I can confirm this. I tried to record myself speaking and it was as if everything were overamplified to the point that only distorted noise can be heard.
Lowering the mic volume helps. Setting it to "base" in puslseaudio volume control results in audible dialog with just a bit of noise in the background. Still, my voice felt too quiet, and the quality is not the best, so it's far from an ideal solution, just a workaround until a fix comes. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1769936 Title: [80X7, Realtek ALC236, Mic, Internal] Sound is distorted Lenovo Yoga 720 Status in alsa-driver package in Ubuntu: Confirmed Bug description: Happy to do further testing, fresh install of Bionic.
