Fiio KA17 and music kHz

Issue description:

Hi, firstly: congratulations on the amazing app you have developed, and secondly: I don’t know if this is a bug or a feature.

I’m using dropbox with a Poco F7 Pro and a Fiio KA17 DAC and on the DAC display, 44kHz songs show 48kHz, 96kHz songs show 192kHz.

The curious thing is that, after listening to a song at 96kHz, the DAC continues to show 192 for all songs regardless of the frequency.

I notice that if I wait about 3 seconds after the 96 song finishes and a 48 song starts, it shows it correctly, but if played in sequence, especially on the skip button, everything stays at 192kHz.

Is this to be expected?

Thanks and best regards.

Depends on many things on OEM devices.

You can try to disable prefer Internal decoder, to enable hi res, to enable offload and see if any combination fixes the DAC display.

Thanks for replying, I did and nothing changed, but no problem, I only reported it because maybe it was something important, but if it’s normal that’s fine.

In your opinion, does enabling the offload, even with a DAC, help the sound quality?

Sound quality is very subjective :slight_smile: As soon as you enable EQ or anything on the pipeline you are not bit perfect. And it most of the time sounds better with EQ due to the headphones. (Unless you have ones at 10K€ ;))

Offload can reduce battery usage, but can generate a lot more issue with some file format.

Hello, I’m going to revive this topic with a simple question: is there a way to enable upsampling to 192 or 384 kHz? For those who use an external DAC, this would be great because I’ve done extensive testing and, at least on the FiiO KA17, upscaling improves the sound, perhaps due to some limitation of Android 15. I have all the equalizers turned off, including the DAC.

Thank you, Tolriq, for the app, the support, and your patience in helping us.

Regards.

No plans for that, quality upsampling is the job of the DAC.

No problem, I learned a trick: I start any song at 24/96 and Android sends 192 kHz to the DAC, after that, everything I play stays at 192 until I exit the app and open it again :sweat_smile:

The DAC is doing some strange stuff you can see Symfonium logs to check at what sample rate Symfonium and Android does output.

Hello, I discovered what is happening: Android does not recognize anything above 48 kHz, which causes all this confusion. I set Symfonium to 48 kHz and everything worked. I tested DAC on the iPhone 16e and it works as expected at all frequencies, but the sound was strange, perhaps because of the app.

The question remains: is there currently any Hi-Res Android device capable of going beyond 48 kHz?

Cheers

Again check the logs. If Symfonium outputs at more than 48Khz then it’s your device saying it does support that and so your issue is something else.

Most recent Android devices supports up to 192Khz.
