[0319A13, Realtek ALC269, Speaker, Internal] Pulseaudio fails to detect card

[Guillaume Romagny]

I have lost ALC269 sound between ubuntu 14.04.1 and 14.04.3
and probably switch from kernel 3.13 and (3.16-3.19)

Sound (speakers) was working fine since 2011 with Ubuntu.
Knoppix 7.4.2 (32bit), the sound is working fine.

lsmod/lspci give (almost) the same output (more kernel mod for ubuntu/intel hda)

The main effect is I only see a "virtual output", no speaker

I am unsure if thinkpad_ec module may interfere now (and not in the past)

[Guillaume Romagny (golfromeo.ovh)]

from time to time, the following command works (speakers appears in ubuntu config, then only fake output is left)

sudo alsa force-reload

so I only see "dummy output"

I have blacklisted thinkpad_ec,thinkpad_acpi,tp_smapi but it doesn't change anything
