Now this I wouldn't have guessed from everything else I've read. # mknod /dev/dsp2 c 14 35 # mknod /dev/dsp3 c 14 51 # dd if=/dev/dsp2 | od -i works as expected. Very many thanks.

In fact, looking at the kernel sources, there is a #define of a max of 5 cards. So you can drive 5 cards with one instance of the driver. Don't try to load another copy, and see if your cards work (/proc/sndstat and similar). -- Juan Antonio Magallon Lacarta mailto:[EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

From [EMAIL PROTECTED] Mon Oct 23 17:18:13 2000 where can I look to find what hardware to look for/avoid? The es1371's are especially rock solid stable.

I have an es1370 (1 card) # es1370 card alias sound-slot-0 es1370 alias sound-slot-1 es1370 Quite correct, as Juan Magallon also pointed out. sound-slot-1 is used by /dev/dsp1 (the card, like yours, has 2 dsps) What you should do is add sound-slot-2 and 3 in there with the same module ... Just remember, /dev/dsp and /dev/dsp1 are the dsps of your first found card, /dev/dsp2 and /dev/dsp3 are the dsps of your second found card.
