Bonjour, depuis hier j’utilise un DAC externe CHORD QUTEST relié en entrée par USB B à mon ordi. (win.10) et en sortie (RCA) à un ampli. Yamaha. La qualité audio est superbe sauf sur les fichiers 24/192kHz : Qobuz) où la bande sonore est parasitée donc impossible à écouter. De plus dans les paramètres d’Audirvana le périphérique audio est bien reconnu (ASIO CHORD 1.05) mais je n’arrive pas à ouvrir la configuration du pilote ASIO. Enfin il est indiqué que le DSD n’est pas supporté alors que le CHORD QUTEST va jusqu’au format DSD512. Merci pour vos éclaircissements!!
P.S.: Autre problème, je suis obligé de désactiver le suréchantillonnage sinon la lecture audio ne démarre pas.
