Multimedia :: Soudblaster Vibra 16 (sb)



Hello!
Recently I installed Damn Small Linux 8.0.0 on my AST ASCENITA950N laptop. It runs fine on it, but sound doesn't work.

sndconfig doesn't find any cards, and when I select the card, it exits with the error message segmentation fault

when I try
Code Sample

$ insmod sb
/path/sound/sb.o: unresolved symbol sb_dsp_init
/path/sound/sb.o: unresolved symbol sb_dsp_detect
/path/sound/sb.o: unresolved symbol sb_dsp_unload
/path/sound/sb.o: unresolved symbol smw_free
/path/sound/sb.o: unresolved symbol unload sbmpu
/path/sound/sb.o: unresolved symbol probe_sbmpu


anybody ever met this kind of errors? May I've got to recompile a kernel? Is there any other solution, shorter than a kernel compile?
Thank you in advance
What do you see if you type
" modprobe sb "  or even better
" modprobe sb io=0x220 irq=5 dma=1 dma16=5 mpu_io=0x330 " ?

If those commands return a prompt without errors, you can also try..
" modprobe opl3 "

If successful , exit X ( ctrl-alt-bksp ) and restart X  " startx "
Do you see the wmix dock app in yor slit ?

The sndconfig app frequently seg-faults...  not your laptops fault.
The 0.70 works better, but installs much bunk as well...
It is available thru apt-get..

Can you change the sound card parameters in your bios ?
( I thought you could on this model )
What are they set to now ? ( io , irq , dma , etc... )
Try changing the irq to 7, as yenta ide likes to grab irq5 on bootup.

Hello!

Thank you very much for your detailed answer ke4nt1!
In BIOS, these settings are changeable, but I left them at their original values.

I tried modprobe sb io=0x220 .... and restarted X.

Sound works: I could listen to 96kbps 44kHz internetradio on a pentium 75 Mhz, 16MB RAM without lags, at 75% CPU utilization!! That's great!

I only don't know, why is it a bit silent with headphones. But music sounds better with an amplifier! :) :D I should see if the inbuilt speaker is working.

I never could imagine that once this laptop will do graphics, not mentioning sound with Linux!

Another thing I would like to ask, is how do I configure DSL, so that the soundcard is recognized and set up during boot?
Add your modprobe line to your "/opt/bootlocal.sh" ..

Make sure the text  "/opt/bootlocal.sh" is in
your /home/dsl/filetool.lst ..

After you have completed a backup,
if you use the "restore=yourbackuplocation" when you boot,
the settings will automagically be restored with every boot.

If this is a HDInstall , simply edit the /opt/bootlocal.sh

And the little red dot on the circle in your wmix dock app
is your mixer settings/volume control ..
Click & Drag with your mouse ..
Check both PCM/wave volume, and master volume.
