[Aspire one, Realtek ALC272X, Green Headphone Out, Left] No automute

[Raz Ziv]

The internal speakers do not automatically mute when headphone is plugged in.
Also, not all sound is played on the headphones:
1. When changing the volume through the laptop (AAO D150) keyboard, only the internal speakers give the feedback.
2. When clicking a raio button on the apport interface, bot headphones and internal speakers produce the feedback sound, but when changing radio buttons with the keyboard, only the internal speakers give the feedback sound.
I've tried adding the following lines to but no option has worked:
- options snd-hda-intel model=acer
- options snd-hda-intel model=acer-aspire
- options snd-hda-intel model=acer-aspire position_fix=1
- options snd-hda-intel model=acer-aspire position_fix=2
Also, the headphones jack does not appear as an output device in "sound settings".

I would try the latest driver to make sure it has not already been fixed upstream: https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS

[Raz Ziv (raz-ziv)]

Thanks, Daniel. The latest driver did not solve the issue. After installing it, I tried again changing /etc/modprobe.d/alsa-base.conf, but the problem remains.
