Spent a little while tonight trying to figure out the sound drivers to
help pin things down, and I've managed to come up with a patch to fix my
problem..
Now, I'm not positive this is the right fix, but I'm not even going to
try and mess with the auto-detection code without having the specs for a
few of the ESS cards in front of me..
The card is detected as a 'ESS0968' by isapnp, however 2.2.0p4 (which
works fine) identifies it as
isapnp detects the card as
--START--
# Card 2: (serial identifier 35 00 00 00 01 68 09 73 16)
# Vendor Id ESS0968, Serial Number 1, checksum 0x35.
# Version 1.0, Vendor version 1.0
# ANSI string -->ESS Plug and Play AudioDrive<--
--END--
2.2.0p4 (which works fine) detects it as
--START--
Audio devices:
0: ESS ES1688 AudioDrive (rev 11) (3.1)
--END--
But, for added fun, 2.2.0p6ac2 sees it as
--START--
Audio devices:
0: ESS ES1788 AudioDrive (rev 11) (3.1)
--END--
I'm not sure which to believe, but I'm leaning towards isapnp's guess..
The mixer seems to be that of a ES1688 driver wise, including the
reclev setting..
As such I finally made the change (patch attached), sadly I'm pretty
sure that this is not %100 correct, and may break the mixer of the newly
support ESS cards with a submodel of 10 which, without this patch, would
get the 'es1688later_mix' mixer struct..
Hopefully I've managed to pin down enough for you to track down the
proper fix.. :/
If there is any more I can do to help please ask..
