si capisce bene, sembra veicoli solo 2 canali del PCM 5.1 .....ma DD/DTS dovrebbero passare in 5.1 ?
