le 9.2.6 => le 10 on kvm = no ability for hdmi sound output [invalid]

daggs · July 16, 2021 at 9:40 AM

Greetings,

I've tried to upgrade my le inside my kvm from 9.2.6 to 10, after upgrade, there is not relevant entry for hdmi audio anymore.

with pa, I can see only the bluetooth disabled output, with alsa, only the O/B card.

it seems to me that something is missing here, any ideas?

I'm using this device: USB - HDMI-CEC Adapter

Thanks,

dagg

dmesg | grep -i hdmi from le10 shows this:

Code

snd_hda_codec_hdmi hdaudioC0D2: No i915 binding for Intel HDMI/DP codec

while the same output on 9.2.6 returns this:

it looks like a config issue

looks like it and issue with the emulation, I'll mark it as invalid
