In response to another thread, I tried this, with no effect:
sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-`uname -r` linux-ubuntu-modules-`uname -r` libasound2
I have also tried rebooting cold. No luck. I am running 64 bit Mint with Cinamon 1.6 on a Lenovo T420 laptop.
What can I try next?
Thanks!
