Well, what kind is your soundcard? Notice that the kernel soundmodem (the module you're trying) only supports Sound Blaster o Windows Sound System compatible cards. Many new cards are not suported by it. But haven't you heard about the userspace soundmodem? It is not a kernel module, it's a usermode program, it's easier to configure, and (the most important thing) it handles the soundcard through OSS, so it works with virtualy every soundcard supported by OSS. > How can I verify what the IO, DMA and IRQ of the sound card is, > if > it is built into the motherboard, and the BIOS offers now way to > set those for the card? > > Other than the soundcard not being set right by sethdlc, I am > lost > as to what is wrong.
