No (analog) sound output w/ Realtek ALC269VC (Thinkpad X230)

edit

I do have a Lenovo Thinkpad X230 that has a Realtek ALC269VC sound chip onboard, Fedora 22 installed. Unfortunately, the speakers don't output any sound (while headphone jack and sound over HDMI/MiniDP works fine).

I already ran dnf reinstall alsa-plugins-pulseaudio which didn't do the trick.

alsamixer does not show anything suspicious to me. No channel is muted, no auto-mute...

I recently switched hardware and restored my entire home-dir on my new machine (including ~/.config/pulse/ and ~/.config/gconf/system/pulseaudio). Could that be the problem? What about just deleting those two directories?

Output of rpm -qa | grep alsa:

EDIT: In the meantime, I also added a model option to the kernel module by creating /etc/modprobe.d/sound.conf with the following content

options snd-hda-intel model=headset-mic vid=8086 pid=1e20

Didn't help.

EDIT2: Isn't it strange that alsactl init fails with the following output?

alsactl: sysfs_init:48: sysfs path '/sys' is invalid

Going to paste the output of `alsa-info.sh-script here - plenty of information.
