[PROBLEM] DSD1024 support

[TheOldPresbyope]

@Tim Curtis

<tl;dr> I got a similar mediainfo report for the one DSD1024 track I could find yesterday. It also doesn't play.

I went web surfing last night and was able to come up with only one DSD1024 track that was free to download. Have a look at Wechseldominante, who describe themselves as a Japanese self-publishing music group.

There's a number of tracks ranging from DSD64 to only one DSD1024. The latter has been upsampled but they don't say from what.

Anyway I downloaded its 2+GB zip file as well as several files at lower resolution.

All the lower resolution files "play" in the sense that moOde/MPD don't throw throw errors (my DAC craps out at DSD256). They all have similar mediainfo reports. Example (I renamed the downloaded file):

Code:

OTOH, attempting to play the single DSD1024 track triggers the MPD error

Code:

Failed to open "ALSA Default" (alsa); Error opening ALSA device "_audioout"; snd_pcm_hw_params() failed: Invalid argument

For this track, mediainfo reports

Clearly the DSD1024 track was authored by different software and I have no way to check or validate its structure but it's telling that this is the same kind of mediainfo report shown by the OP.
