Hi,
I received the following report for Debian package.
It sounds possible, considering the privilege it is running under,
but nasty.
> If ecasound runs with double buffering and under root, almost any kind
> of termination of the process causes complete computer freeze:
> /usr/bin/ecasound -b:4096 -z:db,661500 -r:99 -f:16,2,44100,i -i
> alsahw,0,0 -o stdout
>
> It exits properly, if I stop it as follows:
> killall -STOP ecasound; killall -KILL ecasound
>
> Another way to stop ecasound safely is to run it with tee like this:
> /usr/bin/ecasound -b:4096 -z:db,661500 -r:99 -f:16,2,44100,i -i
> alsahw,0,0 -o stdout | tee audio.raw > /dev/null
>
> And then kill the processes in following order and with following delay:
> killall -9 tee; sleep 1; killall -9 ecasound
>
> Looks like ecasound does not tolerate any signal when it is in system
> call (read kernel mode) of any kind.
regards,
junichi
