Thanks.

I'm not familiar with your conventions, sorry for any inconvenience.
The general rule for submitting a kernel patch is well described in
Documentation/process/submitting-patches.rst.

Hi all,

This is a patch for sound/usb/quirks.c which enables DSD support for a
new T+A DAC for which we have developed the USB firmware. Here is a
patch description:

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.


I hope you can apply this patch. Let me know if you need more info.
Could you give your sign-off (Signed-off-by: xxx line) at least?
This is mandatory for merging to the upstream.  I should have
mentioned that in the previous conversation...


thanks,

Takashi

Thank you,
Udo
