SuperMicro server board being used as workstation.
Board has no audio itself.
I have USB headphones I sometimes plug in.
Unfortunately every time I plug them in I have use to use audio control panel and choose them. Why?
lspci |grep Audio
01:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1)
lspci -n |grep “^01:00.1”
01:00.1 0403: 10de:0be3 (rev a1)
Seems the cheap nVidia 405 card I have installed has an audio controller
(Interestingly reported as Intel HD Audio by the sound control panel)
which I guess it has because of the HDMI interface.
Is there a way to tell the sound system to pretend that controller isn’t there? I will never need audio over the HDMI.
