Well this has me completely confused I'm afraid. What the above shows
is that the very same script, the one that is failing to start
Squeezelite after 5 attempts when triggered by the udev rule, works when
called manually from the command line. i.e.:
The udev rule calls the script at 331.27 seconds in:
Code:
--------------------
[ 331.27] Script parameters: restart M6 1-1.2
--------------------
This apparently failed to start Squeezelite 5 times.
The manual script call was at 356.94 seconds in:
Code:
--------------------
[ 356.94] Script parameters: restart M6 1-1.2
--------------------
This evidently managed to start Squeezelite at the first attempt.
And it's not even the script itself that is failing - it's being
triggered with the right parameters, the built-in restart command is
being called correctly and is attempting to start Squeezelite, but seems
to fail to work in the former case:
Code:
--------------------
sudo /usr/local/etc/init.d/squeezelite restart
--------------------
I can see no reason for this, and what's doubly confusing is that I
don't see this behaviour with either of the USB DAC setups that I have
here, yet you clearly have a very standard setup. I will have to think
carefully about how to isolate the problem.
Since I can't recreate the problem, the only way I can think to tackle
it is to ask you to do some experimenting:
At the point where you called the script manually, could you try some
different steps. So, from the top:
1) Re-run the 'install' option but without the --nostop option. This
should recreate the rules file with both options. Reboot.
2) Disconnect the DAC. This should kill the Squeezelite process.
Code:
--------------------
ps | grep squeezelite
sudo /usr/local/etc/init.d/squeezelite status
--------------------
3) Reconnect the DAC. The expected behaviour would be for Squeezelite to
restart, but we know that in your case this is not working - it fails
after 5 attempts. At this point, instead of issuing the restart command
manually from the command line, let's see what's going on:
Code:
--------------------
ps | grep squeezelite
sudo /usr/local/etc/init.d/squeezelite status
--------------------
