Marantz NA7004 & Hi-Res FLAC

[Rasmussen]

I have an issue which seems to be caused by the interaction between the latest version of MinimServer and my DMR, the Marantz NA7004.

Setup:

- MinimServer v0.8.5.2 update 126
- Windows 7 Enterprise SP1
- Marantz NA7004 (latest firmware)

Problem:

When playing high resolution FLAC files, at the very end of the track, there is a short burst of noise, like a "whoosh" or a fragment of white noise.

Observations:

- This is definitely an artifact. Checked the files w/ an audio editor, and the last few seconds are digital silence.

- It only happens w/ hi-rez FLACs (24/96 and up). It does NOT happen w/ "regular" (16/44.1) FLACs.

- It did NOT happen w/ my previous version of MinimServer (v0.8.4).

- It does NOT happen w/ a different server (Asset UPnP R6.1beta).

- It DOES happen w/ different controllers, including the player's built-in controls.

- It does NOT happen w/ some other players (Shanling DR2.1; various apps on iPad; Kodi on macOS).

Interpretations:

(1) The problem is not caused by controllers.

(2) It is not a simple issue, e.g., "the player is the problem" (no problem w/ Asset or MinimServer 0.8.4); or "the server is the problem" (no problem w/ other players). There must be some interaction between the NA7004's firmware and something new in MinimServer v0.8.5 which causes it.


Any suggestions on how to fix this, or what else to check or test?

Alternatively, any advice about downgrading to MinimServer 0.8.4? (I prefer MinimServer over Asset UPnP.)

TIA.
