Swiching to 48kHz while using aptx

I am using samsung galaxy s10 and it supports aptx. I bought an wireless earbuds that support aptx too. I switched to Hi-res output, with 48kHz, 16bit. However, when i play an audio of 48khz, 24bit, the aptx output of my earbuds is only 44.1kHz, 16bit. Doesnt aptx support 48kHz, 16 bit? Is there a bug? I would be grateful if you can help me.

You could try turning DVC off (or on), but it could also be a limitation of the Samsung driver. Most Samsung devices don't support 24-bit output below 192kHz anyway.

@andrewilley thanks for your reply.

But actually my focus was on the sampling rate instead of the bit depth. Aptx supports 48 kHz, but when I played a 48kHz audio, it downsampled to 44.1kHz. I also tried turning on and off the DVC but this does not work for me

Have you tried different Output modes in AP Settings > Audio > Output. Could just be a Samsung limitation though (for example on normal modes, even if you have a 44.1k file Samsungs would default to 48k final output anyway). @maxmp might be able to advise further.

@andrewilley thank you Andre.

I have just found out that it is Samsung's problem. It only allows me to switch to 44.1kHz for Bluetooth (even for aptx codec). I don't know if this only happens to me and maybe I will ask in the Samsung forum
