SK-AM62: Missing Echo-cancellation module in PulseAudio 13.0

I have tried to build pulseaudio but having issues from the download package: 

http://freedesktop.org/software/pulseaudio/releases/pulseaudio-13.0.tar.xz 

Hi Andreas, thanks for your reply.

Yes, module-eco-cancel.so is what we are looking for and seemed to have missed the SDK version of Linux. Would you be able to provide the pulseaudio-module-echo-cancel_13.0-r0.0_aarch64.ipk ?

Thanks

Amazing!

Thanks a lot for this. 

I tried to build this in past and failed at the following step:

$>MACHINE=am62xx-evm bitbake -k tisdk-default-image

I left it overnight to build but was stuck in some stage forever. 

Trying to rebuild this now. 
Thanks.

This can happen if you don't have enough physical memory and/or swap space allocated. Please try to build on a machine that has at least 16GB of RAM, and 16GB of swap space available, this is a combination I never had any issues with for any of our builds. Alternatively, you can configure Bitbake to reduce the number of parallel make operations / threads being used, see local.conf.

Hi Andreas, this is what I get at the end of the make.

Hi Andreas, sorry for multiple questions.

Would you be able to share steps on how to build ipk package for pulseaudio but of different version and not pulseaudio13 ?

Thanks

Except ti-rtos-firmware you list there those are rather large packages that are failing, hence no image is generated. What machine are you building this on? Can you try one that meets the requirements I listed earlier? And have you experimented with reducing the number of parallel make operations / threads being used, see local.conf, as suggested earlier?

At a minimum you'd need to do two things:

1. Update the filename of the recipe oe-core/meta/recipes-multimedia/pulseaudio/pulseaudio_13.0.bb to change the 13.0 version number embedded there to something else (that needs to be valid!) by checking what's available on the server. The recipe derives which source package to download from the version number in the filename
2. Update the source package hashes inside oe-core/meta/recipes-multimedia/pulseaudio/pulseaudio_XX.Y.bb to reflect the updated source packages you are using

Then, the patches in the recipe folder may or may need to get updated or dropped, depending which version you are using. You can also try to simply grab and drop in/replace the entire oe-core/meta/recipes-multimedia/pulseaudio/* folder from a different Yocto branch (like Kirkstone?), assuming the package version there is different and what you want.

Hi Andreas, I got a new virtual machine sorted with Linux 18.04 and 16Gb of RAW and swappable memory and rebuilding these. I also changed the local conf as per your suggestions and running this again to see if I can build the lot. 

In terms of pulseaudio, in the end I managed to do the similar changes as you mentioned. So thanks for the confirmation (at least I know, I am on the right track). Changed the recipe file and changed related patch and local files and managed to get the IPK files built, and now started building latest ALSA as there was dependence on it. 

However, I would like to understand the 'Kirkstone' approach.  

When I try to access Kirkstone repo using https://git.yoctoproject.org/kirkstone/plain/

I get error to say no repo found. COuld you please let me know how to access the repo so that I can take the the entire multimedia package. Thanks 

Sorry, just noticed Yocto branch (like Kirkstone?) in your reply.

Will try to switch branch. Thanks. 

Hi Andreas, not sure if you would have any time to look at this:

looks like the webrtc recipe is needed but can't find in the yocto master branch as well (under multimedia)

Hi Mitesh,

the issues you are facing are very userspace-specific and not something we can support through the forum here, which is mostly concerned with enabling/using TI devices in the context of Linux. As for your specific issue I suggest you do an internet search for the keywords you see, and/or check in with the pulseaudio community (that's what I would do if I were in your shoes). If you do find however that there's something "TI specific" getting into your way preventing this from working, let me know.

Regards, Andreas

Thanks Andreas, for all your support. I understand. 

Cheers.
