Drop down the menu and manually change it to 32-bit, 384000 Hz (Studio Quality) .
Use a TCXO (SiT1552) if you need low phase noise for 384kHz playback. The is a popular high-resolution USB-C DAC/Amp chip
If you are building or modding a CX31993 board, inspect the decoupling capacitors. The datasheet recommends placing 0.1µF and 10µF ceramic capacitors as close to the VDD pins as possible to filter high-frequency noise. Adding an external ferrite bead to the USB VBUS line drastically cuts down computer switching noise.
The has quickly established itself as the go-to chipset for ultra-budget, high-resolution USB-C DAC dongles. Offering a staggering 32-bit/384kHz PCM sampling rate and a theoretical signal-to-noise ratio ( SNR) exceeding 128dB , this tiny integrated circuit outperforms standard motherboard and smartphone audio outputs by a wide margin.
