    Hi,
    I have a Bluetooth 5.0 recever that supports aptX[e]2122[/e] HD (48khz and 24Bit), I'm using my OnePlus 5T to stream music to my stereo system and unfortunately my op5t supports only 16bit and 44.1khz while on other devices which is not OnePlus supports 48khz (I'm not sure how many bits 16 or 24).

    is there any idea?

    thank you!

    Usually phone will identify connected Bluetooth device's capability and use appropriate codec, but if that isn't happening in your case, you can go to Settings > Developer Options and manually change Bluetooth Audio Codec to aptX HD

    a few questions.

    -do you have music files in 24bit?
    -does your sound system which connects to your receiver support 24bit (if it connects digitaly) and 48kHz?

    576 kbit (which should be the bitrate of aptx hd) may sound better with 16bit audio.

    44.1 vs 48 will not sound any different. It will use whichever rate the original audio was recorded in. Otherwise, it would have to resample the audio which wastes CPU power and can cause distortions

    Your device is working fine. Why are you trying to force 48Khz? If the audio was ripped from a CD, then 44.1 is correct, not 48

    You can't get a better bit depth than the original recording

    In developers menu, 3 below that Bluetooth codec option, you can force 16,24 or 32 bits... don't know if it helps

    thats right, but there are ways to listen to music with 24bits eg with tidal masters. (only via pc)

    Yes, but some people seem to think that trying to play 16 bit audio at 24 (or higher sampling rates) will magically make it sound better. The won't waste time or bandwidth trying to upscale the data.

    the thing is there was never a problem with bit dephs or sample rate. 16bit and 44.1khz is just perfect. only bitrate eg with low quality mp3 can bottleneck quality.

    if one wants better sound he should go with new amplifiers and speakers.

    You do realize that Bluetooth is low bandwith and can't support data rates that high? Also, ALL bluetooth audio uses lossy compression.

    32bit is pretty much overkill since human sensitivity is around 20 bits. 384Khz?? 192 isn't enough?

    Do want high quality? Then why use lossy compression?? Get a freaking wire. Bluetooth isn't designed for that.

    However, check out AirAudio (WiFi).

    It's just that I'm too lazy to convert it

    aptX[e]2122[/e] HD was designed to play music up to 24bit and 48khz, which is indistinguishable from hi-resolution audio.
    I have a music (FLAC) with hi resolution audio and when I am playing it on my device the protocol makes downscaling...

    I think that the OS on the OnePlus 5T makes it happen.
    when im forcing the right bits and khz in the "developer options" nothing was changed.
