Raspberry Pi OS 12 (Bookworm) released

[Tim Curtis]

Couple things I noticed yesterday regarding HDMI ports (Pi-4 / 64bit Bookworm Lite)

1. No tvservice binary

Code:

pi@dev64-bk:~ $ which tvservice
pi@dev64-bk:~ $

2. HDMI device names different from Bullseye

Code:

pi@dev64-bk:~ $ aplay -l
**** List of PLAYBACK Hardware Devices ****

card 2: vc4hdmi1 [vc4-hdmi-1], device 0: MAI PCM i2s-hifi-0 [MAI PCM i2s-hifi-0]

3. HDMI devices show no mixer controls

Code:

pi@dev64-bk:~ $ amixer -c1
pi@dev64-bk:~ $
pi@dev64-bk:~ $ amixer -c2
pi@dev64-bk:~ $
