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:

Code:
groups <username>


Where <username> should be the name you log in with. For example when I run it it looks like:

Code:
groups jeff


Post the output here from that command.

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

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

I hope that includes hearing videos?

a google suggests

ftp://218.107.247.58/arm/freescale/mx51 ... _linux.pdf

actual file=SGTL5000.pdf

Chapter 18 details kernel menuconfigs for compiling

based on this output

Quote:
aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: imx3stack [imx-3stack], device 0: SGTL5000 SGTL5000-PCM-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: imx3stack_1 [imx-3stack], device 0: cs42888 cs42888-0 []
Subdevices: 1/1
Subdevice #0: subdevice #0

arecord -l
**** List of CAPTURE Hardware Devices ****

card 1: imx3stack_1 [imx-3stack], device 0: cs42888 cs42888-0 []

Please ignore download link if not a match

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.
