Thinkpad NeoMagic sound problem
Hi there.
After a lot fo trying and failing, I ask thee - "What am I doing wrong?!"
I am trying to get my sound working on my Thinkpad 390. According to lspci
there is a NeoMagic MagiceMedia 256AV, which seems correct.
Downloaded the ALSA source and tried to compile my module.
Configuring and compiling went alright, no complaints, but when trying to
modprobe the module it fails. According to some info I found, I installed
soundcore before trying to install snd-nm256, but that didn't change anything.
When I do modprobe snd-nm256, the error says I have to have ac97 installed.
That can be forced by using modprobe snd-nm256 snd_force_ac97=yes, but that
totally hangs my computer.
It also says something about not finding the soundchip or that the device
is busy. I have tried passing parameters regarding I/O, IRQ and so forth,
as I read them from CMOS-setup, but that didn't change anything.
The INSTALL readme says that on some machines the module might hang-up
during install when autoprobing the buffer top adress. I suspect that might
be the cause of the hang-up when I use the snd_force_ac97=yes option. The
solution is to specify it manually with option snd_buffer_top, but I cannot
find out what adress that might be.
Anyone had any succes with ALSA and Neomagic 256AV on Thinkpad?
