When i try :

 speaker-test -D default:PCH -c2

speaker-test 1.0.28

Playback device is default:PCH
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 2048 to 16384
Period size range from 1024 to 1024
Using max buffer size 16384
Periods = 4
was set period_size = 1024
was set buffer_size = 16384
 0 - Front Left
 1 - Front Right

I hear sound, but i cant found to make it the default output.

I've tried to change /usr/share/alsa/alsa.conf :

...
defaults.ctl.card 0
defaults.pcm.card 0
...

to

...
defaults.ctl.card 1
defaults.pcm.card 1
...

and I've tried to make a .asoundrc file in my home :

pcm.!default {
    type hw
    card PCH
}

ctl.!default {
    type hw           
    card PCH
} 

doesn't work either, what am i doing wrong ?
Thanks in advance,

Re: cannot set default sound card properly

Ok, after a lot of try-and-error-and-reboot, i found that the default card is correctly defined ("aplay test.wav" works), but others applications (vlc, chromium) still did not produce sound.
Apparently, the problem came from pulsaudio, after i removed it, everything seems to work (sound is back on vlc and chromium), not sure what the problem with pulseaudio was.
