Re: [PATCH] ALSA: usb-audio: Add Hiby R3 to quirks for native DSD support
+ /* ESS Sabre based USB DACs */ + case USB_ID(0xc502, 0x0051): /* Hiby R3 */ + if (fp->altsetting == 4) + return SNDRV_PCM_FMTBIT_DSD_U32_BE; + break; Do you know who's vendor id is this? ESS Sabre is a DAC chip with I2S input, I'm not aware of any product from ESS under Sabre brand that would include USB interface. (?) So likely the USB interface is sourced from somewhere else... It is good to check with "lsusb -vvv" if the device flags DSD altsetting as raw. Then you know it'll work with the auto-detection code and doesn't break so easily if firmware update changes altsettings (not uncommon to happen). - Jussi

IOW, instead of adding an individual entry here, adding the vendor 0xc502 with fp->dsd_raw check like below would work? thanks, Takashi --- a/sound/usb/quirks.c +++ b/sound/usb/quirks.c @@ -1658,6 +1658,7 @@ u64 snd_usb_interface_dsd_format_quirks(struct snd_usb_audio *chip, case 0x152a: /* Thesycon devices */ case 0x25ce: /* Mytek devices */ case 0x2ab6: /* T+A devices */ + case 0xc502: /* ESS Sabre */ if (fp->dsd_raw) return SNDRV_PCM_FMTBIT_DSD_U32_BE; break;
