I am trying to run camilladsp on the newly released Ubuntu 23.04 on a raspberry pi. Everything seems fine but I am having some issues installing pycamilladsp and pycamilladsp-plot. Previously I installed these with the commands:
sudo pip3 install git+https://github.com/HEnquist/pycamilladsp-plot.git
sudo pip3 install git+https://github.com/HEnquist/pycamilladsp.git
When running these commands I now receive the following error.
I then installed pipx and was able to install pycamilladsp and pycamilladsp-plot but it seems like if the modules are installed this way they cannot be imported as I get the following error when attempting to run the GUI.
I am able to install pycamilladsp and pycamilladsp-plot via pip3 if I add --break-system-packages but not sure if this is something I should be doing. Is using --break-system-packages OK? Is there are way to install pycamilladsp and pycamilladsp-plot via pipx where they can imported when running the GUI?

Most likely they implemented this to prevent people from messing up their systems. Probably a good thing overall, but makes some things a little harder.
pipx isn't useful here.
If it's still allowed to use pip to install in the user home for that's probably the easiest. Try "pip install --user git+http://GitHub.com/etc etc"
If that doesn't work then virtual environments are the way to go. There are many ways to handle that. Either plain virtualenvs, or using tools such as conda or pipenv. Not sure what I would recommend.

Thank you for the info, trying this generates the same error. Using "sudo pip3 install git+https://github.com/HEnquist/pycamilladsp.git --break-system-packages" seems to work fine. As everything works I guess I won't worry about using "--break-system-packages".
Michael
Older versions of pip always run as if --break-system-packages is given. Using this to install a single package that isn't available in the system repos is normally safe. But if that package has dependencies that are not already installed, then pip will install those too from pypi. If that then installs something that is also available via the system repos (for example numpy) then things can get messy.
Thanks for the info, that all makes sense. One good thing from the change in pip behavior is I realized I was being inconsistent with installing packages via apt and pip. It somewhat forced me to clean up my tutorial to use apt for all packages (other than pycamilladsp and pycamilladsp-plot).

Well, I reckon your tutorial is exemplary, however you will just get the clean up done in time for more updates when Henrik releases CamillaDSP v2.0
https://github.com/HEnquist/camilladsp/blob/next20/README.md#persistent-storage-of-state
Henrik, is there going to be a beta release of V2.0 ?
Yes but I want to get a bit further on the gui before starting with that.
Hi experts,
Sorry to bother you again, but I am quite confused with the channel mapping into the blackhole 16-ch instance I am using on MacOS. I tried to figure it out by displaying the waveform on Audacity, and it appears to be in the order of front left, front right, surround left, surround right, front center and the subwoofer. However, VLC seems to map them to all over the places among the 16 channels of blackhole. Then, playing with Audacity shows a completely different mapping except first two, and actually it sounds like some channels missing. Did you experience something like this?
Regards,
Jay

Regarding the post above, I think I made a small progress through speaker config@audio MIDI setup, but I still seem to see incorrect mapping. I set center/subwoofer to be 3rd/4th channels, but now consistently getting them as 5th/6th channels. Not sure what's going on, but I guess it may be okay as long as it's consistent?
Well, as long as you know - is it really a problem?
Apple seem tp have the same default order as the backside of your DAC.
But you should be able to assign any channel to any speaker in Audio/MIDI..

Hi, Does anyone have experience of using this virtual AES67 ALSA device on a RPi4 with CamillaDSP? It looks a little complicated to me, but that's probably because I don't really understand most of this stuff. I just follow the instructions and hope any niggles don't take too long to shake out.
I've already managed to get roonbridge and librespot-java working seamlessly with CamillaDSP in the kitchen. AES67 would give me access to Dolby processing on the Trinnov located remotely in the cinema room, which I'd like to experiment with.
On the separate topic of integrating control of sources and CamillaDSP, I'm using Node-RED to tie everything together. We use the individual apps for Roon and Spotify to select and launch music, after which we use a Harmony Elite to control volume and transport. Node-RED detects a new source playing, and controls CamillaDSP's config and the amplifiers, stopping and restarting the stream if needed to avoid missing the start of the track. If anyone's interested I can share the flow.

I fixed that a while ago but then forgot about it and never published the new version 🤪

does the websocket api operate as a request-response? e.g. if I set a new config, do I have to wait or a response before sending reload or can I just hit it with a stream of commands?
As long as the stream of commands is sent in one connection they will be processed in the order they are sent. The websocket server always sends the response after executing the command, before picking the next from the queue.
If you send the commands on different connections however there are no guarantees unless you wait for the response for one command before sending the next. Each connection is handled by a dedicated thread.

is there an option to tell SetConfig to validate (and only set if it is valid) or does that have to be a request-response?
is there a working example (running on linux) of rew -> aloop -> camilla -> aloop -> rew anywhere? I can do it at cli using arecord/aplay but it's not super convenient. REW doesn't seem to let one choose subdevice which (based on what might appear to be feedback recorded) suggests it is recording itself.
