Follow steps for configuring audio devices
https://developers.google.com/assistant/sdk/guides/service/python/embed/audio
I went through the guide and tested the speakers as described. I can hear the voice playing.
I then launched orangeassist and ran my query again, same error.

Can you paste what’s in your .asoundrc file
.asoundrc
pcm.!default {
type asym
capture.pcm "mic"
playback.pcm "speaker"
}
pcm.mic {
type plug
slave {
pcm "hw:0,0"
}
}
pcm.speaker {
type plug
slave {
pcm "hw:0,0"
}
}
result of aplay -l

arecord -l lists no devices so I have tried the .asoundrc file with the pcm.mic section and the reference removed but it didn’t make any difference.

Did you install portaudio
sudo apt-get install portaudio19-dev libffi-dev libssl-devThe only other thing I could think of is that your audio devices is busy. Do you know how to setup snooping for pi? If not, let me know and I will give you instructions
Edit: looks like I did here
That will allow your audio devices to be used concurrently by any process
Yes, but I did it again just to be sure:
sudo apt-get install portaudio19-dev libffi-dev libssl-dev libmpg123-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
libffi-dev is already the newest version (3.2.1-6).
libmpg123-dev is already the newest version (1.23.8-1).
libssl-dev is already the newest version (1.1.0j-1~deb9u1).
portaudio19-dev is already the newest version (19.6.0-1).

Tested and same issue.
I updated my .asoundrc file to match yours in the thread you linked (my HW IDs are the same):
pcm.snoopedmic {
type dsnoop
ipc_key 2241234
slave {
pcm "hw:0,0"
channels 1
}
}
pcm.mixedspeaker {
type dmix
ipc_key 2241234
slave {
pcm "hw:0,0"
channels 1
}
}
pcm.!default {
type asym
playback.pcm {
type plug
slave.pcm "mixedspeaker"
}
capture.pcm {
type plug
slave.pcm "snoopedmic"
}
}
Still the same issue:

Yep. It looks like this project is probably going to replace that one, if I can just get some time. I’m also trying to get Shinobi set up and having some “fun” reading the H.264 stream from one of my RPi cams. MJPEG works just fine so I may just give up and move on. I only have three cameras so it’s not like I need that many resources anyway.
I’ll get back to this this weekend I hope.
@luckymallari, I never touched python before.
Now I followed your tutorial and it worked up to this point:
I’m able to talk to my assistant and it switches lights for example.
But I don’t understand how to connect to this python-machine via http.
Which port/url do I use?
And I had to choose a device-type - there I selected “speaker”.
Is this relevant?
EDIT: It works now 
After setting debug to false I reached the host/port from the config.json
EDIT2:
WORKS: Switch on < light >
WORKS: Remind me to < something > at < time >
DOESN’T WORK: play < movie > on netflix on shield
DOESN’T WORK: play < song > on < device or group >
Go to config.json and set debug to false. You will more configuration stuff there. Use the html tester so you know what to send to the url when you configure OH
@luckymallari technically it works now - but many commands don’t get a result. Especially the “play music on device” commands. Neither in english nor in german.
Did you register your device using the device tool (part of the SDK) and you can confirm your instance shows under your Google Home app?
I am having problem to create an instance of the device.
googlesamples-assistant-devicetool register-device --model "rpi-assistant-7cf1b-rpi-assistant-o137ha"
i just receive Error: Missing option “–project-id”.
Have tried with
googlesamples-assistant-devicetool register-device --project-id "rpi-assistant-7cf1b" --model "rpi-assistant-7cf1b-rpi-assistant-o137ha"
Same error.
How did you do it
EDIT I did not success with the command but now i see it in my Google Home 
/Mike
Is it possible to run tester from a remote computer?
I am running this on a pi without browser.
/Mike
Yes. It’s a rest api
What is the url to tester.html.
/Mike
When i tigger how’s my day it does not respond in my Google Home.
/Mike
Well of course. It won’t trigger your GH. The code itself is the assistant. You get the response through the API. You need to trigger routines if you have routines set in your GH app. I had mine to broadcast “my day” to the kitchen GH device.
Spent all night trying to figure out why this won’t run… Was using this -
root@ubuntu1:/orange-assist# python3.7 -m orangeassist
when i should be using this incase someone needs it
root@ubuntu1:/orange-assist# python3.7 -m or
And in general, you shouldn’t be using root
