bluetooth: Google Nest not working

[Paul Menzel]

Connect a Google Nest to a ASUS laptop running Ubuntu 20.04, the devices pair, and *Office Speaker* shows up as an output device in the *Sound* settings, but no sound is heard (also doing the speaker test).

In Debian sid/unstable with GNOME Shell 41.2 and *gnome-bluetooth* 3.34.5-4, there is one more row in the audio settings allowing to set up some codecs. After changing that around, it finally works.

Ubuntu probably needs something similar.

This is not my system, so I cannot debug a lot.

Linux kernel 5.4.x is used, and Linux logs hci related messages, and bluetoothd also segfaults. (Ubuntu noticed the crash, and should have uploaded the resulting dumps.)

What fixed it was using `a2dp.py`:

```

Comparing Ubuntu 20.04 to Debian Unstable probably isn't fair because the former is a couple of years older. Please try either Ubuntu 21.10:

  https://ubuntu.com/download/desktop

or the preview of Ubuntu 22.04:

[Paul Menzel (paulmenzel)]

I understand, that bugs are probably fixed in newer versions.

https://ubuntu.com/#download still offers Ubuntu 20.04 for desktops, and even highlighted green. So what functionality can users expect?

Anyway, I just wanted to report it, and, as it is not my device, I am also unable to debug more.

[Daniel van Vugt (vanvugt)]

Generally Ubuntu 20.04 is more recommended because it is LTS (long term supported). I was only suggesting 21.10 or 22.04 because those would be more in line with what you see in Debian Unstable. Although I just tried 22.04 and find it's still not as up to date as Debian compared to the screenshot in comment #1. That will change in the next couple of months.

I'm still not sure if gnome-bluetooth is the correct component here. Ubuntu 22.04 already has gnome-bluetooth 3.34.5-4 which is the latest.

[Daniel van Vugt (vanvugt)]

We also have the latest BlueZ in Ubuntu already.

Maybe PulseAudio needs to be added here because that is where Bluetooth audio is implemented.

[Paul Menzel (paulmenzel)]

Yes, thank you for assigning the right component.

Personally, for desktops, I would always recommend the latest release. I think a lot of users do not know the difference, and just click the green button.

> We also have the latest BlueZ in Ubuntu already.

Do you mean 21.10, which has 5.60-0ubuntu2.1? Ubuntu 20.04 has 5.53-0ubuntu3.4.

Also, as written, `bluetoothd` seemed to have crashed several times, and the user allowed the crash reporter to upload the traces. Where can those be found?

[Daniel van Vugt (vanvugt)]

I mean in Ubuntu 22.04, BlueZ is version 5.62.

The system was updated from Ubuntu 20.04 to 21.10, but it’s still not working out of the box without the script `a2dp.py`.

I am not able to work more on the issue, as I do not have the environment, but maybe Canonical and Google should work more closely together on the QA side.
