I had the Sep. 16th version Ubuntu desktop image file downloaded via the Oowow for my Edge 2 device. Installed the ubuntu and it seems to be working fine except the audio.
The desktop top-right corner has the audio volume control bar available, but it does not really turn on any sound for me. I further checked the settings → sound → output → output device. There is only one option in the audio device list - which is “Audio Jack”.
I am using an HDMI cable to connect my Edge 2 device with my Samsung monitor. The HDMI cable definitely works for carrying sound as I used it for my Windows PC and laptop.
Any idea why the Edge 2 Ubuntu desktop does not have the sound working out of box?
Weird, after a night, the system has more items show up in the Audio Output dropdown. Now I can see these following options:
Combined HDMI + DP Output
I can see the HDMI Output has reactivity while I play some youtube video. It seems there is a sound coming out through the HDMI Output, but I just can’t hear anything. The device is connected via DP cable → HDMI → Monitor → Speakers.
I am using ubuntu 22. Pulse audio is on automatically and was not picking up hdmi in the Settings it only listed dummy. I terminated the server using the drop down on the bar. Then in settings it showed hdmi. Hope this helps.
Yeah, I have the same problem. Even the audio is working now, it does not pick up the current available output source. For example, I am switching between HDMI and DP as the display output. The system does not memorize the last selected audio outpout setting, or it does not detect which output source is currently available and automatically switch to it.
I see what you’re saying. I’m not sure where this lies exactly but it sounds like an Ubuntu issue. I never use the pulse audio and I’ve used Linux since they added it. So between Ubuntu or pulse there has to be some config. The only other thing I can think of is the khadas isn’t actually picking up the change. I have usbc and hdmi. I’ll check mine and see if i can play with the connections and audio.
