No sound Lenovo T440s

Hello!

I've installed Hydrogen and I can't get my sound working. I maybe have a problem like this one: https://forums.bunsenlabs.org/viewtopic.php?id=1764

mike@taz:~$ volti

I've been trying all morning to switch my default sound device but no luck so far!

I tried getting a new kernel from backports but that broke Virtualbox, I then hosed everything else trying to fix VB so I'm back to a fresh install.

On Fedora I can do a 'dnf history list' then a 'dnf history rollback X' to fix my screw ups, is there a similar command for apt-get?

Anyways, I'm stuck so any help would be appreciated :-)

Re: No sound Lenovo T440s

But this into /etc/asoundrc:

defaults.ctl.card 1
defaults.pcm.card 1
defaults.timer.card 1

This establishes card 1 (the card driving line-out and the speakers) as the default card. I do also have a Haswell Thinkpad (x240) and it only worked well with kernel >4.0. Before that, I had issues with battery lifetime, backlight control and the like. So you probably need the backports stuff.
