Omnibook900, Neomagic NM2200 256AV and ALSA problems
I'm using an old HP Omnibook 900 for playing and poking around.
I've installed Debian 3.1 with the latest 2.6.11 kernel and am trying to get
any sound out of the box, since I remember having heard sounds
on a previous old Linux setup - kernel 2.2.x and OSS stuff.
0000:01:00.1 Multimedia audio controller: Neomagic Corporation NM2200 [MagicMedia 256AV Audio] (rev 20)
Neomagic Corporation NM2200 [MagicMedia 256AV Audio]
So I have an Neomagic 256AV chip which doesn't seem to be working
with the snd_nm256 module. ALSA does not give me any sound. Alsaconf says it finds "nm256" and "Legacy" of which the first one goes through the pass fine, Legacy (as nm256 is a PCI chip trying to emulate legacy ISA stuff) doesn't work at all.
alsamixer: function snd_ctl_open failed for default: no such device
In the kernel boot messages (dmesg |grep -i nm256) I get the following error:
nm256: no ac97 is found!
force the driver to load by passing in the module parameter "force_ac97=1" or try sb16 or cs423x drivers instead.
NeoMagic 256: probe of 0000:01:00.1 failed with error -6.
There are no such modules provided with ALSA (at least in the kernel packaged version) and forcing the mod parameter doesn't work either.
Any ideas? Do I need to install OSS to get any audio?
