Subject: Re: ecasound stop unexpectedly... more info needed
To: Kai Vehmanen <kvehmanen@email-addr-hidden>
Hi,
There is no unusual output from jackd. The ecasound logfile is very long.
I have pasted the begining and the end below, cutting out a big chunk from
the middle. This time when running the code I included a break statement if
the engine-status command returns anything other than "running".... so I
never had to hit Control-c to stop it. This time it ran for about 5 seconds
before stopping. I have included the code again below the log file output.
Maybe you can try it on a system and see what you get?
Thanks so much,
Francis
