Subject: [PATCH] sound: add quirk flag to enable native DSD for McIntosh devices
Date: Tue, 24 Oct 2023 12:30:19 +0000	[thread overview]
Message-ID: <BL0PR13MB4433226005162D186A8DFF4AD6DFA@BL0PR13MB4433.namprd13.prod.outlook.com> (raw)

From: Max McCarthy <mmccarthy@mcintoshlabs.com>

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.
