Mono BT headset has no in-call audio on recent rc-proposed

[John McAleely]

MX4/arale
ubuntu-touch/rc-proposed/meizu.en #387

Flash phone with --bootstrap, and walk through the welcome wizard. Once you have a phone to use, visit the BT settings, and pair a mono 'HSP' headset. In my case an old Jabra OTE-1.

Once the device is paired, make an incoming call to the handset. Use the headset button to answer the call.

The handset transitions to showing you an in-call UI, and appears to claim the audio is routed to the headset.

I heard no audio.

Expected: Audio was heard on the headset during the call.

Note that this does not occur on rc-proposed/meizu.en #381, so it seems to be a recent regression.

I discovered this apparent regression while testing the silo 60+37 combo @koza is using to land bluez 5.41, but note that the bug appears (and then disappears) on vanilla 387 vs 381.

I plan to capture logs, following the instructions here:

Here's a set of logs from #381, where the bug does not reproduce.

[John McAleely (john.mcaleely)]

I have tried to reproduce on both 387 & 389. I have been unable to, using the same equipment as last night.

I did not enable logging, so it does not seem to be the presence of extra logging that stops reproduction.

Status changed to 'Confirmed' because the bug affects multiple users.

Ubuntu Touch is no longer supported.
