First, I know I tried this a long long time ago… but I just don’t remember if I ever got it to work. Anywho, I am trying again…
Computer w/Foobar direct to DS Senior Windows 10
Foobar works fabulously via USB… plays all 2L Nordic Sound DSD files fine. No issues here. I just select the Device from Foobar “DSD : KS : PS Audio USB Audio 2.0” and it just works… passes the bit-for-bit test fine.
Issue: Hooking up a Toslink optical cable from my sound card to the DS Senior… In Foobar, I select " DS : Digital Audio (S/PDIF) (High Definition Audio Device)"… it works and I get sound to the DS Junior but it will not pass bit-for-bit tests (basic 44/16 WAV and Flac files). Wha happen?
Advice?
In Properties:
I have volume set for 100, Disable all enhancements, Spatial Sound is OFF.
For Advance Tab … should I dick with Default Format? seems odd to select one when my stuff is variable formats
Exclusive mode both at checked.
Supported formats tab is weird… most all are checked.
Reason I am doing this is to break the electrical connection between devices… and see how high my TosLink cable can go. But it won’t pass bit-for-bit test with 44/16 files.
Do you have any DSP configured in foobar2000? Double check that you aren’t sample rate converting (some of the SRCs modify bits even for a 1-1 sample rate change) Check that you don’t have track or album replay gain set.
Also, if the bit perfect test works for a little and then flakes, check the buffering settings in foobar2000.
Some TOSLink hardware/drivers do sample rate conversion no matter how they are configured in the Windows OS.
Perhaps using ASIO instead of kernel streaming might help.
No DSPs nothing that I can see. Again, the USB out is fine and it passes bit-for-bit.
One oddity, is that in the Device panel changes when I select S/PDIF… Output format greys out, and a Fading window comes up … all set to 0 ms.
Asio… ah… where do I get that driver? I use Asio4All for my music instrument and laptop… same one? Or should I get it via Hydrogen? Ah… found it on Foobar2000.org… trying it now.
Ok, installed ASIO component in Foobar… it displays in the Devices, but not for S/PDIF… notes in Foobar components documentation denotes that my card may not support ASIO if it does not show. Odd, it is a popular card. an on-board RealTek in an Asus motherboard… I built this a few years ago.
Sorry I can’t help more. At least in the past some (many?) “motherboard sound cards” always sample rate converted. I don’t know about RealTek. Perhaps a search on the foobar2000 or JRiver forums might mention getting bit perfect playback on your hardware.
