If anyone has any objections, please let me know. ------------------ From: Phil Willoughby [ Upstream commit bc5b4e5ae1a67700a618328217b6a3bd0f296e97 ] The NeuralDSP Quad Cortex does not support DSD playback. We need this product-specific entry with zero quirks because otherwise it falls through to the vendor-specific entry which marks it as supporting DSD playback.
