The output was what you would expect, lots info about HDA drivers and
hardware:
lspci -vnn | sed '/Audio/,/driver/!d'

However, grepping dmesg was interesting:
# grep HDA /var/log/dmesg

No output about the speakers. On another system (that works) I see:

I think Line Out is a speaker. So why the difference?
Thanks
