full audio stack up. The AESS IP does not have driver. You need to
disable CONFIG_OMAP_RESET_CLOCKS. This will fic the audio playback speed.
As for the basic usage:
We support up to 5 channel playback on OMAP4 in Legacy mode:
channel 1/2 (stereo): Headset, earpiece
channel 3/4: Handsfree/Line out
channel 5: Vibra
So with stereo sample you can only play to the Headset/Earpiece.
You need to have 5 channel audio, and valid data on channel 5 to be able
to drive the vibra.

Audio support on OMAP 3430LDP or 4430SDP boards
Can someone please hint on what audio is supported on these two OMAP boards? From what I can tell, the answer is either nothing or hdmi, both of which are useless to me if someone wants me to convert the OMAP ASoC driver to DMA engine. From what I can see on the 4430SDP, there's a 3.5mm headset jack, microphones and speakers on the board, so the board does have audio hardware. However, it seems (as, I'm afraid to say, seems to be pretty much standard practice with OMAP) there's a total lack of software support in mainline. This kind'a prevents me testing changes to the DMA support for OMAP ASoC... What can be done to remedy this situation?

Association of Building Engineers? I had noticed that there's sound/soc/omap/snd-soc-omap-abe-twl6040.ko which needs a bunch of other modules, but even this doesn't cause any cards to show up. So, I'm guessing that the real answer to my problem is that there is no functional audio support on any OMAP board I have, and, therefore, I am unable to continue with the work which TI would like me to do. That's great. That's really bloody well great. I'm going to leave this in Santosh's hands to deal with, and arrange to get more complete and functional board support for any board that TI send me into mainline - for example, I _still_ don't have any working video output on the 4430SDP board. Utter crap. In fact, the only things that do work on the 4430SDP are serial and network. At least the 3430LDP has video output on its LCD. When will support for OMAP based platforms become a reasonable reality? When will people stop pissing around with utterly shit incomplete board support? I'm shelving further OMAP work until board support for these targets improves to a state where a reasonable amount of the platform is supported. Until that time I'm not wasting any more of my time trying to work out what I can do to assist OMAP along. -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

So it sounds like if I rebase stuff forward to -rc4, it should start working? Right, so that was the problem. Why not say in the first place that it required -rc4 instead of just saying that it was in v3.4-rc ? It's taken severeal frustrating hours to get to this point... But.. if I repeatedly aplay /dev/zero, I get randomly spat out on the console: omap_hwmod: mcpdm: _wait_target_disable failed If I play a raw PCM audio file with aplay (44.1kHz s16le 2ch), I get several of these from time to time: DMA synchronization event drop occurred with device 66 and the 'noise' from the small loudspeakers is just about recognizable - but is not what I was expecting (it's slow, plus it sounds on those small speakers that it's horribly distorted.) I can't get the headset jack working to be able to play it through a decent sound system, through which I'll be able to actually _hear_ what the corruption is. I've tried fiddling with everything in alsamixer, including turning on the vibras in the hope of some kind of output (at least that does spin the motors.)
