Hi,

I was used to switching between laptop speakers and Bluetooth speaker on the normal audio menu.

But one day, I needed to use a TV’s speakers through HDMI, and couldn’t find it, so I initially thought it was a driver issue, but never found a fix, so I had to use a friend’s Windows laptop at the last minute because people were waiting to watch something.

Today, months later, I have the same issue, but on a different laptop with more recent hardware, so I was hoping to have better luck, and I didn’t… Until I accidentaly notice that the HDMI device is available under a submenu of the laptop’s speakers, WTF ?

Attached to this post is a screenshot showing a Bluetooth speaker, the laptop’s speakers and HDMI speakers. Why isn’t the latter available at the same location as the former two ?

The submenu could be kept for selecting between 2.0/5.1/7.1, just like for Bluetooth devices it’s used to select between aptX/LDAC/SBC, but I don’t understand what’s a whole different device doing in that submenu of the laptop’s speakers.

Thanks

    Yeah, I can see how it would be confusing. Your internal sound “card” is managing several outputs (profiles) and settings are per device rather than profile.

    I’m sure there’s a way to detect the HDMI plug/unplug and script an action to un/mute the audio. If you’re connected to the other external speaker, that action could be confused, so you’d have to account for that.

    I’m not expert in that department, but udev is where I’d start.

    Here’s a link to someone trying to trigger action on HDMI events that could get you started down the right path: https://forums.raspberrypi.com/viewtopic.php?t=343614
