Howdy Folks,

Currently working at getting functional audio under Debian Testing on the Smartbook. Any tips for where I should start looking? Alsa is not finding any audio devices with my current setup.

I've got the snd_soc_imx_3stack_sgtl5000 module loaded, but still no dice. Any thing else I should have?

EDIT: Adding myself to audio group appears to have done the trick.

Hei everibody,
I've installed armhf-2G on nand memory by coping it from SD card and all runs well but sound.

I've installed alsa with apt-get install alsa,

with # lsmod | grep snd
I get: snd_soc_imx_3stack_sgt5000; snd_soc_imx; snd_soc_imx_ssi; snd_soc_sgtl5000

with # aplay -L
I get:
default
Playback/recording through the PulseAudio sound server
pulse
Playback/recording through the PulseAudio sound server

with # alsactl init
I get:
Found Hardware: "SGTL5000" "" "" "" ""
Hardware is initialized using a generic method

I'm using 2.6.31.14.25-efikamx kernel, uname dixit.

I don't know what can I do! Somebody can help me?
thanks in advance

Crack open a terminal and run:
Where <username> should be the name you log in with. For example when I run it it looks like:
Post the output here from that command.

I 've added myself to group audio but no luck with it.
May be I need some more group?

with groups aleix
I get: aleix: aleix sudo audio

thanks

Can you remove pulse audio, restart, and then run amixer in terminal to see if it shows any output devices?

~Jeff

It's OK!
I've purged the package pulseaudio and after restored it runs, I can play music and see videos. When I run aplay -L the default CARD is imx3stack.
Thank you

Aleix Orti writes I hope that includes hearing videos?

Yes I know you have sound but suspect you may prefer to re-compile a vanilla kernel.

I've been struggling with a weird sound problem on armhf + alsa for some time and I had hoped that the problem would just go away with this new armhf image but no.

I've got the smartbook hooked up with a pair of active speakers and for some reason the left channel is substantially lower in volume than right. I can't find anything related to balance or channel specific volume setting in alsamixer.

Obviously I've quadruple-checked the connections and can't find anything physically wrong with this setup. Not to mention that the setup works as it should with other devices connected -- even with the same cable.

I do not believe in a devil, but if I did, PA would be proof that the devil was a programmer, and PA was sent to us straight from hell. :)
