Can You Use a USB DAC With PS5 or Switch? Console USB Audio Limits, Explained (with the KEYSION 02 Pro and 01)

Before you blame the cable, know this: the PS5 and the Switch set a hard bar for USB audio. Both only accept UAC1 (USB Audio Class 1.0) devices. A DAC that runs in UAC2 mode, or pushes past 48kHz, usually stays silent. Switch the DAC to a UAC1-compatible mode and pair it with a compliant OTG cable, and most setups come to life.

Why do consoles only accept UAC1?

UAC1 is a driverless standard from 1998 with a practical ceiling around 24bit/96kHz, and real-world links often run at 48kHz. It works on plug-in with no driver install. UAC2 carries more bandwidth, up to 32bit/384kHz and native DSD, but needs a driver or explicit OS support. The Switch keeps USB audio simple, and the PS5 audio stack also calls UAC1. A DAC that defaults to UAC2 simply is not seen by the console's audio stack, so you get nothing.

Who supports what? One table

Console / device	USB audio requirement	Sample-rate ceiling	Mic and voice	What it means for you
Switch (handheld USB-C or dock)	UAC1	48kHz	Playback mainly; voice via controller	The DAC must offer UAC1, or there is no sound
PS5	UAC1	48kHz	Playback only; voice via controller	UAC2-exclusive mode is equally silent
PS4	UAC1	48kHz	Playback only	Close to the PS5 case
Windows PC	UAC1 or UAC2	Driver-dependent, up to 768kHz	Supported	PCs don't care about the mode, so look elsewhere
Android phone	Either, OS-dependent	Commonly 384kHz	Supported	Best compatibility, mostly power-limited

How do I get a dongle DAC working on a console?

1. Switch the DAC to UAC1 mode. Many dongles hide this in a physical switch or an app setting, and ship sitting in UAC2.
2. Use a compliant OTG cable. Consoles are pickier about cable resistance and power delivery; a poor cable's voltage drop can make the DAC drop out right at startup.
3. Watch the power budget. In handheld mode the Switch cannot feed a power-hungry DAC; the dock or a powered hub is steadier.
4. Confirm the console output is set to USB. On the PS5 you pick the output device by hand in Settings, then Sound.

Can the mic and voice chat run through the DAC?

Usually not. Voice chat on the Switch and PS5 runs through the controller or a dedicated headset jack. A USB DAC normally handles playback only. For voice, use the console's own path rather than hoping the dongle's mic input works.

Wired DAC or Bluetooth amp?

Consoles are stricter about Bluetooth audio, and the Switch needs an extra transmitter. A wired USB DAC is usually simpler for latency and stability, as long as the UAC1 mode can be set. For the protocol background, see UAC1 vs UAC2; for cable choice, see how the OTG cable affects power.

A short cable checklist

• Console is a Switch or PS5: the DAC must support UAC1.
• You mostly play handheld: favour a powered setup instead of relying on the console alone.
• You need voice chat: go through the controller and don't depend on the DAC mic.

On the product side, the 02 Pro page and the 01 page state how to switch modes, and the YCX OTG cable is a suitable cable.
