is resampler enabled automatically ?

[sureshkn]

Hi,
I have RPi2 with Audiophonics ESS9023 V2 I2S DAC. I belive 9023's max configuration is 24 bit, 192Khz.

In boot/config.txt
dtoverlay=hifiberry-dac is enabled.

And in the UI.,
Audio output interface = HifiBerry DAC (I2S)
Volume control = disabled.

I played following tracks (downloaded from http://www.lindberg.no/hires/test/)
2L-125_stereo-352k-24b_04.flac
2L-111_stereo-352k-24b_15.flac

These tracks are 24bit, 352.8Khz. Confirmed by foobar & MediaInfo. RuneAudio's Playback UI also shows as 24bit, 352.8Khz.

But when I do.,
[root@runeaudio ~]# cat /proc/asound/card1/pcm0p/sub0/hw_params
access: RW_INTERLEAVED
format: S24_LE
subformat: STD
channels: 2
rate: 192000 (192000/1)
period_size: 16384
buffer_size: 65536

it shows are 192Khz. Does it mean resampler is enabled automatically when sample rate is greater than 192Khz or is resampler is always on ?

Regards,
Suresh.

Hi Frank,
Thanks for your reply. Where can I change the soxr options ? I think it should be in mpd.conf, but I did not find anything related to soxr.

I have iFi nano iDSD USB DAC as well. It is capable of 32bit/384kHz. Tonight will test with that.

Regards,
Suresh.
