I am having problems playing dff files with MC17.  I am using the Centrance driver with an all digital system 24/192.  Is there a recommended debugging process?  I tried different drivers an get skipping on all of them.  Thanks.

You need a pretty fast computer to do DFF @ 192 kHz.

What is your JRMark (Help > Benchmark)?

What happens if you pick 88.2 kHz in DSP Studio > Output Format?

Finally, make sure memory playback is turned off (Options > Audio).

JR Mark version 17.0.68:532

It worked fine without skipping at 88.2, when I set it to 96, it starts skipping.  Any reccomendations?  I really want to play this music at 24/192 if possible.  It is currently running on an intel atom based tix motherboard (Computer Audiohile Pocket Server 2.0).  Should I upgrade the motherboard?  Does MC use multi threading and multi core machines?

Thanks,
Bob

Yep.  That's probably not going to do it.

Mine's 3138, and that was run while SageTV was actively recording something and with Firefox open with like 15 tabs.

Heavily.

Unfortunately I think you may just be asking too much from an Atom.

Does playing a WAV, FLAC, or APE at 192 kHz work (using DSP Studio > Output Format)?

Playing wav and flac at 24/192 is fine.  I have wav files digitized from LP records and 24/192 files from HD tracks.  I guess I could try to find a program to translate .dff to flac?

What specs would I need for a motherboard to handle this (playing dff files at 24/192) with MC?  I wanted a fanless mb which is why I went with the CA recomendation.  Thanks.

Wow!  What kind of machine gives you those performance numbers?

I don't think it is a hardware issue because I have buffering set to maximum and after the buffer period it starts to play only for a few seconds and then stutters (shouldn't it play correctly for the entire buffer period of 20 seconds?).  I tried Foobar 2000 on the same hardware and it is not having these problems with diff files.  It also seems strange that these files play fine at 88.2 but play very badly at 96.

[update] i was mistakenly playing aiff files.  All diff files i am trying skip at all resolutions i try in MC 17.  Even 44.1.  Something else must be wrong - any suggestions?

It isn't even that new.

It is a Core i5 750 (Lynnfield, not Sandy Bridge) at just under 4.0GHz with 16GB of RAM.

DSD (and DSD 2x) is working here.

Even downsampling to 48 kHz, mixing to JRSS 5.1, and encoding as Dolby Digital for S/PDIF output, I'm only seeing about 1% CPU usage with 2.8 MHz DSD (1x).

Could I have my settings wrong?  I ran Foobar all afternoon on diff files with output at 24/192 and no problems.  Bummer because I really like MC

Could it be driver related?  I've run profiling software before where CPU usage by windows process is tracked.  Is there an instrumented or debug version of MC17 I could run to identify the problem?

[added] To reiterate, Foobar 2000 with the DIFF plug in added plays at 24/192 without a hitch.

Thanks

Any suggestions on how to resolve this?  I don't think it's hardware related since Foobar plays the diffs fine.  Thanks.  Btw ... Is there support directly fro JR ( I am a new customer).
