Hi @Mao-Hsien_Wang ----- Thank you for following up with me and providing the requested feedback. Both are very appreciated!
Moving forward, when hearing a “hiss” sound during playing back of DSD content is the result of a device playing back a “DSD over PCM” stream as if it were PCM. Can you verify for me if in your “device setup” window you have “DSD Playback Strategy” set to “Native” (example below) and furthermore, it looks like you are making use of the DSP engine. Can you also confirm that under “sample rate conversion” that the conversion is set to “DSD” and “enable native DSD processing” is set to “yes” (example below)?
