Subject: [PATCH] ALSA: usb-audio: Add DSD support for Comtrue USB Audio device
Date: Thu, 31 Jul 2025 19:06:14 +0800 [thread overview]
Message-ID: <20250731110614.4070-1-noble228@gmail.com> (raw)
From: "noble.yang" <noble.yang@comtrue-inc.com>
The vendor Comtrue Inc. (0x2fc6) produces USB audio chipsets like
the CT7601 which are capable of Native DSD playback.
This patch adds QUIRK_FLAG_DSD_RAW for Comtrue (VID 0x2fc6), which enables
native DSD playback (DSD_U32_LE) on their USB Audio device. This has been
verified under Ubuntu 25.04 with JRiver.
