Linux can''t seem to detect my ISA PnP Ess688 sound card. modprobe sb io=0x220 irq=5 dma=1 esstype=688 fails with the msg: device not found. The sound card works under windows and my hw settings are correct. Does anyone know what seems to be the problem?

Try to disable "Plug and Play OS" in your BIOS. It might be the cause of your problem.

Hope this helps.

Tried that. Didn''t work. isapnp is able to detect the device
on kernel bootup, but then any attempt to init the dsp fails.

This is a stupid question, but have you checked if you have a /dev/dsp device? Also check your logs, you''ll probably find more infos in there.

Sorry if I can''t help but if you know the IRQ, DMA etc I don''t understand how it could fail, unless the device wasn''t created.

Yeah I do. But I don''t see how having /dev/dsp or not actually
matters since you had to insmod or modprobe the module first
before you could use the node.

My logs don''t really give anything helpful. If I had PnP enabled in the BIOS, card detection is successful but dsp initialisation
fails during bootup. Either way, when I try to modprobe sb,
it would fail with ''No such device''.

Just to add on to other suggestions, try 'modprobe -a sb'. After reading some docs in /usr/src/linux/Documentation/sound/ about my own sound card I learnt that certain modules depend on other modules. For example, my laptop has a yamaha soundcard, but to load that module, i need to load several modules (soundcore, sound, mpu401,ad1848, opl3sa2).

Use the 2.4.x series kernel, load sound as a module and include all those modules which you think would include your soundcard.

If that don't work, give alsa and OSS a try.

I''ve never tried with an ESS card, but I know with my ISA sound blaster, I have to use pnpdump and make an /etc/isapnp.conf file.

Once that is done, I run isapnp, then modprobe. Once it all works, I make sure that isapnp and the right modprobe info are in the rc files.

You might check out:

man isapnp
man isapnp.conf
man pnpdump

Hope that helps.
