For the T570, I seem to have resolved the issue by installing the HDA DKMS driver from the ALSA Daily Build Snapshots here:
https://code.launchpad.net/~ubuntu-audio-dev/+archive/ubuntu/alsa- daily/+packages Since I'm on 18.04, I grabbed the latest "daily" DKMS snapshot, which as of this writing is from 2018-08-05. You must use DKMS to install this driver. Instructions are here: https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS The article is a little outdated, but the instructions still work. After rebooting, I had good quality sound through my ThinkPad's main built-in speakers again. I hope this helps! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1762314 Title: Sound output too low To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1762314/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
