Hello, you're probably right, but have to found what have change or
cause this trouble.
So, when I play some sound on LMS and got "alsa_open:533 unable to set
hw params: Broken pipe" , the audio device seems "frozen" :
Code:
--------------------
pi@multiroom:~ $ sudo aplay -D USB0 -vv /root/test1.wav
aplay: main:828: audio open error: Device or resource busy
pi@multiroom:~ $ sudo fuser -v /dev/snd/*
USER PID ACCESS COMMAND
/dev/snd/controlC0: root 375 f.... alsactl
/dev/snd/controlC1: root 375 f.... alsactl
/dev/snd/controlC2: root 375 f.... alsactl
/dev/snd/controlC3: root 375 f.... alsactl
/dev/snd/controlC4: root 375 f.... alsactl
/dev/snd/controlC5: root 375 f.... alsactl
/dev/snd/controlC6: root 375 f.... alsactl
/dev/snd/pcmC3D0p: root 957 F...m squeezelite
/dev/snd/pcmC5D0p: root 954 F...m squeezelite
--------------------
asound.conf is :
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 don't have more knowledge to go further, if you have an idea to found
what's possibly wrong, tell me.
Thanks for help.
