Problems playing some DSF files
Awesome Donkey:
Are you using DSD bitstreaming or using DSP Studio > Output Format > Output Encoding?
DmitryB:
Awesome Donkey, I'm using this for all playback.
Awesome Donkey:
You're converting everything (PCM and DSD) to DSD which JRiver Media Center does on-the-fly, which is one of if not the most resource intensive operation Media Center can do. It is worth pointing out that all conversions you're doing via Output Formatting are a lossy conversion and not a lossless conversion (and all DSD to DSD conversions you're doing using that setting go through a PCM stage in the middle, so DSD > PCM > DSD). That's likely why you're having hiccups, because MC does the resource intensive conversion on-the-fly it sounds like the system's CPU isn't actually fast enough to keep up with it, so you have issues with clicks, stuttering, etc. This is usually confirmed if lower DSD (e.g. DSD64 aka 1xDSD) works without issues. The higher the level of DSD (especially if it's multichannel) for the Output Formatting conversion, the more CPU/resource intensive it'll be.
If you were bitstreaming DSD files and not converting everything to DSD, you'd probably be fine.
DmitryB:
Awesome Donkey, thanks for that explanation! Do you recommend choosing "None" as the setting? When I have "None," the DSDs are played back as PCMs on my DAC (Teac NT-503).
Awesome Donkey:
Yes, set None for Output Encoding and enable DSD bitstreaming instead. That way DSD files will be sent as-is (with no conversion) to your DAC to decode, and PCM files won't be converted to DSD.
