Hi, I've been having a frustrating couple of days getting IR to work on my
brand new Audigy2 drive... Lots of people seem to have it working, but for
me, it refused. Enabling it under windows showed that the IR _did_ work, and
if I rebooted immediately into linux, IR worked there too (although not after
a power cycle).
It turns out the Audigy2 (and maybe the Audigy as well? I don't know) has a
different port (A_IOCFG instead of A_HCFG) for accessing the GPIO
registers... This is actually in the OSS driver, but hadn't made it across to
ALSA. I assume the people who had this working were all using the OSS driver.
I'd like to point out that I've only done this for the IR.. it might be an
idea to check the ALSA emu101k source for other occurences of this for the
Audigy2..
Here's a patch against CVS to the IR enabling code.
