Omap5432: ASoC: no backend DAIs enabled for OMAP ABE Media1

Hello Srikanth,

I looked your problem for this purpose I made some test on OMAP5uEVM with glsdk-6.01.00.01.

I didn't find pulseaudio in the directory - /usr/bin/, there isn't such file. Could you explain your steps to enable Backend audio.

I suggest to check in file - omap-abe-twl6040.c and omap-abe.c, there are ABE subsystem configurations. If there is hardware problem.

This problem can be caused by Lunux audio driver or see in module-alsa-card.c. Do you use ALSA app for playing pulseaudio?

I checked that pulseaudio problem is very common in Linux, refer to similar topic in this forum - http://e2e.ti.com/support/embedded/linux/f/354.aspx

Best regards,

Yanko

Hi Yanko,

I have added it in local.conf :

IMAGE_INSTALL_append = " pulseaudio"

and rebuilt the arago-glsdk-console-image.  This will install pulseaudio in the rootfs and you can find the binary. Just run the pulseaudio, once the target boots completely.

You'll notice the series of dev_err messages on console.

Thanks,

Srikanth

Hello Srikanth,

I suggest to use the latest GLSDK release - 6_02_01_02 release.

This release adds following features on top of 6.01.00.01 release:

• Audio input/output through McASP/ABE using ALSA.
• ....

Download the latest GLSDK from link - http://downloads.ti.com/dsps/dsps_public_sw/glsdk/6_02_01_02/index_FDS.html

Best regards,

Yanko

Hello Yanko,

Which page did you extract the below listed notes ?

• U-boot support for booting from QSPI, eMMC and UART (J6 only).
• U-boot supports dhcp / tftp commands (J6-only).
• File system support (kernel drivers) for eMMC, QSPI, NFS.
• Audio input/output through McASP/ABE using ALSA.

Thanks for the updates !!!

Hi Srikanth,

This is from GLSDK release notes. http://processors.wiki.ti.com/index.php/OMAP5_GLSDK_6.02.01.02_Release_Notes , but some from listed notes are paraphrased.

Best regards,

Yanko

Hello Yanko,

In latest SDK 6_02_01_02, I can see pulseaudio is built and installed. But If I run the pulseaudio command on the console, I am getting same error messages :

Any pointers would be really helpful.

Hi Srikanth,

I suggest to run this command -

Running a gstreamer pipeline -  '''target #''' gst-launch playbin2 uri=file:///<path_to_file> videosink=kmssink audio-sink="alsasink device=hw:1,0"

Try to play pulseaudio again.

Best regards,

Yanko

Hello Yanko,

I can play the gstreamer command and display shows up a frozen initial screen (with picture content) nothing actually plays :

Thanks for you support and help.

Hi Yanko,

Are you able to run pulseaudio without the errors mentioned above ?

Thanks,

Srikanth

Hi Sricanth,

I also have the errors from your logs. I started to investigate the problem and I marked that $HOME/.asoundrc file is missing; /etc/asound.conf file is empty .

There are a lot of missing parts in this release to be able for running pulseaudio.

I am looking in this link http://www.alsa-project.org/main/index.php/Asoundrc to get more information about alsa driver.

I will forward pulseaudio problem to GLSDK team to give explains.

Best regards,

Yanko

Hello Yanko,

Thanks a lot for confirmation.

Regards,

Srikanth

Hi Yanko,

Any updates on this ? Were you able to get any comments from dev team ?

Thanks,

Srikanth
