Description
1.What's Android USB type-C audio?
There are two ways to send audio data through the USB type-C port - Analog and Digital. Analog audio can be converted with an onboard DAC and amplifier inside your phone then sent out through the port to a passive set of headphones or an adapter. For this to work, the device needs to support whats called "audio accessory mode" and the headphones or adapter are just "dumb" connections that pass along the signal.
If you are using an active set of headphones or adapter, the audio signal being sent through the USB port is still in its digital form. That means the DAC and amplifier are inside of the headphones or the dongle, and the conversion is done there instead of the phone.
This can get messy. You need to make sure that you're using the right "thing". If you are using a passive adapter or headphones, your phone needs to support audio accessory mode and many don't. The mess is because most dongles, adapters, and headphones aren't labeled with how they are built and we don't know if they are active or passive.
2.How to check the USB type-C audio?
There is a one-key widget to show your headphones working in digital or not.
3.How to use USB Audio Checker?
It's very easy , click "Check USB Audio" after connecting your headphones or adapter.

Simple does what it's supposed too. Let the person get their few bits of ad rev for such a simple app and stop complaining. It's just here to answer a question the companies are making unnecessarily complicated to answer.

It surprised the heck out of me that the app actually worked
★★★★★Redeemed Pinoy· Feb 23, 2023
This app is able to detect if my Redmi Note 9s can support usb type c to 3.5 mm adapter. It says that this phone cannot detect the earphone plugged through this adapter.

What a useless app is this. Just Says Using USB audio. No other info about The Connected DAC. It's a shame 👎

It can identify partially, there is no provision to know capabilities of usb c dac like bit rate, sampling frequencies. However, capabilities can be seen in Onkyo HF Player.

Awful. Too many ads on main menu, click on anything you'll get ads.
