Hello, it's me again...
OK, I guess you're saying I should concentrate on the opl3sa2 driver. I
have now blacklisted snd-nm256.
I have tried very carefully to set all the options correctly for opl3sa2,
but it still doesn't work. I am using the latest alsa package, 1.0.14rc4.
Symptoms are:
dmesg output:
ALSA
/usr/src/alsa/alsa-driver-1.0.14rc4/isa/../alsa-kernel/isa/opl3sa2.c:637:
PnP manual resources are invalid, using auto config
ALSA
/usr/src/alsa/alsa-driver-1.0.14rc4/isa/../alsa-kernel/isa/opl3sa2.c:233:
opl3sa2: can't grab port 0x0
pnp: Device 00:0c disabled.
aplay result:
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:1265: write error: Input/output error
I used lspnp -v to get the ports for the soundcard, which is device 00:0c:
00:0c NMX2210 (unknown)
state = disabled
io 0x220-0x22f
io 0x530-0x537
io 0x388-0x38f
io 0x320-0x321
irq 5
dma 0
dma 1
(this is same info as looking in /sys/bus/pnp/devices/00:0c/resources)
My /etc/modprobe.d/sound file contains:
alias snd-card-0 snd-opl3sa2
alias sound-slot-0 snd-opl3sa2
options snd-opl3sa2 sb_port=0x220 wss_port=0x530 fm_port=0x388 midi_port=-1
port=0x320 isapnp=no dma1=0 dma2=1 irq=5
The ports, dma's and irq's I've chosen definitely match those reported by
lspnp. The dmesg output shows the driver is still unhappy, and tries to
auto config (even though isapnp=no). Any suggestions?
BTW, my kernel is 2.6.18, Debian etch release.
Thanks for you patience.
