Hi -
I have one pandboard (4430), however, it's said the audio and
audiohw not supported in the Linaro android release 11.11 or 11.12,
Well, the alsa driver side is working, the two main issues left are
about integration with pulse and fixing an issue with one channel of
audio record.
So if you update to latest pulseaudio and run this script for example
with a 48kHz stereo wav
#!/bin/sh
amixer cset name='DL1 Mixer Multimedia' 1
amixer cset name='DL1 Media Playback Volume' 118
amixer cset name='Sidetone Mixer Playback' 1
amixer cset name='SDT DL Volume' 120
amixer cset name='DL1 PDM Switch' 1
amixer cset name='Headset Left Playback' 'HS DAC'
amixer cset name='Headset Right Playback' 'HS DAC'
amixer cset name='Headset Playback Volume' 13
aplay -Dhw:0,6 -M -f S16_LE -r 44100 -c 2 test48.wav
audio should be coming from headphone jack on Panda OK.
so is there one way to add the support manually ? if yes, where to
begin ? I am also interested in enabling the video hw support for the
board, but no idea until now.
Do you mean just video output at all? It should be working well from
HDMI jack. If you mean accelerated video multimedia decode, this is
very close to being there but has a latency bug we didn't get a chance
to look at yet

once that's solved it should be workable end-end.
