Failed to encode speech buffer with aic3101 on dm365

Jingwei Song

Hi,all.

We use the chip aic3101 on dm365(dvsdk_2_10_01_18&mv_pro_5.0) to collect the sound. We add the chip driver in kernel. After kernel boot these info printed :

Advanced Linux Sound Architecture Driver Version 1.0.12rc1 (Thu Jun 22 13:55:50 2006 UTC).
ASoC version 0.13.1
AIC3X Audio Codec 0.2
asoc: aic3x <-> davinci-i2s mapping ok
ALSA device list:
#0: DaVinci DM365 EVM (aic3x)

I think that the driver is worked. Then we loadmodules.sh and do the encode cmd: ./encode -s test.g711

the error comes: 

# ./encode -s test.g711
Encode demo started.
hUI->osd = 0
Error: Failed to encode speech buffer

Do anyone have advices about this problem?

Any information you need feel free to ask me.

Thanks.

    Hi, Mr.Song, we  meet the same problem like you. You can try to cat to sure that your hardware and  driver have worked and getted the raw data.

     cat /dev/audio>audio1

    best regards!

    Hi，xu !

    Thank you for reply. We try the cmd "cat /dev/audio>1.g711" for 45 seconds, and found that the 1.g711 file recorded the sound.

    But the cmd with "./encode -s test.g711" ERROR happened yet.

    Error: Failed to encode speech buffer

    Could you give me more advise?

    you can change the 1.txt to 1.g711 or others use the player who can decode sample: 8k u-law to listen.
