I tried to reproduce the issue also with the integrated headphone amp,
just to find out that my board design has an issue (oops!) - the
headphones' ground is connected to the power supply ground instead of
the virtual ground, so I can't test the VAG ramp fix this way. So I can
only speculate that you tested your fix on a properly wired headphone
output, and that's where it worked OK.
I tested on headphone output on a mx28evk.
Here is a better link to the patch:
https://git.kernel.org/cgit/linux/kernel/git/broonie/sound.git/patch/sound/soc/codecs/sgtl5000.c?id=c251ea7bd7a04f1f2575467e0de76e803cf59149
The previous one only showed the change to sgtl5000.c.
Thanks. But now I don't understand the logic of this patch. Here's the
prototype of the helper function:
int snd_soc_update_bits(struct snd_soc_codec *codec, unsigned int reg,
unsigned int mask, unsigned int value);
3rd argument is a mask, and you're passing there SGTL5000_SMALL_POP,
which is now 0.
Does the problem also happens on 3.19-rc5?
Can't use mainline for this specific project, as I need VPU support.
Kind regards,
Nikolay
