Just a thought, but is it an Awe64 Value? If so, the ram is only 512k. I seem
to
remember somewhere in the distant past something about the Awe driver sometimes
not
getting the ram size right.
This part you uncommented -
#define AWE_DEFAULT_BASE_ADDR 0x620 /* base port address */
#define AWE_DEFAULT_MEM_SIZE 4096 /* kbytes */
Try replacing the 4096 with 512?
Unless you are sure you have 4096k..... otherwise, I'd suggest trying the
latest kernel
(2.2.13), or at least a newer one that comes with 0.4.3 Awe drivers built-in.
Probably not related, your isapnp.conf settings look OK but I had to put a line
(VERIFYLD N)
above the readport part at the top.
***Ah, having read your dmesg output (properly, this time!), I think I can see
what the
problem is. You've compiled the AWE driver straight in to the kernel. For an
isapnp
card, you have to do ALL of the sound stuff as modules - including the
low-level one and
the Awe driver. Then run modconf to load them, passing the correct parameters
to each
(only sb and opl3 modules need parameters).
Tacking on the Awe driver to the 2.0.whatever kernel that comes with Debian is
not ideal,
get the latest kernel and use it.
