My laptop (Acer Aspire 7738g) has two front speakers and LFE speaker, but as default sound come only from front speakers
When I change in /etc/modprobe.d/alsa-base.conf the following line:
options snd-hda-intel model=acer-aspire-6530g
LFE speaker is working, but only left channel is played on it.
This would be enough, but internal microphone and auto muting speakers when headphones are present stops working, which is strange, because that was working on previous version of Ubuntu.
I can also change with this:
options snd-hda-intel model=acer-aspire-7730g
And when I chose 5.1 speakers configuration LFE speaker is working as front-center speaker, but still microphone and headphones are broken.
Any chance to fix my problem?
