Bug Description

In the Alsa UCM it is useful to have the all the device information, if specified on config files, when a verb is set.

Attached is a patch from Margarita Olaya that is implementing the UCM on Pulse, I have tested it on a TI Panda Board and it works fine.

version: alsa-lib 1.0.24.1
Ubuntu version: Natty

Patch was tested with the next command:
alsaucm -c <yourSoundCard> set _verb <yourVerb> get _verb set _enadev <yourDevice.x> list _devices get PlaybackPCM

Has anybody tested this patch? Its not yet in upstream alsa-lib git, and unless its been tested, I would feel more comfortable taking it when upstrea has accepted it.

As noted in the bug description, this patch was tested on a panda (armel) system. As UCM is currently supported on SOC hardware only, I don't see any harm in pulling this commit early. Also, it was pulled into Liam Girdwood's branch, so it should be in alsa-project soon.

@luke: patch has been ack'd upstream by liam (main developer of UCM), see http://mailman.alsa-project.org/pipermail/alsa-devel/2011-March/037842.html. is that good enough for inclusion in natty? we definitely need this for pandaboard, and that was tested by TI on panda.
