On Foobar 09.4.2 with SRC at 176, wavs play fine and so do Apple lossless files. But Flac files don't play without stuttering. WOrks on KS and DS outputs. Asio 4 all stutters no matter what.

Here is a video of the behavior:

Flac works fine at 96, but not at 176.

Any ideas why ALAC and wav work fine, but flac doesn't?

TIA
