A few days ago i installed GalliumOS 3.0 on a lenovo n42, after that i have no sound from speakers. As default sink appears "Dummy output". I'm new at gallium, no idea what's happening.

I've got the exact same problem on REKS Lenovo N42 after Gallium OS 3 fresh install. Sound was working great with previous version. Thanks for looking at this.

I have the same issue on an Asus C223. Not sure where to go from here

I don't have machines like yours, so I probably can't help. However, lspci output is pretty useless without the -k (or -kv), and dmesg output is even better.
