Hello,
I am trying to get the nm256 driver to work on a Dell Inspiron 3500 laptop.
It seems I am not alone with this issue (see posts from Ted To 2007/03/05
and Matt Gushee 2006/10/23). Using force_ac97=1 I can get everything to
load, but an attempt to play a wav file gives the following error message:
Lappy366:~# aplay /home/family/wavs/curly.wav
Playing WAVE '/home/family/wavs/curly.wav' : Signed 16 bit Little Endian,
Rate 44100 Hz, Stereo
aplay: pcm_write:1268: write error: Input/output error
I am running a 2.6.18 kernel as provided by the Debian etch distribution (as
of 4/07). The ALSA driver version is 1.0.12rc1. lspci | grep audio reports:
01:00.1 Multimedia audio controller: Neomagic Corporation NM2200 [MagicMedia
256AV Audio] (rev 12)
I have also tried loading snd-cs4232 and snd-ad1848, as suggested by various
Googlings, but I always get "No such device" in response.
My /etc/modprobe.conf file has one line:
options snd_nm256 force_ac97=1
lsmod | grep snd yields:
snd_opl3_lib 9920 0
snd_hwdep 8836 1 snd_opl3_lib

force the driver to load by passing in the module parameter
force_ac97=1
or try sb16 or cs423x drivers instead.

Considering that several of us have this problem with this hardware, it
seems like this may be a bug in the driver, or rather another workaround
that needs to be incorporated. I have tried the other patches like
reset_workaround, reset_workaround2, and vaio_hack, just to see if they
might help, but no luck. I am more than willing to try things out on my
hardware to help solve this problem, if anyone wants to tackle this.
Thanks,
Jabez
