@kevindpatino Messaging you about the noise in the matrix creator recording before and after the update.
1- Thank you for report the matrixio-creator-init issue: Missed libmatrixio-creator-hal as a dependency. https://github.com/matrix-io/matrix-creator-init/releases/tag/v0.4.7
2- Just to confirm did you follow:
- MATRIX Creator/Voice Hardware Test
- Could you check:
$ cat /sys/module/spidev/parameters/bufsiz 12000
I saw the test files that you sent me here. So, It seems something went wrong with the installation.
How was the test?
The output was
How was the MIC test? Did you get the same results?
Yes, still noisy. Sample data here: https://drive.google.com/open?id=1C4fVE8aDzKkCpVUATH9vgrxdLbSKSk-u
Did you talk or make a sound or this is a silent record?
I was watching something on youtube
Ok, just one test: Could you setup a 1KHz tune and record? Could you send this records?
Sure. I uploaded here: https://drive.google.com/open?id=1gCqQBEBopJT4i0xw-eoy0unQT-UCA0Li
Did you set it up close to your MATRIX Creator?
around 0.5 meter away
Could you test it closer, less than 5cm and increase the volumen as louder as you can? We could hear some of the 1KHz, but as you said the noise is louder than the 1KHz signal.
updated the file, same link
btw, the noise is not coming from an ambient source i think it is related to the processing as the recorded signal has distortions.
left side is the recording using the laptop microphone, right side is the matrix recording
I will send you a direct message, in order to handle it.
Have you seen my reply? What is the next step?
We found the bug , could you run:
1- If you install the kernel modules with
sudo apt remove --purge matrixio-kernel-modules sudo apt update sudo apt upgrade sudo reboot #After reboot sudo apt install matrixio-kernel-modules
2- If you compile the kernel modules:
sudo rm /boot/overlays/matrixio.dtbo sudo rm /lib/modules/$(shell uname -r)/kernel/drivers/mfd/matrixio*.ko sudo reboot #After reboot sudo apt install matrixio-kernel-modules
3- If you use HAL examples, just a simple pull of the repo and compile again the examples.
Let me know how it work now.
Thanks @kevindpatino a lot! This saved me from doom!!!
Would you be able to give even a brief explanation on the fix?
Seems to work better now specially with the 1khz tone test. Not sure if I am nitpicking though but channel 0 and 1 have a different envelope than the rest of the other channels.

I try it ，but it not work
