Subject: [PATCH] alsa/usb-audio: Generic DSD detection for Thesycon-based implementations
Date: Mon, 23 Jul 2018 01:56:46 -0700 [thread overview]
Message-ID: <20180723085647.49537-1-yuleopen@gmail.com> (raw)
Thesycon provides solutions to XMOS chips, and has its own device vendor id.
In this patch, we use generic method to detect DSD capability of Thesycon-based UAC2
implementations in order to support a wide range of current and future devices.
The patch will enable the SNDRV_PCM_FMTBIT_DSD_U32_BE bit for the DAC
hence enable native DSD playback up to DSD512 format.
