Thanks for the reply Daniel!
Well, I've patched and compiled Takashi's kernel... still no luck, no playback.
The good thing is that I also compiled this same kernel without patching and playback did work, so I assume there's something wrong with the patch I'm applying??
What I do is simply opening Audacity and trying to play a sound file. With the patched kernel Audacity says that it can't open the device for playback. I also tried jack and it won't start in playback or duplex mode.
As I said, recording does work ok.... And also, the kernel without patching works in all modes.
So... can you give me a link to the patch, just in case the patch I'm using has something wrong (although no errors are displayed when patching)
Secondly, is there a way I can debug the playback error? Some command line that could tell me why it can't open the device?
By the way, I'm in Kubuntu 10.04 and I'm compiling the kernel with kernel-package 12.036.
Sorry for being such a pain!! Thanks!!
PS: here's the output of the patching process:
