Orange PI PC, No sound [RESOLVE]

marl

I tried OrangePI-PC_Ubuntu_Vivid_Mate and OrangePI_Jessie_Xfce images from here http://www.orangepi.org/orangepi ... d=342&extra=&page=1


All is working except no sound in AV port. I'm not using HDMI, I used HDMI to VGA converter coz my monitor don't have HDMI.

Did some work on this today:

Set HDMI output as default:

1. cat << _EOF_ > /etc/asound.conf
   
2. pcm.!default {
   
3.    type hw
   
4.    card 1
   
5. }
   
6. 
   
7. ctl.!default {
   
8.    type hw
   
9.    card 1
   
10. }
    
11. _EOF_

Copy code

Set 3.5mm as output:

1. cat << _EOF_ > /etc/asound.conf
   
2. pcm.!default {
   
3.    type hw
   
4.    card 0
   
5. }
   
6. 
   
7. ctl.!default {
   
8.    type hw
   
9.    card 0
   
10. }
    
11. _EOF_

Copy code

Test with:

1. speaker-test

Copy code

You can mute/unmute the 3.5mm (lineout) channel with:

1. amixer set -c 0 'Audio lineout' unmute
   
2. amixer set -c 0 'Audio lineout' mute

Copy code

I get an error when using type plughw in asound.conf:

1. ALSA lib dlmisc.c:252:(snd1_dlobj_cache_get) Cannot open shared library /usr/lib/arm-linux-gnueabihf/alsa-lib/libasound_module_pcm_plughw.so

Copy code

However, i can run speaker test using plughw on both devices.

1. speaker-test -Dplughw:1
   
2. speaker-test -Dplughw:0

Copy code

It is a permissions problem.

Your user must be in the audio group to access the audio filesystem object. Normally "orangepi" user is not member of such group, in fact if you run speaker-test from root you should get audio from analog. More than this, as normal user you aren't even able to run alsamixer, because you don't have permissions.

To gain normal user access to audio, just add orangepi user to audio group in /etc/group, then log out and log in.
Nonetheless in my setup audio is quite low in volume when I run audio applications as standard user. It is ok when I run it as root.

I'm facing the same problem. In my case I'm using HDMI video output without converters.

Not muted. Just needed to disable the hdmi output so the other channel work. If two are enabled there is no output. That is what I have observe. So I fix mine by doing that.

Run alsamixer and set mm of lineout.

Hello!
What do you mean"disable HDMI output"? Should I mute it in alsamixer or make some changes in X settings?
