All the tests involving CHOWTapeModel.component fail #32

LucaMarconato · 2021-09-22T17:06:30Z

I have create a conda environment, installed pybind11 and tox via conda and run tox. But all the tests involving CHOWTapeModel.component fail.

Some more details (please tell me if you want more information):

macOS BigSur 11.4
Python 3.8.12

Any idea?

Hi @LucaMarconato! I do indeed more information - what errors do the tests fail with? Any useful stack traces or error messages?

Hi again @LucaMarconato - just an FYI that I'm going to close this in a week if it's no longer an issue, as I don't really have any information to go off of (and I've been unable to reproduce the issue).

Hi, sorry for the delay in answering, here is my full output from tox, do you need any extra information, like the full conda environment info?

Thanks @LucaMarconato! A couple more things to try:

Do you happen to be running on Apple Silicon? (i.e.: an M1 Mac) The CHOWTapeModel.component plugin in the repo is compiled for x86, so I'm not entirely sure what would happen if you tried to load it on an M1 Mac.
If you copy CHOWTapeModel.component into ~/Library/Audio/Plug-Ins/Components/:
- Does auvaltool -al list the plugin?
- Does auvaltool -v aufx Jdox Chow (to run validation on the plugin) complete successfully?
- If you have a plug-in host installed, can you see CHOWTapeModel in the list of available plug-ins?

Hi again @psobot! I ran into the same issue as @LucaMarconato and thought I could help answer these questions. I am running on a M1.

Does auvaltool -al list the plugin?

Yes, it is listed as aufx Jdox Chow - chowdsp: CHOWTapeModel (file:///Library/Audio/Plug-Ins/Components/CHOWTapeModel.component/)
Does auvaltool -v aufx Jdox Chow (to run validation on the plugin) complete successfully?

Yes it does. It returns AU VALIDATION SUCCEEDED.
If you have a plug-in host installed, can you see CHOWTapeModel in the list of available plug-ins?

I can see the plugin and use it as well!

HussainAbdi · 2021-12-15T00:59:19Z

After adding CHOWTapeModel.component to ~/Library/Audio/Plug-Ins/Components/, all these component test cases pass. Not sure why, but I've left it there for now.

HussainAbdi · 2021-12-28T07:20:45Z

FYI for anyone facing this issue, I had the same problem on a non-M1 MacBook Pro (2016 13-inch MBP) and it was resolved the same way as above. Adding CHOWTapeModel.component to ~/Library/Audio/Plug-Ins/Components/.

psobot · 2021-12-30T00:30:42Z

Thanks @HussainAbdi and @LucaMarconato! I'm adding a change to fix these tests and raise a more descriptive ImportError if the plugin fails to load. It seems that on M1, or in certain unknown configurations, plugins are required to be installed to ~/Library/Audio/Plug-Ins/Components or they'll fail to load.

* Fix tests when running on M1 macOS. Fixes #32. * Add more verbose error message even if not on Apple Silicon. * Run black. * More pythonic test code. * Lint.
