[PATCH 4.19 279/313] ALSA: usb-audio: Add support for new T+A USB DAC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Udo Eberhardt <udo.eberhardt@xxxxxxxxxxx>

commit 3bff2407fbd28fd55ad5b5cccd98fc0c9598f23b upstream.

This patch adds the T+A VID to the generic check in order to enable
native DSD support for T+A devices. This works with the new T+A USB
DAC model SD3100HV and will also work with future devices which
support the XMOS/Thesycon style DSD format.
