I'm having a bit of a problem with using Wasapi in 24 bit with the latest foobar version.
I'm running windows 7 64bit on a newer machine, allocated for music only. 4 GB RAM. I checked latency with the DPC latency tool and it is constant at about 100, so it's really low. Most of my files are FLAC, 60% of them are 16/44 and the rest are native 24/88 and 24/96 from HDTracks. No DSP's are enabled.
There are constant crackles and pop noises when I manually advance from one song to another via the "next" or "back" buttons on foobar, or when a song is in progress and I forward or go back in the seek bar, or when I manually click on a different song while one is playing. It does not happen say if I let the song finish and the next one comes on either in order or in shuffle mode. These pops only occur when I select 24 bit in the Output Format.
When I use 16 bit, the pops are gone completely. I also tried increasing the file buffering to 700,000 to play from RAM but that did not help.
I tried setting the "Fade on seek", "Fade out", and "Fade on pause" all to "0" milliseconds while in 24 bit. This reduced the pops by about 70% when advancing to another song, and it got rid of them completely when moving forward or backward in the song with the seek bar on top.
I understand the general consensus of 16 vs 24 bit not presenting an audible difference. I would still like to solve this problem, if possible. Also, I am not doing any upscaling, just trying to play files at their native resolution.
Thank you in advance for the help!!
