The output sample bit rate is not always accurate. For example when playing 24/192 will show 32/192.
Anyone else noticed?
Which player are you using? In most cases the player will just use whatever source bits it has 16,24,32 and sends them in the most significant bit of 32 bit samples. I checked with JRiver Media Center where you can actually control the output bit depth and the S1 correctly switches between the selected formats. See attached

I have used it with LG V50 with USB audio player Pro. Hopefully with the next update they will fix the the sample bit rate issue.

The PAW S1 works correctly and displays what it is being send. Sending 16 or 24 bit samples in the most significant bits of 32 bit audio samples is likely exactly what you want. USB Audio player Pro has an option to force 16 bit samples for phones that might struggle with the bandwidth of 24 or 32 bit audio sample. If you select this option you will see the display on the PAW S1 reflect this. However this will truncate any sample with higher bit depth so it is not recommended. So USB Audio player Pro is also doing the right thing?

The bit rate rather than the bit depth also tracks what is being send correctly according to my tests on JRiver and the phone.

So I am not sure there is anything to fix for Lotoo or USB Audio Player Pro.

well, on its way, it’s going to be a fun weekend if it makes it before Friday to Mexican customs, whenever it arrives, ill
Be happy to compare this 2. Been meaning to get e1da products though the g3 sounds the most appealing since I’m an iOS user. This is going to be fun!

Kind of surprised so many people have units at hand already. I’m in China and the S1 has been sold out on Lotoo’s JD store (kind of China equivalent to Amazon) for ages:
