What is the processing speed indicated in the audio signal path? If less than about 1.3x then your processor is maybe not quite enough.

Hi @wizardofoz

It does not show the speed. Maybe it do not show the speed in the DoP playback mode ?

Can you screen shot the audio signal path here please. And the audio settings screen too perhaps.

Hi @Chorus_Chuang,

Does this occur with all DSD64 content?

If you configure another endpoint to play the same content does the same behavior occur?

Hi @dylan,

I am sorry I do not have “all” DSD64 content and it is not possible for me to test “all” DSD64 content.
In my test, there are 10 DSD64 music in this album have this situation.
Or maybe you can send me your DSD64 music so that I can test for you.

And could you tell me more about “another endpoint to play the same content” ?
Thank you!

Best regards,

Hi @dylan,

Today I test again with the same setup (also the test file) and the problem is gone.
Please ignore this and I will check the environment again.

Thank you!

Best regards,
