Oh ok so Everytime I turn off the es100, it would reset the sample rate back to 44.1k, and I would have to set it back to 96k when I turn the es100 back on? I'm wondering if this is not al behaviour, I was under the impression that the dev options would only reset upon reboot of the phone.
This is the same whit all bluetooth adapters i have i think the problem is on the android side

Not all of them but your right, it has to do with Android and not ES100.
On the other hand, when you select 990/909 kbps be aware that connection is much weaker than in adaptive, due to data load on the Bluetooth transmission and LDAC behavior. Plus some devices reset it to adaptive when connection is not good, like Sony WH-1000XM3, but ES100 does not.

So I've been messing around my Android's Dev options and I found that you can manually set the bt audio sample rate. So I was messing with 96k. While I'm able to set it to 96k, Everytime I start up the es100 it would go back down to 44.1k and have to go back to the settings and put it back to 96. Now this is not some discussion about 44.1 vs 96k, I'm just curious if it's the es100 that's putting it back down to 44.1. since I askednon my.phones discord and they suggested that it's what evers connected to the bt that's putting it back down.
Not sure I understand... when I start up my ES100 the app on my Android phone it always reports I have 96Khz/24bit. I don’t have to set anything.

For what it's worth I'm on a 7t on Android 10. And I did an experiment, it still resets to 44.1k even if I leave es100 on. Maybe it just resets to default when theres no audio output over bt after x time?

Edit: it's actually only defaulting back to 44.1 everytime I manually skip a song. So it will stay 96k if i just let it be

On another note would this be a problem of I go wired mode? As in I connect the dac to my phone and use it as a USB dac? Cause I'm kinda confused by the USB dac mode in the settings it says it defaults to 44.1k/16bit? Or does it automatically adjust depending on the file?

Mine unfortunately defaults to 24bit/44.1k

In Settings, is your phone’s Bluetooth connection to ES100 set to highest quality or best connection?

I think we should ask google about that

Not sure what is your question. These developer options reset everytime you reboot, turn off Bluetooth in your device... I set them just after connect ES100 always to 24bit, 96kHz and 990/990 kbps and pretty happy :gs1000smile:

Sorry, can you guide me how/where you change the bitrate settings in an Android? Thanks in advance!

Odd. I have the opposite problem. My phone, a Samsung Galaxy S7 Edge, always defaults to LDAC 24 bit 96 kHz. I often change it to 24 bit 44.1 kHz because almost all my source audio is 16 bit 44.1 kHz and upscaling to 96 kHz seems like it should be both imperfect and a waste of battery. I would set it to 16 bit, but LDAC doesn't seem to support this and upping the bits per sample is trivial and lossless anyway.

LDAC, as per Sony's design, will always resample any incoming signal to 24/96 by default before transmission. I am surprised that Samsung even let you change the sampling rate at all.

Odd. The developer options always default to 32 bit 96 kHz, but according to the ES100 app it delivers 24 bit 96 kHz. After changing the options to 16 bit 44.1 kHz, the ES100 reports 24 bit 44.1 kHz. So it forces 24 bit but allows changing sample rate.
