Node.js Speaker isssue

Good morning everyone,

Since 2 month I'm working on a node.js mp3 player on my raspberry pi. I used the npm package player (https://www.npmjs.com/package/player) which worked fine with the defaut raspberry jack.

Last week, I order a HifiBerry DAC Standard phone jack to get a better sound. I've installed everything with the tutorial (https://www.hifiberry.com/guides/configuring-linux-3-18-x/). My player load the first music and everything it's ok. But when I need to play the second music on the playlist (Player.next), the program breaks. That never happen before with the defaut rapsberry sound card. Program logs :

im playing... src:"DCUP - Im Corrupt (Viceroy remix).mp3"
DCUP
undefined
next
[ 'Breakbot - Star Tripper (Audio Only).mp3',
'Breakbot',
'Star Tripper (Audio Only)',

The main message error is [../deps/mpg123/src/output/alsa.c:165] error: cannot open device default . I think alsa is not configured correctly. My etc/asound.conf :

pcm.!default {
type hw card 0
}
ctl.!default {
type hw card 0
}

I don't understand why alsa cannot get the defaut device only on the second music. Alsa.c is a part of the speaker package ; it's used to send sound to the sound card. You can find sources here : https://www.npmjs.com/package/speaker

 

Does anybody have any idea of what happen here ?

Thank you

Rémi Bruyère
