X86 ALSA Sound Issue

[Skuld]

Hi All:

I port to alsa-sound alsa-lib on X86 system and I use alas_ctl produce
asound.conf to /system/etc/.

When I tried to play Music Player on Android system, time line of
music player isn't correct and it can't play audio.
How to fix it? Thank you..

I modified init.rc file and add following .

# change permissions for alsa nodes
symlink /dev/snd/pcmC0D0c /dev/pcmC0D0c
symlink /dev/snd/pcmC0D0p /dev/pcmC0D0p
symlink /dev/snd/controlC0 /dev/controlC0
symlink /dev/snd/timer /dev/timer
chmod 0777 /dev/pcmC0D0c
chmod 0777 /dev/pcmC0D0p
chmod 0777 /dev/controlC0
chmod 0777 /dev/timer
chmod 0666 /dev/binder
chmod 0666 /dev/ashmem
#following are new lines
chown root audio /dev/snd/controlC0
chown root audio /dev/snd/pcmC0D0c
chown root audio /dev/snd/pcmC0D0p
chown root audio /dev/snd/timer

Can you post your asound.conf ? I am using this one.
I don't know it it works... I am working on a eeepc 701.
Btw... You just modified the USES_ALSA_AUDIO... in mk file and added
the lines in init.rc (and moved asound.conf in the right place), isn't
it?
Tonight I'll try to copy a song in sd partition.

I finally got my sound working. I tested it outside Android with
aplay. Alsa-utils can be downloaden now from the Android repository. I
used alsactl store in Ubuntu to get an asound.state. With the values
from that file I created my own asound.conf. It looks a lot like the
one in my alsa thread.

Congratulations!

Could you post your asound.conf, just to see it and understand
correctly its structure?
Mediaplayer is working?

[Androidphan]

My asound.conf can be found here:
http://pastebin.com/f41e6b204

I also added the following to init.rc :
setprop alsa.mixer.playback.master Front
setprop alsa.mixer.capture.master Capture
setprop alsa.mixer.playback.earpiece Master
setprop alsa.mixer.capture.earpiece Capture
setprop alsa.mixer.playback.headset Master
setprop alsa.mixer.playback.speaker Master

I don't know how to play video files yet, haven't tried actually.
But I ran Mediascanner from Dev tools, then it found my mp3 inside
'Music' and that played well.

It probably is possible to add alsa-utils to your local_manifest and
put BUILD_WITH_ALSA_UTILS := true inside your BoardConfig.mk and then
run alsa_ctl.

Hi people,
I followed this discussion and I'm trying to do what you did and
I just need the configure line you used for both alsa-lib and alsa-
utils

thanks,

I just downloaded the alsa-lib and alsa-utils with repo, you need to
download it with a local_manifest file.
Then turn on BOARD_USES_ALSA_AUDIO := true and
BUILD_WITH_ALSA_UTILS := true at asus/eee_701/BoardConfig.mk.

Then it builds Android with the alsa library and the alsa utils. Then
you need a proper asound.conf to get your sound working.

[dmoti]

Thanks!
I did it with this local_manifest.xml:

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
<project name="platform/vendor/asus/eee_701" path="vendor/asus/
eee_701"/>
<project name="platform/external/alsa-lib" path="external/alsa-lib"/>
<project name="platform/external/alsa-utils" path="external/alsa-
utils"/>
</manifest>

it took me a while to figure it out so I'm puting it here for future
generations :-)

it synced OK but when I build it I got this:

make: *** No rule to make target `out/target/product/eee_701/obj/lib/
libaudio.so', needed by `out/target/product/eee_701/obj/EXECUTABLES/
alsa_amixer_intermediates/LINKED/alsa_amixer'. Stop.


any ideas?

Thanks Androidphan,

I think that the problem is that I didn't have hardware/alsa_sound
package so I added it to
the local_manifest.xml now the problem is:

make: *** No rule to make target `vendor/google/frameworks/maps/
com.google.android.maps.xml', needed by `out/target/product/eee_701/
system/etc/permissions/com.google.android.maps.xml'. Stop.

It's not related to the alsa_sound addition I made since it fails like
this even without it.
can someone provide a little bit more details regarding the build
setup:
the contents of localmanifest platform compiler and library used in
case that the problem is with my setup
(I tryied ubuntu 8.10, 9.04 with gcc-4.2)

Found a solution:

edit ./build/target/product/generic_with_google.mk

and put under remark 3 lines starting with PRODUCT_COPY_FILES (with
#)

I'm not sure about remarking the gtalkservice but since every compile
takes a long time I didn't have a chance to test it.

keep in mind that it'll probably disable google maps and gtalk!

also I noticed that the alsa utils executables are prefixed with alsa_
and placed at /system/bin/

Audio works!

final tip:
I've ran alsa_ctl store on a live Ubuntu on the machine it created a
file: /var/lib/alsa/asound.state
I've stored the file into /system/etc/asound.conf on the Android disk,
loaded Android and ran alsa_ctl restore 0.

thank you all for your help!

Hi，make a disturb

how to get the alsa－util，and what's the main effect about alsa-lib？

you need this 3 lines added in you local_manifest:

<project name="platform/hardware/alsa_sound" path="hardware/
alsa_sound"/>

<project name="platform/external/alsa-lib" path="external/alsa-lib"/>
<project name="platform/external/alsa-utils" path="external/alsa-
utils"/>

alsa-utils are some alsa related command-line tools like aplay
alsa_ctl and amixer
which are playing configuring and controlling the mixer respectively.
alsa-lib is a library that this alsa-tool depend upon (I think)
and if I understand correctly alsa_sound is the interface between
anddroid and alsa.

to enable all of this in the compilation add this 2 lines to your
BoardConfig.mk

BOARD_USES_ALSA_AUDIO := true
BUILD_WITH_ALSA_UTILS := true

Bump... I am stuck at the same error (about android.maps.xml) when I
did a repo sync after completely unrelated changes. Is anyone able to
help?

Is is possible to add sound to eee pc without rebuilding android?

[ehung]

Hi dmoti
I have follow your tips to implment alsa function.
I have built the libaudio.so, alsa_ctl, alsa_amixer and alsa_aplay on
android system.
I use a aplayer application to test the alsa function, but the audio
still not work.
Could you give me some suggestion?
Thank in advance.

Best Regards,
ehung

Hi all:.
This is my test result below. Could someone give me some suggestion?

I can launch alsa_aplay -l and audio card is listed.

Launching alsa_aplay file.mp3 and it tells me "unable to install hw
params".

Launching alsa_amixer -c 0, it has show some information below.
Simple mixer control 'Master' ,0
Capabilities: pvolume pvolume-joined pswitch pswitch-joined
Playback channels: Mono
Limits: Playback 0 - 13
[1] Segmentation fault alsa_mixer -c 0

When I set the Audible selection on settings of UI, the logcat message
will show
E/MediaPlayer: Unable to to create media player.

That's all for my test that I can do it what I know.

Thanks in advance again.
Best Regards,
ehung
