Can not start Alsa

Phong · May 9, 2016

hi all,

My Orange Pi PC here:

uname -a
Linux orangepipc 3.4.112-sun8i #30 SMP PREEMPT Sat Apr 30 19:49:10 CEST 2016 armv7l GNU/Linux

and dmeg like this

[    1.017014] asoc: sndcodec <-> sunxi-codec mapping ok
[    1.017964] [DAUDIO]sunxi-daudio cannot find any using configuration for controllers, return directly!
[    1.018158] [I2S]snddaudio cannot find any using configuration for controllers, return directly!
[    1.018174] [DAUDIO0] driver not init,just return.
[    1.021480] asoc: sndhdmi <-> sunxi-hdmiaudio.0 mapping ok

and I check status of ALSA lib

# systemctl status alsa-state.service

That why I can not list devices: arecord -l

**** List of CAPTURE Hardware Devices ****
arecord: device_list:277: control open (0): Invalid argument
arecord: device_list:277: control open (1): Invalid argument
arecord: device_list:277: control open (2): Invalid argument

How can I fix this? Thank

Please tell us what you want to achieve, so we can help you . ~~There are no errors in your outputs.~~

OpiPC has only got two PlayBack Devices, HDMI and Analog Out via 3,5mm Jack.

I have checked Things on my OPiPC and now I think your Problem could be, that you are not part of the Group "audio".

Regards

As I posted, I can not list device hardware with: arecord or aplay

aplay -l
**** List of PLAYBACK Hardware Devices ****
aplay: device_list:277: control open (0): Invalid argument
aplay: device_list:277: control open (1): Invalid argument
aplay: device_list:277: control open (2): Invalid argument
Segmentation fault

Always return: Segmentation fault

And that why I can not hear anything from speaker or record anything via mic.

In history, I installed alsalib 1.1.1 from: ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.1.1.tar.bz2

After that alsalib load fail.
