Re: sound on PowerBook G4 and iBook G4

Hi Stefan

Yep, I sent it in an informal way to linuxppc-dev just to see if I could get some feedback on it (having seen that you had had no reply on the debian list). I'd like to get it included in the next Ubuntu release, so I was trying to get somebody to comment on it. It seems an incredibly simple patch!

As you've probably seen I've had no reply. Perhaps if you send it in formally and sign it off you may get a better response? As far as I can tell, the last patch from May 2013 just got forwarded to the alsa-devel list and they included it.

My own good iBook died this week. 2 hours of compiling the kernel maybe was a little too much for it. Sigh.

I must admit that I have no idea if my patch correct, I was hoping to
get some feedback on it by first sending it to debian-powerpc. Besides,
you seem to have already forwarded my patch to linuxppc-dev.

You're right, the iBook only has a headphone jack. I no longer have one,
so I cannot test if your change works.
