ADAU1761 Sound Output Issue Inquiry

Hello MOOG,

I went into SigmaStudio and pulled out an ADAU1761 but you could pull out a 1361 as well. Then I dropped in the USBi interface and connected it.

I setup the communications protocol to be SPI so I would not have to have hardware to do this.

Then I set up the playback path with all the outputs on like this:

Then I clicked on all the controls to set them into the correct mode and I pulled up the Capture window and selected all the lines. You cannot do CTRL-A you have to click on the first one and then shift-click on the last one.

It looked like this:

Then I hovered the mouse over the selected area and right clicked and selected "save as Text"

This is what the start of the file looks like:

This is the file I ended up with:

So go through this file and then go through your code to see if you are enabling all the correct signal paths. You have to look at the defines and figure out which registers they are for. The define names should be similar to the control name so that would help.

Then make sure you are sending the correct register writes.

Hello Dave,

I came across a piece of information stating that uploading a bin file to Linux only includes DSP information, and I only recently understood this. I've confirmed that it uploads correctly, but there's something I'm really curious about, and solving this seems like it would be the final step.

DAC ON/OFF
-> I used alsamixer to set options like Mixer 3/4 Enable or Mixer7 Enable, but the most critical part, unmuting the DAC, doesn't seem to work as MX3LM and MX4RM don't change to Unmute. Can you provide any guidance on this?
If I need to modify the code, which part should I look at? I'm really at a loss here.

The photo below shows the current codec state read by the Sigmastudio tool Playback Output read aftersetting it up with alsamixer.

Thank you !

Hello Moong,

I am also at a loss. I am not a Linux expert and have no platform here to do any Linux work. You had posted a couple of times in the Linuz space and the manager of that space simply moved it over to the Audio space or SigmaDSP space. I support the SigmaDSP and audio codec products so that is not exactly wrong but your issues is falling into the cracks between these two worlds.

Your approach of using the alsamixer options is what I was talking about from the start. To use sigmaStudio to develop what the registers need to be and then looking at the defines in the Linux driver to see which defines control those registers. I would look at all the defines and look at the register addresses you need to change. Somewhere there will be a place where the register address is defined. Many of the registers will have several bit fields so those will be defined with similar names. Then somewhere in the code all the bit fields will be "OR"'d together and written to the register using the name in the defines.

That is what you need to look for. You are doing well so far by finding the mixers. Make sure the volume controls are up. Regarding the mutes, do what I suggest and search the header files for the hex or the decimal address of the register. It could be listed as hex but it also could be listed as decimal.

I tried to respond to your PM but your settings do not allow me to respond. So send me a friend request.
