Enable audio output on A20?

[wsteven2]

Hello,

Trying to redirect audio output from my laptop, but first it should be working locally on my board shouldn't it?

I don't know much about how audio is working. Any help much appreciated.

Have you tried with mplayer?
What version of A20 are you using? micro? lime? lime2?

[wsteven2]

Hi Rouvas,

It's the MICRO version.

With mplayer :

Well, the answer is in the output of mplayer:

May the file you try to play is corrupt?

[wsteven2]

I reckon message looks like an mp3 problems. But I have similar problems with every file. Most probably the clearer message would be this one :

Especially the "[AO_ALSA] alsa-lib: pcm_direct.c:1505:(_snd_pcm_direct_get_slave_ipc_offset) Invalid value for card". Which I saw once in dmesg.

Can you please check that you have a properly configured /etc/asound.conf ?

In the "pcm.dmixer", the "hw:1,0" is for HDMI sound and "hw:0,0" is for analog sound.

Seems that you somehow have lost the /etc/asound.conf

[wsteven2]

You're the man!
Thanks a lot, indeed had to change output in asound.conf.
As I wasn't using the hdmi output, but the headphones, it had to be changed.

Thanks again,
Steven

Hello,

mplayer is indeed working as root.

But trying to listen with vlc (with a regular user) gives me

Code Select Expand

Audio output failed:
The audio device "default" could not be used:
No such file or directory

While starting Mixer (I just installed xfce desktop) gives me :

Code Select Expand

GStreamer was unable to detect any sound devices. Some sound system specific GStreamer packages may be missing. It may also be a permissions problem.

mplayer giving :

Any ideas where rights have to be settled?

[wsteven2]

My user had to be in the audio group. Solved a bunch a weird acting stuff (like youtube not playing videos...).
