Feature description:

Hello,
I really like Symphonium’s UI and overall experience.
I’m using an external USB DAC (FiiO KA17), and one feature that would greatly improve the app for advanced users would be true USB exclusive / bit-perfect playback with automatic sample rate switching, similar to what USB Audio Player Pro does.
At the moment, the DAC doesn’t always receive the native sample rate of the audio file, which limits the potential of high-quality external DACs.

Problem solved:

Adding optional bit-perfect mode would make Symphonium a top-tier player for audiophile and professional users.
Thanks for your great work.

Brought benefits:

Good afternoon. First of all, I also want to join in the congratulations because this is an incredible app. I’ve encountered a similar problem when trying to play bit-perfect music. I’m using a Motorola G84 5G phone with Android 15, connected to a FiiO KA15 USB DAC. When I play files (from my NAS) at 96 or 192 kHz, the FiiO correctly displays those values ​​on its screen. But when I play files at 44.1 kHz, it displays “48K,” so I assume they aren’t being sent directly to the FiiO, but rather that Android is oversampling. Is there currently a way to fix this so that the DAC receives the exact original quality of the files that Symfonium plays?
I congratulate the developer again and hope for a prompt response.
