For me the same error: the internal microphone is not recognized. I have an Acer Aspire VN7-572G-56VP with ALS255.
An external headset works when I write in the file: '/etc/modprobe.d/alsa-base.conf' the following entries: 'options snd-hda-intel model = dell-headset-multi' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1523100 Title: Alsa not detecting internal microphone [ALC255] (Realtek) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1523100/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
