Sample rate no higher than 44.1kHz

Help and Support Help

I’m looking into a problem I seem to have where everything is being played at a 44.1 kHz sample rate. My set up is RPi 3, Hifiberry Digi+ Standard, Simaudio Moon 100D, with a Jolida amp. The Digi is connected through the S/PDIF. The only part of the system that is grounded is the Jolida amp, and I’m running the newest build of Volminio.

Volumio says on screen that the sample rate is 44.1kHz and that’s what is reading on my DAC, although I have tested songs and tones at much higher sample rates. I have tried turning the sample rate converter in Volumio off and to native with no success.

Any help would be appreciated.

yes, something is wrong.
just tested. I play flacs 44,1khz 16 bit, upsampling 192khz 24 bit, volumio shows 44,1khz 16bit and my DAC 192khz!

Thats intresting, meanwhile I play mp3’s and volumio shows 44,1khz in 24bit, can I choose upsampling in volumio? If yes, where?

ok, I found it bit still my Volumio shows the native sampling rate, so my guess is that the upsampling happens right before the output,
so when the sound leaves the source the sound has the samplerate that you have choose in your volumio setup.

or maybe it´s possible we have to reboot our source to make the changed sample rate happend.

that´my five cents.

and then I found this in /etc/mpd.conf

[code]audio_output {
type “alsa”
name “alsa”
device “hw:1,0”
dop “no”
mixer_device “hw:1”
mixer_control “Digital”
mixer_type “hardware”

	format      "192000:24:2"

}

audio_output {
type “fifo”
enabled “no”
name “multiroom”
path “/tmp/snapfifo”
format “44100:16:2”
}

#replaygain “album”
#replaygain_preamp “0”
volume_normalization “no”[/code]

what does the audio_output type fifo and format 44100:16 means?
