bookworm No printer, No sound

[Thomas George <debianlist@mailfence.com>]

nmap finds printer ,printer ip lan address. with lan address printer's 
state can be read and test page printed

Cups can install printer with a long ipp address, not wifi. Only the 
lpinfo command works, the others are deprectiated, not working so it  is 
not possible to set an lp destination.

xsane finds no devices

gnome settings sound finds output device Speakers - Built-in audio

pulseaudio volume port shows Speakers (plugged in)

Both these show a fluctuating signal when mpv plays an audio file but 
speakers are silent

uname -a shows Debian 6.1.0-amd64 (2023-12--2) This does not change 
after update and dist-upgrade.

Any comments welcomed,

Tom George
