Hi there,
I am running a RPi 4b with Raspbian (Bullseye), LMS 8.2.0 and
Squeezelite 1.9.9. For automated startup of the Squeezelite process
whenever my USB DAC is connected, I have defined the following *udev*
rules:
Code:
--------------------
SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device",
ENV{PRODUCT}=="154e/300a/3", RUN+="/usr/bin/DAC_start.sh"
SUBSYSTEM=="usb", ACTION=="remove", ENV{DEVTYPE}=="usb_device",
ENV{PRODUCT}=="154e/300a/3", RUN+="/usr/bin/DAC_stop.sh"
--------------------
This is my *DAC_start.sh* script:
Code:
--------------------
#!/bin/sh
######### DAC_start.sh #########
date >> /tmp/udev.log
echo "Starting Squeezelite" >> /tmp/udev.log
sleep 5s
/usr/bin/squeezelite -o hw:CARD=ND8006,DEV=0 -D -n MediaPlayer -d all=debug
-f /tmp/sq.log | at now
###############################
--------------------
This is my *DAC_stop.sh* script:
Code:
--------------------
#!/bin/sh
######### DAC_stop.sh #########
date >> /tmp/udev.log
echo "Stopping Squeezelite ..." >> /tmp/udev.log
pkill squeezelite
###############################
--------------------
Both scripts work fine when I execute them manually (both as pi and
root: Squeezelite successfully connects to my LMS and USB DAC, music can
be played.
The *udev* rules also work and get fired when I connect my USB DAC
(which I can see from the log files).
However, when squeezelite gets started from the *udev*, squeezelite
seems to be unable to connect to my LMS which is on the same LAN,
actually on the same machine. This is the Squeezelite logfile:
Code:

--------------------
It seems as if Squeezelite, when started by *udev*, has no network
access? I used the approach described above on a RPi with piCorePlayer
OS, and it worked like a charm...
Any ideas what I am doing wrong?
Thanks,
Sven
