Title:
No HDMI sound output from alsa in server (no KMS)
Status in linux-raspi package in Ubuntu:
In Progress
Status in linux-raspi source package in Kinetic:
In Progress
Bug description:
During ISO testing of the beta Ubuntu Server 22.10 for Raspberry Pi
image, on a Raspberry Pi 4B and 3B, I noted that the HDMI "sound card"
no longer appears in /proc/asound/cards; only the Headphones output
(from the AUX socket on the board) appears.
I checked with the current linux-raspi in the release pocket
(5.19.0-1001-raspi), and the new one in proposed (5.19.0-1002-raspi),
and both exhibit the same issue.
On Kinetic:
$ cat /proc/asound/cards
0 [Headphones ]: bcm2835_headpho - bcm2835 Headphones
bcm2835 Headphones
On Jammy:
$ cat /proc/asound/cards
0 [b1 ]: bcm2835_hdmi - bcm2835 HDMI 1
bcm2835 HDMI 1
1 [Headphones ]: bcm2835_headpho - bcm2835 Headphones
bcm2835 Headphones
