[PATCH] alsa-1.0.24 realtek hda codec patch

Hello,

maybe you do not know but Realtek has in download section its own alsa 
1.0.24 source package with additional code for Realtek codecs.
Because this code has almost zero chance to reach end users because 
everyone uses vanilla alsa from alsa site or from kernel.org or alsa from 
distro package I thought it would be good to exctract it and put it here 
for inclusion in mainstream/kernel alsa. This way all users will benefit 
from it and code will not be wasted. The attached patch contains cleaned 
up diff between: alsa-driver-1.0.24.tar.bz2 from alsa-project site and 
LinuxPkg_5.16rc12.tar.bz2 dated 2011/4/28 from realtek.com.tw site.

Its strange that Realtek cooks this in silence instead posting it to alsa 
for everyone. I hope Realtek will have nothing against merging these 
changes mainstream. This way Realtek hardware will be better supported by 
Linux distros.

have a nice day,
Zbigniew Luszpinski

Greetings,

Can {ou tell if they have added support to use all the Output DACs ? 
or is that just not supported in the generic ALSA code ?

Thanks !

Don't worry, usually Realtek guys sync with the upstream occasionally,
once or twice per kernel release, and send us the patches.  You can
see the author in each commit of sound/pci/hda/patch_realtek.c in
kernel git tree.

It pretty depends in the codec driver implementation.
