Hi,

I am using beagleboard Xm revC1 with kernel image 3.4.7 built using origin/v3.4.x at https://github.com/RobertCNelson/stable-kernel/tree/v3.4.x.
I tried playing .wav file using music player and no sound is heard on headphones.

cat /proc/asound/cards shows “— no soundcards —”.

Any idea whether Audio works with this image with default configuration?
Also there is no asound.conf file. What show this be set to for beagleboard?

Audio works with ulcdlite Angstrom image and sound is heard. I am trying to get audio working on ubuntu. Any help will be appreciated.

Regards,
Ketan

Hi,

This seems to be linked with bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1019321

running following commands, devices do appear but no sound.
modprobe snd-soc-omap
modprobe snd-soc-omap-mcbsp
modprobe snd-soc-omap3beagle

No sound could be due to https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1022578

Is there any fix planned for this?

Regards,
Ketan
