Poor sound using HDMI on cubieboard (cubian os)

I'm using a cubieboard with cubian desktop to play video through hdmi output. (cubian is based on Debian 7.0 wheezy armhf, more info here )

the video is fine and I can hear the sound in headphones. I could switch to HDMI sound output (in vlc through : Audio > output > hdmi)

but then the sound become very noisy and I can bearly hear the video sound behind this loud noise :/

cat /proc/asound/cards output seems fine :

0 [sunxicodec     ]: sunxi-CODEC - sunxi-CODEC
                  sunxi-CODEC  Audio Codec
1 [sunxisndhdmi   ]: sunxi-sndhdmi - sunxi-sndhdmi
                  sunxi-sndhdmi

when I launch alsamixer and switch to "sunxi-sndhdmi" a message says "This sound device does not have any controls."

and I'm stuck... I don't know what to try now

does any one experienced a similar issue ?

I don't know much about sound control on debian so any comment is wellcome :)

I had the same problem and I solved creating a ~/.asoundrc in cubie and adding the next lines:

pcm.!default {
type hw
card 1 #change to 0 to use HP, 1 HDMI
}
ctl.!default {
  type hw
  card 1 #change to 0 to use HP, 1 HDMI
}

save and do a test

speaker-test -twav -c2

This is not the best way to enable the HDMI/HP but it works

Cool thank you that worked. Afaik it is also possible to move the same content to /etc/asound.conf to have the settings active system wide. – white_gecko – 2015-11-24T22:46:44.520
