6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Max McCarthy <mmccarthy@xxxxxxxxxxxxxxxx> commit 99248c8902f505ec064cf2b0f74629016f2f4c82 upstream. McIntosh devices supporting native DSD require the feature to be explicitly exposed. Add a flag that fixes an issue where DSD audio was defaulting to DSD over PCM instead of delivering raw DSD data.
