Comment 21 for bug 1869819

For what I observed (both focal and bionic), I'm not sure (and I think it's not) it's a regression, due the the bug it's already there before this patch. And I tried one hp dm, one hp sff, one hp laptop and one dell laptop, only can be reproduced in Dell laptop.

For what I observed:

[[[1:11.1-1ubuntu7.5]]]
Before I plugged headset there is only one device shown on input device, which is

1. Internal Microphone - Built-in Audio

After I plugged headset into the jack, dialog shown up, I choice "headset", then three input device shown up, which are:

1. Headset Microphone - Built-in Audio
2. Internal Microphone - Built-in Audio
3. Microphone - Built-in Audio

[[[1:11.1-1ubuntu7.6]]]
Before I plugged headset there are two devices shown on input device, which are

1. Headset Microphone - Built-in Audio
2. Internal Microphone - Built-in Audio

After I plugged headset into the jack, dialog shown up, I choice "headset", then three input device shown up, which are:

1. Headset Microphone - Built-in Audio
2. Internal Microphone - Built-in Audio
3. Microphone - Built-in Audio

[[[result]]]
No matter which cases, once you choice (3. Microphone - Built-in Audio), then there is no headset output audio. Select others, the audio output came back.
