WM8731L codec, low volume and sound distortions

<< < (3/3)

lowlight:
Update: while I haven't found the missing gpio bit for the sound, I think I understand how to operate the touchpad.

lifeless:
Wow, and how?
I know there is something like serial interface, but on gpios. And have not found the right way.

lowlight:
It appears the missing bits are:
GPO32_ENABLE |= 0x2;
GPO32_VAL &= ~0x2;

Try adding that to WM8731.c in audiohw_postinit().

I haven't done the commit yet because my dev maching at home is down.

lifeless:
That works great!

Does it turn on preamp in wm8731 or another one? And how did you found this bit? I have searched in OF disassembly now and have not found any mention about bit 2 for GPO32.

UPD: I have posted a patch for lcd contrast/brightness changing in the same patch FS#9591.
