Dopo una nuova installazione su un nuovissimo HP Probook 470 G3, tutto funziona perfettamente solo con l'audio :-( Prova a reinstallare tutte le parti alsa, ma ancora nessun suono.
Se il manuale è corretto, si tratta di una Conexant CX7501
Alsamixer mostra solo spdif (3x) tutto su 0. Non riesco a selezionare altre schede audio. Mi sembra che manchi i driver (intel)?
alsa-info sembra oke .. cosa mi manca?

Questo potrebbe essere il problema:
dmesg | grep snd

Ho aggiunto acpi = off a grub:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" acpi=off
update-grub
Pavucontrol installato
rimosso alsa-base.conf e riavvio
aggiunto
options snd-hda-intel enable_msi=1
su /etc/modprobe.d/alsa-base.conf
