Yet the HDMI is still listed in the outputs. Hmm.Andy wrote: ⤴Sat Jan 14, 2023 3:22 am Hi, yes the HDMI and bluetooth were both showing and working in Sound, then I loaded the v6 kernel and added the sof firmware as per the instructions which were with the files I downloaded.
That brought up the internal sound card ES8336, and the bluetooth remained, but the HDMI disappeared.
I have been helping someone with a known computer model and it turns out there is an additional piece of hardware (I forget what it is called) in between the ones for which the firmware and drivers are loaded. That piece does not yet have open source drivers available (it is proprietary hardware, but they apparently are working on making the drivers available) and is a known issue to hearing sound in that other computer model. In that case the sound is being generated, but when it reaches the piece with the missing driver, it stops and thus can not make it to the end point of being heard.
I mention that because I can not see anything obvious in the latest output you posted which might indicate a problem with your install. (However, I am also not an audio wizard so maybe I am just missing something.)
But still no sound out of the headphones.
The 6.1-oem kernel just became available. We can see if that helps with this issue. You can install the latest 6.1-oem kernel with
Code: Select all
sudo apt-get install linux-oem-22.04c
If it does not work, post the output of
Code: Select all
journalctl -k | grep -Ei "ALSA|HDA|sof[-]|HDMI|snd[_-]|sound|hda.codec|hda.intel"
