Pulseaudio, just avoid-resampling = true

Hi.
Im tryng to get the output exactly as the audio input.

I download some files from this site:
https://www.mitsue.co.jp/english/servic … ation.html

The thing is that im getting always the same Bits:
For example for a 32bit 192000Khz im getting this:

sudo cat /proc/asound/IQaudIODAC/pcm0p/sub0/hw_params 
access: MMAP_INTERLEAVED
format: S16_LE
subformat: STD
channels: 2
rate: 192000 (192000/1)
period_size: 661
buffer_size: 2644

Yep, the rate is good, but not the bits! because im seeing "s16le".
What could be wrong here?

In the daemon.conf i set the avoid-resampling = true, just that.

So, if it is avoiding resampling... what is going on?

"pacmd list" give me this:

And who are the 5 clientes????

Also if i put just a file on loop of 32bit 192000Khz. Im getting this:
