Re: Enable docking station speaker jack for new Lenovo Thinkpads

[Mario <anyc@hadiko.de>]

Hi Phil,

I've managed to get it working with hda-verb only, so just execute the
following commands:

./hda-verb /dev/snd/hwC0D0 0x1b SET_PIN_WIDGET_CONTROL 0x40
./hda-verb /dev/snd/hwC0D0 0x1b SET_AMP_GAIN_MUTE 0xb000

Although the sound is better when choosing the second Audio Mixer. I
will take a closer lock at this.

I wrote a "little" blog entry and pushed a script on github. Both can
be found here:

https://github.com/anyc/toolsnstuff/blob/master/gentoo_thinkpad_t530/enable_docking_hp_jack.sh

Hope this helps!

Best regards,
Mario
