Topic: Linux / Manjaro & MacOS Catalina: 0 bit tests passing

Linux Setup:
==

Linux 5.4.97-1-MANJARO
Using VLC (3.0.12) for bit test playback. Directly wiring in (USB -> ADi-2 DAC fb)
$> lsbusb
Bus 001 Device 013: ID 2a39:3fd3 RME ADI-2 DAC (59920649)

Mac Setup:
==

Catalina 10.15.7
Playing through Music App


Sound is output & cleanly audible, would like to get bit tests to pass. Any calibration ideas or additional information I can provide?

Re: Linux / Manjaro & MacOS Catalina: 0 bit tests passing

Is volume at 0dB (check music player and any mixer devices).

Yes, it is.

Re: Linux / Manjaro & MacOS Catalina: 0 bit tests passing

Sorry no further idea.

What interface is VLC using?
ALSA? Jackd? Portaudio?

No comments for VLC on Linux

Music on Catalina should play bit perfect. Check: 1) Volume at 100% (done), 2) Uncheck "Sound Check" in Music>Preferences>Playback, 3) Set the correct bitrate/bit depth for your test file in the "Audio MIDI Setup" app (located in User/Applications/Utilities). these steps should do it.

Re: Linux / Manjaro & MacOS Catalina: 0 bit tests passing

Music on Linux and Mac should play bit perfect. software such as MPD gives you 32bit of accuracy on Linux (via ALSA) and 24 bit accuracy on Mac (via CoreAudio). If not, your setup is wrong.

Re: Linux / Manjaro & MacOS Catalina: 0 bit tests passing

On my Mac, to pass the Bit Test with VLC I must set "resampling" to "Off" in the advanced settings of VLC. smile
