Manufacturer	Model	Connection	Detection	PCM	DSD	Volume	Status	Notes
Allen & Heath	Xone:96 (USB 1 port)	USB (UAC2)	USB 22f0:001a	44.1–96 kHz, 32 bit	none	software	Reported	USB soundcard of a DJ mixer: it takes 12 channels only (S16_LE or S32_LE, no DSD). bitwerk plays stereo bit-perfect on USB channels 1/2 and silence on the others; select USB on the mixer channel that receives USB 1/2. No hardware volume: leave the player at 100 % to stay bit-perfect and set the level with the mixer’s channel fader.

Allo	Boss DAC	I²S HAT	allo-boss-dac-pcm512x-audio	44.1–192 kHz, 24 bit	none	hardware (Digital)	Documented
Allo	Boss2	I²S HAT	allo-boss2-dac-audio	44.1–192 kHz, 24 bit	none	software	Documented
Allo	DigiOne / DigiOne Signature	S/PDIF HAT	allo-digione	44.1–192 kHz, 24 bit	dop	software	Documented	DoP over S/PDIF only works if the downstream DAC recognizes DoP; with a 176.4 kHz carrier, DSD64 is the maximum.
Allo	Katana	I²S HAT	allo-katana-dac-audio	44.1–384 kHz, 32 bit	dop	software	Documented	Whether DoP or native DSD works depends on the driver version: if aplay --dump-hw-params lists DSD_U32_BE, use HIFI_DSD=native.
Allo	Piano 2.1	I²S HAT	allo-piano-dac-plus-pcm512x-audio	44.1–192 kHz, 24 bit	none	hardware (Digital)	Documented
Audiophonics	I-Sabre ES9038Q2M / ES9028Q2M (incl. Kali Edition)	I²S HAT	i-sabre-q2m	44.1–384 kHz, 32 bit	dop	software	Documented	The card ID is the generic DAC, so bitwerk recognizes the board by its overlay in config.txt. Use hw:CARD=DAC,DEV=0 unless another card is also called DAC. DSD travels as DoP (DSD64 at 176.4 kHz, DSD128 at 352.8 kHz). The I-Sabre driver has its own digital volume; until it is tested, keep bitwerk on software volume at 100 % or fixed volume to stay bit-perfect.
Audiophonics	I2S DAC (ES9023 / TDA1387)	I²S HAT	hifiberry-dac	44.1–192 kHz, 24 bit	none	software	Documented	Same overlay and codec as the HiFiBerry DAC+ Light, so the player cannot tell them apart: it shows I2S DAC (PCM5102A); give it its own name in the web UI (Settings → Player → Output). No hardware mixer: software volume at 100 % or fixed volume stays bit-perfect.
HiFiBerry	Amp4 / Amp4 Pro	I²S HAT	hifiberry-amp4pro	44.1–192 kHz, 24 bit	none	software	Documented	Recognized by its TAS5754M codec (tas5754m in the card’s PCM name, overlay hifiberry-amp4pro). An Amp4 loaded with hifiberry-dacplus-std reports the PCM512x codec of the DAC+ and shows up as a DAC+; give it its own name in the web UI (Settings → Player → Output).
HiFiBerry	DAC+ HD	I²S HAT	hifiberry-dacplushd	44.1–192 kHz, 24 bit	none	software	Documented	Also the DAC2 HD: same overlay, card and codec, so it shows up as DAC+ HD; give it its own name in the web UI (Settings → Player → Output).
HiFiBerry	DAC+ Light / DAC+ Zero / MiniAmp	I²S HAT	hifiberry-dac	44.1–192 kHz, 24 bit	none	software	Documented	Other boards without a control interface load the same overlay and report the same codec (Audiophonics ES9023/TDA1387 boards, many PCM5102A boards), so the player cannot tell them apart: it shows I2S DAC (PCM5102A); give it its own name in the web UI (Settings → Player → Output). No hardware mixer: software volume at 100 % or fixed volume stays bit-perfect.
HiFiBerry	DAC+ Standard / DAC+ Pro / DAC2 Pro / Amp2	I²S HAT	hifiberry-dacplus, hifiberry-dacplus-std, hifiberry-dacplus-pro	44.1–192 kHz, 24 bit	none	hardware (Digital)	Documented
HiFiBerry	Digi+ / Digi2 Pro	S/PDIF HAT	hifiberry-digi, hifiberry-digi-pro	44.1–192 kHz, 24 bit	dop	software	Documented	S/PDIF output without a volume mixer. DoP only works if the downstream DAC recognizes DoP; with a 176.4 kHz carrier, DSD64 is the maximum.
Raspberry Pi	DAC Pro	I²S HAT	rpi-dacpro	44.1–192 kHz, 24 bit	none	software	Documented
Raspberry Pi	DAC+ / IQaudIO DAC+	I²S HAT	rpi-dacplus, iqaudio-dacplus	44.1–192 kHz, 24 bit	none	hardware (Digital)	Documented	Also matches the IQaudIO DigiAMP+ on older images, which load iqaudio-dacplus,unmute_amp.
Raspberry Pi	DigiAMP+	I²S HAT	rpi-digiampplus	44.1–192 kHz, 24 bit	none	software	Documented	Load the overlay with unmute_amp: dtoverlay=rpi-digiampplus,unmute_amp.

Status: Verified = tested on maintainer hardware at every release. Community = at least two independent reports. Reported = one report. Documented = taken from the manufacturer documentation, not yet tested with bitwerk. Known problems = works only with restrictions, see notes.

Request support

Not listed, or not bit-perfect? Run the DAC report on the player and send it to us; it works without a GitHub account. The report lists what the DAC offers (USB ID, formats, rates, mixers) and holds no serial numbers, host names or network addresses. If your DAC works, the same report helps it become a “Community” entry.

hifi-client --mode dac-report --json

What do you want to tell us?

My DAC is missing or does not play bit-perfect My DAC works (or works with limitations)

Manufacturer and model Output of hifi-client --mode dac-report --json What did you try, what happened? (optional)

Open email Use the GitHub form instead

The report holds no serial numbers, host names or network addresses. Nothing is sent until you send the email yourself. With a GitHub account: request support or report a DAC.
