Hello squeezebox community !
I'm actually facing a strange problem with squeezelite.
My goal is to achieve a multiroom rack system based on a Raspberry
running 6 squeezelite instance and 6 PCM2704 chinese DAC
The architecture system is :
Since these chinese DAC always got the same serial number or PID VID , I
firstly have to map USB permanently to avoid DAC mismatching at reboot
.
I've done that by use a rules.d as follow :
Code:
--------------------
SUBSYSTEM!="sound", GOTO="my_usb_audio_end"
ACTION!="add", GOTO="my_usb_audio_end"
DEVPATH=="/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.2/1-1.2.4/1-1.2.4.4/1-1.2.4.4:1.0/sound/card?",
ATTR{id}="USB1"
DEVPATH=="/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.2/1-1.2.4/1-1.2.4.2/1-1.2.4.2:1.0/sound/card?",
ATTR{id}="USB2"
DEVPATH=="/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.2/1-1.2.2/1-1.2.2:1.0/sound/card?",
ATTR{id}="USB3"
DEVPATH=="/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.2/1-1.2.4/1-1.2.4.3/1-1.2.4.3:1.0/sound/card?",
ATTR{id}="USB4"
DEVPATH=="/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.2/1-1.2.3/1-1.2.3:1.0/sound/card?",
ATTR{id}="USB5"
DEVPATH=="/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.2/1-1.2.1/1-1.2.1:1.0/sound/card?",
ATTR{id}="USB6"
LABEL="my_usb_audio_end"
--------------------
I've then definited an alsa conf tog get correct audio output and
mixer/equalizer
Code:
--------------------
#USB1
ctl.USB1 {
type equal;
controls "/opt/alsa/USB1.bin";
}
pcm.USB1 {
type equal;
slave.pcm "plughw:USB1";
controls "/opt/alsa/USB1.bin";
}
#USB2
ctl.USB2 {
type equal;
controls "/opt/alsa/USB2.bin";
}
pcm.USB2 {
type equal;
slave.pcm "plughw:USB2";
controls "/opt/alsa/USB2.bin";
}
#USB3
ctl.USB3 {
type equal;
controls "/opt/alsa/USB3.bin";
}
pcm.USB3 {
type equal;
slave.pcm "plughw:USB3";
controls "/opt/alsa/USB3.bin";
}
#USB4
ctl.USB4 {
type equal;
controls "/opt/alsa/USB4.bin";
}
pcm.USB4 {
type equal;
slave.pcm "plughw:USB4";
controls "/opt/alsa/USB4.bin";
}
#USB5
ctl.USB5 {
type equal;
controls "/opt/alsa/USB5.bin";
}
pcm.USB5 {
type equal;
slave.pcm "plughw:USB5";
controls "/opt/alsa/USB5.bin";
}
#USB6
ctl.USB6 {
type equal;
controls "/opt/alsa/USB6.bin";
}
pcm.USB6 {
type equal;
slave.pcm "plughw:USB6";
controls "/opt/alsa/USB6.bin";
}
--------------------
I then got a service than run an sh bash script as follow :
Code:
--------------------
#! /bin/sh
# Run mutliple squeezelite instance as deamon
sudo squeezelite -z -n Cuisine -m 00:00:00:00:00:01 -o plug:USB1 -a 80:::0 -r

sudo squeezelite -z -n Exterieur -m 00:00:00:00:00:05 -a 80:::0 -r
32000,44100,48000 -o plug:USB5 -C 5 -G 19:H -f ~/squeezelite_ext.log
sudo squeezelite -z -n Free -m 00:00:00:00:00:06 -a 80:::0 -r
32000,44100,48000 -o plug:USB6 -C 5 -G 26:H -f ~/squeezelite_res.log
--------------------
_*The_problem_*_
all is apparently work especially with web radio it seems ok , but when
I change a song or play a youtube sound, there is no more sound output .
Why ? I don't know, tried a lot things, but since i'm not really expert,
cannot facing what's going wrong .
Logs of one squeezlite instance for example :
