Description Guillaume APOSTOLY 2002-07-15 09:04:04 UTC

I've got an IBM netvista with an intel onboard chipset that deals with network, 
audio, etc.
The audio driver needed is the i810_audio (ICH2) along with the ac97_codecs.
I've tested them compiled in the kernel or as a module and i'm getting the same 
With the drivers as modules, the insmod of ac97_codecs and i810_audio seem to 
work fine and they're correctly linked together when i do an "lsmod".
Still : "cat something.wav > /dev/dsp" gives nothing and when I start KDE, i've 
got a message saying "sound server error : cpu overloaded".
I've read messages on the net and on some newsgroups saying that this was fixed 
in 2.4.18 kernel. I'm using the 2.4.19-gentoo kernel, maybe this issue is 
distribution specific.
I'm ready to test stuffs if needed.

Try this in mjc-sources. Sorry for the slow response..
Comment 2 Guillaume APOSTOLY 2002-07-17 02:45:01 UTC
What are mjc-sources ? a replacement to the kernel gentoo-sources ?

ps: was not so slow ;o)
Comment 3 Guillaume APOSTOLY 2002-07-17 07:15:10 UTC
Ok, i'll give a try with the sys-kernel/mjc-sources-2.4.19_rc1 package.
But what is the relation betwenn the gentoo-sources and the mjc-sources ?
Comment 4 Guillaume APOSTOLY 2002-07-17 09:31:53 UTC
- Same problem with sys-kernel/mjc-sources -
I've installed the mjc-sources kernel and recompiled it, after rebooting using 
this kernel (uname : ) i've got the same problem when launching KDE (sound 
server overload).
I didn't try to cat something.wav into /dev/dsp (because i installed the new 
kernel at home via internet from my office and ... i can't ear the sound 20kms 
away ;o) but i guess it does nothing...
Another idea ?

ps: still, i'm happy to have this last kernel :o))

I found out that on my IBM, the codec chipset used along with the i810 is the
new SoundMax codec. This is a codec that provides better sound quality than the
old ones but ... that seems, not to be supported under linux !
I've looked a little on the net, found people having the same problems, and no
clues to write the driver.
I think we should close this bug though i'm no sure it's not gentoo related.
Sorry for the mess ...

I'll perhaps look for the AC97_codec module's maintener for support ...
