This is probably related; I haven't actually tested yet, but I have
one more information: I had "model=lenovo" in modprobe configuration.
This was necessary because otherwise the driver applied the quirk for
Asus G1, resulting in no sound (see bug
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3513).
The driver works fine without "model" parameter (possibly due to the
removal of the quirk entry for the the G1); I get a warning about a
timeout when MSI is not enabled though:

HDA Intel 0000:00:1b.0: PCI INT A disabled
HDA Intel 0000:00:1b.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22
HDA Intel 0000:00:1b.0: setting latency timer to 64
hda_codec: ALC660-VD: BIOS auto-probing.
input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1b.0/input/input9
hda-intel: azx_get_response timeout, switching to polling mode: last
cmd=0x018f0900

Will do a compile test ASAP.
