new jukebox: high-definition music playing at lower quality

[adamdmoss]

I have a bunch of 48KHz music, some 192KHz 24-bit etc.
According to my DAC's readout, it's being fed 44.1KHz/16-bit audio data by the new jukebox.

I could have sworn that an earlier version of the new jukebox branch was playing hi-def files at their native rate.

Did something change? Did I only hallucinate this working in the past? I may have screwed up my ALSA config and accidentally forcing 44.1/16 but I don't think so (also tried without an asound.conf at all).

@adamdmoss Can you help me investigate on that issue ?

Can you change the log level to DEBUG for package com.github.biconou.AudioPlayer ? You can achieve that in several ways depending how you run Airsonic.
Here is one suggested method (https://airsonic.github.io/docs/logging/)

Now inspect what appears in the airsonic.log file.

At jukebox player initialization you should see something like that.

In my case, we can see that my card number is 1 and it supports both normal and High resolution audio formats.

Now I play a hi resolution file, and I can see that in the log file.

2017-09-23 17:05:03.804 DEBUG --- c.g.b.AudioPlayer.JavaPlayer             : Player com.github.biconou.AudioPlayer.JavaPlayer@c89ba2a : Play

While playing, if I use a terminal and type this

cd /proc/asound/card1/pcm0p/sub0

cat hw_params

I can see that.

subformat: STD
channels: 2

Can you do the same and it will help me understand what goes wrong ?
