Hi,
I added external/alsa-lib, external/alsa-utils, hardware/alsa_sound
from git to my android build tree.
Changed BoardConfig.mk as below,
BOARD_USES_GENERIC_AUDIO := false
BOARD_USES_ALSA_AUDIO := true
BUILD_WITH_ALSA_UTILS := true
Added asound.conf to (my_target)/system/etc.
------------------------------------
# #
# # Mixer devices
# #
ctl.AndroidPlayback {
type hw
card 0
}
ctl.AndroidRecord {
type hw
card 0
}
# #
# # Playback devices
# #
pcm.AndroidPlayback {
:
:
------------------------------------
Build success but I got the following error when run my target board:
-----------------------------------------

-----------------------------------------
I can see my alsa device "cat /proc/asound/cards",
but "alsa_aplay -l" said
aplay: device_list:217: no soundcards found...
Can anyone give me some suggestion?
Thank in advance.
