Hi folks, I am new here, but not really new to Roon or HQP. I am faced with the following.
Even with “Adaptive sample rate” enabled/greyed (semi-enabled) and also forcing 44.1K sources to only integer multiples of it, I am hearing white noise behind the music (actually like 60% static noise and 40% music). The path is like this: Roon (44.1KHz) → Roon → Holo Red streamer → Holo Spring 3 KTE DAC (screenshot below). There is no issue with 48K (or 96K i.e., multiples of 48K) music files here. Only with 44.1 and its multiples does Sinc-L behave like this. I diagnosed the sample rates on the DAC screen, and everything “theoretically” is working fine except for the sound when using SINC-L. Computation power is not an issue - no stuttering.
Can anyone please make some suggestions? [some screenshots given below - the problematic case - if changed to 48K or multiple - all fine!]
Just as a background, some time ago I reached out to Jussi (I really do not know his username on the forum) and he mentioned the following via email but it is not working for me and I moved on and now back to figuring this out. Context as follows:
Hello,
sinc-L cannot convert between rate families, like from 44.1k to 1.536M, only integer factors. While most poly-sinc group of filters can do such conversion (these are recommended anyway). HQPlayer shouldn’t allow such cases to start playing in first place. Please let me know what HQPlayer says about it’s output format in such case.
In HQPlayer, use the “Adaptive output rate” as checked of grayed. In checked setting it always keeps integer factor, while in grayed setting it uses integer factor only when the filter requires it. When it is unchecked, the set output rate is explicit request. In other cases set output rate is highest allowed, but lower one can be selected when necessary.
Best regards
Will really appreciate any help.
Thanks.
. Please suggest if you think something that can fix this. I am using PCM no DSD. Appreciate it.
