hi everyone,

how is the status now with the headphone jack for H5400? how is it possible to
set the line-out to work and to disable the speakers without any mixer gui?
(taken one already has the patched ak4535.o module)
the below code sniplet didn't work because of:
ioctl: switch to headphones out: Bad address

where do I find more details about the possible ioctls for this device?
SOUND_MIXER_WRITE_RECSRC, SOUND_MASK_LINE and so on?

thanks!

Mike
