TLV320AIC3111: No sound output after PurePath studio download project

Hi Zhou,

Is your project also writing the rest of the configuration necessary to get the device running? The register settings are also loaded to the device with PPS, doing the same role as the EVM software would. This includes powering on the output drivers, setting the miniDSP as the processing stage, etc.

Best regards,

Hi Jeff McPherson 

I didn't write anything else.

Do you mean the SystemSettingsCode is not enough for the device running?

If so, can you provide the full SystemSettingsCode? I use TLV320AIC3111EVM-K and don't change anything.

Hi Jeff McPherson ：

Now it can output, but when I add Parametric Equalizer and build code, I get error as follows:

Can you tell me how to resolve it?

I also attach my project, you can use it directly.

2260.ProcessFlow_3111.pfw

Hi Jeff McPherson:

Is there any workaround with PPS(because other comompent have this issue too ,such as loudness)?

And the latest version I download from TI is 5.95, is there any update version?

Hi Zhou,

No, unfortunately Purepath Studio is no longer in active development. The version you got from ti.com will be the final version.

The only work around with regards to the PEQ is to use individual biquad blocks to create the filters. You can also use the PEQ block to create your filter, take note of the coefficient values found in the properties window, and then copy these to the biquads before deleting the PEQ block.

I just tried to use the loudness component and didn't get any errors. Note that a volume block is required with loudness block for it to function.

Hi Jeff McPherson ：

Thank you.

After I add Volume component, the error remove. 

About PEQ, as I test, both AIC31XX, DAC31XX, TSC2117 PEQ will get same error.

Is there no solution for all these ics?

If so, I think I will use your advice.

Hi Zhou,

That is correct that the PEQ is broken for all devices. I analyzed the code of the block and found conflicts. However because there is no software support for this program I cannot make an update. I may accidentally break other things if I try to fix it.

Best regards,

Hi Jeff McPherson :

Can you provide me a test version so that I can use PEQ in my project?

I will check whether other things are broken or not in my project.

Hi Zhou,

Unfortunately not. Again the software support for this has long been gone. We have no experts on the internal code structure to support edits like this.

Hi Jeff McPherson ：

Thank you for you help.

I will close this question.
