Re: List archive broken / H5450 headphone socket

Ross,
  ...just a helpful hint -- that program won't do it as written: you'll get
some kind of error back (bad value or bad argument or somesuch) -- the
ioctl won't take a constant as the last argument. You'll have to do
something like :

unsigned int value = SOUND_MASK_LINE;

and

 ioctl(fd, SOUND_MIXER_WRITE_RECSRC, (void *) &value);

for it to work.
