[alsa-devel] Applying Herton supplied patches ...

[Guy Stalnaker]

herton or Takashi,

How does one go about applying a patch like the ones attached to Message 
6?  And to which files are they applied?  I assume they are meant for 
the alsa-driver code, but that's as much as I know (well, I know how to 
run ./configure, make, and make sudo :).  I'd very much like to see if 
the patches work for my HP dv4 1225.

Regards,

Guy
