Audio Configuration
I have been trying to verify audio capture and playback functionality (using ADAU1761 codec and NOT HDMI) for the past few days.
So far I could get the board to playback audio from line in to line out & hph out but audio capture through mic & line in are not working. And I couldn't play audio or speaker-test on it.
which settings should i change to play audio and capture?
you can see some settings of my device below

Hello Emre,
This is a lot to go through.
What hardware are you using?
Have you downloaded SigmaStudio? It helps you to see the signal flow all on a few window tabs.
Then you can capture the register settings and then figure out how to get the driver to set it up. The mixer and control numbers are on the diagram so that will help since it looks like the defines are using those names.

Hi Dave,
Thank you for your message. Here's the information you requested:
I am currently working with the Zedboard (adau1761) Rev F for my audio processing project. Yes, I have downloaded SigmaStudio and installed it on my system. I've successfully generated a bin file using SigmaStudio according to this link. However, I'm encountering difficulty integrating this file into my Petalinux image. Could you provide guidance on which directory I should place the bin file in? In the link there is an explanation below.
"It is also possible to install the firmware file on the root filesystem. This allows to update it without having to update the whole kernel. To install it on the root file system copy it to the “/lib/firmware/“ folder on the target system."
In my system there is no firmware folder under lib. You can see below.
zed_aud:/$ ls

zed_aud:/$ cd lib/

Additionally, I'm wondering if there is a generic bin file available for the adau1761 placed on the Zedboard. This would greatly facilitate my project. My goal is to route audio from the line-in input to my PC and vice versa, utilizing the line-out. Any insights or resources on achieving this would be greatly appreciated.
Lastly, I'm seeking sources or references that explain audio concepts, particularly regarding audio codecs. Having a better understanding of these concepts would greatly aid in my project development.

Hi eogut ,
Did you get any feedback ?
Load the firmware on the target system
I got the same issue. instead of loading the firmware on the target system according to this link, i copied adau1761.bin file into /lib/firmware/ directory.
Welcome to Buildroot
buildroot login: root
#
#
# ls
#
#
#
#
# ls /lib/firmware/
adau1761.bin
#
I have this error:
# dmesg | grep adau
[ 4.137517] adau1761 0-0070: Direct firmware load for adau1761.bin failed with error -2
[ 4.151445] adau1761 0-0070: Could not find firmware file: -2
Please i need your feedback.
Best regards,
