Mac OS: DSD playback to Chord Hugo TT goes silent [Solved]

(1/3) > >>

cantara256:
I've been using MC for a year or so no without no problems at all. I have my first DSD files to try out and after playing for a minute or two the output goes silent and stays that way until I either restart, stop/start playback again, or play another file type.

These same files play just fine on my Astell & Kern AK380.

I've tried:

* Bitstreaming none or DSD
* Output encoding DSD in DoP format or none
* Audio MIDI Setup for Hugo TT to 384 kHz but always goes to 176 kHz when MC is runningAlways goes silent around 1:50 into any track, though MC shows the track is still playing, even the equalizer is doing its thing like normal. But no sound unless I restart/stop & play again/switch to a different audio format track and then back to DSD.

Any ideas? Thanks,

Raul

Awesome Donkey:
How are you playing back your DSD files? Locally or from a NAS or something like that? Are you using any of the memory playback features?

If you're playing back DSD64 files, this is normal for DoP (which is the only way to playback DSD on Mac).

cantara256:
All files are local. I'm not aware of the memory playback features and haven't played around with any of that.

cantara256:
What are the ideal settings? Betwenn the wiki on DSD, the various posts I found, and what the current setting options are I'm not sure:

* Audio Device set to is HugoTT (Core Audio). What about integer mode and buffering (software/hardware at recommended 100ms/Hardware default)?
* Output Format: Sounds like Output Encoding should be DSD in DoP
* Bitstreaming: HDMI, S/PDIF, DSD or none?Files are: DSD64, 1 bit, 2.8224 Mhz, 5.6 Mbps, 1 Area (stereo). Confirmed memory playback is disabled.

All output goes silent at exactly 1:52, for any DSD track. This happens even if I disable bitstreaming and set output encoding none. So weird.

Awesome Donkey:
Unless you want to purposely convert everything (e.g. PCM) to DSD, I wouldn't mess with Output Format at all, just enable and use DSD bitstreaming for DSD files. Also integer mode and buffering settings won't matter much.

It's a strange issue, but you might want to see if the files themselves are "good" and not somehow corrupt. You could also try disabling DSD bitstreaming (and not use any Output Format settings) and see if the files play fully when MC converts DSD to PCM on-the-fly to rule out the possibility of bad files.
