Apple TV AAC/ALAC 7.1 SDDS 2019-12-07 12:21:23 Hello,according to the specification the default channel layout for 7.1 channels in AAC/ALAC is 7.1(wide) or SDDS (L R C LFE BL BR FCL FCR).https://www.iis.fraunhofer.de/content/dam/iis/de/doc/ame/wp/FraunhoferIIS_Application-Bulletin_Fraunhofer-Surround-Codecs.pdfThis layout won‘t get much support on modern devices like my Yamaha Receiver.Does someone know what happens when the audio stream is processed by e.g. my Apple TV?AAC/ALAC 7.1 SDDS (Apple TV) —> PCM 7.1 (L R C LFE BL BR SL SR) (Receiver)OrAAC/ALAC 7.1 SDDS (Apple TV) —> PCM 7.1 SDDS (Receiver) (and Receiver looks for SR and SL so in fact he gets 6 channels)BestFelix Last Edit: 2019-12-07 12:23:20 by FLX90
