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.
