Yes, that's because in the bullseye case you have used the mini.iso. As I wrote, please rather use the netinst bullseye iso image. The mini.iso image was only to check whether the presence of the i915 driver would help. > ## Output of amixer -c 0 scontents and amixer -c 1 scontents for the Bullseys > mini_amixer1contents > > > ## Output of amixer -c 0 scontents amixer -c 1 scontents and amixer -c 1 > 10.11.0_amixer1contents One thing I notice is this: Simple mixer control 'IEC958',0 Capabilities: pswitch pswitch-joined Playback channels: Mono Mono: Playback [off] It's off in the Buster case and on in the Bullseye case. I guess you are not using the IEC958 output. Could you try running this inside the bullseye installer: amixer -c 0 sset IEC958,0 off samuel
