hi all,
we try to make a surround 5.1 soundcard working on a SliTaz driven 12 volts Thin Client from the HP T5500 series.
although SliTaz/ALSA recognizes both cards we have it is not yet possible to get any sound out of our TC
audio is working fine on the motherboard sound-out but this is in old fashioned 2 channel stereo. for the art installation we are working on we need a 3 channel mono output.
on each channel there is a separate voice, all three channels make a nice background sound.
specs:
Thin Client: HP T5510 - 512Mb 64X64 DDR333 - 1Gb flashmod - (very smooth working)
Slitaz 3.0
1. asus xonar DX PCI 5.1 (ALSA comp)
2. soundblaster 5.1 vx (ALSA comp)
who knows how to get one of these cards working

first control if the cards are present and working with
aplay -l
then did you check the volume levels with alsamixer?
and sometime thats not enough - see a post in the old forum

thnx Kultex
i will check aplay -l for sure
alsamixer was set correctly
Offline
unhappy - - root says: aplay not found - - - ??
soundconf - -
amixer: Mixer attach default error: No such file or directory
alsactl: save_state:1502: No soundcards found..
Offline
I am not sure if aplay is part of alsaplayer or alsa-utils. You may need one of those, maybe both:
root@slitaz: tazpkg get-install alsaplayer
root@slitaz: tazpkg get-install alsa-utils
This is an interesting topic that might help:

thank you totoetsasoeur 4RE
both are already installed - -
just found out that there is no .conf file for the chipset
my card Xonar DG PCI 5.1 - - has a chipset CMI8786 HD
in the /usr/share/alsa/cards - - there are:
CMI8338-SWIEC.conf
CMI8338.conf
CMI8738-MC6.conf
CMI8738-MC8.conf
CMI8788.conf
no CMI8786-HD.conf
does anyone know how to get or modify the config file?
Offline
you have to reinstall alsa-utils - as root
tazpkg get-install alsa-utils --forced
Offline
this card is supported by snd-oxygen, which is not present in stable, but it will work in cooking
Offline
forced install done
soundconf - -
offers me only the CMI8788 drivers - no 8786 - is that correct in your opinion?
because - - card is not found
Offline
its not supported by stable - only in cooking
Offline
can i upgrade to Cooking from my stable without a fresh new install
i.o.w. can i upgrade on the command line?
i guess:
# tazpkg get-install slitaz-cooking
Offline
I would just try out the new cooking iso, before you upgrade - the soundblaster card should work without problems
Offline
i remember trying to install Cooking on the TC
had a lot errors and a total crash
don't know why
if you are interested i can reproduce it in some minutes
Offline
Cooking 20110328
after Bios - - and a little while:
Kernel panic - not syncing: Attemted to kill init!
Pid:1, comm: init Not tainted 2.6.37-slitaz #2
Call Trace:
[<c1372ca2>] ? printk+0xf/0x11
and then 13 lines with similar error codes
last line says:
[<c100384d>] ? do_invalid_op+0x0/0x80
then it is very quiet - - -

here it is described, what you have to do on stable

thank you kultex for your efforts to help on this issue
i have to conclude something you guys already know; Cooking is not useful for Thin Clients in the T5700 series. if i am not able to start-up on 3 different TC's with different BIOS versions - - but a small kubuntu will startup from USB - then there is no other reason then - Cooking is not ready yet.
so - i'll stay with stable - the important TC for the art-installation i'm working on is still running only with the wrong surround card - tomorrow change-day to a supported type the Audigy - i have to finish the job in 8 days - i have to make that decision now.
on the other hand SliTaz is working without any complains as a headless TC. unplug keyboard, mouse and screen: stable is starting-up and running.
thank you for all your patience - - - -

just a tip - I use geode machines - the best is a fujitso futro A250 on ebay or the msi fuzzi
http://cgi.ebay.com.sg/MSI-FUZZY-LX800-AMD-Geode-500Mhz-MINI-ITX-MOTHERBOARD-/200539342200
- with different sound cards as soundserver for exibitions - for 5.1 the TERRATEC AUREON 5.1 USB works fine - but you will find it just on ebay
http://cgi.ebay.at/TERRATEC-AUREON-5-1-USB-MKII-/330547543275?pt=DE_Technik_Computerzubeh%C3%B6r_Multimedia&hash=item4cf62b3ceb
if you dont need a screen the most energy efficiant sound server would be a bricked seagate dockstar (http://jeff.doozan.com/debian/)

need help again, sorry
i thought i was pretty sure that the soundcard i installed Sound Blaster Audigy SE would produce a 5.1 surround
when checking the Mplayer from the command line i discovered that mplayer downmixed the AC3 audiostream to 2 channels in stead of the 3 inside the file
screen:
Playing /home/tux/my3channel.ac3
libavformat file detected
[lavf] Audio stream found, -aid 0
==================================
Forced audio codec: hwa3
Opening audio decoder: [hwac3] AC3/DTS pass-trough S/PDIF
No accelerated IMDCT transform found
hwac3: switched to AC3 9600 bps, 44100 Hz
AUDIO: 44100 Hz, 2 ch, ac3, 96.0 kbit/6.80% (ration: 12000->176400)
Selected audio codec: [hwac3] afm: hwac3 (AC3 trough S/PDIF)
==================================
AO: [alsa] 48000Hz 2ch AC3 (1 bytes per sample)
[format] Sample format big-endian AC3 not supported
could not find matching filter/ao format
Video: no video
Starting playback
- about the pass-trough: on my soundcard i am not able to use S/PDIF - output must be analog audio
- settings in the amixer for S/PDIF is off
- volume for all channels in amixer is 70%
- the AC3 audio stream has 3 channels L - C - R
- card setting has: channels=6
is someone familiar with this phenomenon
help is much appreciated
