Thanks. Since the embedded patch is broken (likely due to your MUA), I applied it manually now. Check it later whether it's OK.

Thanks. Since the embedded patch is broken (likely due to your MUA),
Oh heck! sorry about that.
i did cut n paste it into opera. i attempted to do the git-patch thing from the alsa wiki and i couldnt generate a patch.
i will attempt to figure out how to use git correctly for my next patch for ac97 7.1 infrastructure.
I applied it manually now. Check it later whether it's OK.
when is later? doesnt need to be exact. rough estimate is fine.

01 Unmixed Output
10 Line In
11 Mic In
- Special Case of 00:
OUT_0 Mixed Output
OUT_1 Reserved
OUT_2 Reserved
- I have no idea what the hell Reserved does, but on an MSI
- CN700T, i have to set it to get 5.1 output - YMMV, bad
- shit may happen.
- If other chips use Universal Audio Jack, then this code might be
applicable
- to them.

Thanks. Since the embedded patch is broken (likely due to your MUA),
Oh heck! sorry about that.
i did cut n paste it into opera. i attempted to do the git-patch thing from the alsa wiki and i couldnt generate a patch.
i will attempt to figure out how to use git correctly for my next patch for ac97 7.1 infrastructure.
I applied it manually now. Check it later whether it's OK.
when is later? doesnt need to be exact. rough estimate is fine.
Usually it appears within a few minutes :) My git tree is found at git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git
Gitweb is http://git.kernel.org/?p=linux/kernel/git/tiwai/sound-2.6.git;a=summary
