I’m trying the demo version of Audirvana (3570) on a MacBook-pro with the latest version of Catalina (10.15.7), and the Mac is connected using a USB-C to HDMI câble to an ARCAM AVR-750 receiver.
I have no problem playing multichannel audio tracks. The receiver usually gets PCM 7.1 176.4 or 192KHz.
However, when I’m playing a stereo track, no matter what I do, Audirvana doesn’t switch the output to PCM 2.0, and always uses PCM 7.1
–> This is a problem for me as the ARCAM receiver has many STEREO features that I cannot activate, as the receiver is receiving multichannel audio.
I tried to activate the FORCE STEREO switch in Audirvana output configuration but that didn’t work. (Even after a restart of Audirvana or a Mac reboot).
I tried to run macOS MIDI setup, select a 2-channel mode, reboot the Mac… etc… but as soon as I play a track from Audirvana, I can see the MIDI config switching to 8 channel 176.4 KHz again.
Compared to the same tracks played from my Oppo BDP-95 Universal Blu-ray player:
- When playing a multichannel track, the receiver gets PCM 5.1
- When playing a stereo track, the receiver gets PCM 2.0
Could you please advise ? I would like Audirvana to behave the same as the blu-ray player, and output multichannel for multichannel tracks, and PCM 2.0 for stereo tracks.
Is this possible ?
