[meta-ti] Sound on Pandaboard?

[maniacbug]

Hi. As mentioned before, I'm running "Yocto (Built by Poky 7.0) 1.2" on Pandaboard with meta-ti. Thanks for the previous help on video, "ffplay" from libav (ported from openembedded) is playing video only now (not audio).


As a simple test, I'm now trying to play an MP3 file with gaku (the Sato music player). This results in 3 lines of the following per attempt:

Jul 25 13:48:23 pandaboard user.warn kernel: [ 30.949951] SDP4430 Media: asoc: SDP4430 Media no valid playback route from source to sink

aplay gives the same result, and adds:

ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
aplay: main:682: audio open error: Invalid argument

Is there anything particular I should be setting up in meta-ti to enable audio?  (Or should this question be posed on the yocto list instead?)

Thanks,
