I have no idea what this is about. Your bug report lacks a bug description. There's a bunch of pastes, but these are meaningless without a description.

DSD_U32 applications in the new version does not work! It is a bug! (

MaxKellermann commented 7 years ago

"Does not work" is the worst possible problem description.

norrest commented 7 years ago

This site is not a full-featured bug trackers for internal correspondence of developers, so here you can speak in any form! Does not work - mean "Do not support"

MaxKellermann commented 7 years ago

Your bug report "does not work".

for example: https://patchwork.kernel.org/patch/9479117/ Add DSD support for big endian (DSD_U32_BE)

In my case

/* XMOS based USB DACs /
switch (chip->usb_id) {
case USB_ID(0x27f7, 0x1301): / Wyred DSD Inrerface */
    if (fp->altsetting == 2)
        return SNDRV_PCM_FMTBIT_DSD_U32_BE;
    break;

After this, id dop = off I must see DSD_U32_BE But cat: /proc/asound/card0/* Show Format: S32_LE
