cat /proc/asound/Audio/stream0 | grep Momentary

Mint 20.2

cat /proc/asound/Audio/stream0 | grep Momentary

Is it true that above command will show what computer (ALSA) is actually sending to a separate DAC?

I have a PC with an optical SPDIF from motherboard to the separete DAC (it upsamples from 44100/16 to 96000/24; TubeMagic D1 DAC).
I have also a USB connection to that same DAC. I can choose between those, all ok so far.

But I don't seem to get 44100hz resolution to the DAC?
Momentary freq = 48000 Hz (0x30.0000) this stays same, what ever I do.

Code: Select all

pacmd list-sinks | grep "sample spec"

This value changes (with optical connection) depending what music player shows, but "momentary" still stays at 48000hz (even this shows 96000).
With USB both will stay at 48000hz. I don't seem to get a differences using ALSA or PulseAudio from the settings with DeaDBeeF or Audacious.

I don't seem to get any differences, even I try to change multiple configuration files. Probably I am changing wrong files or with wrong commands...

So my question in short is: who is resampling everything to 48000hz before my DAC and how do I change that?
Or is that "Momentary" information wrong somehow?

I would like to get my ripped cd's (44100/16) digitally to my DAC without PC (dmix?) resampling them first to 48000hz.

Obviously I would like to use PulseAudio alone or with ALSA (not only ALSA); and Pipewire in the future.
