If you follow the steps here:  http://www.omappedia.org/wiki/Android_Panda_Build_Source#Building_from_Linaro you will get a Linaro Android release where Audio works.

I don't know if this will help as I know next to nothing about Linaro but,

The audio was not working in Ubuntu either until after installing the "Ubuntu-OMAP4-extras".  The line that seemed to help was:
"$ /usr/bin/alsaucm -c PandaES set _verb HiFi"
This fixed sound through the 3.5mm, I have no idea about the HDMI audio as I haven't tested it.

There's a similar command for the non-ES version.  Not sure if that would help in Linaro or not.

I am having difficulty getting audio to play from my Pandaboard (which is running Linaro Android 4.1.1).  Any suggestions for getting audio to work?  I have two Pandaboards and the audio works on neither of the boards.  I can provide any other information if necessary.  I've tried using the 3.5mm audio jack and HDMI and neither works.

Thanks.  I followed the instructions but I got an error when I entered the following command:

$tar -jxvf android-toolchain-eabi-linaro-*

The error was:

tar (child): android-toolchain-eabi-linaro-*: Cannot open: No such file or directory

tar (child): Error is not recoverable: exiting now

tar: Child returned status 2

tar: Error is not recoverable: exiting now

It looks like it's having trouble finding the tool chain.  I downloaded the file under "Tool Chain for building Kernel and Drivers".  Does it need to be in a certain location or have a certain format?  Thanks for the help.

Dear Kacyn,

First of all, the link below has been updated:

http://www.omappedia.org/wiki/Android_Panda_Build_Source#Building_from_Linaro 

1. Download the toolchain:

wget --no-check-certificate http://android-build.linaro.org/download/linaro-android_toolchain-4.7-bzr/lastSuccessful/archive/build/out/android-toolchain-eabi-4.7-daily-linux-x86.tar.bz2

2. Unzip it as shown below:(use the full name of the toolchain)

tar -jxvf android-toolchain-eabi-4.7-daily-linux-x86.tar.bz2

It should work successfully.

Cheers,

Jayneil.

Hi,

Thanks for letting me know.  Just curious - what was changed between the old and new versions of the link?  Also, have you gotten this working on the Pandaboard ES Rev B1?  The link doesn't include the testing results from this revision.  Thanks for your help.

Dear Kacyn,

I have gotten all these instructions working on the Pandaboard ES Rev. B1. I updated the link again to include this board. Thanks for pointing that out. The major changes were: toolchain version, troubleshooting section.

Cheers,

Jayneil.
