Only first say block ist working

[peacepro]

If I use more than one say block, only the first say block is working. The second block is not working.

I can't test right now (traveling). sayText is a quite simple wrapper around ev3dev.Sound.speak() https://github.com/OpenRoberta/robertalab-ev3dev/blob/develop/roberta/ev3.py#L367

I have a repro:

_brickConfiguration = {
...     'wheel-diameter': 5.6,
...     'track-width': 18.0,
...     'actors': {},
...     'sensors': {},
... }
hal = Hal(_brickConfiguration)
hal.setVolume(100)
hal.sayText("Hello"); hal.sayText("and"); hal.sayText("good evening");
aplay: main:722: audio open error: Device or resource busy
# more lowlevel, still broken
hal.sound.speak("Hello").wait(); hal.sound.speak("World").wait();
aplay: main:722: audio open error: Device or resource busy
# but this works:
hal.sayText("Hello"); hal.waitFor(200);hal.sayText("and"); hal.waitFor(200); hal.sayText("good evening");

# this is what we essentiall do from python via Popen, but in a shell it works
espeak --stdout "Hello" | aplay -q; espeak --stdout "World" | aplay -q

Somehow closing the device takes longer than the subcommand runs ??

Ahhh, https://github.com/ev3dev/ev3dev-lang-python/issues/461 - too bad that there is no new release :/
