Testing Audio interface from command line

[Aashish Patel]

Hi,

I am using android 4.4 (Build from ASOP) on my pandaboard ES. I want to test sound (recording and playback) from command line.

I have tried setting all the controls using tinymix and tried testing using tinyplay and tinycap but not getting anything.

Tested Following things:

1) I am getting system sound (all touch sounds ,alarm,notification)

2) tinyplay testaudio.wav (no sound)

testaudio.wav (44.1khz and 48khz)

the 48khz one show playing sample but I am not geting any sound in headset.

then it exits prompting 

error playing sample

3) tinycap /data/Test_cap.wav -d 0 -c 2 -r 48000 -b 16 -C 

(nothing)

I am trying to compile alsa for arm (from its source) using toolchain from codesourcery, able to configure but make fails with error

For alsa-lib

CC=arm-none-eabi-gcc ./configure --prefix=/home/vvdn-64/alsa/alsa-lib-1.0.27.2/utils/ --host=arm-none-linux

in src/control/cards.c

sys/ioctl.h No such file or directory

I tried commenting that file then some other errot pops up , it shows endian.h error.

Please suggest something from which I will be able to test using alsa or tinyalsa

Thanks in advance
