[Solved] Strange behavior of Volumio2

[aseg]

Hardware: Audio Injector Octo on raspberry pi 3B +
Volumio 2.457 2018-09-17, no apt-get update

If I launch the Volumio2 web client, everything works well before installing the card (jack output).

Installing the card in Volumio with /etc/asound.conf and .asoundrc, then SSH:
Aplay -L: Ok
speaker-test -c 8: Ok, the 8 channels work

-> Playback Options (web page)

-Audio Output
-Output Device: audioinjector-octo-soundcard
-I2S DAC: Off

-Playback options
-DSD Playback Mode: DSD Direct
-DSD Auto Volume Level: Off
-Volume Normalization: Off
-Audio Buffer Size: 8MB
-Buffer Before Play: 10%
-Persistent Queue: On

-Volume Options
-Mixer Type: Hardware
-Mixer Control Name: DAC1
-Default Startup Volume: 50
-Max Volume Level: 100
-One Click Volume Steps: 10
-Volume Curve Mode: Natural
-MPD Clients Volume Control: Off

-Audio Resampling: Off

I can only listen to the webradios, not the shared music of Windows10 (which works with the configuration without the card => jack output).

If I try to play a shared music, I get an ECONNRESET error :

This happens also sometimes when launching a web radio (1 time out of 4).

Any idea ?

Thanks

Some news.

Installing the card removes alsa PCM mixer, that gives this strange behavior.

I keep searching...

I added -
{"id":"audioinjector-addons","name":"Audio Injector Octo","overlay":"audioinjector-addons","alsanum":"1","mixer":"","modules":"","script":"","needsreboot":"yes"},
- to /volumio/app/plugins/system_controller/i2s_dacs/dacs.json.
I put I2S DAC on ON and chose Audio Injector Octo. I changed Mixer Type to Hardware and made a trial with Volumio version 2.513. Everything works!
