           Summary: Alsa plufin for pulseaudio
           Product: OpenMoko
           Version: 2007.2
          Platform: Neo1973
               URL: http://www.pulseaudio.org/wiki/PerfectSetup
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Applications & Dependencies
        AssignedTo: mickey at vanille-media.de

An alsa application such as aplay can fail returning: 
aplay: main:545: audio open error: Device or resource busy

because pulseaudio (or another alsa app) is using /dev/snd/pcmC0D0p

A solution would be to install the alsa plugin for pulseaudio [1].

Could you please add these packages?
They already exist in openembedded:
libasound-module-ctl-pulse - 1.0.14-r0 - Alsa plugin for ctl-pulse
libasound-module-pcm-pulse - 1.0.14-r0 - Alsa plugin for pcm-pulse

once the packages are installed
aplay -Dpulse file.wav 
works :-), since /etc/asound.conf already defines a pulse device.

For having this behaviour by default, these lines can be added to

pcm.!default {
    type pulse
ctl.!default {
    type pulse

For some reason, it does not work if these lines are added to /etc/asound.conf
