Re: [Alsa-user] nm256: Dell Inspiron 3500 laptop

[J. M. a. C. C. <mc...@sp...>]

Thanks for your reply.

I have now tried snd-nm256, snd-opl3sa2, snd-cs4232, snd-cs4231, =
snd-sb16,
and snd-ad1848 with this hardware (Dell Inspiron 3500, Neomagic NM2200
MagicMedia 256AV).  So far no joy!

snd-nm256 seems to come closest to working.  If I set force_ac97=3D1, =
the
module loads with the encouraging dmesg output:

nm256: Mapping port 1 from 0x2709a0 - 0x27ec00

And aplay /home/family/wavs/curly.wav gives:

Playing WAVE '/home/family/wavs/curly.wav' : Signed 16 bit Little =
Endian,
Rate 44100 Hz, Stereo
aplay: pcm_write:1265: write error: Input/output error

...close, but still no sound.

snd-opl3sa2 results in:=20

FATAL: Error inserting snd_opl3sa2
(/lib/modules/2.6.18-4-686/kernel/sound/isa/snd-opl3sa2.ko): No such =
device

unless I add some options in /etc/modprobe.d/sound:

alias snd-card-0 snd-opl3sa2
alias sound-slot-0 snd-opl3sa2
options snd-opl3sa2 fm_port=3D-1 midi_port=3D-1 port=3D0x370 =
wss_port=3D0x530
isapnp=3D0 dma1=3D1 dma2=3D0 irq=3D5

(These options were chosen by running alsaconf -> legacy ISAPnP -> probe
opl3sa2)

I have also tried

options snd-opl3sa2 fm_port=3D-1 midi_port=3D-1 port=3D0x370 =
wss_port=3D0x530
isapnp=3D0 sb_port=3D0x220 dma1=3D0 dma2=3D1 irq=3D5

Which is closer to what I have set in the BIOS.

With these options, the module loads, but I get the following dmesg =
output:

pnp: Device 00:0c activated.
ALSA
/usr/src/alsa/alsa-driver-1.0.14rc4/isa/../alsa-kernel/isa/opl3sa2.c:637:=

snd-opl3sa2-pnpbios: probe of 00:0c failed with error -16

An attempt at aplay gives=20

--------------

snd-cs4232, snd-cs4231, snd-sb16, and snd-ad1848 all behave similary.  I =
get
som options by going through the legacy ISAPnP section of alsaconf, =
loading
seems to proceed without incident, but an attempt at aplay results in =
the
same set of "no such device" errors.

Incidentally, in the BIOS I've selected custom audio settings with the
following values:

SB I/O Address: 220
WSS I/O Address: 530
Adlib I/O Address: 388
Interrupt:  IRQ5
1st DMA Channel: DMA 0
2nd DMA Channel: DMA 1

Does this list of parameters give any clue as to which chip I really =
have?

Another clue:  When I run alsaconf and it searches for sound cards, it =
finds
both the nm256 and the opl3sa2 - strange?

Much obliged for further troubleshooting help!
