Dear all,

I'm on Debian 11.2, pretty much up to date.  I have a mystery with sound
that I cannot resolve.  I have according to lspci the following audio
devices:

00:1b.0 Audio device [0403]: Intel Corporation C600/X79 series chipset High Definition Audio Controller [8086:1d20] (rev 06)
02:00.1 Audio device [0403]: NVIDIA Corporation GK107 HDMI Audio Controller [10de:0e1b] (rev a1)

Pulseaudio only finds the second of these (speakers in an attached HDMI
monitor) which is fine for much of my use.  However, it means that I
cannot use headphones plugged in to the box.  Alsa lists all the
devices:

$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC3220 Analog [ALC3220 Analog]
card 2: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
card 2: NVidia [HDA NVidia], device 7: HDMI 1 [HDMI 1]
card 2: NVidia [HDA NVidia], device 8: HDMI 2 [HDMI 2]

but pulseaudio only shows the HDMI interface.  

Any hints on getting pulseaudio to find the Intel device would be
welcome.

Thank you,
eric
