[alsa-devel] Bug report for: [P7xxDM2(-G), Realtek ALC898, issue: Headphone Jack, External] No sound at all

[Dennis Mungai]

Hello there,

To override the pins, I used a method similar to what hdajackretask
does, which is to write a firmware patch, as shown below:

The second action, dac_fixup, is a two-step process, inferred from the
actions.py subroutine:

(a). Create a /lib/firmware/clevo-audio-patch with the following entry:

[codec]
0x{vendor_id:08x} 0x{subsystem_id:08x} 0

[pincfg]
0x1b 0x01111060
0x19 0x23A11040

[verb]
0x1b 0x707 0x0004

(b). Create an /etc/modprobe.d/clevo-alsa-base.conf file with the
following entries:

 options snd-hda-intel patch=clevo-audio-patch

Then reboot the system. Confirm the successful override by grepping
dmesg on boot:

 dmesg | grep clevo

Here are my pin configs:

sudo cat /sys/devices/pci0000:00/0000:00:1f.3/sound/card0/hwC0D0/init_pin_configs

list:

0x11 0x4004d000
0x12 0x90a60140
0x14 0x90170110
0x15 0x411111f0
0x16 0x411111f0
0x17 0x01011050
0x18 0x01a11030
0x19 0x411111f0
0x1a 0x0181103f
0x1b 0x411111f0
0x1c 0x411111f0
0x1d 0x40350d29
0x1e 0x01441120
0x1f 0x411111f0

As at the moment, I'm running the latest kernel available to Ubuntu 16.04LTS.
