I have currently no sound. It is an ASROCK N3050B-ITX motherboard with onboard sound with the following specifications:

Missing drivers? Which?? Very little sleep last night is probably not helping. But my husband wanted this emergency computer fast so that he could keep up with his courses - and for that he wants sound. :-(
