Vi segnalo queste due schede che ho provato e le ritengo valide per la creazione di sistemi di riproduzione Wireless

Video Recensione e test dei ricevitori audio wireless Aclyric, modello Up2stream Mini e Up2stream Pro, gestibili con la App 4STREAM. Sono gli oggetti adatti per costruirsi il proprio BoomBox o impianto di riproduzione audio di casa, con accesso alla musica web e agli storage di casa. Le schede offrono l'uscita analogica e digitale con standard i2s e spdif e sono compatibili con i protocolli più diffusi come DLNA, Spotify Connect, Qplay, UPnP e decodificano tutti i formati audio tra i quali FLAC, MP3, AAC, AAC+, ALAC, APE, WAV
